AVE 8PSWT - Manual (Page 2)

INTRODUCTION
The 8PSWT is an 8 position sequencing, alarming, homing, & bypassing
switcher. The front panel toggle switches allows tor automatic sequenc­
ing, homing and by-passing of the 8 video inputs. Sequencing is con­
trolled by 2 front panel recessed dwell pots. These pots are recessed to
eliminate accidental adjustment. The dwell adjustment varies from ap­
proximately 1 second to 30 seconds. Camera position 4 & 8 are alarming.

OPERATION
The 8 toggle switches control homing, sequencing and by-passing. The
LED's above each toggle switch give a visual indication of the current
camera. Homing any camera will stop the sequence mode and display
the selected camera. If no homing switch Is used, the switcher se­
quences through all cameras selected for sequencing in the loop.
When a toggle switch is in the "BYPASS" position, the switcher will 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.
Selecting the "HOME" position will home the switcher to the selected
camera and stop sequencing.
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 approxi­
mately 1 second to 30 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 position 4 & 8 of the 8PSWT. The
alarm input is 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, this opens the clamp. Isert the wire and remove the
screwdriver blade. When an alarm is connected, the switcher will always
"HOME" to camera four on an alarm. Homing to camera four will occur
upon an alarm regardless of the switch positions of the other cameras. If
camera four is in the bypass mode, it will still home upon an alarm and
return to the sequence or other selected modes upon the completion of
the alarm. If cameras 1, 2, & 3 are sequencing, and camera 4 is In the
bypass mode, upon an alarm the switcher will home to camera four for the
alarm duration and continue the sequence from where it was when the
alarm was triggered when the alarm stops.
POWER
The switcher is powered by the included wall transformer. The unit can
be powered from 9 to 12VDC. The center post of the DC Coax is
POSITIVE.
CONNECTIONS
The VIDEO Inputs are BNC type connectors. The inputs are 75 Ohm
terminated and require IV P-P. Connect the video cameras to the
switcher in the desired order. Connect Video out to your VCR or Monitor.
Connect the Alarm if desired. Plug in the DC Coax connector. The
switcher is now operational. Select the desired front panel controls and
adjust the dwell.
