Generic RS485 USB Adapter & LOR RJ45 (8P8C) Pinout

[lightingman117]

Confirmed: Generic USB to RS485 or RS232 (with converter) as COMM (COM) port works for LOR network.

Not tested: Max Distance to first unit (or subsequent units)

 

LOR Controller - Ethernet - Cat5e - Pinout (T568B):

1. OW - DMX Data+
2. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎O - DMX Data-
3. GW - +9V
4. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎B - LOR Data+
5. BW - LOR Data-
6. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎G - LOR Gound
7. BW - DMX Ground
8. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎B - Unused

 

Methodology & Info:

I tested with HW utility & a single controller with ~6ft Cat5e cable.

I used a B+B WORX USPTL4-LS for the USB>RS485 test

I used a UGREEN FTDI based USB>RS232 (I think model 20218) with DTech DT-9003 RS232>RS485 converter

Not Tested: Prolific chip

 

Why:

Can't find my USB485B or USB485 LOR converters. The show must go on.

To clarify this, a LOR controller does not have separate pins for DMX. A LOR controller (at least the AC and DC controllers) only use pins 3,4,5,6. If the controller receives a DMX signal on pins 4&5, it will switch to DMX mode.

Thank you for catching my mistake.

I wish I could edit the OP. Perhaps with more post count the forum will open-up.

I cannot seem to find a LOR RJ45 Pinout Reference document. I would really like to have direct sources for this info.

 

Attached is an .xlsx with various pinouts.
