- Page 23 ◀ ◀ U900 Universal Analytical Controller Operating Manual MODBUS RTU Transmission Mode When the instrument uses RTU (Remote Terminal Unit) mode for MODBUS serial communication, each 8-bit byte of information contains two 4-bit hexadecimal characters. The main advantages of this mode are greater character density and better data throughput than the ASCII mode with the same baud rate.
- Page 24 ◀ ◀ U900 Universal Analytical Controller Operating Manual MODBUS RTU CRC Check The RTU mode contains an error-detection domain based on a cyclic redundancy check (CRC) algorithm that performs on all message contents. The CRC domain checks the contents of the entire message and performs this check regardless of whether the message has a random parity check.
