period = time (in milliseconds) to complete one cycle
The DC output voltage is set by the equation:
V
out
= 2.4mV*amplitude – 1.2mV*offset
The command
401,1,1024,1024,0
will output a 1.25V signal. To turn off the analog output:
401,0,0,0,0
When the analog output is off, the Vin line (pin 1) of CH4 line may be used as a
±
5 volt analog input.
Note that this is different from the other three analog input channels.
