I picked up one of these on eBay and found that the serial port that you’d use to configure it didn’t seem to match anything that I had. I spent a little bit of time figuring out the pinout, so writing it up in case anyone else ends up with the same problem.

On the RJ-45 connector, Pin 6 is Ground, Pin 5 is Serial TX, and Pin 4 is Serial RX. These should correspond to Pin 5, 2 and 3 respectively on a DB9 connector that you will connect directly to a usbserial cable or the like. Maybe a rollover cable could have helped here, but I didn’t have one.

If you want to use the web interface, note that the default username is “Admin” and there is no password. You may need to reset to factory defaults to make that work.

Unfortunately, this thing is EOL’d and you’re going to still need some weird workarounds to make this happy with Java, e.g. run old Java and do: https://xiaoxiaoke.wordpress.com/2015/10/06/changing-java-security-restriction-for-network-connect-error-issue-in-kvm/

Since that site doesn’t want to allow archiving via the Wayback Machine, it’s contents copied below for posterity:

Linux:

  1. Open the file /etc/java-7-openjdk/security/java.security as superuser

  2. Comment out the line with the key jdk.tls.disabledAlgorithms

  3. Add this line below and save the file: jdk.tls.disabledAlgorithms=SSLv3, EC, ECDHE, ECDH

Windows:

  1. Add the KVM IP into the exception site list Open Control Panel -> Java In Java Control Panel -> select Security tab -> Edit Site List -> Add the KVM IP “http://X.X.X.X” Open the file as admin: Windows -> Program Files (x86) -> Java -> jre1.8.0_51 -> lib -> security -> java.security

  2. Comment out the line with the key jdk.tls.disabledAlgorithms

  3. Add this line below and save the file: jdk.tls.disabledAlgorithms=SSLv3, EC, ECDHE, ECDH

Alternatively, it works just fine with Java 7 update 80 if you’re already getting unsupported stuff. Downloading that from Oracle these days requires an account from them, which is a bit of a speedbump to getting the old binaries. If you don’t get the e-mail verification link the first time around (I didn’t), just resend it out and hopefully it’ll work the second time.

It’s probably best to run this thing on its own network and the tools within a VM, but it does work.
