10.4.6 P – Set parameter
The command "P" can be used to change the value of individual parameters.
After a parameter has been successfully changed, the reader sends a
confirmation message.
Depending on the customer mode selected, the data elements parameter number and parameter value
must be interpreted differently:
In the standard ASC-I1 protocol mode the data element "Parameter value" with decimal values (00-99)
has to be used. The values for the data item "Parameter No." are hexadecimal values
For two-digit hexadecimal parameter numbers, the value parameter must always be sent in two digits
hexadecimal.
