How does the reliability of the physical layer influence the choice between simple error detection and more complex error correction?

1 Stop Bit and an Odd Parity bit. 2.4 Modbus RTU function Code Support. Function Code 4 – “Read Input Register” is supported. Jan 14, 2025 ... I have two devices on a Modbus RTU line. Device 1 is only supports NONE for parity while Device 2 supports NONE, ODD or EVEN parity by changing the ... Mar 4, 2014 ... At a minimum you should support 9600 & 19200, plus No and Even parity.
