CONTROLER OPTIONS (CONTINUED)
5. RF (radio frequency) Control
An optionally available RF module will plug directly into the RJ control port on the IMC control board
The motors will then be controlled via small hand held RF transmitter The transmitter contains a small
electronic battery that will require future replacement RF control can be used in conjunction with LV
switch terminals to allow “selective switching”
6. Serial Connectivity – IBT 100 Serial Converter
By using the optional IBT-100 Serial Converter, the system can be controlled via RS-232 serial com-
mands In this fashion, the serial commands will duplicate the same functionality as the dedicated 5
button wall keypad Use a dual RJ-25 4 conductor patch cable to connect the IBT-100 to Port “O” of
the screen board The IBT-100 can now be connected to your computer or other serial device via the
standard DB-9 connector
OPERATING THE GEMINI DUAL IMC CONTROLLER
Plug in the main AC power cord or activate the circuit breaker to “on” The control boards are now
active and ready for use Pressing Channel A on the wall switch in the “down” mode will deploy the first
screen The screen will automatically stop at its motor’s deployment setting Or, you can stop the mo-
tor by pressing the red “Stop” button Pressing the Channel A wall switch to the “Up” mode will retract
the screen Once the first screen is retracted, press Channel B “Down” to deploy the second screen
During first time deployment it is advisable to slowly and incrementally lower the screen Use the stop
function repeatedly While doing this, visually inspect the screen as it deploys making sure it does not
get restricted in any manner Once the screen has fully deployed and stopped, normal operation can
resume
If the trigger wire has been connected, the projector will activate the motors to deploy when it is ener-
gized Conversely, when the projector (trigger) is switched off, the motors will retract When using this
trigger feature,
never
suddenly reverse the direction of the motors while they are operating Exercise
patience to allow the motors to fully cycle and stop before changing directions
