EPIM-C
The EPIM-C supports thin-net coaxial cabling and is equipped with an internal
Cabletron Systems TMS-3™ Transceiver. You can use the TERM switch on the
front of the EPIM-C to set the internal 50-ohm terminator. This eliminates the
need to connect the port to a tee-connector and terminator. Figure A-5 shows the
setting for the terminator switch.
