I've been looking at the WIC-1T and WIC-2T cards these last few days while totally confused. With the right cable, should I be able to connect to any device that supports serial connection then? That'd be pretty interesting, as I could then connect some interesting devices. I've also seen a cable that fits the strange WIC-2T serial port and has multiple RJ-45 connections on the other end, would that sort of cable work in this set up to connect multiple serial devices per port? (I'm assuming the original purpose is to connect many device console ports to one)
The WIC-1T and WIC-2T are synchronous serial cards with one and two ports, respectively.? Synchronous means that there are separate clock signals on the interface, which allows higher speeds than the usual asynchronous serial connections (even though asynchronous serial can be pretty fast nowadays).? On the cisco side, there are proprietary connectors with 60 (legacy) or 26 (smart serial) pins, but the large number of pins is owed to the fact that these ports have a number of ID pins which signal the type of cable to the cisco router, and many signals that are only used with certain physical connection types (i.e. differential signaling of X.21 and V.35).? Multiport asynchronous modules exist (e.g. HWIC-8A and HWIC-16A), but they use different connector types and cables.
X.25 does not work over asynchronous serial lines, and most standard serial ports do not support synchronous operation as they lack the required controller chips and clock signals.? SPARCstations are an exception, which is why I found myself a SPARCstation IPX.
