5708577-A 4-3
AMN PS-2A
Note: Pins 3, 4, 6, 7, 8, 9 and 10 are open collector. Requires pull-up resistor of 10K
ohm to (+5V to +15VDC) if “high” is open or floating state.
MATCHING NETWORK INTERFACE CONNECTOR (J1)
The matching network interface connector (J1) on the rear panel of the AMN PS-2A
controller provides the communication connection to the matching network. To see
the location of the matching network interface connector (J1) on the rear panel, see
Figure 4-7 on page 4-9.
10 +LOAD LIMIT Digital output This pin is low when the positive load
limit is exceeded.
