J2 - 9 pin (DB9) RS232 signals :

The DNA200 has a RS232 serial port interface, J2, that can connect to a terminal, printer, or video switcher. Check
your terminal, printer or video switcher manual for the correct RS232 connector type, input, output and handshaking
signal connections.

The maximum length for a RS232 cable connecting the DNA200 and other equipment is 50 feet.

A null-modem (LapLink) cable can be used to connect a DNA200 and a PC computer together if they are close
enough to each other.

If you are going to make your own cable the following is a description of the pinout of the DB9 connector on the
DNA200.
