5 Router configuration
5.1 Router level
Switches 2 - 4 on the configuration switch set the router’s level for communication with the Triton Router
Control System, and other units in the NCB system. The panels on the NCB dedicated to operate with the
router must be configured to the same level as that router.
If several routers are combined to form an audio follows video, RGB or similar system, these routers
must be configured to the same level.
The levels can be switched according to the following pattern:
- means switch down
* means switch up
Default level is 1.

5.2 Vertical interval trigger
The HDS-1602 router allows VIT switching for both SDTV and HDTV.
The HDS-1602 accepts only standard analogue black-burst/composite sync/composite video signals in
525/30, 525/29.97 or 625/25 format as the VIT reference.
In order for VIT switching of HDTV signal to work, the HDTV signal must have both the same frame-
rate and Vertical sync timing (Ov incident) as the applied VIT reference.
Since the line duration is different for the HDTV signals and the VIT reference, the actual switching time
is timed from the Ov incident.
Switch 1 and 7 on the configuration switch set the VIT mode. The modes can be switched according to
the following pattern:
- means switch down (OFF)
* means switch up (ON)
