Designation PCB Pin Count Connector Type #
J3 "Ext Rcvr" 8 Phoenix Header 6
The J3 connector is allocated to support various types of receivers.
The flexible I/O includes:
1) +5 and +24 VDC for powering a receiver
2) a discrete lock input
3) 12 bit resolution analog to digital input for measuring signal strength over a +/- 10 VDC range
4) an RS-232 serial channel for control and monitoring
5) a "loop out" of GPS data to provide lat/lon/time data
How the J3 I/O is used is determined by which "Receiver 1" software option is present (see 3.1.5).
If there is no integrated receiver support (Receiver 1 option "N"), then the use of the analog signal
strength input and the discrete lock input may be programmed from the "SS1 Signal Strength Factors"
configuration screen (3.3.1.2.7).
If there is software support for a particular receiver present, then the use of J3 I/O will be unique to that
receiver and will be detailed in an appendix describing that software option.
