Each programming mode has an associated programming
worksheet (see Appendix A) that details the structure of each
programming mode, mapping out how to identify and change
each of the parameter values within the specific programming
mode.
In most parameter programming situations, only one or two
parameters in a specific programming mode will need to be
changed. To make this task easier, most programming modes
contain shortcuts that allow specific parameters to be changed
without having to flow through all the parameters in a
programming mode. These shortcuts are depicted in the
programming worksheets with an alpha character in a box just
left of the parameter name. Scanning the corresponding alpha
Hex tag provides a shortcut to that specific parameter.
Some programming parameters require byte data to be
entered. Use the ASCII Code Chart for the appropriate data.
