b. That all RITs have the proper setting (c/d, e/f).
c. That all cabling is routed and connected
Any deviations from the proper settings and connections may result in error
messages being displayed on the MCS. FFCS and RIT settings are not operator
level tasks and are covered in TM 11-5830-263-20&P. Refer to higher level
maintenance for the proper FFCS and RIT settings or if error messages are
2.10.1. Initial Programming
of the MCS
To initially program the MCS we are looking at a system containing 1 MCS, 4
FFCSs, and 1 RIT. MOSs and Loudspeakers do not register on the MCS and
therefore do not require programming. For the programming procedures
described below the following parameters are defined:
FFCS 1, Radio A, Receive only
FFCS 2, Radio A, Receive and Transmit
FFCS 3, Radio A and B, Receive and Transmit
FFCS 4, Radio A and C, Receive and Transmit
a. SETTING THE SYSTEM CONFIGURATION
1. On the MCS, set and hold the PROGRAM switch in the STORE position.
2. While holding the PROGRAM switch in the STORE position depress and
hold the CHANGE button.
3. While holding the PROGRAM switch in the STORE position and
depressing the CHANGE button, set the SYSTEM switch in the ALL position.
Observe the display as it cycles through * * * * , P r 1 5 ,
v 0 7 and c f i g . When c f i g appears on the display
release the PROGRAM switch and CHANGE button.
To learn the configuration of the system the
SYSTEM switch can also be placed on PROG 1,
PROG 2, or PROG 3, while doing the System
Configuration procedures. On vehicles which do
not have a ring configuration, but rather a two
branch, the system configuration procedures
prevent the "ru" error message from appearing.
The display will then show the system configuration, e.g. what FFCSs (1,2,
3,4,5,6) and RITs (c/d, e/f) are connected as well as if the ring is connected.
