Register description

The registers are used to parameterize the terminal. They can be read or written by means of the register communication.

R6: Diagnostic register

Status byte SB is placed into register R6.

R7: Command register

No commands are implemented in this terminal.

R8: Terminal description

The name of the terminal is contained in register R8. KL6021: 0x1785 (6021_dec)

R9: Firmware version

Register R9 contains the ASCII coding of the terminal's firmware version, e.g. 0x3541 = '5A'. The '0x35' corresponds here to the ASCII character '5', while the '0x41' represents the ASCII character 'A'.
This value cannot be changed.

R16: Hardware version number

R29: Terminal type - special identification

The name of the special type of the terminal is contained in register R29. KL6021-0023: 0x0017 (0023_dec)

R31: Code word register

If you write values into the user registers without first entering the user code word (0x1235) into the code word register, the terminal will not accept the supplied data.
If you write values into the user registers and have previously entered the user code word (0x1235) in the code word register, these values are stored in the RAM registers and in the SEEPROM registers and are therefore retained when the terminal is restarted.

The code word is reset when the terminal is restarted.

R32: Feature register

The feature register specifies the terminal's configuration. There are no configurations that can be made for this terminal.
