12. If the DLU is not yet connected to the network, create the LAN connection to the
network and press
Restart Data logger?
and
Yes
.
13. The logger restarted and the network configuration is completed.
14. The connection can be tested in various ways. The various connection tests are
described in chapter 4.5.2.
4.5.3.2.2 IP set via maintenance commands
The setting of the DHCP mode, the IP address, the gateway and the subnet mask can be
done with remote maintenance commands via the serial interfaces and Telnet. For this
purpose, a computer with a terminal program e.g. Tera Term are necessary.
The DLU has the following serial interfaces available:
1. Micro USB, can always be used for configuration.
2. USB is only available for WLAN connection.
3. COM1, function depends on the configuration (optional)
4. COM2, function depends on the configuration (optional)
Note:
Setting the IP address via Telnet and WEB is only possible if the DLU already has a valid IP
address in the network, e.g. with dynamic IP assignment.
Depending on the delivery condition, only the micro USB interface can be used for
configuration or COM1, COM2 and Telnet via Ethernet.
Note:
COM1 and COM2 can be configured as RS485 half or full duplex! Only a COM that is
configured as a Mevis output in the combination circuit diagram can be used!
Note:
The user login is required to change the IP parameters via serial interfaces and Telnet.
To change the IP address, the following steps must be performed:
1. Establish a connection between a computer and the DLU and start the DLU. The
connection can be made via the micro -USB connection to the computer. Optionally,
COM1, COM2 (RS485 half or full duplex) or a Telnet connection (LAN) are possible,
depending on the configuration.
2. The computer should automatically recognize the serial interface after a few seconds.
3. Start the terminal program and establish the connection to the logger. To do this, go
to the Settings / Serial Port menu in the terminal program, select the COM, set the
baud rate to 115200 baud for micro USB (COM1 & 2 may differ), 8 data bits, none
parity and 1 stop bit. Close the window with OK. This enables communication with the
