‘X’ Command
The ‘X’ command allows almost unlimited access to all the instrument parameters. The ‘X” command accesses the
various parameter tables in the instrument. A typical parameter table for most Marathon instruments has 240 parameters
numbered consecutively from 0 to 239 (0 – 0xEF). Instruments such as the Dualpro have many tables (0 – 31), where
each table has 11 blocks or more.
The Versapro, 10Pro-E, and Version 3.5 Carbpro have only table 0. The table value is assumed to be 0 and the
parameter is addressed directly with the possible range of 0 to 71. These number correspond with the decimal numbers
in the Versapro Memory Map table.
To READ a data value from a table / parameter number in the instrument, use the following format:
AUx (Table # Parameter #) <delimiter> <checksum> <EOT>
Here is an example of a request and response for the instrument’s proportional band setting in table 0, parameter 10
(0x0A). The instrument address is 1. The data value that is returned by the instrument is hexadecimal 0014 or 20.
