LASSEN SERIES 16 & 32 HD/SDI

Sync Connector
There are two BNC connectors labeled "VID. REF IN". This is a "looping" input for sync
referencing. Connect either composite sync, video with sync, or Tri-level 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.
J1 Connector
The connector labeled J1 on the back panel is used to connect other devices to the router.
Contact the factory for correct configuration before connecting other devices.
AC Power Connections
Some SVS routing switchers offer redundant power supplies but must be specified prior to order.
The power supplies are universal AC inputs. Voltage selection is not necessary because the
power supply senses the correct AC input automatically.
The HD/SDI models use a power switch located on the rear of the frame. Turn on power to the
frame ONLY AFTER all video and control connections have been completed as described below.
Control Processor Dip Switch Settings
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.
OFF
S1
ON
0 1
Note:
Changing any Dip Switch causes an automatic reset after a few seconds.
Force router reinitialization to empty configuration settings:
0= Normal, 1= reinitialize
Software download:
0= normal operation, 1= download new software and
burn flash
Force crosspoint initialization:
0= restore previous xpoints, 1= set xpoints to 1-1, 2-2, etc
.
For router status, send:
0= an X cmd for each level, 1= mix Y, X, or V (use shortest)
