I have a female RS-232 cable connected to my MSC-400.

I'd like to connect my PC to the other end (ie. a male-male cable).

How should I wire the cable? Should it be a null-modem cable?

 your PC should have a female jack on it if you are using a built in com port. In which case a female URC cable will plug right in.  If you need to extend it, the cable should be straight thru. (pin 2 to 2, pin 3 to 3, pin 5 to 5)

if you are using a USB to serial adapter on the PC that accepts a male connection instead of female, then you will probably have to make a crossover   pin 2 to 3, pin 3 to 2, pin 5 to 5.
