9 ELECTRICAL INTEGRATION
The following table defines the required electrical conditions:
The TRM-300 auxiliary connector contains the power supply connector (DC-jack) and the I/O connector. It is
an AVX semicustom socket connector (model 58-9157-019-000-094S) with the pin-out according to the
following table and drawing. The application mating I/O connector would be an AVX semicustom plug (or the
model 58-9157-019-000-085 SMT plug along with any standard cover 30-9157-9700-00-xxx; or the model 58-
9157-019-000-086 SMT right angle plug).
