2.3.4 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 2-6 shows the setting for the
terminator switch.

Connector Type
BNC receptacle, with gold center contact, for use with BNC type tee-
connectors and RG-58 thin-net cable.
Grounding
For safety, only one end of a thin-net segment should be connected to
earth ground. Connection to earth ground at more than one point on
the segment may cause dangerous ground currents.
The BNC port of the Coaxial Interface Modules is not connected to
earth ground.
Internal Termination Switch
= On (internally terminated)
= Off (need external termination)
