EPIM-C
The EPIM-C supports thin 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 T-connector and terminator.
Figure 81 shows the setting for the terminator switch.

Connector Type

T-connectors and RG58 coaxial cable.
Grounding
The BNC port of the Coaxial Interface Modules is not connected to earth ground.

CAUTION
For safety reasons, only one end of a coaxial segment should be connected to earth
ground. Connection to earth ground at more than one point on the segment may
cause dangerous ground currents.
Internal Termination Switch
