Virtual Port Group Function
The U2600A Series USB isolated DIO modules allow you to randomly select any
eight input bits or output bits and group them into one channel as a virtual DIO
port. You must select exactly eight bits to group them to a virtual channel.
However, only input bits canbe grouped with input bits and output bits with
output bits. Therefore, the input bits should not be grouped with the output bits.
For input operations, the channel number is 199 and for output operations, the
channel number is 299. The grouping does not need to be sequential in nature,
since the bits in channel 199 or 299 will link the specified bits to its reference
points.
The following shows the examples of SCPI commands on how to group the input
bits in channel number 199 and output bits in channel number 299.
SCPI Example 1, Grouping the input bits
NOTE
You must select exactly eight input bits and group them into virtual channel 199
or exactly eight output bits and group them into channel 299.
