Question:      What's the Hardware Revision History?
Answer:  In our second version, DIN Relay II, with serial numbers DIN22000 and higher, we added these features:
  • Relay anti-chatter protection.  Maximum relay switching frequency is limited to ~2Hz for safety and longevity.
  • Variable coil current control.  Relay holding and pull-in currents are regulated for improved efficiency.  Power consumption has been reduced by more than 40% from earlier models.
  • Watchdog supervisor.  We've added a second processor which continuously monitors the microcontroller and reboots it gracefully if necessary.
  • Increased memory. Non-volatile memory has been increased from 16kb to 256kb.  No memory expansion board is required for script storage.
    •

In of  DIN Relay III, we added these features:

  • DC input voltage rating now increased to 48VDC
  • Added audio alarm-beeper
  • Added 2x16 LCD to display status and help with setup.
  • Added internal real-time-clock with NTP and local time synchronization
  • Numerous firmware upgrades including scheduling feature , increased AutoPing speed limit and added more scripting commands.
  • Increased relay contact rating and durability
  • Added keypad for local control
  • Updated rating, testing, and specifications for higher DC input voltages
  • Eliminated the internal RJ-45 bulkhead for more reliable connection to unshielded RJ-45 plastic plugs. Connection status displayed on LCD.
  • Case color has changed, manual and box are updated, power consumption has increased slightly

In version 3.1, we added these features:

  • Added RS-232 web console for remote machine control. The +5 supply has been removed.  RS-232 has 2.5kv isolation and is brought out to three screw terminals in the upper right hand corner.
  • Added internal UVLO (Under Voltage Lock Out) for more reliable operation on battery power.  UVLO starts at 11.5V and shuts off at 10V to prevent battery damage.  This feature is designed to augment an existing UVLO/OVP charge controller in battery powered applications.  It is not a substitute for a solar/wind charge controller and doesn't guarantee proper reset of attached devices in the event that a battery is highly discharged.
  • Minor internal improvements.

In version 4, we completely redesigned the unit and added a host of new features:


Note: version 4 supports input supply voltages from 12 to 28VDC. If you require 48V or AC mains power, please contact sales for a variant product.
RS-232 has been removed in lieu of the sensor port and ADC inputs.

Question:  Whch temperature sensors are compatible?
Answer:  The DS18B20 or DHT-11 sensors with RJ12 plugs are compatible and in stock.  Find a Lua thermostat code example here.
Question:  What is the polarity of the connectors?
Answer:  The polarity is stamped above the conenctor. It may be eeasier to see if they are removed.

Question:  What are the contact ratings?
Answer:  All eight internal T-90 Relays have the following ratings:

Relay Contact Ratings

Voltage

NO

NC

240VAC

40A

30A

277VAC

30A

15A

30VDC

20A

10A

250VAC

1HP

1/2HP

Relays are rated at 250,000 operations MTBF at 50% load.  Case terminals are rated at 8-12A, depending on agency.  Only stranded wire of appropriate gauge should be used.  Terminals must be well torqued, but not over 10in/lbs.  It is wise to recheck torque after completing the installation.  Heavy traces and gold plating are used to minimize internal resistance between the terminals and relay contacts, typically 25m Ohms, so internal contact power dissipation is not normally a consideration. For maximum flexibility, relay contacts are unprotected.  For high current inductive switching, consider adding an external snubber circuit to extend contact life. Download contact protection information from relaycare.pdf

Question:  How do I connect the ADC inputs?
Answer:  Remove the accessory hatch. The plastic hatch on the right side of the relay can be opened to add a WiFi antenna or to connect analog inputs. Using a small screwdriver, press gently on the lower edge of the hatch. Push towards the buttons The hatch will flex and pop open.


The antenna and/or ADC connector may be attached when the hatch is removed. A three pin connector is provided for ADC input. The upper pin is scaled for 0-100VDC, and the lower pin is 0-10VDC. The center pin is a ground reference bonded to the negative power input.



* To release the ADC wires, press the orange tab down into the body of the connector by the wire to be released and remove the wire. A small flat-head screwdriver works well for this.
Question:  Where are the safety fuses in the unit?
Answer:  On the bottom of the relay circuit board are over-current protection fuses on all relay common lines for safety. If one of these fuses blow, the relay will still "click", but power will not pass through. They are 12A fast-blow fuses.  Fuse specs are here.
P/N DIN4-FUSE 10-pack available from DLI $7.95. Call 408-330-5599 option 1 to order.


Question:  What are the power requirements?
Answer:  The relay dissipates an absolute maximum of 5.8W during switching with all relays on.   Typical dissipation with relays off is 1.2W.  Although the case is well ventilated, ambient air temperature should not exceed 170°F for maximum reliability.  Surges over 35V may trip the safety fuse. 

The relay will shut down at input voltages below 10.5VDC. If you expect to encounter brown-out conditions in your application, set the Power-on-Recovery Mode on the setup page for safest operation.  To prevent oscillation, a brown-out re-latch function is also provided on the Setup page. In the event of a brown-out, you may specify a time period after which the relay will attempt to re-latch the contacts. This function is disabled by default and has no effect if the relay is properly powered.   Please read the UVLO and OVP suggestions below.

Add an external MOV or other protection device across the power input terminals in noisy environments.  We are working hard to make this the most efficient product in its class.

 The input is protected by a PTC thermal fuse and SCR crowbar which trips around 35V.  If the fuse blows, correct the over-voltage condition and let the PTC cool to reset.
Question:  How can I momentarily trigger (pulse) a relay?
Answer:  Three Examples:

Hardware
Just wire a capacitor in series with the circuit (assuming a DC load).  Simple.

Click "Cycle"
Press the existing cycle button in combination using the NC contact (instead of NO):


Custom Script
Name your circuit here:
 Create a button that starts a script starting on line #2:

Clicking "Open the Blinds" toggles pulses the relay per this script:. 

-- Open the Blinds
function open_blinds()
  outlet[1].on()
  delay(1)
  outlet[1].off()  
end
Try it at pro.digital-loggers.com:5002  admin/4321

You can also trigger scripts remotely. More on that here. REST API and MQTT.   The BASIC scripting language has been replaced by Lua.  A much more powerful watchdog supervisory processor has been added.  Most important, there's good news on price: the new, more powerful ICs are less expensive. Here's a feature matrix comparing the older Taifatech and newer Atheros power models.
Question:  Can I invert AutoPing or the Web Page to use NC contacts?
Answer:  or safety reasons and to prevent support issues, we have not implemented an "invert relay" function in either the web UI or AutoPing.  You can drive the relays in reverse by:

You can also use the programmable web links to start a script. 

Question:  What are the mounting dimensions and physical size? Do you have drawings?
Answer:   Download a top-level print here (.pdf).  Here are graphics of the front of the relay.
Question:  What components do I need to build a remotely powered DC site using the DIN relay as a power controller?
Answer:  In addition to the load (ie. APCam, PtP link, AP, etc), you'll need a battery, some source of power, ie wind or solar, and most importantly a charge controller with OVP and UVLO features.  Over Voltage Protection is needed for reasonable battery life.  Under Voltage Lockout is needed to correctly reset attached devices as well as the DIN relay and to prevent oscillation when the battery is deeply discharged.
Question:  Wiring and terminal information?
Answer:  Use stranded wire from 28AWG to 14AWG.  Find information on Phoenix connectors here.
Question:  What's a relay?  How can I wire it up?
Answer:  The DIN relay has dry contact FORM-C outputs.  They provide whatever output voltage you connect to them.  For example, if you connect a wire from the positive side of your 24V supply to the COM terminal, then the NO terminal will provide 24 volts when the relay is switched on, and the NC terminal will provide 24V when the relay is off.  You can operate the DIN relay on a different voltage than the relay contacts.  For example, the DIN relay could run on 12VDC, but switch 220VAC.  You can also use the relay to switch data, communications lines, or other electrical signals.  In a relay, contacts are electrically isolated from the coil.  The DIN relay controls the coil in the diagram below:


 
N.O. means Normally Open
N.C. means Normally Closed
COM means COMmon

Each relay is fully isolated, there is no internal connection between the relays. The word "common" describes the wiper of the relay itself which shares the NO and NC contacts in common. The COM pins on the DIN relay are not connected each other unless you elect to do so externally. Put simply, all relays are fully isolated.

Question:  What is the current version of firmware?
Answer:  Find the revision history here, and firmware update instructions here.
Question:  How does this model compare to the earlier wired-only models?
Answer:  These units have both hardwired Ethernet and WiFi, thanks to a more powerful 32 bit CPU from Qualcomm Atheros.  The design includes expanded memory for the Atheros including FLASH, EEPROM, and SDRAM.  Leveraging open-source code and expanded memory allowed us to add several firmware features including SNMP, HTTPS, SSL, SSH, Rest API and Alexa Compatibility, a REST API and MQTT.   The BASIC scripting language has been replaced by Lua.  A much more powerful watchdog supervisory processor has been added.  Most important, there's good news on price: the new, more powerful ICs are less expensive.

Question:  Where can I find more extensive and detailed help?
Answer:  Click on the Help menu link on the power controller itself.


Then click on the on-line help icon.
Question:  I have a different model: Web Power Switch 7, Ethernet Power Controller II, III, V, or  PC-8000 model.  Where can I find information?
Answer:  Jump to the support page here. Don't see what you need?  Just give us a call (408) 330-5599.
Question:  How can I control and customize the LCD?
Answer:  The LCD can be used to display settings, outlet status, or any message of your choice.  You can operate the LCD in "billboard" style, displaying a series of user defined messages.  To customize the LCD, you'll want to write a script using the Lua scripting language.   You can also use the display to send messages from remote systems (ie. service alert warnings).  To send messages remotely, write a script first, saving it in FLASH then start the script from your remote system.  Learn more about scripting here.
Question:  How can I set up autoping to reboot my modem and router, but have my router come on later?
Can I set outlets to cycle at different rates?
Answer:  OF course, this can be done via Scripts.
However, you can also make the outlets cycle at individual rates by using the REST API or UOM. Log into the power controller and be sure that the REST API is enabled.

Go to the Outlets in the REST API. e.g. http://192.1680.100/restapi/relay/outlets/
Select the outlet to set the custom cycle time on.


Select the cycle delay setting.


Set the custom cycle delay.


For example, you can set the modem delay to 15 seconds and the router delay to 45 seconds.
In this example, when Autoping cycles the outlets, the modem will come on after 15 seconds and the router will come on after 45 seconds.
Question:  Is this product compatible with the older (less secure) HTTP plaintext command syntax? 
Answer:  To use the earlier HTTP commands described here and CURL scripts that use plaintext login, you'll need to enable this legacy setting on the SETUP page:
Question:  What is the default IP address? How do I reset to defaults? What is the default password? 
Answer:  Follow this procedure to reset to the default IP address of 192.168.0.100:


    Press and release the reset button. After about 5 seconds, you will hear a beep, then use the up and down keys to choose the type of reset.
    The following reset modes are available:

    1. Clear lock bits: Clear protection bits only. Other settings are preserved.
    2. Reset Net&Script: Clear protection bits, reset network settings and admin login, disable autoping and scripts. Other settings are preserved.
    3. Reset + WiFi:   Clear protection bits, reset network settings and admin login, disable autoping and scripts, and enable open WiFi access. Other settings are preserved.
    4. Complete wipe: Reset all settings to factory defaults and remove any user files. All settings will be lost!
    5. Wipe + WiFi: Reset all settings to factory defaults and remove any user files, then enable open WiFi access. All settings are lost!
    6. Reboot: Reboot only. All settings are preserved.  (firmware versions 1.12.14.0+)

    To activate the selected reset mode, press cycle or the reset button and hold it.

     

    The default master login is "admin" and default password is "1234".  The default IP is 192.168.0.100.


    If all settings are reset (the two last 'wipe' reset modes), the Subnet Restriction will be enabled to prevent remote access using the default password. ONLY MACHINES IN THE SAME SUBNET WILL BE ABLE TO CONNECT AFTER RESETTING TO DEFAULTS.
    Besides setting your computer to a compatible network, you can also use the keypad to set it up.
    The keypad settings Pro/V222/DC3/ISO32 are slightly different from the keypad settings for the DIN and EPCR models.
Question:  On initial setup, I can't establish a Ethernet communications from a Windows PC.  Help!
Answer:  If your default Windows settings won’t access the controller, follow these steps to reach the controller’s IP.  You'll find a more extensive explanation in the user's manual. Details for setting up via the keypad can be found here.

Before adding an IP, close network programs and browsers.

Go to the Network Settings – Local Area Network or use the keyboard shortcut <Windows-R> - type “ncpa.cpl” and click OK. 

Right click on your LAN connection and choose “Properties”

Highlight “Internet Protocol” and click the “Properties” button.

Make note of the current settings.

Select "Use the following IP address".

Enter an IP address such as 192.168.0.5.

Enter a subnet mask of 255.255.255.0.

Delete any gateway entry.

Close all windows for the configuration to take effect.

Start your Browser and type 192.168.0.100 in the URL field. The index page should be displayed.

The default user name is "admin" (lower case) and password is “1234”

Set the IP address of the unit to your network, then restore your settings.
Question:  How can I change the NTP servers?

Enter a time in seconds.
3600 = 1 hour
7200 = 2 hours
86400 = 1 day
604800 = 1 week
31536000 ~ 1 year

Click the PUT button.

The next time you login, the timeout will take effect.
Question:  Can I increase the internal system log size?
Answer:  Yes, but this must be done using the SSH shell.

Log into the unit via SSH.
The default is 16KB; to make it 64, use these commands:

uci set system.@system[0].log_size=64
uci commit system
/etc/init.d/log restart

*Note that this will clear the log.
Question:  How to I install a supported VPN?
Answer:  Currently OpenVPN, Tailscale, ZeroTier, NetBird and innernet are supported in the latest firmware.
These must be installed and configured using SSH.

OpenVPN:
cd /tmp
opkg update
opkg install openvpn

Edit the /etc/config/openvpn file
https://openwrt.org/docs/guide-user/services/vpn/openvpn/client
/etc/init.d/openvpn start

*The configuration is retained across firmware updates, but the package must be reinstalled.

The VPNs options below require firmware 1.12.7.0 or higher. (Firmware 1.12.11.0 or higher recommended)

ZeroTier:
cd /tmp
opkg update
opkg install zerotier

edit /etc/config/zerotier and write the network ID
/etc/init.d/zerotier restart
The device appears in the net in the zerotier web UI control panel but isn't authorized (and thus has no IP)
Tick the Auth checkbox, and it gains an IP.

*The configuration is retained across firmware updates, but the package must be reinstalled.

Tailscale:
cd /tmp
opkg update
opkg install tailscale-combined
tailscale up

You will be prompted to authorize the device (copy the URL and paste into the browser):

*The configuration is retained across firmware updates, but the package must be reinstalled.

NetBird:
FIRST prepare a netbird account AND verify the email (activation will otherwise fail).
cd /tmp
opkg update
opkg install netbird
netbird up

You will be prompted to authorize the device (copy the URL and paste into the browser)

*The configuration is retained across firmware updates (1.2.7.0+), but the package must be reinstalled.

Innernet summary: (requires 1.12.9.0)
This release includes two new installable packages, innernet and innernet-server supporting, as of now, Linux and Mac OS only (no Android, Windows, etc.).
They enable you to build kernel-mode-routed mesh networks based on the Wireguard protocol, but there's no central server: you need to host it yourself by installing "innernet-server" on a device with a public IP, installing "innernet" and following the documentation (both packages have a text-mode user interface for configuration).
The summary is that it may be tricky to configure and limited to UNIX-like systems, but shaves off ~15% of median ping time, reduces RAM usage and CPU load, and isn't controlled by third parties.
Question:  How can I clean up old certificates from prior firmware versions?
Answer:  Beginning with firmware 1.12.14.0, you can get a list of certificates not shipped with the current firmware via the RESI API.
http://192.168.0.100/restapi/config/certificates/all;custom=true/
or curl e.g.:
curl -u admin:1234 -H "Content-type: application/json" --digest http://192.168.0.100/restapi/config/certificates/all;custom=true/
You can delete selectively via SSH or the REST API.

To delete all certificates not shipped with the current firmware via curl e.g.:
curl -u admin:1234 -X DELETE -H "X-Requested-With: XMLHttpRequest" --digest http://192.168.0.100/restapi/config/certificates/all;custom=true/

Alternatively, a full reset will clear them.
Perform a complete backup, except uncheck the "Trusted certificate and revocation list store".
Perform the full reset (complete wipe).
Restore from backup.
Question:  How can I install my own certificate?
Answer: 

Your certificate and key must in PEM format with the certificate being the full chain.

Once created, login via SSH and place them into /etc/uhttpd.key and /etc/uhttpd.crt, respectively.
Next run:
/etc/init.d/uhttpd
restart

Question:  When I unplug the Ethernet cable, WiFi quits working.
Answer:  This happens when the Wired and WiFi are on the same network and subnet.
1. Change the LAN Metric to 1. This resolves most of these issues. (Firmware 1.9.8.0+)



If you plan to run the WiFI and Ethernet on the same network continually or still have issues;

2. Change the last character of the WiFi MAC address.
e.g. http://192.168.0.100/restapi/network/wireless/mac_address/

Changing the last HEX number is all that is required.
Question:  How do I fix: email notification failed: [CURL-EASY][COULDNT_RESOLVE_HOST] Couldn't resolve host name (6)?
Answer:  1. Verify that "Same subnet only" is unchecked in the General Network Settings
2. Verify that a gateway is entered in Network Settings
3. Verify that a DNS server are entered in Network Settings
Question:  How do I fix: [CURL-EASY][PEER_FAILED_VERIFICATION] SSL peer certificate or SSH remote key was not OK (60),
Peer certificate cannot be authenticated with given CA certificates (60) or
Certificate renewal error "failure while reading service directory".
Answer:  If the firmware version is below 1.9.x, then update the firmware to support the latest certificates.

Otherwise, log into the unit via SSH.
Type:
ls -l /etc/ssl/certs/

You'll likely see the .crt files but no symlinks like 12345678.0 -> XXX.crt.
Type or copy/paste:

rm -f /etc/ssl/certs/[0-9a-f]*.[0-9]
uci delete system.__dliconf_trust_all_known_root_ca_certificates
uci commit system
sh /rom/etc/uci-defaults/trust-all-known-root-ca-certificates

uci: Entry not found      < -- This is normal
then check that
ls -l /etc/ssl/certs/

shows the symlinks have appeared.
Question:  How do I clear "SECURITY LOCKOUT IN PLACE" when I try to login?
Answer:  When you enter an incorrect password or use an old "hidden key" too many times, you may be *locked out.

In the Settings page is a "Delays" section. The duration of the security lockout is set there:


There are a few ways to end the lockout.
Option A. Don't access the unit until the lockout expires

There are three ways to end the lockout prematurely without power-cycling.
Option B. Press the reset button and choose option 1 or option 6:
Press and release the reset button. After about 5 seconds, you will hear a beep, then use the up and down keys to choose the type of reset.
The following reset modes are available:

1. Clear lock bits: Clear protection bits only. Other settings are preserved.
2. Reset Net&Script: Clear protection bits, reset network settings and admin login, disable autoping and scripts. Other settings are preserved.
3. Reset + WiFi:   Clear protection bits, reset network settings and admin login, disable autoping and scripts, and enable open WiFi access. Other settings are preserved.
4. Complete wipe: Reset all settings to factory defaults and remove any user files. All settings will be lost!
5. Wipe + WiFi: Reset all settings to factory defaults and remove any user files, then enable open WiFi access. All settings are lost!
6. Reboot: Reboot only. All settings are preserved.  (firmware versions 1.12.14.0+)

To activate the selected reset mode, press cycle or the reset button and hold it.


Option C. Login via SSH and type:
reboot

Option D. Login via SSH and type:
/etc/init.d/generic_state_server restart

* To help prevent lockouts: With each visit to the login page a secret key is generated. If another key is generated because someone else brought up the page after you did, then the key has expired. Before logging in, press the F5 key to refresh the browser if it has been some time since going to the login page. If you make a mistake on the password and press the "back" button on the browser to go back and try again, press F5 to refresh the page and get a new key. If you don't do this, you are using the old key and will get locked out.
Question:  How do I fix a "Host request header not present or not recognized" error when I try to login from a different network?
Answer:  Firmware 1.12.12.0+ supports "Host request header filtering for DNS rebinding protection".
Login via a local IP address and check the "Allowed Hostnames setting in the general network settings section.
If the top field empty, enter an asterisk ( * ) in and submit the changes. For better security, see below:



If the unit is accessible only via a private (e.g. RFC1918) IP address, a malicious site can manipulate its DNS entry to trick your browser into sending a request to the private address. Host header restriction can used to prevent such DNS rebinding attacks. The default permitted list contains just the wildcard "*" for backwards compatibility. To enable the protection, add patterns for hostname(s) you use to address the unit to the list and remove the "*" wildcard.

AFTER REMOVING THE "*" WILDCARD, THE UNIT MAY ONLY BE REACHED VIA HOSTNAMES MATCHING THE PATTERNS LISTED, OR BY ITS LOCAL IP. If connectivity is lost, use a local connection as discussed above and use the explicit IP address, which always is an allowed Host header value.

Hostname patterns support the following special sequences:
"*" stands for any sequence of characters, e.g. "*.example.com" will match "pcr.example.com" and "another.pcr.example.com"; "${hostname}" stands for the current unit hostname (as configured), and will usually be used for as part of a fully-qualified domain name (e.g. "${hostname}.example.com") for uniform configuration between several units.
Question:/i>  My program used to run fine on an earlier model, but won't run on this one. What can I do?
Answer:  It's possible that the program requires legacy login methods which accept plaintext authentication. Go to the Setup page and tick the "Allow legacy plaintext login methods" checkbox, then click "Submit".
If the program works, please inform the author that the preferred authentication method is by using the more secure challenge/response mechanism. Have a look at the Rest API here for new development. 
Question:  I can't access the controller from another network. Autoping will not ping an external server such as 8.8.8.8. How do I fix it?
Answer:  1. First make sure the "Same subnet access only" is unchecked in the General network settings



2. Next, verify that the network gateway is correct. It is usually the same gateway as your computer uses.

Gateway

The issue should be resolved.



If the issue remains (very rare):
3. Enable SSH
 
Login via SSH and type route
Look for a default route entry as shown here: 

#route 
Kernel IP routing table
Destination    Gateway         Genmask        Flags  Metric  Ref  Use  Iface
default        192.168.11.1    0.0.0.0         UG      0      0    0   eth0
192.168.11.0   *              255.255.255.0   U       0      0    0   eth0
Only if you don't see a default route and items 1 and 2 are verified, enter these commands into the SSH shell.

/etc/init.d/default_route_manager stop
/etc/init.d/default_route_manager disable
rm /etc/udhcpc-filters/500-divert-default-route-updates
/etc/init.d/network restart

*Let support@digital-loggers.com know that these default_route changes were made.
Question:  Can you develop custom firmware for my application?
Answer:  Gladly.  We've done this for many customers.  After we agree on a -very specific- project description, we can send you an estimate of the time involved to code, debug and test. In most cases, a kick-off meeting in Silicon Valley is required.
Question:  Do you support HomeSeer?
Answer:  Yes! Alex Khassapov has created a plugin for HomeSeer.
Question:  Can you develop custom hardware for my application?
Answer:  Gladly.  We've done this for many customers.   Please call with your requirements.  To amortize NRE, practical minimum order quantities are typically 100-1000 units.  In most cases, a kick-off meeting in Silicon Valley is required.
Question:  Do you support PowerMan?
Answer:  Yes, absolutely.  The latest code is added to the tarball. Download the latest User Utility here.
Question:  What is the blue LCD for?
Answer:  The blue LCD shows outlet status during power up, the IP address, netmask, outlet names, and other useful information.  Time and date stamps for significant events (such as power outages or emergency shutdowns) are also displayed. Using the keypad, you can set up some of the features such as the network settings.  You can program this display to display your own messages using the scripting feature.
