Optical Keyboard

The keyboard uses an Infrared link to communicate with the GT1 control panel. It is used only for service programs and can not be used in place of the virtual keyboard of the control panel. The keyboard must always face the control panel when in use and must be less than 1 meter away from the control panel (IR). The keyboard uses 4 AA batteries as an internal power supply.

CAUTION: Old batteries can leak and damage the keyboard. Always keep fresh batteries in the keyboard (or remove when not in use).

If more than one GT1 is in use in the workshop, the optical keyboard should be configured to a specific GT1 control panel as follows:

  1. Press and hold the identification key while pointing the keyboard at the control panel.
  2. Press a numeric key, 0-7 on the keyboard. The control panel will now respond only to commands from that keyboard.

If necessary the identification can be changed at anytime following the above instructions.
