Troubleshooting the IRTrans LAN module

In the vast majority of installations, the IRTrans LAN module works out-of-the-box, and nothing has to be configured at all.

However, the easy setup requires an DHCP server running in your network. DHCP assures that your IRTrans module gets an IP address which fits into your network. DHCP is a pretty common function of a (Wi-Fi) router, so in most cases you don't have to think about IP addresses.

By default, the IRTrans module looks for an DHCP server on the network. If none is found, the module falls back to the IP


1st Check: module is working at all?

Make sure that you have connected the IRTrans to a proper power supply. The electrical specifications can be found in the PDF which comes with the module or online: IRTrans Ethernet Manual. When connecting to power, the LED of the module should flash green/red once. Now, even without any software involved, the module must respond to any incoming IR command: 

  • take any of your IR remotes
  • hold the remote towards the IRTrans (1-20 ft.)
  • press any key on the remote
  • -> the IRTrans should flash green once or as long as you hold down the remote's button

If this basic check is not working, you have a problem with the power supply or the module is defective. While this is very unlikely, please contact in that case.


No DHCP server? Need manual IP address?

The IRTrans falls back to the IP if no DHCP server is found. To configure the IRTrans you need to connect to the module's webserver: "http//". However, if your PC/Mac is not on the same network segment, i.e. the IP address differs in more than the last digits (192.168.0.XXX), then you will not be able to connect to the module. 

If you are running Mac OS X 10.5 (Leopard), please see "IRTrans LAN setup on Leopard", where you are guided to change your Mac's IP network settings.

If you are on a PC, ..... you are on your own. I am sorry, I am Mac guy, but eventually someone will help me to make a guide for XP/Vista setup, too.
