the unit, with each packet separated by a semicolon (;) delimiter. Each data packet contains:

Two characters representing the switch designation
•
One integer describing the output channel currently connected to input channel one
•
One integer defining the board or motor address of the switch
•
Two integers defining the numbers of the first and last relay lines used by this switch (if
motor, these are 0)
•
One integer defining the number of input channels
•
One integer defining the number of output channels
LRN? Learn
Returns a string containing the commands that, if sent, reset the currently selected switch to its
current state, for example, SWITCH I J K;SRE L, where I represents the switch number, J
represents the input channel number, K represents the output channel number, and L
represents the value of the service request enable register.
