These switchers can be cascaded, allowing
installation of up to eight switchers in one
1, -2, or four switchers in the
1, -2.
To cascade two or more switchers:
the operator can switch to CAMERA without
deselecting CAMERA 3. If, however, the oper-
ator wishes to switch from CAMERA 3 to
CAMERA 4, he must first deselect the
CAMERA 3 switch. In a cascading series of
switchers, the operator must deselect all lower
numbered positions to view the last position.
1. Connect video input from cameras to Inputs
l-4 on the switchers.
MAINTENANCE
2. Run a coaxial cable from the MON output
BNC on the last switcher in the series to
the EXP input BNC on the preceding switch-
er.
3. Connect each preceding switcher in the same
manner. The MON output of the first
switcher in the series connects to the
monitor. Refer to the Schematic Diagram,
Figure 5.
OPERATION
By pressing a numbered button on the front
panel, the unit displays, on the monitor, the
video scene selected by a camera at that po-
sition. To deselect it, press the button again.
This operation on a looping switcher will not
affect the scene displayed on a monitor con-
nected at another camera position.
The latching front panel switches are priority
wired, with priority on the lowest numbered
position. For example, if
the CAMERA
3
position switch is selected for monitor viewing,
