PRC-25 & PRC-77 Test Adapter

Front	Back

Description

This test adatper connects to the "POWER" connector on the PRC-25, PRC-77, X-mode on the VRC-12 series radios and the Tx/Rx & REMOTE  MSC-2001 plus other things.  It has 12 each spring clip binding posts that connect to the corresponding contacts.  The male connector that mates to the radio is marked 9215 ACCPW06B12-14P and has 14 Pins.  The female connector, like the one on the radio is marked 30194 GC01A12-14S and has 14 sockets.

Pins K and N have no wire connected.

The following terminals are present:
 

Pin Letter	Test Box Label	PRC-25 Function	PRC-77 Function	MSC-2001 Rx/Tx	MSC-2001 Remote	Binding Post color
A	GND	Ground	Ground	Gnd	Gnd	Black

F	+13V	Battery +13 VDC	Battery +13 VDC	Battery +13 VDC	Battery +13 VDC	Red

N	na	+13 from FUNCTION sw		+13 from VEU	+13 Into VEU	no binding post no wire
P	OUT SHUNT	na	Wideband audio out			Silver
R	TR	na	wideband audio in			Silver

The binding posts carrying DC power have Red Caps.  Ground is black and the rest are just the raw Silver.  If the radio jumper cap is placed on the female cable end then the test adapter acts as taps into the lines.  If the jumper cap is not installed then the radio needs to be powered through the test adapter.

It's strange that pins K and N are not part of the test adapter.  If you know why let me know.
