VauxProtocol Commands & Messages (RS-232)

Connection of a computer or control system to the VC-232 serial port allows you to fully control the system using a

selection of Commands, and to obtain immediate feedback on system status by listening to Messages. This

Command/Message language is called VauxProtocol.

VauxProtocol Commands begin with an asterisk (*), followed by two letters, then one or more comma-delimited

decimal number parameters, and finally a carriage-return and/or line-feed char (CR/LF). The numbers are ascii-

encoded-decimal number strings which may range from 0 to 255. The decimal numbers may be one, two, or three

digits total, and may include leading zeroes, or not, as desired (ie: 001, 01, and 1, are all equivalent).

A comma must be used to delimit fields, and the command requires a CR, LF, or CR/LF as termination delimiter --

indicated by <cr>. Spaces may be removed, or inserted if desired (they are ignored).

Note: the following commands are all identical:

*PW,001,017 <cr>

or: * P W, 001 , 017 <cr> (extra spaces are ignored)

or: *PW,1,17 <cr> (leading zeros also optional)

Similarly, VauxProtocol Messages begin with an exclamation (!), followed by two letters, and then one or more

comma-delimited decimal number parameters, and a terminating CR/LF.
