Manual MWS 55 / MWS 88 / MWS 10 and Sensors 55
4.4 TCP/IP-Port with PoE
Another option of the MWS 55 is the TCP/IP port with PoE.
If your MWS 55 is equipped with this option, the unit can be power supplied via a network cable
and send the data over it's IP-address (port 20002).
The data cable length should not exceed 50m!
When running the unit over PoE there are lots of possible settings.
You may set a master having full control to the unit. this can be a MAC-address, an IP-address
or a range of IP-addresses.
Up to 15 clients can have access to the unit, preferred only reading to avoid command conflicts
when controlling the unit.
You can read the addresses of all connected units and you can read the receive and send statistics.
Also a FTP client is included for access to the data on the internal SD-card.
The commands for TCP/IP operation you'll find
4.4.1 Reading the data logger over PoE (TCP/IP)
In PoE mode (TCP/IP) there is a limitation reading the data logger.
The transmission rate set for the serial port is also valid for the transmission over TCP/IP.
If this speed is too high, a buffer overflow may occur causing that not all data in the data logger
can be transmitted over the TCP/IP interface. This leads to gaps in the data file.
Therefore the transmission rate should not exeed 19200 baud if you want to read the data logger
via the PoE (TCP/IP) interface.
This limitation applies to firmware version up to 3.0207.
4.4.2 Accessing the SD-card via FTP
Since firmware version 3.0221 a FTP client for accessing the SD-card is included.
Access to the SD-card is protected with a password.
The user name is ADMIN, the password is the 7-character serial number of your weather station.
Access to the SD-card is possible with a file manager (Total commander, Speed commander, i.e.)
or via a browser.
For accessing via a browser you type into the address line:
ftp://ADMIN:xxxxxxx@<IP-address>, where xxxxxxx is the 7-character serial number of your
weather station, i.e.:
ftp://ADMIN:[email protected]
CAUTION: If you set an admin password (*ADMIN SET PASSWD), then FTP-access to the SD-
card only is possible with this admin password and the admin IP-address!!
For access to the station with the
