Frankly, it looks more like COMM concerns than some DCC issues, I was wondering why you list DCC pins here, could you give us extra hints?

Since the words from RS-485/RS-232 Interface illustrate sth, there are two multiplexer circuit allowing the ability to switch between an RS-232 or RS-485 interface. This interface contains two independent RS-485 ports and two independent RS-232 ports. Each RS-485 interface is routed to a 2x5 0.1” header and a DB-9 female connector. One RS-232 interface is routed to a 2x5 0.1” header and the second RS-232 interface is routed to a DB-9 male connector. A jumper is used on the board to select between RS-485 port 0 or RS-232 port 0 and RS- 485 port 1 or RS-232 port 1. ,

Based on above, maybe you'd better help confirm the status of J8 first, is now J8 on DB9_MODE = LOW -> RS-232 SELECTED? just as the picture shows I linked here.
