The Model 302 will send data back continuously at the preset rate if a start scan command is sent. There
are six different types of scan, single-channel, single-channel with digital input, multi-channel, multi-channel with digital
input, multi-channel with calibration data, and multi-channel with digital input and calibration data.
For single-channel scanning, the Model 302 will take data on whatever channel was selected when the scan was started.
Channel change commands can be sent at any time during single-channel scanning. For multi-channel scanning, the Model
302 controls the channel selection. It sequentially selects the input channels and converts the data. Do not send channel
change commands during multi-channel scanning. You can send analog or digital output commands at any time during either type of scan
without altering the data acquisition timing.
