Title: Serial Cord for a WBA acceptor Post by: SLOTMAN on September 13, 2011, 09:18:33 PM I would like to sniff the traffic that some of JCM's test and diagnostic software sends to the acceptors for tests. I have a RS232 tap that I would also like to monitor the traffic and see what hex or binary code is transmitted. I am trying to do this on Unidesa machines.
My question is: What is special about JCM's adapter other than it injects 12V on to the cable? I am looking at the pin out configuration for the unidesa machine and it looks pretty straight forward TXD1 Pin3 RXD1 Pin2 GND Pin5 12out Pin7 DTR1 Pin4 This seems to be a simple DTE/DCE but I cant get it to communicate. The Unidesa harness allows it to be hooked to a power supply so the BV is powered up. Any insight on this would be greatly appreciated. Thank you |
