Connecting a 10BASE2 Segment to an EPIM-C

For proper operation, the EPIM-C module to be configured for
NOTE
use in the ESXMIM module must be of EPIM board revision 05
or greater. Board revision numbers are found following the part
number printed on the Printed Circuit Board of the EPIM.
To connect a thin coaxial cable segment to an EPIM-C perform the
following steps:
Before attaching a male BNC connector to a female BNC barrel
connector or terminator, look into the end of the connector to verify that
the gold contact pin is present and centered. Any bent or broken pins may
not connect properly and should be replaced.
1. Set the Internal Termination (TERM) switch, located to the right of the
port and labeled TERM, to
a. ON position ( ) to internally terminate the thin coaxial cable
segment at the port. Thin coaxial cable segments may be directly
connected to the port.
b. OFF position ( ) to not internally terminate the thin coaxial cable
segment at the port. Segments may only be connected through
T-connectors which are connected to properly terminated
segments on both ends.
Failure to terminate each T-connector segment may result in
NOTE
improper segment operation. Place a terminator on any open
female connection on the T-connector.
