4.2 The VP-128H Without the Front Panel (but with the Rear Panel) You can configure and operate the VP-128H without a front panel when operating the VP-128H via a remote panel, RS-232 control, or 10 Base T control. 1 These buttons operate in the ‘one out of n’ mode. When one of these buttons is pressed the previous button is cleared and
the new selection is latched and tallied. If the selected output i s ‘locked’ the lamp in the output button flashes and the correct
input status is tallied via the input select buttons
2 Each output can be muted in dependently; and can be set to a delayed switch through black, with a user selectable delay
increment for each output
3 These buttons operate in the ‘one out of n’ mode. When one of these buttons is pressed the previous button is cleared and
the new selection is latched and tallied. When an output is selected the current state of the corresponding input is tallied in the
appropriate button. If the source is a breakaway, a flashing lamp indicates the audio selection. If the output being controlled is
locked, pressing the input select button has no affect
4 If the power supply needs to be replaced, you can access it from the front after removing the front panel (see section 4.3).
There is no harm leaving the power turned ON continuously, or in using the AC cord as the ON/OFF switch
5 With an HD15-to-BNC breakout, these two SYNC BNC connectors can be connected in a looping manner to a VP-128H
input or output. Inside the VP-128H, the BNC connectors connect to a sync separator circuit, which separates vertical sync
from composite video, composite sync, po sitive V pulse or negative V pulse. If left unconnected, the VP-128H operation is
not adversely affected. If two or more of the VP-128H inputs are already synchronized to each other, con nect the BNC
connectors. By using the same reference to the cameras and to the VP-128H, a much cleaner switch will occur because it will
happen in the vertical interval
