System Parameter Descriptions
This section describes the M1-Mini system parameters in detail.
13.2.1
Serial Number
The Serial Number system parameter is a read only parameter set at manufacture time. It is not a unique number
for each module. It can be set to a specific value upon request. By default, it is set to 0x00000000.
13.2.2
Firmware Version
The Firmware Version system parameter is a read-only parameter that contains a two-byte firmware version
number. The firmware version number is read with a Read System command.
13.2.3
Reader ID
The Reader ID system parameter is a read/write system parameter that contains a one-byte Reader ID value.
The Reader ID can be changed in both volatile memory (Write System command) and nonvolatile memory (Write
Memory command). The Reader ID can be read out of either volatile (Read System command) or non-volatile memory
(Read Memory command). All non-volatile writes have to be followed by a power cycle before the settings take
effect. Reader ID values can take on any value from 0x00-0xFF. 0xFF is the default and the reader responds to
commands sent to it not containing the Reader ID. From this point forward examples some examples are in ASCII
mode and some are in binary mode.
13.2.4
Baud Rate
The Baud Rate system parameter controls the baud rate for serial data communication. The TTL serial interface. The
following table contains the possible values for the data field.
