AVE 2PSWT - Manual (Page 3)

INTRODUCTION
The 2PSWT is a 2 position sequencing, homing switcher. The front
panel toggle switch allows for automatic sequencing, or homing of
the 2 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
When the toggle switch is in the up position the switcher homes to
camera #1. When the toggle switch is in the down position the
switcher homes to camera #2. When the toggle switch is in the
center position the switcher sequences between the two cameras.
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 second to 60 seconds. Use a small flat
bladed screwdriver to adjust this control. Turning this pot to the right
increases the dwell time.
POWER
The switcher is powered by the included wall transformer. The unit
can be powered from 5 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 1V P-P. The output is 1V P-P and will drive
a 75 ohm load. Connect the video cameras to the switcher in the
desired order. Connect Video out to your VCR or Monitor. Plug in
the DC Coax connector. The switcher is now operational. Select the
desired front panel controls and adjust the dwell.
