LabJack U6

The LabJackU6 USB DAQ unit has 14 single ended ADC inputs (or 7 differential inputs), twenty digital I/O inputs that can be configured as input or output, a counter, and two DAQ outputs. More product information can be found online at: https://labjack.com/products/u6.

You need the correct serial number to be able to open a port to the labjack. You can get it by clicking the ‘probe’ button in the dialog. All connected U6 labjacks will be queried and their serial numbers will be listed to the status log.

If enabled, counters use the first two digital I/O bits.

The direction of the I/O bit. Checked means it is an input bit

The values of the input bits. Blank if the bit is an output.

The values of the output bits. Blank if the bit is an input.

The ADC values. You can edit the units and specify that a channel is single ended or differential.

DAQ outputs. Note that they must be enabled to work

When displayed in an ORCA process these process limits are used for alarm limits.

When displayed in an ORCA process, the min and max values of the displayed meter need to be known.

The displayed ADC values can be scaled to represent physically meaningful numbers like Temperature or Voltage. There are internal (hardcoded) calibrations -- the values here can be used to tweak the final result.

Range selection: +/-10V, +/-1V, etc.

Channel names can be edited. Just double-click
