The cable, connecting MBGP-3 to an m-bus converter type MBRS (RS-232 RJ45-RJ45 cross) is part of the
package. Cross means that pin 2 from one side goes to pin 3 on the other and vice-versa.
The cable for initial programming (RS-232 DB9-RJ45 cross) is not delivered with MBGP-3 as it is part of
the package of every m-bus converter type MBRS.

Ethernet/Internet modem MBGP-3EP
MBGP-3EP is a GSM/GPRS 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. In addition, 4 pulse inputs for connecting meters are provided. It operates in GSM
networks and needs operational SIM card (mini SIM) with activated GPRS service.

2. MBGP-3EP operation
МBGP-3EP begins operation immediately after power-up. After initialization (about 2s), the
programmed MBGP-3 enters "Command mode"/ checks for connection time. The connection with servers
is initiated by MBGP-3 (client). All of the contacted servers must have static real IP-addresses in order for
MBGP-3 to be able to connect to them (or proper routing). MBGP-3 can contact up to six servers – two
"control" operators and four "data" operators. The two control servers 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.
MBGP-3 tries to connect to the servers after predetermined period of time (default 15 minutes). Each
of the servers can accept or reject the incoming connection. If the connection is accepted, MBGP-3 starts
with identification data packet to identify the remote reading network, connected to this particular MBGP-
3. 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, MBGP-3 closes the connection
and tries to connect to the next server in the list until all the servers in the list are contacted. Then MBGP-
3 waits for predetermined period of time before attempting to connect again to the first server in the list.
If the connection is accepted by the server, but then there is no communication for predefined period
of time (default 60s), MBGP-3 drops the connection and goes to the next server in the list. The connection
is dropped from the server, if idled, after 180 seconds. The device has two leds – first indicating power is
applied to the device, and the second is lit or blinks when GPRS is active and RSSI info can be read from
the network. If the second LED is lit, then the signal strength is better than -75dBm, if the LED blinks, it is
below that value. If this LED is off – no GSM/GPRS connections available.
Initial parameters programming is essential and includes setting the connection parameters (Access
Point Name, user id, password, SIM PIN) and remote reading network parameters (baud rate and parity of
serial connection, remote reading network number). These parameters must be set first, and after
successful connection all the parameters can be set remotely by the server.
