Does the matrix require a null-modem (crossover) serial cable or a straight through cable?

The answer is null-modem, or crossover cable. Pins 2 and 3 are crossed and 5 is ground. It was originally designed this way so you could easily disconnect the serial cable that goes from the matrix to your control system, and plug it directly into your computer for troubleshooting or setup purposes.
