LEDs and Signals

Last modified: Thu Feb 15 18:56:29 2001

The MOBOTIX M1 Camera has six LEDs on its frontside to signal different system states. Using the page LEDs and Signals you can turn them off or change their meaning.

LED Signals

Each LED can be assigned to a signal function. The signals are:

Signal	Meaning
off	The LED is always dark, it will not be turned on while the camera is running in its regular mode. (Note it will be turned on if the camera reboots.)
on	The LED is always highlighted.
blink	The LED is slow blinking.
flicker	LED is fast blinking.
Event	The LED is turned off, but any application may use it to signal its state (e.g. Event Control).
PIR	The LED will signal any motion detected by the Passive InfraRed (PIR) motion detector in the middle of the camera. The sensitivity can be changed in this menu too (currently not supported).
Ethernet	The LED signals any data traffic on the ethernet interface.
ISDN	The LED signals any traffic on the ISDN bus. It also signals incoming calls on the bus nevertheless they are not accepted by the camera.
Serial	The LED signals any outgoing or incoming data on the serial line.
Camera	On LED 1 and 5 the image exposure time for the right and left camera can be signaled.
System	System state can be assigned to all LEDs at once. The result will be different factory states for every LED.
Left Key	The LED will highlight, when the left key (view direction of the camera) is pressed.
Right Key	The LED will highlight if the right key (view direction of the camera) is pressed.
Signal Input	The LED will highlight if the signal input (Pin 9 to 5) is closed.
Signal Output	The LED will highlight (for control) if the signal output is switched low (Pin 1 to 5).
Microphone	The LED will highlight if a given level of noise is reached. The threshold can be set in this menu too.
IR Remote Control	The LED will highlight if a InfraRed Signal of a remote control box is detected.

The LEDs can be set one by one or all at once by the selection all LEDs.

Control Levels

For the PIR (Passive InfraRed Motion Detector) and the microphone the threshold can be be defined in the range from 0 to 100%. The event will be triggered, if the signals threshold is skipped.

Note: The microphone is not supported in the current software release.

Serial Setting

Within the menu LEDs and Signals you can control the Serial Output Switch (Pin 1 to 5). By selecting on the output will be switched to ground (Pin 5) with max. current of 50 mA. Off will set output to open state.

You can test the setting of the serial output by setting some LEDs to Signal Output.

Current Sensor Values

The page LEDs and Signals displays also current values of some sensors of the camera.
