DMX on K8-B

I'm switching one of my Falcon F4v2 controllers for a Kulp K8-B (need the extra expansion ports).  I need to be able to send DMX to an a/c controller from the K8-B.  I don't know how to physically connect it to the K8-B board, as it doesn't appear that any of the RJ-45 expansion connectors can be configured for DMX.  I may be missing something here, so please correct me, if I've got that wrong.  

Note that I'm running FPP 6.2.

Do I need to use the ttyS1 and ttyS2 headers on the K8-B to make the DMX connection?  If so, can anyone point me to a pinout diagram for such a DMX (using RJ-45) connection?

Specifically, I'm trying to connect it to an LOR box, so any additional hints you can provide will also be appreciated.

I've done a little more investigating.  Assuming I need to use the ttyS1/S2 connections, then I think this is the pinout information I need for LOR...  It looks like I'd connect pins 4, 5, and 6 on the RJ45 connector to the corresponding pins on the ttyS1 (or S2) header on the K8-B.

I'd be grateful if someone would check my work or tell me if I've got something screwed up.

You are correct. pin 4 for data+ would go to the + , pin 5 for data- would go to - and pin 6 would go to G for ground
