Type of Analog Radio Altimeter Select Straps
The TCAS processor can accept radio altitude input from digital radio altimeters and
a variety of analog radio altimeters.
a variety of analog radio altimeters.
These three straps, on RMP pins 12A, 12B, and 12C, are selectively connected to
a common on RMP-6K, to identify the type of analog radio altimeter to the TCAS
processor software. Refer to Interwiring diagram Figure 2015 for strapping details.

(d) TA/RA Display Symbol Maximum Program
These five straps, on RBP pins 8F, 8G, 8H, 8J, and 8K, are selectively connected
to a common on RBP pin 7K, to show the maximum number of intruder aircraft that
can come into view on those display units that can not display the CAS-100
maximum of 30 intruders (for example, the TA/VSI display unit).

The TCAS processor reads these straps and sends their control data to the
displays. The display unit software uses this strap controlled data to control the
maximum number of intruder symbols that can come into view on the traffic display.

(e) Ground Display Mode
This strap on RBP pin 7E controls if traffic is shown on the TCAS traffic display while
own aircraft is on-the-ground. To keep this strap input open lets traffic display
on-the-ground. Grounding this strap input prevents traffic displays on the ground
(puts TCAS in STANDBY mode). Refer to Interwiring diagram, Figure 2015 for
more details.

Display All/Threat Traffic Program
This strap on RBP pin 7F controls if all traffic is shown all the time on the TCAS
traffic display or when a TA or RA is present. To keep this strap open lets all
proximity, nonthreat, TA, and RA category traffic to be displayed at all times.
Grounding this strap input prevents the display of aircraft symbols unless a TA or
RA is present. Refer to Interwiring diagram,

(g) Functional Test Inhibit
The strap on RBP pin 8E controls if the functional test can be performed while the
aircraft is airborne. To keep this strap open lets functional test during the flight.
Grounding this pin will prevent functional test while the aircraft is off the ground.
