2.2.4 “RF INPUT SWITCH | J6” Connector
The PCCB contains a built‐in selector switch – a latching 28 VDC coaxial unit. The
switch position is selected by the 6‐pin circular “RF INPUT SWITCH | J6”
connector (CEFD P/N CN/MS‐PT07M6PC).
Mating connector: ITT Cannon MS3116J10‐6S (CEFD P/N CN/MS3116J10‐6S)

2.3 RF Interface Connectors
2.3.1 “RF IN 1 | J7”, “RF IN 2 | J8” Connectors
The Type ‘N’ “RF IN 1 | J7” and “RF IN 2 | J8” connectors serve as RF signal
input interfaces to the PCCB. Note that:
• The PCCB selects the “RF IN 1 | J7” input when the “RF INPUT
SWITCH | J6” ‘POS1’ Signal Function is activated.
• The PCCB selects the “RF IN 2 | J8” input when the “RF INPUT
SWITCH | J6” ‘POS2’ Signal Function is activated.
2.3.2 “SSPA OUT 1 | J9” Connector
The Type ‘N’ “SSPA OUT | J9” connector, located on the left side panel of the
PCCB, provides the RF signal output from the PCCB to SSPA #1.
