This example is based in the LabVIEW native "NI 6584 Basic Software UART" example, however can be used until 16 Channels instead of just a single channel. The attached files were modified for 8 and 16 Channels, Half Duplex but easily can be changed for others NI 6584 types.
LabVIEW example description:
"This example implements the basic functionality of a UART. It can generate and receive data from basic UART (no flow control)."
Notice that the data length was modified to U16, because the most significant U16 represents the channels. You can change that freely.
