"But they will ONLY work with DH485 protocol (either RS232 or RS485 electrically)"
Geeze, that's right. I got my 485s confused. I really should know this stuff by now. I'll get a little burst of SLCs, then I won't see any for a year. Most of the time all I do is hook up to the PLC to troubleshoot.
So let me ask the question this way: You walk up to a SLC 5/03 connected to a PC through the DB9 connector on the PLC, and the same on a card on the back of the PC, about 25' away. The PC is a Windows 7 machine, and it is old and abused and the customer wants to replace it with a newer, more reliable machine. You don't have to worry about the driver end of things. The machine's manufacturer will install the driver remotely. You just have to pick out the card to put into the PC to insure the communication with the SLC will be possible. How would you go about making a recommendation of which card to purchase for the new PC?
(Btw, I have a whole backpack full of Mark's adaptors, along with a bunch from TW Controls)
