When I connect TC35i modem to PC via USB-to-RS232 converter everything works greate. Doing "Prepare PLC-side modem" in Modem Services in VisiLogic OPLC IDE result in connection and success. Making a test dial from Modem Services also results in success.
But when I connect my PLC (it is V560) with the modem using a 4-wire RJ11 programming cable (ended with MJ10-22-CS25 and simple Male-to-Male adapter) then the Modem Init fails and SB 83 bit become 1 (SB 83 is Modem Init Fail for COM 2).
I suppose that something wrong is with the cable. How am I supposed to connect V560 to TC35i?
Thanks for help...
