Example: Configuring a Single Drive Channel
The following example illustrates the sequence of commands to configure a
single drive channel with continuous drive. In the example, the operations are
directed to channel 1 on remote module 3.
The drive source must be disabled before configuring pulse or paired modes.
The channel is then un- paired and the pulse mode disabled (enables
continuous drive). Power supply recovery time and settling time
is then set to 10 ms and 12 ms, respectively. Verify is then enabled.
The switches are set to a
CLOSe default state and OCOLlector drive with an
EXTernal power supply is selected. The channel is closed. The final query of
the channel state involves querying both verified state and whether channel
drive is occurring.

being driven and a 1 if the channel is being driven.
