with CSDB Code Selection and Dual Antenna Operation
(a) Figure 18/GRAPHIC 34-50-96-99B-085-A01 shows a TDR 94D in a TCAS
install
ation with a CSDB control and dual antennas. If the transponder is operated
with only a single antenna, a special strap is r equired. The diagram also shows a
CADC for altitude data. This can be an encoder as shown in Figure 16/GRAPHIC
34-50-
96-99B-083-A01. Either way, appropriate strapping is required. The
CTL-92T, a requirement for TCAS control, is connected between the TDR-94D and
the CTL-92/92A. In this installation, transponder control data is entered on the
CTL-9
2/92A, and the T CAS control data is added to the data word in the CTL-92T.
