Rifet Posted June 11, 2019 Report Share Posted June 11, 2019 ANSWER : I made it work! When I tried to connect basic 4 wire telephone cable to both end (modem and plc) it worked immediately. Seems that DB9 connector that came with modem kit had already cross crimped pins inside it. Guys help please, I can't initialize COM 2 so that I can connect my modem (Cinterion) to that port so that I could send message when error happens. I added few pictures so that you can see that my SB82 never goes active, why is that? I am using method stop - download - reset so that power bit goes on but port is not initialized Can port be initialized even if I don't have any device connected to that port? I am using Visilogic 1210 and Cinterion modem New edit: I found this in Cinterion documentation: "Now you can connect the modem to the PLC using the 9 Pin connector MJ10-22-CS76 via cable 4 wires." Does anyone has wiring schematic for this "9 Pin connector MJ10-22-CS76 via cable 4 wires". Here is how I connect modem to visilogic, is this correct?
