VIDEO SWITCH 4 IN - 1 OUT Ref. 1038/69
The Ref. 1038/69 video switch can be used to control the auto-on
function for one main video door unit camera:
The user can select auto-on function on the “master” door unit (ID=1)
and switch onto the other cameras connected to the device by
pressing the auto-on button on the apartment station.
The device is not reset at the end of the display cycle. If a new
cycle is started, the camera following the last camera in the
previous cycle will be displayed.
In addition to the 4 control signals, the device is equipped for this
purpose with an input terminal (T) which can be connected to a button
for switching the 4 inputs in turn onto the output independently with
respect to the control signals (RE, RF, RG and RH).
The number of inputs which can be switched in turn by pressing
button T can be programmed by means of specifi c jumpers (from 2
to 4 inputs).
A jumper must be connected between RES and 0V terminals if
button T is not used.
