Commands Overview

All commands start with a period (.)(0x2E) followed by 2 lower case characters.

Commands should be terminated with a Carriage Return, a Linefeed or a combination of the two. All combinations are acceptable <CR>,<LF>, <CRLF> or <LFCR>.

Command echoing can be enabled with the .ec command. This is useful for testing commands with a terminal program but generally should be avoided particularly over the Bluetooth® interface where it will impact throughput.

Commands are parameterised with the parameters preceded by a minus sign (-)(0x2D)

.rd -a00000000 -bu  

Some parameter values need to be enclosed in double quotes (")(0x22).

.bt -f "1128-EU-000001"  

All parameter values are stored in the reader, if a parameter is not included the stored value will be used.

When a command uses a parameter its stored value is updated.

When the reader is powered up the stored values are loaded with defaults with the exception of the .bt command whose settings are persistent.

The parameter -x restores the stored parameters to their default values.

The parameter -n prevents the command from taking any actions, other included parameters will be stored. This allows parameters to be saved without the command being performed.

The parameter -p displays the current values of the supported parameters. Any other parameters included will be stored first.

Once the command has started (. detected) a gap of greater than 30 seconds, for the next character to arrive, will cause an error response to be sent.

Spaces (0x20) in commands are ignored unless in quotes.

The command . will repeat the last command.
