WinDaq software:
If any synced device has two or more enabled analog channels, all
synced devices must enable the same number of analog and digital
channels and the same sample throughput rate. If all synced devices
have one or zero enabled analog channels, sample rate per channel
must be the same across all devices.
Programmed (.Net- or protocol-based): Sample rate per channel must be the same across all synced
devices.
*One or more digital ports configured as a discrete input counts as one digital channel. Rate and count inputs count
as one digital channel each.
