5.3.8 ENCODER OPERATION
• Input 7A & 8A are used for encoder mode. Channel A of the encoder is connected to Input 7A & Channel B is connected to Input 8A.
• When the encoder channels are correctly connected, as shown above, firmware takes care of incrementing or decrementing
the count.
• The functions that work when using encoder mode are tied to counter 7A, the on/off & reset are the only commands that work at
this time.

A. The Count and Counter Set Point are shown in the message below/Encoder
In Encoder mode, bytes 1 & 2 are the low word and bytes 3 & 4 are the high word to display a 32 bit value of the encoder count,
32 bit signed maximum positive count is 2,147,483,647.
