The MorphoAccess SIGMA Lite controller operation in the GPIO mode (general purpose input/output) is configured as follows:

  1. From the GPI 0 drop-down list (1), select the actions required for the zero general purpose input in case of an event specified in the Trigger On field (4):
    1. No Action - no action is required.
    2. Delete Template(s) - erase all biometric templates.
    3. Reboot Device - reboot the controller.
    4. Alarm - activate a sound alarm that lasts 5 seconds.
  2. From the GPI 1 drop-down list (2), select the actions required for the first general purpose input in case of an event specified in the Trigger On field (4):
    1. No Action - no action is required.
    2. Delete Template(s) - erase all biometric templates.
    3. Reboot Device - reboot the controller.
    4. Alarm - activate a sound alarm that lasts 5 seconds.
  3. In the Min. Duration (ms.) field (3), enter the time in milliseconds, after which the actions specified in the GPI 0 (1) and GPI 1 (2) fields will be activated if the relay state does not change after the corresponding signal is given.
  4. From the Trigger On drop-down list (4), select the event which triggers the actions specified in the GPI 0 (1) and GPI 1 (2) fields:
    1. Signal Falling Edge - the relay state switch from on to off.
    2. Signal Rising Edge - the relay state switch from off to on.
  5. In the GPO 0 (msec)  field (5), enter the time in milliseconds for the general purpose output, after which the output will be switched to the default state.
  6. From the Default State drop-down list (6), select the zero output default state:
    1. Low - the output relay is off. When access is allowed, the relay status will be switched to High (the "on" state).
    2. High - the output relay is on. When access is allowed, the relay status will be switched to Low (the"off" state).
  7. In the GPO 1 (msec) field (7), enter the time in milliseconds for the first general purpose output, after which the output will be switched to the default state.
  8. From the Default State drop-down list (8), select the first output default state:
    1. Low - the output relay is off. When access is allowed, the relay status will be switched to High (the"on" state).
    2. High - the output relay is on. When access is allowed, the relay status will be switched to Low (the"off" state).
  9. Click Apply (9) to apply the changes.

Configuring the MorphoAccess SIGMA Lite controller in the GPIO mode is complete.
