Figure 6−7. Typical Program Pins 2/3 Page
Programming pins on the TCAS computer associated with each of the functions
defined on the Program Pins 2/3 page are listed below. Where more than one
program pin is indicated, the listed connector pins correspond to the display digits
read from left to right. A one (1) indicates the associated pin is grounded. A zero (0)
indicates open.
BCA EFIS 0 RA/TA block transfer program that determines the type of
data transfer from the TCAS CU to the TA/RA displays:
A (1) indicates ACSS BCA EFIS format. A (0) indicates
ARINC 735 format: RMP−12C.
CABLE DELAY
PROG
000 RF delay compensation program for antenna cable length
difference (top versus bottom): RBP−7G, RBP−7H, RBP−7J
TEST MODE 0000 Shop test function (all 0s for flight mode):
RBP−9D, RBP−9E, RBP−9F, RBP−9G
FUNCT TEST INH 0 Inhibits cockpit self−test when airborne (0 for no inhibit):
RBP−8E
SIM SOFT ENABLE 0 Simulator Software Enable input: RBP−10K
Should always be (0) for flight mode
MAX # INTRUDER 00000 Select maximum number of traffic symbols displayed on VSI.
Value for each digit, from left to right, is 16, 8, 4, 2, 1. The
maximum number is the sum of not selected values (0s):
RBP−8F, RBP−8G, RBP−8H, RBP−8J, RBP−8K.
