Step 9: Configure the RS232/RS485 Data Settings Pane (8)

The NETNode can send and receive data through its RS232/1, RS232/2 or its RS485 serial

port. See

Controls, Connections and Indicators

to find out which port you are using.

Description

Data Mode

Off

UDP

TCP Server

TCP Client

Off – Data transfer is switched off.

UDP - UDP (User Datagram Protocol) is used to

move data about the network. The packets are sent

out and the system does not expect a reply. There is

no way that the sending device can tell if the data

arrived at the destination.

TCP - TCP (Transmission Control Protocol) is used to

move data about the network. The packets are sent

out and the system will expect a reply. Each

message is acknowledged by the destination device.

Setting TCP server allows applications such as

telnet to connect to the port.

Setting one NETNode to TCP server and one to

TCP client allows data pipes to be formed.

Default is OFF.

Baud Rate

Speeds available

are: None,

Illegal, 1200,

2400, 4800,

9600, 19200,

38400, 57600,

and 115200.

This is where you set the speed at which data will be

transferred across the network.

Note: The data is assumed to be eight bits.

Default is 4800.

Parity

None

Even

Odd

A parity bit is a bit that is added to make sure that

the number of bits with the value one in a set of bits

is even or odd. Parity bits are used as the simplest

form of error detecting code.

There are two variants of parity bits: even parity

bit and odd parity bit. When using even parity, the

parity bit is set to 1 if the number of ones in a given

set of bits (including the parity bit) is even. When

using odd parity, the parity bit is set to 1 if the

number of ones in a given set of bits (including the

parity bit) is odd. In other words, an even parity bit

will be set to "1" if the number of 1's + 1 is even,

and an odd parity bit will be set to "1" if the number

of 1's +1 is odd.

Default is None.
