The Input Adapter (part number 22013066-002-0) has a switch-selected Siemens
1.6/5.6 mm connector and a DE9 connector; the input termination impedance is
switch-selectable between 50, 75, 100, 120, or 2.2 kΩ.
The Input Adapter (part number 22013066-003-0) has a switch-selected Siemens
1.0/2.3 mm connector and a DE9 connector; the input termination impedance is
switch-selectable between 50, 75, 100, 120, or 2.2 kΩ.
The rear panel of the Input adapter contains three SCSI-II type connectors that
connect to each Input module connection on the rear panel of the shelf via a
supplied 1-m input cable. A frame ground lug is supplied to connect a frame ground
connection.
The pinout for the DB9 connector is listed in Table 7-14.
