RBP-8E
Self-Test Test Inhibit Program Pin (NO)
This program pin determines if self-test will be inhibited while airborne. If grounded,
this pin inhibits self-test while airborne. If open, self-test is enabled while airborne.
RBP-8F
TA/RA Display Symbol Maximum 16 Program Pin (NO)
The T
3
CAS computer unit establishes the number of intruder symbols to be
displayed on the TA display through the program pins RBP-8F, -8G, -8H, -8J, and -
8K. This number can vary between 0 and 31, depending on the programming that
is a summation of the selected pins (-8F = 16, -8G = 8, -8H = 4, -8J = 2 and -8K =
1). Connecting one of these pins to program common (RBP-7K) conveys that the
associated pin is not selected and that its value is not included in the summation.
Leaving the pin open conveys that the associated pin is selected and its value is
included in the summation. The encoded number is placed within the RTS data
word (label 357) and sent to the display. The display should then limit the intruder
symbols to this number. NOTE: Although it is possible to program pin the
maximum number of intruder symbols to be displayed to be less than 8, T
3
CAS will
output a minimum of 8 intruder symbols to the display.
