Question:
|
What's new in the product? |
|
Answer:
|
In our second production run, shipping April 2012, we've added:
- Additional voltage regulation in the 24V models (to
prevent POE overvoltage if an external charger is connected)
- Thermal protection.
- Additional surge protection in all models.

|
Question:
|
What will/won't the product do? |
|
Answer:
|
The injector is not a solar or
wind controller. If AC power fails,
the injector will immediately switch to battery power and provide POE
by drawing power from the battery string. In the
-48V units, output voltage approximately 0.5V lower than the
external DC battery input
voltage per the 802.11 standards. Because of the tight
voltage tolerances necessary for certain 24V equipment, the 24V
POE injector includes an additional voltage regulator which
prevents the POE voltage from exceeding 24.0V.
The injector does not contain a hub, switch or router. RJ-45 POE
jacks are simply loop-through. Each port (including the control
port) is completely
independent from the others. All ports are 10/100, and are not
Gig-E compatible.

Question:
|
What is the default IP address? How do I reset to defaults? What is the default password?
|
|
Answer:
|
If you have lost the IP address or admin password,
follow this procedure to reset to the default IP address of 192.168.0.100:
- Press and hold the reset button for 2 seconds to reset the network settings, user name and passwords.
The default master login is "admin" and default password is "1234". This procedure resets the admin login and IP
address and lockout, but doesn't affect outlet names and links.

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, use a crossover cable and follow these steps
to reach the controller’s IP.
- 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:
|
Can you explain the auto-ping settings?
|
|
Answer:
|
Enabling auto-ping
To enable auto-ping, the check-box to the left of the IP address must be checked, then the change
button pushed. You will get a message "Autoping will automatically be enabled after 10 successful
pings". This prevents rebooting units before conditions are properly established.
Time Between Pings
The time between which each ping is set. The time between pings to a particular device
is (Time_Between_Pings * Number_of_devices_enabled_in_the_ping_list).
Ping failures before reboot
Number of times the ping has to fail (in a row) on a given device before it is power cycled.
Times to attempt reboot
Number of times to attempt power cycling before giving up and disabling auto-ping.
Device reboot delay
Length of time after a power cycle before checking for a response from the device.
This allows a device or computer time to completely boot up.

Question:
|
How can I control the switch from my own applications?
|
|
Answer:
|
Download the latest User Utility.
Your application can use HTTP or serial port communications. There is also a C++ example with source (4/11/06 - 483k).
This program displays the controller name, switch names and switch status via HTTP. You can also toggle the switches on and off.
Also included is PowerMan support for Linux.
Windows users can download a Perl interpreter to run the script version.
This script (ver 4.0) is compatible with all DLI power controllers.
