MGW/920 Smart Metering Gateway- First Steps

Manual Revision 1.1

1 INTRODUCTION

The default configuration of an MGW/920 Smart Metering Gateway contains one

10/100 Mbps Ethernet LAN interface and one M-Bus master interface for up to ten external

M-Bus meters.

For using the MGW/920 you need an Ethernet link to your PC or to an Internet router. This

link needs a standard Ethernet patch or cross-over cable.

1.1 Safety Guidelines

Please read the following safety guidelines carefully! In case of property or personal

damage by not paying attention to this document and/or by incorrect handling, we do

not assume liability. In such cases any warranty claim expires.

ATTENTION: Observe precautions for handling – electrostatic sensitive device!

•Discharge yourself before you work with the device, e.g. by touching a heater of

metal, to avoid damages.

•Stay grounded while working with the device to avoid damage through electrostatic

discharge.

1.3 Application Environment

Figure 1 shows the typical application environment for the MGW/920 Smart Metering

Gateway. One side is connected over the M-Bus (metering Bus) to gas, electricity, water or

other types of consumption meters. The other side offers an IP-based Internet link via wired

xDSL (Ethernet) or wireless GPRS (GSM/GPRS modem).

The application environment allows the transfer of energy consumption data over the Inter-

net as an IP-based network to IT-hosted monitoring, billing or management applications in

real time.

3 GETTING STARTED

3.1 Ethernet Link between MGW/920 and PC

Setup the Ethernet link between the Ethernet connector of the MGW/920 and your PC.

Use an Ethernet cross-over cable or a router-based infrastructure for the Ethernet connec-

tion.

Fig. 3: Ethernet link between MGW/920 and PC

Please note: The MGW/920 comes with the default IP address 192.168.0.126.

Please make sure that your PC can work with the IP address range 192.168.0.x.

3.2 Connecting Power Supply and Power-up the MGW/920

Connect the 12 VDC power supply with the 5.5 mm x 2.5 mm barrel plug to the

MGW/920.

Fig. 5: Power supply for the MGW/920

CAUTION: Providing the MGW/920 with a voltage higher than the regular 12 VDC

±10 % could resolve in damaged board components!

Please pay attention to the polarity of the power connector: the + pole is in the center!

3.3 Checking IP Address of PC

Make sure that your PC is using the right IP address for the Ethernet-based TCP/IP com-

munication with the MGW/920. Use 192.168.0.1 or 192.168.0.254 for your PC and

192.168.0.126 for the MGW/920.

Fig. 7: Windows-PC IP address check with ipconfig

Talk to your network administrator if you have problems with the IP address understand-

ing.

3.4 Checking Ethernet-based TCP/IP Communication

Check the Ethernet-based TCP/IP communication between the MGW/920 and the PC

with a simple ping command.

Fig. 8: Windows-PC TCP/IP communication check with ping

First check the cable connections and then the IP addresses if your ping does not work.

Then check the TCP/IP setup of your PC.
