EPIM INFORMATION
A.1 EPIM SPECIFICATIONS
EPIMs enable the connection of the SEH to the network using different media types.The SEHI100TX-22 supports the EPIM-100TX, EPIM-100FX, and the EPIM-100FMB. This appendix provides the 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 crossover 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.
Position X (crossed over)
1. RX+ | 5. NC |
2. RX- | 6. TX- |
3. TX+ | 7. NC |
4. NC | 8. NC |
