I am having trouble with the Discovery Response signal and am unsure on how to fix it.
Current setup: I’m sending an RDM Discovery signal with a DMXcat (controller) to a PSoC 4 controller (responder) with a rs485 shield to receive the data. The rs485 shield is in TX_CTRL mode, this would mean that the switch between TX and RX mode is made automatically by the shield. I am correctly receiving the Discovery signal on the responder but seem unable to return a response. I hardcoded the response in an array according to the standard in the E1.20 sheet. It consists of 8 Preamble bytes, 1 preamble separator byte, 12 EUID bytes and 4 encoded checksum bytes. The Problem: After sending the response I am unable to see any feedback as to what happened to this response. I am unsure what is causing the response to seemingly get lost. I have a couple of ideas as to what could be the issue but I don’t know how I’d be able to test if these ideas are true. Possible solutions: From what I can tell, the issue could be caused by a few things:
The main question: The main questions are mostly centered on what could be an issue with sending the response and what is a good RDM sniffer. Thanks in advance. |
