EPIM SPECIFICATIONS

A.1 EPIM SPECIFICATIONS

EPIMs enable the connection of the SEHI to the network using different media types.The SEHI100TX-22 supports the EPIM-100TX and the EPIM-100FX. This appendix provides specifications for each EPIM.

A.1.1 EPIM-100TX

The EPIM-100TX is an RJ45 connector supporting Unshielded Twisted Pair (UTP) cabling.

The slide switch on the EPIM-100TX determines the cross-over status of the cable pairs. If the switch is on the X side, the pairs are internally crossed over. If the switch is on the = side, the pairs are not internally crossed over. Figure A-1 shows the pinouts for the EPIM-100TX in both positions.
