Data bits
Only 8 data bits can be selected here which is a requirement for RTU.
Stop bits
Can be configured to be 1 or 2. The Modbus standard mandates that 2 stop bits are configured when
using no parity.
Parity
Changes parity mode to either none, even or odd. The default parity mode for Modbus is even parity.
Slave ID for RS-422 node
This setting is only valid for the combined RS-485 + RS-422 mode which allows operating one RS-422
device and a RS-485 bus one the same serial interface. This setting determines based on the slave ID
whether a Modbus message is transmitted onto the RS-485 bus or the RS-422 interface. Configure here
the slave ID of the RS-422 device.
Once you click Save the new settings are stored and applied instantly. A confirmation message is shown.
5.3.3 Remote restarting the device
You can perform a remote restart of the device from the web interface. A remote restart is similar to power
cycling the device. Possibly connected clients are disconnected and communication is interrupted until the
device has rebooted.
To perform a remote restart, click on the Configuration sub-menu and then click on the Restart menu
entry. This will open the device restart page as shown below:

Click on the Restart button to perform a restart of the device. The restart is confirmed with the following
notification:

Please allow a few seconds before continuing working with the device as it has to fully start-up first, before
being able to respond to further web browser requests.
Note
After a remote restart a Watchdog reset alarm is shown on the device' home page. This is a
side-effect of the remote restart procedure and the alarm shall be ignored and cleared.
