INTERFACES:_______________________________

Antenna

This BNC connector is for connection only to the provided antenna directly

or via a 50 Ohm remote antenna cable.

Connector J1-1, 2, 3

This set of pins is used for serial communication with the ProComm.

They are used for factory programming and should not be connected

during normal operation. Pins J1-2 and J1-3 are used to change the

radio channel selected. See the Configuration section for the details

of radio channel selection.

J1-1 Factory programming initiation signal.

J1-2 Factory programming transmit signal.

J1-3 Factory programming receive signal.

Connector J1-4, 5

This pair of pins provides access to an analog output that can be

used for speed control, chart recording, comparitor thresholds, or

other types of analog control signal. The actual operation of this

output must be specified by the customer for factory programming.

J1-4 Digital to analog output signal. Provides 0-10VDC at a

maximum of 30mA DC.

J1-5 Ground reference and shield for J1-4 (and all ProComm

circuitry). Cabling to this pin must be routed away from

noise sources.

Connector J2-1, 2, 3, 4

This set of pins provide two discrete AC inputs to the ProComm. A

120V AC nominal input applied between J2-1 and J2-2 will be

indicated as input A. A 120V AC nominal input applied between J2-3

and J2-4 will be indicated as input B.
