Please note: If echo mode is active, a single <CR> forces the reader to output <CR> <CR> (echo plus
output).
3.6 Erroneous entering of commands - error codes
If a command is not entered correctly, the reader sends one of the following error codes:
Wrong command: <NAK> #00 <CR>
Wrong parameter: <NAK> #02 <CR>
3.7 Boot message
After booting the system (cold and warm start) the software version is output as described for the VER
command (see chapter 4.17), if echo is active. If echo is disabled, no boot message will appear.
3.8 Use of capital letters
The standard operating system is not case-sensitive, that means capital- and small letters are treated the
same.
3.9 Line feed
A line feed character <LF> is not sent by the decoder. If the decoder is controlled by a terminal, a line
feed can be added by the terminal software (option: replace CR by CR LF at receipt).
