TCP server settings
TCP connections are always bidirectional, so no separate transmitter and receiver settings
are needed.
Advanced settings
RS-4xx settings and data transfer optimization
For details about ‘data words’ and data transfer optimization, see the note below.
Bit rate
[300…115200]. Enables you to set a bit rate other than the presets in the
UART settings section.
UART gap
timeout
[0…255] data words. Will have the next packet sent when the line has
remained idle for longer than the timeout.
UART max.
latency
[0…255] data words. The maximum latency of the data channel is
controlled by
forcing a packet to be sent when the first data word of the
packet was received longer ago than the number of word times set here.
Line
termination
enable
Normally, the devices at the two extremes of a bus are terminated, while
intermediate devices are not. Therefore: RS-422, always enable (being
point-to-point); RS-485, enable only for the first and last module
connected to the bus configuration.
Line biasing
enable
If biasing is needed (RS-485), it should be enabled on at least 1 module
on the bus. RS-422 does not require biasing
.
Server Enable
Selecting the check box will enable the streaming of UART data over TCP
using a client/server connection. The server accepts requests from a
specific client, or any host if not specified.
Server port [0…65535].
