The following figure shows the pin-out of the mating female Hirose NX30TA-15PAA connector to
which the network wiring or transceiver pod is connected. The Hirose connector plug should be
protected with a cover (Hirose NX-15T-CV1).
The following figure shows a block diagram of the electrical interface of the 15-pin network port.
The R1 resistors used in the PCC-10 card buffer the CPx lines to and from the Neuron ® 3150 ® Chip,
and have a value of 82Ω ±5%. Examples of how to interface the PCC-10 card to external transceivers
can be found in Appendix A, External Transceivers. The following table describes the functions of the
card’s network port.
