Modbus Address: This parameter can be set to a value between 1 and 247. The value set must be
unique on the line where the product is found. Otherwise, communication of the line, to which the
product is connected, will be disrupted.
Bit Rate: This parameter can be set to one of the following values: 2400, 4800, 9600, 19200, 38400,
57600, 115200 or 256000 bps. The value of this parameter must be the same as the value in the
software you use to communicate with the product. Otherwise, you cannot communicate with the
product.
Parity Bit: The parity bit can be set to N/A, single or double. The value of this parameter must be the
same as the value in the software you use to communicate with the product. Otherwise, you cannot
communicate with the product.
