NetLinx Master Cards and Modules
Program Port Connections/Wiring
Master Cards are equipped with two Program ports. One is located on the front panel and the other
is on the rear for easy access. The port on the front panel is a DB-9 (male) connector, and the rear
port is a 5-pin (male) connector. Use a Programming cable to connect the Program port to your PC's
COM port to communicate with the Master Card. Then, you can download NetLinx programs to
the Master Card with the NetLinx Studio software program. Refer to the NetLinx Studio instruction
manual for programming instructions.
