AMX NetLinx Master-Ethernet Card/Module NXC-ME260 - Manual (Page 14)

Installation and Wiring
8 NXC-ME260 NetLinx Master-Ethernet Card/Module
Wiring length guidelines
The Master requires a 12 VDC power from a PSN to operate properly. The unit should only have
one source of incoming power.
An auxiliary 12 VDC power supply can provide power to the Master. Refer to the following table
for wiring length information:
Wiring a 2-pin power connection
To use the NetLinx 2-pin 3.5 mm mini-Phoenix power supply jack for power transfer from the PSN
power supply to the rear of the NXC-ME260, the incoming PWR and GND cables from the PSN
must be connected to its corresponding location on the 2-pin 3.5 mm mini-Phoenix connector
(FIG. 5).
Using the 4-pin mini-Phoenix connector for data and power
Connect the 4-pin 3.5 mm mini-Phoenix (female) captive-wire connector to an external Netlinx
device, as shown in FIG. 6.
Using more than one source of power to the Master can result in damage to the
internal components and a possible burn out.
