EPIM SPECIFICATIONS
SEH USER’S GUIDE A-5
A.1.4 EPIM-C
The EPIM-C supports thin-net 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 tee-connector and terminator.
Figure A-4 shows the settings for the terminator switch.

ground currents.
