Operator LED

Operator Library: Hardware Platform

The LED operator provides an interface for accessing the board LEDs of the frame grabber via the applet.

Driving a logic HIGH on the input forces the correspondent board LED to light on. Driving a logic LOW on the input forces the correspondent board LED to light off.

For the exact location of board LEDs on the frame grabber, see the manual of your frame grabber.

imaFlex CXP-12 Quad: {USR1, USR2, USR3, USR4, USR5, USR6}

LightBridge VCL, mE5 marathon VCLx, and mE5 marathon VCL: {USR1, USR2}

mE5 marathon VCX-QP and mE5 marathon VF2: {USR1, USR2, USR3, USR4}

The parameter defines which of the board LEDs will be connected by the operator.

imaFlex CXP-12 Quad:

  • USR1 maps the operator to the slot LED USR1.

  • USR2 maps the operator to the slot LED USR2.

  • USR3 maps the operator to the slot LED USR3.

  • USR4 maps the operator to the slot LED USR4.

  • USR5 maps the operator to the slot LED USR5.

  • USR6 maps the operator to the slot LED USR6.

mE5 marathon VCLx, mE5 marathon VCL, LightBridge VCL:

  • USR1 maps the operator to the slot LED USR1.

  • USR2 maps the operator to the slot LED USR2.

mE5 marathon VF2:

  • USR1 maps the operator to the slot LED USR1.

  • USR2 maps the operator to the slot LED USR2.

  • USR3 maps the operator to the slot LED USR3.

  • USR4 maps the operator to the slot LED USR4.

mE5 marathon VCX-QP:

  • USR1 maps the operator to the slot LED 4.

  • USR2 maps the operator to the slot LED 3.

  • USR3 maps the operator to the slot LED 2.

  • USR4 maps the operator to the slot LED 1.

To turn the LED ON, the input I must be driven HIGH. To turn the LED OFF, the input I must be driven LOW.
