<code>mbpoll</code> commands to interact with the VFD:

<pre># monitor output frequency (displays Hz * 10)

./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 103 -t 4

+

# monitor output current (displays A * 10)

+

./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 104 -t 4

+

# monitor output power (displays kW * 10)

+

./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 106 -t 4

+
