Cabling Examples

The DSU/CSU is supplied with an AC power module. You must provide the DTE and
network cables.
Optional cables that you can order from the company are described in Pin Assignments
in the Operator's Guide.
NOTE:
The 120 /75 switch selects either the 120-ohm balanced network interface or the
75-ohm unbalanced network interface. The RX SHIELD switch selects either an
"open" or "earth" shield connection for the 75-ohm RX interface. (This switch must
be set to "open" when using the 120-ohm interface.)
