212 – ReadInput
The table below contains the values for the following example to read the state
of an input:
$PLSC,212,1*0C
The receiver outputs a response to this command. The table below contains the
response for the above command:
For some further examples of this command:
n Read that GPIO 1 is low
Input command: $PLSC,212,1*0C
Output response: $PLSR,212,1,0*01
n Read that GPIO 1 is high
Input command: $PLSC,212,1*0C
Output response: $PLSR,212,1,1*00
n Read that GPIO 1 is not an input
Input command: $PLSC,212,1*0C
Output response: $PLSR,212,1,2*03

213 – WriteOutput
The table below contains the values for the following example to write the state
of GPIO 1 to low:
$PLSC,213,1,0*11
The receiver outputs a response to this command. The table below contains the
response for the above command:
For some further examples of this command:
n Set GPIO 1 to low
Input command: $PLSC,213,1,0*11
Output response: $PLSR,213,1*1C
n Set GPIO 1 to high
Input command: $PLSC,213,1,1*10
Output response: $PLSR,213,1*1C
n GPIO 1 is not an output
Input command: $PLSC,213,1,1*10
Output response: $PLSR,213,0*1D
