Serial Menu

The Serial menu options relate to setting up serial services on each of the built-in serial ports on a

cnReach radio.

Serial/Local Serial Settings

This is where the physical connection to the Serial End Device is configured.

Interface type; RS232/422/485, Baud Rate, Data Bits, Parity, Stop Bits, Flow Control and RS485 Line

Delays can be adjusted to suit the required application.

The default setting for Serial 2 is Data, which allows Serial Services to be configured.

The default setting for Serial 1 is Login, which allows access to the CLI for configuration.

Please refer to RJ-45 Serial Port Pin Assignments for cabling info.

Baud Rate is the speed at which the data is sent, in bits per second. Baud Rate must match between

both Serial Devices in order for communications to be successful.

Data bits is the number of bits in each character. This can be 7 for ASCII or 8 for most other types of

data. 8 data bits = 1 byte.

Parity can be used to detect errors in the data stream. Parity allows an extra data bit to be sent with

each character. This extra parity bit is arranged so that the number of 1 bits in each character (including

the parity bit), is always odd or always even. Errors are detected when a byte is received with the

wrong number of 1’s.

Stop Bits: cnReach always uses one stop bit and this is not adjustable.

Flow Control can be used when the serial devices require the transmission of data to be paused and

then resumed.
