NOTE
The Model 7709 is shipped with plastic connector covers installed on the D-shell connectors. Each
cover is secured to the connector by two screws. After removing a connector cover, retain it and
the screws for future use. Any unused D-shell connector must have the connector cover installed.
The Model 7709 is supplied with one 50-pin male IDC ribbon cable connector, and one 25-pin male IDC ribbon cable
connector. These ribbon cable connectors mate to the D-shell connectors of the switching module.
WARNING
When using IDC ribbon cable connections, DO NOT exceed 42V anywhere in the test
system or at the front panel inputs of the Mo
del 27xx. For higher voltage applications,
use larger wire (up to #20 AWG) and solder cup D-shell con
nectors.
