RS-485 PORT
Configuration
The
RS-485
port can be configured for
BACnet
or
Modbus
on the
RS 485
>
Configuration
page, and the baud
rate can be set as appropriate. See
Configuring a Modbus RTU connection
Status
The status of the ports can be viewed on the
RS 485
>
Status
page. It includes the number of characters
transmitted, and also received errors.
Note
: If the
RX errors
value is a large percentage of the
RX characters
value (for example > 10 %), it may be
beneficial to review your wiring for correct termination or unexpected line breaks.
Serial Captures
If required for diagnosing errors or tuning network performance, the
CBXi
can capture serial port
communications and store it in a file that can be analysed using
WireShark
.
This is done through the
RS-485 Ports
