Control Method C: Dry Contact
Pg 14Installation / Step 4 / Control / Dry Contact
This method of control is for use with momentary
contact switches, such as a push button switch, or
relays, commonly found in control systems. It requires
hard wiring from the point of control to the Connect.
Momentarily shorting the appropriate leads either
sends the screen down to the lower limit or up to the
fully rolled-up position. No current or extra power
supply is needed to operate the screen.
Power should not be applied to the dry contact
connections. Doing so may damage the Connect and
void the warranty.
To send the screen DOWN, momentarily connect the
wires to pins 3 and 4. The Connect power LED will go
dark during RF transmission and the screen will unroll
to the lower limit.
Control Method B: 12VDC Trigger
Installation / Step 4 / Control / 12VDC Trigger Pg 13
A DC trigger voltage will cause the Connect to send
RF commands to the screen to operate it. This wiring
method is usually used to allow the projector to
directly control the screen. When a projector with a
trigger output is turned on, it sends out a constant
voltage that may be used to deploy the screen. This
method requires hard wiring between the point of
control and Connect.
With the Connect, a constantly applied DC voltage in
the range of 5V – 12V will send a wireless command
to deploy the screen to the lower limit. The screen
will stay in that position until the voltage is removed.
Removing the trigger voltage sends a wireless
command to roll-up the screen.
The center pin is positive and the outer contact (barrel)
is negative.
