2.2.2 SSPA COM 1 J2, SSPA COM 2 J3, SSPA COM 3 J4 Connectors
The SSPA COM 1 J2, SSPA COM 2 J3, and SSPA COM 3 J4 connectors are 19-
pin circular connectors, type MS3112E14-19S. Each serves as the primary
input/output interface between the PCCB and its specified SSPA. The typical pinout
specification is provided in Table 2-3.
Typical mating connector: ITT Cannon MS3116J14-19P
(CEFD P/N CN/MS3116J14-19P).
