Program Port Connections/Wiring
The NXC-ME260/64 is 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 an RS232 (male) connector and the rear port is a grey 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 using the NetLinx Studio 2 software 
program. 
Wiring a power connection
Use a 12 VDC-compliant power supply to provide power to the Master through 
the rear 2-pin 3.5 mm mini-Phoenix. Use the power requirements information  
listed in the Specifications table to determine the power draw. The incoming 
PWR and GND cable from the PSN power supply must be connected to their 
corresponding locations within the PWR connector. Refer to the unit’s 
instruction manual for more detailed wiring connection information.
