General
1.1 About this manual
This manual will give you the guidance to install and connect the PiiGAB M-Bus 900 to your
network. It demonstrate how you connect to network, RS232, RS485, M-Bus Slave and the M-
Bus Master output as well as how you configure the module based on your requirements
1.2 Functional overview
The PiiGAB M-Bus 900 works as an interface between the Ethernet/RS232/RS485/M-Bus slave
entrance and the M-Bus network. The gateway is completely transparent which means that the
M-Bus questions asked via Ethernet are transferred out on the electric M-Bus interface. The
same goes for the answers sent from the meters via the gateway.
The gateway also has the option to add different software modules to meet requests such as
conversions between protocols, reading the same meter from different clients and sending files
to a database etc.
1.3 Advantages and possibilities
•The possibility to choose between TCP/IP or UDP/IP
•The gateway can be used with a fixed or a dynamic IP number.
•It is not dependent on any specific operating system, which means it can be used with
both Linux and Windows.
•There is a possibility to use password protection to prohibit unauthorized to change the
configuration.
•Communicate with up to four clients at once.
•Read M-Bus meters via Modbus (TCP/RTU).
•Read Modbus meters or other Modbus equipment’s via M-Bus.
•Local and central reading of the same meter from different directions at once.
•Connect to existing M-Bus network.
•Makes it possible for redundant communication.
•Read meters via M-Bus and Modbus at the same time.
•Read a few M-Bus meters without external M-Bus drivers via M-Bus ASCII.
•Can upgrade number of M-Bus loads (meters) and number of clients via a software
license.
•Via the QuickPost application can meter values be logged and pushed to an FTP or
HttpPost server.
•Read virtual M-Bus meters.

Technical structure
The gateway’s interface consists of one Ethernet connection, one RS232, one RS485, two
separate M-Bus slave inputs, four parallel outputs for M-Bus loops, two digital inputs and one
relay output as well as a voltage connection.
There are ten leds on the front of the gateway with different kind of information please see the
table in section 2.2.

2.2 Indications
The description of the different leds is in the front. By using the leds it is easy to simply follow
the traffic from different M-Bus clients and how the traffic moves via the masterport and the
meters.

2.3 Reset button
The reset button is located between the supply voltage connection and Ethernet 1. See the
picture below.
The button is located under the cover and can be reached by using a small screwdriver.
However, use with care and don’t use a pointy screwdriver that can end up next to the button.
With the reset button you can restart the PiiGAB M-Bus 900, set the network settings to default
(DHCP plus random IP address) or to change the Web login to default (Admin, Admin).
The reset button should be used in the following way. Push the button until chosen led is light
up, when the led is flashing fast you will push the button again and the chosen function will be
executed.
Example: Push the button once and the P1 (Rx) will light up. Wait until the P1 (Rx) is flashing
fast and then hold down the button again. In the event of pushing the button whilst it is flashing
fast you will automatically restart the PiiGAB M-Bus 900S/T. If you don’t push whilst the light is
flashing nothing will occur.
The table below describe the functions of the button:
Table 2-2
