5.1.4Connecting a Thin Coaxial Segment to an EPIM-C

To connect a thin coaxial segment to an EPIM-C:

1.Set the Internal Termination Switch, located to the right of the port and labeled TERM to one of the following:

•The On position (•) if the thin coaxial segment connected directly to the port is internally terminated at the port

•The Off position (o) if the thin coaxial segment is not internally terminated at the port or externally terminated

2.If the Internal Termination switch is in the On position, connect the thin coaxial segment directly to the BNC port as shown in Figure 5-4.

3.If the Internal Termination switch is in the Off position, proceed with the following steps:

a.Attach a BNC T-connector to the BNC port on the module.

b.Attach the thin coaxial segment to one of the female connectors on the T-connector.

NOTE

Terminate each segment attached to the T-connector. If a segment is not attached to one of the female connections on the T-connector, place a terminator on that connection.

c.Attach another thin coax segment or a terminator to the other female connector on the T-connector.

For safety, ground only one end of a thin coaxial segment. Do NOT connect EPIM BNC ports to earth ground. Connecting a thin coaxial segment to earth ground at more than one point could produce dangerous ground currents.
