GINEERS M-BUS Series Instruction Manual

- GET CONN – returns current firmware version, LAN/WAN network parameters
(MAC-address, IP-address, gateway address, network mask, connection retries and
the time between two retries) and remote reading network parameters (baud rate,
parity, message timeout).
GET MEDx – returns allowed mediums for data operator x, x=1-4. The mediums
-
can be programmed only remotely by control operator.

3. Electrical connections

All the connectors of MBЕТ-2 are at the back of
the device and are shown on the figure on the right:
1 – Power inlet: adapter 6-9 Vac/200 mA or 5-12 Vdc/200
mA (polarity does not matter)
2 – RS232 RJ45 - for connection to an m-bus converter (MBRS-xx) or PC for initial
programming
3 – RJ45 – to LAN/ Internet
The cable, connecting MBET-2 to an m-bus converter type MBRS (RS-232 RJ45-RJ45 cross)
is part of the package.
The cable for initial programming (RS-232 DB9-RJ45 cross) is not delivered with MBET-2 as
it is part of the package of every m-bus converter type MBRS.

4. Warranty

The warranty of the device is limited to 3 years from the date of sale. If the device
shows any defect or malfunctions during that period, the manufacturer is obligated to repair
the device in its own service for manufacturer's expense, or, if the repair is impossible, to
replace the device with new one. The transportation costs to the manufacturer's service are
due to the client. The warranty voids if this manual' instructions are not met, warranty seals
are removed or the device was opened by unauthorized by the manufacturer personnel.

Instruction manual
MBET-2 is an internet/ LAN data transceiver for use in remote reading systems,
mostly m-bus. It has one RS-232C interface for connection to the network master converter
(like MBRS-xx) and for initial programming.

2. MBET-2 operation

MBET-2 is powered by external adapter 6-9 Vac/200 mA or 5-12 Vdc/200mA. The
central pin of the power connector is 2mm thick. We recommend adapter with power rating
6-12 Vdc/5W. Power supply voltage should not exceed 20 Vdc/ 15 Vac.
МBET-2 begins operation immediately after power-up. After initialization (about 2s),
MBET-2 enters "Command mode"/ checks for connection time, if device is set as remote
client. The connection with servers can be initiated by MBET-2 (acts as a client) or from
external network (MBET-2 acts as a server). The mode of MBET-2 is configured with service
command through RS-232 interface. All of the contacted servers/clients must have static
real IP-addresses in order for MBET-2 to be able to connect to them (or proper routing must
be done by system administrator). MBET-2 can contact up to six servers/clients – two
"control" operators and four "data" operators. The two control servers/clients can program
all network access settings and have no access to the transmitted data. Otherwise, the data
operators can access only the data, but cannot program any network parameters. If it is
needed for an operator to have access both to the network settings and the data, its IP-
address must be set both as control and data operator. Accessible mediums for every data
operator may be programmed, so, for example, the operator which monitors water
consumption, cannot access the data, monitored by gas supplier and vice-versa.
If device is set as client, MBET-2 tries to connect to the remote servers after
predetermined period of time (default 1h). Each of the servers can accept or reject the
incoming connection. If the connection is accepted, MBET-2 starts with identification data
packet to identify the remote reading network, connected to this particular MBET-2. After
identifying the network the server can reprogram network parameters (for control operators)
or access network data (data operators). After reprogramming the parameters or gathering
the data, the server sends packet for closing the connection. After receiving this packet,
MBET-2 closes the connection and tries to connect to the next server in the list until all the
