A-9: Legacy Model SX200 Connector A Pinout Diagram
CAB-200SX-01:
Connector A is a female 37-position D-sub connector that attaches to the
display unit’s male 37-position D-sub connector. Wires that are certain to be used, such
as the magnetometer connections, are pre-wired at GRT. Commonly used optional wires
are supplied loose as pre-terminated wires. Empty terminal positions are optional; for
example, Pins 10-19 are reserved for Grey code output, if your transponder requires it.
