I have a main site that has a Micrologix 1000 Analog hooked to a NET-AIC module at the round din port and at the 9-pin D port there is a Data Radio Integra TR radio modem I think the radio is configured correctly because at the other site I setup a laptop and using hyperterminal and a straight 9-pin D cable I was able to type to my other computer and it could type back. I am told that using RSlinx and the configured 1747-PIC driver I should be able to see the node (PLC) at the other site. If I can't see the PLC then how could the other PLC see it, right? Maby I am using the wrong cable configuration? Please help............
