The MALE VOICE line (line 7) displays the Male Voice Program input status (Pin
RMP−11C). This option allows audio annunciation to be selectable for either male or
female gender. If pin RMP−11C is grounded, the male voice option is enabled (ON).
If pin RMP−11C is open, the female voice option is enabled (OFF).
The DISPLAY FLT ID line (line 8) displays the Flight ID Program input status (Pin
RMP−11B). This program allows flight identification from the transponder to be
output on traffic display busses. If pin RMP−11B is grounded, Flight ID Display is
enabled (ON). If pin RMP−11B is open, Flight ID Display is disabled (OFF).
The ADS−B SURV line (line 9) displays the ADS−B surveillance program input status
(Pin RMP−10K). This program allows the passive tracking of intruders who squitter
ADS−B squitters containing position information. If pin RMP−10K is grounded, the
ADS−B surveillance option is enabled (ON). If pin RMP−10K is open, the ADS−B
surveillance option is disabled (OFF). To activate this option, the TCAS CU must also
have hardware MOD C installed.

E. TCAS Computer Unit Self−Test
The TCAS computer unit detects system faults and displays them on its front panel
annunciators. Its flight leg memory stores system status and fault information for 10
consecutive flight legs. A flight leg is the interval between weight−off−wheels and weight−
on−wheels during which TCAS is operative. By recalling the stored data, ground
maintenance personnel can evaluate in−flight performance on the ground and fault
isolate a current or previous failure to a specific LRU or LRU interface.
Table 6−3 summarizes how the TCAS computer unit self−test is activated at power−up,
during operation, and during commanded self−test. The computer unit can activate the
commanded self−test only when the aircraft is on the ground.
