5.3. Vertical interval trigger
The NTW-VD3232 router provides vertical interval switching. If vertical interval switching is desired you have to connect an
analog VIT reference signal to the VIT input. The NTW-VD3232 provides a looped VIT input. Please terminate the loop
with 75 Ohms if loop output not in use.
Switch 7 on the configuration switch SW A enables or disables the VIT sensing on the VIT input. If VIT switching is enabled
but a proper signal is missing, the router will automatically switch without VIT.
The VIT can be switched according to the following pattern:
- means switch down
* means switch up
Switch 7 VIT
- disabled
* enabled
Default is VIT enabled.
5.4. Power up mode
Switch 8 on the configuration switch SW A defines the power up mode. The NTW-VD3232 router provides two modes for
powering up the system.
Mode 1 switches all outputs to input 1.
Mode 2 switches all outputs according to the buffered information in the routers processor system.
The power up reset can be switched according to the following pattern:
- means switch down
* means switch up
Switch 8 Power Up Reset
- Mode 2
* Mode 1
Default is Mode 2.
