Mate RRCS connectors J1, J2, J3, and J4 (see
Apply firm, even pressure to the RRCS to ensure proper mating of the connectors.
RCTUA connectors are P2, P3, P4, P5. (See
RCTUBA connectors are P3, P4, P5, P6. (See
RCTUC connectors are P3, P4, P5, and P6; RCTUD connectors P5, P6, P7, P8. (See
5-35, 5-36.)
RCTUE connectors are P6, P7, and P9; RCTUF3 are P8, P9, and P10. (See
5-38.)
Note
The combined RCTUC/D and RCTUE/F common control unit can support up to 24 DTMF
receiver circuits. Both the RCTUC or RCTUE and the RCTUD or F PCBs can be equipped with
the RRCS (4, 8, or 12).
RRCSs can be installed on both the RCTUC or RCTUE and the RCTUD or RCTUF at the same
time. If only one RRCS is installed, the RRCS must be on the RCTUC. Always install the RRCS
on the RCTUC before RCTUD and the RCTUE before RCTUF.
