Question:        What is the current version of firmware?

Answer:           The current version is  on the update page  Find the revision history here, and firmware update instructions here.

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.

    Question:        Can you develop custom firmware for my application?

    Answer:         Gladly.  We've done this for many customers.  Our programming rate is $75/hour.  After we agree on a -very specific- project description, we can send you an estimate of the time involved to code, debug and test.   

    Question:        Can you develop custom hardware for my application?

    Answer:           Gladly.  We've done this for many customers.   Please call with your requirements

    Question:        What are the current and voltage ratings?

    Answer:           Voltage input is 90-240VAC auto sensing.  Total current is limited to 15A by circuit breaker.   Electrical codes in some areas may prohibit use of standard L-15 plugs and outlets on other than 120VAC circuits.

    Question:        Do you support PowerMan?

    Answer:           Yes, absolutely.  The latest code is added to the tarball.  Download the latest User Utility here.
