Kobold ZLS-2 - 9.1. LIST OF REGISTERS

User manual - DATA RECORDER and cooperating software
9. THE MODBUS PRO TOCOL HANDLING
Transmission parameters: 1 start bit, 8 data bits, 1 stop bit, no parity control
Baud rate: selectable from: 1200 to 115200 bits/second
Transmission protocol: MODBUS RTU compatible
The device parameters and measurement result are available via RS-485 interface, as
HOLDING-type registers of Modbus RTU protocol. The registers (or groups of the registers)
can be read by 03h function, and wrote by 06h (single registers) or 10h (group of the registers)
accordingly to Modbus RTU specification.
