50-Pin D-Sub
Male Connector
WARNING::
As a safety
feature, interlock pins (17 and
33) must be shorted to enable
the analog bus relays, which
are on Matrix 2, to close. The
optional 34933T-002 (for
1-wire) terminal block shorts
these pins for you. This safety
feature protects inadvertent
routing of high voltages from
the analog buses to the D-sub
connector of the module.
