I came across browsing the old discussion about DH-485 in SLC 5/01 in this web site (sometime in April to May 2001). It just happened that I am about to use this set-up now. I am just curious about this communication protocol. If SLC 5/01 is using a DH-485 to communicate with other devices (such as a PC with a 1784-PKTx card or 1784-KR card which has DH-485 options), is it possible to
connect it directly to the PC? Why do I need to use a device such as an isolated link coupler (or 1747-AIC) to communicate to a PC with a 1784-PKTx
card if the function of the AIC is as an isolator/splitter? And if this is a DH-485 protocol, can I multidrop this? Can anyone give me the pin configuration of the socket (RJ-45) of the SLC 5/01? I have a bunch of connectors/crimper and cables for this type of sockets (RJ-45) and if someone can send me the exact configuration of the socket, I might as well have to experiment this. Thanks in
advance..
