Configuration
When configuration is made via the serial-port adapter 2 is used.
Connect the adapter to the COM port and the straight module cable between the
adapter and the gateway’s RJ-12 contact.
The Ethernet connection is being configured without connecting the network with
this type of connection.
Example of usage:
You have chosen to protect the gateway to prevent unauthorized to affect
the internal settings. With some settings you have to choose this way to
be able to make configuration changes yourself like, baudrate, port
number, IP address etc.
The gateway has been configured before over the existing network and is
in full usage. During a service occasion you want to change the baudrate
for the gateway, because adaptation is being made of a newly installed
meter, which is using a different baudrate than the earlier setting. This
can be preformed on scene with adapter 2 without that the technical staff
has to connect themselves via the network.
6.4
Ethernet to serial
If the gateway is being used as a Ethernet/RS232 gateway adapter 3 is used.
Connect the adapter with the equipment that you want to establish communication
with. Use the straight module cable between the adapter and the gateway’s RJ-12
contact.
When this connection is used the 810 gateway is like a gateway between Ethernet
and RS232 (port-server). This makes it possible to connect other equipment that is
using RS232 communication. Observe that the hardware handshaking signals are
not connected.
Example of usage:
You want to connect a meter that only supports the electrical interface for
RS232 and not the one for M-Bus. Although the protocol is still M-Bus.
You want to connect other types of meters, plc, or remote units over the
net as a RS232 connection. Since the gateway is protocol transparent you
can use any protocol you want like for example comli, modbus etc.
6.5
Spy
All traffic being send or received on the M-Bus port are mirrored to the serial port.
This means that different types of programs can be connected for monitoring. To
be able to both write and read you need two communication ports on your
computer.
