D. VSI/TRA Displays
Table 3−4 and Table 3−5 contain the interface information for the various ACSS VSI/TRA
displays. Table 3−4 contains interconnect data for the 41−pin connector units. Table 3−5
contains the interconnect data for the 55−pin connector (bootstrap) units.
Figure 3−10 and Figure 3−11 show the connector pin layouts for the VSI/TRA.
Figure 3−10 shows the 41−pin connector configuration and Figure 3−11 shows the 55−pin
connector configuration.
