OK (He says hopefully)

I think from reading your description, that you are looking for an adapter cable to connect a console/server switch to a PC serial port. The console/server switch side has an RJ type connector.

You already have a console/server switch to PC cable for one of two switches that is configured as RJ45 to 9-pin PC serial - Correct ?
You are searching for a console/server switch to PC cable for a second switch that is configured as RJ11 to 9 pin PC Serial - Correct ?

If so:

Please specific for each of the two switches:
Manufacturer name/ Model Number

That will at least give a start to solving the problem
Generally in my experience it is usually necessary to contact an agent or the manufacture of a device when you need a specific adapter cable.

Have you tried looking at the manufacturer's www site ? Or contacting a retailer that carries the unit concerned ?
