4.7 TRC899/WX-1000 ADAPTER PLUG
An adapter plug can be used to by-pass SKY899 only if a WX-1000 Stormscope system is installed. The
adapter will permit continued operation of the WX-1000 if the TRC899 is removed for service. It can also
be used as a troubleshooting tool when attempting to isolate a problem to either or both systems.
The adapter plug mates with P1. It can be purchased from BFGoodrich Avionics Systems (P/N 805-11910-
001) or fabricated locally from the details provided in figure 4-4.
