ELECTRICAL INSTALLATION
1. General
This section gives electrical installation procedures, power distribution, and interconnect
information for each component on the TCAS 3000 system.
2. Equipment and Materials
For new TCAS 3000 installations, refer to Table 1−1 for RCZ−852 Transponder Installation Kit
information. For all other components, refer to the applicable Outline and Installation Diagram
in the MECHANICAL INSTALLATION section for mating connector part numbers.
3. Electrical Installation Procedure
The information necessary to provide the electrical interconnections is contained in the
following paragraphs. Refer to Section 4, LOADING/GRADIENT SPECIFICATIONS, for a list
of the signal names used in the interconnect diagrams and tables.

A. TCAS 3000 Computer Units
Figure 3−1 shows some general types of TCAS system installations, using various
combinations of controllers (control panels) and transponders.
The electrical installation of the TCAS Computer Units is detailed in Figure 3−2. The
various installation options require different electrical connections as described on the
interconnect diagram and the paragraphs that follow.
The TCAS Computer Unit uses programming and configuration straps to select or
deselect various TCAS functions. Refer to the notes in Figure 3−2 to determine
applicable installation wiring.
The TCAS Computer Unit ARINC 600 connector layout is shown in Figure 3−3. The
contact arrangement for the various connector plugs are shown in Figure 3−4 thru
Figure 3−8. Figure 3−9 shows the connector pin layout for the DATA LOADER connector
located on the front of the computer unit.
B. TCAS Antennas
The electrical installation for the TCAS antennas is shown in Figure 3−2. Figure 3−4
shows the TCAS computer contact arrangement for the top directional antenna and
Figure 3−5 shows the TCAS computer contact arrangement for the bottom antenna.
