Hi,
I want to patch the rs232 cable through cat5 cabling. However the rs232 cable has 9 pins (and cat5 only has 8 pins).
Are all the pins needed for comfort, or can i miss one out?
Thanks

It depends on what it is connecting to. The UCM cable has one male and 1 female at the ends. In this cable, the connections are straight through 2-2, 3-3, 5-5. The male connector is plugged into the UCM and the female end into the PC
If you are connecting the UCM to a serial interface of another device with a connector which is the same sex as the UCM ie Female, then you need a Male to Male serial cable, and in the cable you would need to cross 2 and 3, ie 2 - 3 and 3 - 2, while 5 remains connected to 5 (common)
