Manual ARE i2.0x LF release V2
2.3 Firmware ARE i2.0x LF
ARE i2.0x LF works with (all) low frequency transponders in ASK, PSK and FSK modulation. Please see chapter 2.3.15 for
details on which transponder chips are implemented. Depending on the selected algorithms, not all instructions below make
sense so only those which do work accordingly (e.g. write command 'wd' does not work for a read only transponder).
2.3.1 Instruction Set
Communication with ARE i2.0x is based on a simple ASCII text based protocol. The host sends text based telegrams to ARE
i2.0x and receives text based telegrams back containing the answer to the query. Communication to ARE i2.0x is always
triggered by the host.
2.3.2 General format of instruction set
The protocol format is as follows
Instruction <CR> for instructions without parameter
Instruction <SP> parameter <CR> for instructions with only 1 parameter
Instruction <SP> parameter <SP>data<CR> for instructions with parameter and data
The space character <SP> separates commands from parameters and data and the <CR> character acts as command line
terminator.
instruction<CR> can be used to check the current parameter value for instructions that carry a parameter.
Input Instruction <CR>
2.3.3 BD
BD – Baudrate parameter sets the baudrate for ARE i2.0x. Please Note: Standard parameter is 38.400 baud.
