B.5 EPIM-C
The EPIM-C supports thin coaxial cabling and is equipped with an
internal Cabletron Systems TMS-3 Transceiver. 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 T-connector and terminator.
Figure B-1 shows the setting for the terminator switch.
