Program Port Connections and Wiring
The Integrated Controllers are equipped with a Program port located on the front of the unit. Use an RS-232 programming cable to
establish a connection between this Program port to your PC's COM port. The connection provides communication with the NetLinx
Integrated Controller. With the connection established, you can download NetLinx programs to this on-board Master using NetLinx
Studio software available at www.amx.com.
Refer to the
NetLinx Studio
instruction manual for programming instructions. The following table shows the rear panel Program
Port connector (male), pinouts, and signals.
NOTE:
When wiring the 422/485 connections, do NOT use pre-made 9-wire cable or connect the wire in the cable to any connection
that will not be used by the DB9 serial port. Only use wiring that connects the needed pins.
