LabJackU3-HV
Description
This primitive allows you to control and receive data from a LabJack U3-HV data acquisition device.
Once you have the board connected to your PC you need to start the component by sending a trigger to the first input. The 'On' output will
return True if a connection has been established (False otherwise).
If you have multiple boards connected to your PC then you should provide the address of the board you want to connect to (the address is
described in the U3 user guide).
The board has 16 flexible I/O pins and 4 fixed analog inputs. These are mirrored on the component. Aside from the fixed analog inputs the
I/O can be configured in various different ways to provide analog or digital inputs. If a pin is configured as an input then it will appear as an
output connector on the component so that you can retrieve its value and if it is an output then it will appear as an input connector on the
component so that you can set its value.
Flexible I/O
To set the I/O you need to supply a comma separated string or a newline separated list of strings in a Text component to the I/O input. Each
entry defines the format for a particular I/O pin. The entry starts with two characters to determine the type and direction: "DI", "DO" or "AI" for
digital in, out and analog in respectively.
In the case of analog it defaults to single ended but you can set the negative channel with a minus symbol followed by "SE","SP","VR"
(single ended, special (0-3.6v or -10/+20v), internal voltage ref) or the number of the pin you want to have as the negative channel.
