com issue is killing me

So my old LOR usb to ethernet adaptor is missing in action....Cant get a new adaptor in time due to LOR being swamped with orders:(...For the last two days I have been on the manhunt for a replacement. Thought I finally found one in this TredNet TU2-ETG usb to ethernet adaptor. This adaptor claims to be good for full or half duplex. So I install the drivers and go to the Hardware Utility to Auto Configure Com port. But still keep getting the "unable to locate LOR controller" message. Noticed that when I power up the controller the red led is blinking twice per sec as it should, but as soon as I plug the ethernet cable into the adaptor the L.E.D goes off completly. At this point I have friends coming over tomorrow to help finish the wiring and Im honestly about ready to call the whole thing off over this COM issue.....Any ideas would be extremly appreciated

Don't panic yet. have you sent a help request to LOR (its on their main web page) most of the issues can be resolved quickly, give this a try. ;)

First thing. Although LOR uses Cat 5 cable. The communications protocol that is sent over the wire is NOT Ethernet. The protocol uses is 485 which is a serial communications standard.

In the past some people have tried to hook controllers up to ethernet and have cause damage to the controllers.

The 485 communications protocol and the ethernet protocol use different voltages and are NOT compatible.

No one said "Go buy whatever you want, shove a cat-5 in it, and it will work"

One last time:

You dont HAVE to use a LOR adapter ( although I HIGHLY encourrage you to do so, because you would have to connect the Rj45 end to screw termianls, and you dont seem to follow instructions verry well)

you CAN use another adapter, but you MUST GET A RS-485 adapter.

I think the LOR adapter uses the same chip
