INTRODUCTION
The 8PSWT is an 8 position sequencing, alarming, bypassing, and homing
switcher. The front panel toggle switch allows for automatic sequencing,
homing, and by-passing of the 8 video inputs. Sequencing is controlled by a
front panel recessed dwell pot. This pot is recessed to eliminate accidental
adjustment. The dwell adjustment varies from approximately .2 second to 60
seconds.
OPERATION
The 8 toggle switches control homing, sequencing and by-passing. The
LEDs above each toggle switch give a visual indication of the current cam-

selected camera. If no homing switch is used, the switcher sequences
through all cameras selected for sequencing in the loop.When a toggle
switch is in the “BYPASS” position, the switcher willl drop this camera from
the sequence or bypass it. When the toggle switch is in the “SEQUENCE”
position this camera is included in the sequence.
DWELL
The dwell or time
that each camera
appears on-screen
can be adjusted by
the recessed front
panel control. This can be varied from approximately .2 seconds to 60
seconds. Use a small flat bladed screwdriver to adjust this control. Turning
this pot to the right increases the dwell time.
ALARMING
The alarming feature is tied to camera positions 4 and 8 of the 8PSWT. The
alarm inputs are located on the rear of the switcher. This compression type
connector allows for the connection of an alarm switch or other alarming
device. To open the cage clamp, insert a small, flat bladed screwdriver
in the small slot below the clamp. When inserted, push the screwdriver
slightly downwards to open the clamp. Now insert the wire and remove the
screwdriver blade. When an alarm is connected, the switcher will always
