connections. This connector provides 28 VDC, 12 VDC battery holdup,
left/right audio output, data bus control, data bus shield, infrared input,
four (4) strapping pins for alternate configuration of infrared digital
command codes, and antenna high and shield. Refer to Section 2.8 for
connector/unit connector information.
2.6.2 The RCP-021-40x utilizes one 15-pin connector with a flying lead BNC
connector. This 15-pin connector provides 28 VDC, left/right audio
