(2) RCZ852 Diversity Mode S Transponder
Table 38 contains the interconnect data for the RCZ852 Diversity Mode S
Transponder, Part No. 7510700850/951.
Prior to final installation of the transponder mounting tray, the strap assembly,
Figure 312, located on the back of each mounting tray must be programmed to
incorporate the aircraft Mode S address and the desired options. Information for
programming the strap assembly is contained in Table 39 and Table 310.
Programming of the strap assembly consists of removing or installing a string of
jumper wires that provide a 48bit serial data word for encoding the system
configuration. In Table 310, the output is grounded if the corresponding W* (jumper
wire) is installed for a particular bit, and open if the jumper wire is cut out.
The strap assembly is shipped with all 48bit jumpers installed. If a jumper is
inadvertently cut out or a parameter change requires a jumper to be reinstalled, a
suitable piece of AWG 24 bus wire should be used.
