Chapter 6: Connector Pin Assignments
Relay outputs are connected to the board via a 50-pin HEADER type connector named P3. The mating
connector is an IDC type with 0.1 inch centers or equivalent. The wiring may be directly from the signal
sources or may be on ribbon cable from screw terminal accessory boards such as the STA-50.
