Sync Input
There are two BNC connectors labeled "SYNC". This is a "looping" input for sync
referencing. Connect either composite sync or video with sync to either BNC. If desired,
use the second BNC to loop the signal to another device. If the loop is not used,
terminate the second BNC with 75 ohms. If no sync is available, the routing switcher will
switch at a random point rather than during the vertical interval of the reference signal.
AC Power Connections
Tahoe series routing switchers offer redundant power supplies but must be specified prior
to order. Voltage selection must be specified prior to order.
Turn on power to the frame ONLY AFTER all video and control connections have been
completed as described below.
Control Processor Dip Switch Settings
In a multi-frame system, only one processor is needed to control the entire router.
The processor module, in a Tahoe series frame, is located in the bottom PC board slot as
shown;
Your switcher has been configured at the factory for the settings you are most likely to
need. However, if you want to configure the switcher differently, you can do so by setting
the switches located on the processor board (behind the front panel). Dip Switches and
their action are given in the table that follows. Dip Switches are shown in their factory
default settings.
