This section describes the input adapters available to connect typical
telecommunications signals to the rear panel of the SSU-2000 and SDU-2000.
Input Adapter Panel for 1-Port Input Module
Symmetricom offers three Input Adapter panels for use with 1-port Input modules.
Each panel has the following common features:
Accommodates up to four separate input signals
Switch-selected inputs allow for DE9 and another connector type
Switchable input termination impedance
Switch-selected link between signal and frame ground (when a frame ground is
connected to the lug on the rear panel)
1-m SCSI connection cable is included with the Adapter
The Input Adapter (part number 22013069-001-0) used with a 1-Port Input module
is shown in Figure 7-9. Each port has a switch-selected BNC and a DE9 connector,
and the input termination impedance is switch-selectable between 50, 75, 100, 120,
or 2.2 kΩ.
