Startup Command

The M1-Mini has a provision to store a single command that is executed upon power up. This command is stored by

writing to the Startup Command system parameter using the Write System command. The M1-Mini executes the

command upon power up and sends the response in either Binary or ASCII mode depending on the mode in which

the command was stored.

The entire command must be stored—all the fields relevant to the command must be present. For example if the

CRC, TID and/or RID flags are set, then the respective fields must have the correct information. In the case of Binary

mode, the message length must also be stored as part of the command. The delimiting characters (<CR> in ASCII

mode and <STX> in Binary mode) should not be stored.

This system parameter can only be written for the Write System command, so there is no Read System and

Write/Read Memory support for this system parameter.

If no command needs to be executed upon power up, then a single-byte data value should be written to this system

parameter. This process turns off the Start Up command functionality. The single byte can be any value, for example

0x00 – 0xFF.

Write System Parameter – Startup Command Example (ASCII)

The following request stores the Select Tag (0x14) command with tag type ISO-15693 (0x01) to be executed upon

startup. Since the command is stored in ASCII mode, the response upon power up is sent in ASCII mode.
