1 Device description
1.1 Scope of application
The communication unit CU-P4x can be fitted in and removed from the fol-
lowing Landis+Gyr meters without opening the calibration seal:
Landis+Gyr E650 ZxD300/400xTindustrial and commercial meters
Landis+Gyr E850 ZxQ high-precision meters
Inserted in a CU-adapter CU-ADP2, the communication unit CU-P41 or
CU-P42 can also be used with other meters (e.g. Landis+Gyr E650
ZxD300/400xR, ZMD100AR, ZxB or meters from other manufacturers).
Connection to the meter is made in this case via an interface in the
communication unit (CS, RS232 or RS485).
1.2 Characteristics
The communication unit CU-P4x contains a built-in GSM/GPRS modem
(mobile telephone modem with GPRS service for data transmission in
packet form in GSM networks) and, depending on the version, an RS232-
and a CS interface (CU-P41) or an RS485- and a CS interface (CU-P42).
It is used to supplement the meters listed above.
The GSM/GPRS modem serves to read out or re-parameterise the meters
from a central station via the mobile telephone network with GPRS via the
Internet. It can also be used as a normal GSM modem.
The RS485 and CS interfaces can be used for connecting meter points
over a relatively long distance compared to RS232. The CS interface can
be parameterised as an active or passive interface and thus can be used
as master or slave as required with multiple connections.
If a communication unit CU-P41 or CU-P42 is used externally in a CU-adapter,
one of the existing interfaces of the communication unit is required for connec-
tion to the meter.
1.3 Type designation
The type designation of the communication unit CU-P4x is added to that of
the meter (see meter user manual), but is not shown on the main faceplate
of the meter. It is specified directly on the case of the communication unit
and can be seen through the front door of the meter through an opening on
the tariff faceplate.
The communication unit CU-P4x is available in the following versions:

1.4 Functions
A functional description of the communication unit CU-P4x is provided
separately. The following main functions are briefly summarised below.
1.4.1 GSM/GPRS modem
The mode of operation can either be parameterised as GSM modem or as
GPRS modem.
The GSM modem (GSM = Global System for Mobile Communication) is
approved according to various standards such as 3GPP release 4. It is a
wireless modem (Modulator-Demodulator) for the modulated remote
transmission of data via the mobile telephone network. The GSM modem
uses the 850 MHz, 900 MHz, 1800 MHz and 1900 MHz GSM frequency
bands.
The GPRS modem (GPRS = General Packet Radio Service) uses the
GSM network for data transmission, but sends and receives the data in
packets. The packet-oriented data transmission permits network usage
billing based on data volumes transmitted instead of connection time.
GPRS permits a wireless connection to the Internet by means of transmis-
sion protocol TCP/IP (Transmission Control Protocol/Internet Protocol).
1.4.2 CS interface
The serial bi-directional CS interface is standardised to IEC 62056-21 or
DIN 66258. It supports both the communication protocol to IEC 62056-21
as well as communication according to dlms and can be operated both
actively and passively.
1.4.3 RS232 interface
The RS232 interface is an asymmetrical, serial, asynchronous, bi-direc-
tional interface to DIN 66259. This interface can be used for the (tempo-
rary) connection of a PC or laptop, in order to communicate with the meter
independent of normal data acquisition. The RS232 interface of the com-
munication unit CU-P41 has no control lines (3-wire version).
1.4.4 RS485 interface
The serial bi-directional RS485 interface is standardised to ISO-8482. It is
basically intended for the connection of several meters (up to 31) using the
CU-P42 as the master.

Installation/De-installation 15/40
D000043188 en d –E65C –CU-P40, P41, P42 –User Manual © Landis+Gyr
4 Installation/De-installation
4.1 Inserting a SIM-card
Insert a SIM-card in the communication unit as follows:
1. If present, remove a previously installed SIM-card by releasing it
(pushing it in) and withdrawing it.
2. Insert the SIM-card into the slot as shown below and gently push it in
until it engages. Once the SIM-card is properly inserted, it should not
extend beyond the side of the device.
Fig. 4.1 Correct insertion of the SIM-card

Keep SIM-card contacts clean
SIM-cards have electrical contacts that may come into contact with the user
during normal use. The presence of oils and dirt on these contacts may
cause corrosion on these contacts that are not apparent during the instal-
lation or shortly thereafter. Such corrosion may cause the contacts to
become unreliable and affect the option of the communication unit. It is
recommended that the user clean the contacts with a suitable solution or
perform the installation in a controlled clean environment to maximize the
operating life of the modem.

SIM with roaming disabled
It is possible to get SIM cards from Mobile Network Operators where
roaming is disabled. This is recommended in order to avoid higher service
charges when installing meters near the border of countries. There are
initialization commands that can also be added to the CU that can cause
the CU to select a pre-defined operator. This is the less preferred solution
and may cause GSM LED behaviour to change.
4.2 Fitting in meter
No voltage to meter when fitting
In order to avoid hazardous electric shocks, ensure there is no voltage
applied to the meter when fitting the communication unit. Contact with live
parts is dangerous to life. Disconnect the meter from the power supply as
described in the meter user manual.

16/40 Installation/De-installation
© Landis+Gyr D000043188 en d –E65C –CU-P40, P41, P42 –User Manual

Excessive Number of Power Failures reduces Life of Product
The CU writes to it internal FLASH memory every time that there is a power
failure. This type of memory has a life of approximately 100,000 write
cycles. This is not a guaranteed value. For a life of 15 years, that amounts
to approximately 15 power failures per day. Environments exceeding this
limit may shorten the useful life of the product.

Older version of CU should not be used in new meters
The CU is designed to be interoperable with all existing meters at the time
that it was designed. Once a device is obsolete and is replaced by a newer
version of the product, interoperability testing stops. This means that older
CU product that have been in the field for some number of years should not
be used with new meters even though they can be inserted into the meter.
Fit the communication unit in the meter as follows (with SIM-card inserted
according to section 4.1):
1. Ensure that no voltage is applied to the meter.
2. Remove the utility seals on the front door and terminal cover.
3. Open the front door and remove the terminal cover.
Fig. 4.2 Preparing the meter for fitting the communication unit
4. Remove the built-in "dummy" communication unit.
5. Insert the communication unit carefully at the place provided in the
meter. Ensure correct fitting of the connector.

4.3 Fitting in CU-adapter CU-ADP2
No voltage to CU-adapter when inserting communication unit
There must be no voltage applied to the CU-adapter when the communi-
cation unit is inserted. Contact with live parts is dangerous to life. If neces-
sary, disconnect the CU-adapter from the power supply as described in the
CU-ADP user manual.
Fit the communication unit CU-P42 in the CU-adapter CU-ADP2 as follows:
1. Remove the utility seals on the front cover.
2. Remove the transparent front cover.
Fig. 4.4 Preparing the CU-adapter CU-ADP2 for fitting the communication unit
3. Insert the communication unit carefully at the position provided in the
CU-adapter by first moving this forwards under the cam and then
pressing down at the rear. Ensure the correct fit of the plug. The front
cover should only be replaced after connecting.
Fig. 4.5 Fitting communication unit in CU-adapter CU-ADP2
4. Connect the communication unit to the meter (via RS485, RS232 or
CS interface) and the adapter to mains and mount the front cover, see
User Manual of the CU-adapter.

4.4 Connecting the communication unit
4.4.1 Connecting the antenna
Connect the antenna of the communication unit CU-P4x as follows:
1. Insert the plug of the antenna cable from above in the antenna socket
of the communication unit.
Fig. 4.6 Connecting antenna
2. If necessary: File a small hole for the antenna cable in the terminal
cover at the required point with a round file.
3. Set up the antenna with magnetic base so that a good reception may
be expected (see following section 4.4.2 "Choosing the most suitable
antenna position in GSM mode").

Antenna cable
Ensure that there are no physical forces acting on the antenna cable.
The antenna plug fitted on the circuit board could otherwise be torn off.

Always operate with an Antenna
The CU should only be operated with an antenna. Operating without an
antenna for extended periods of time is not advised. Failure to do so may
violate electromagnetic emission regulations, unreliable operation of device
or damage to device.

Do not operate device where Mobile Phone Operation is prohibited
The CU emits radio frequencies complying with EU R&TTE and EMC
directives. There are additional restrictions that may be locally imposed
such as hospitals and operating rooms where radio equipment is strictly
forbidden. In addition, areas where there is risk of explosions such as gas
stations and oil refineries.


Conforming to RTT&E Safety aspects
In order to comply with Specific Absorption Rate (SAR) specified as part
the RTT&E directive, the installation must fulfil the following points:
Antenna must not be installed directly (<1 m) beside people and
other equipment.
Antenna must have a gain less than or equal to 1.4 dBi at 850 MHz
and 900 MHz and a gain less than or equal to 3 dBi at 1800 MHz
and 1900 MHz.

Positioning of antenna
When setting up the antenna, movable objects such as doors and windows
should be positioned in the same way as when the meter is to be read. For
example, if doors will be closed after the installation during operation, the
signal strength is only valid when the door is closed. Avoid places where
moving metal objects can be found (e.g. cars in a garage).

The effect of weather on signal strength
Humidity, rain and lightning can affect signal strength measurements as
well as the frequency band being used. Additional margin beyond the
minimum signal level is needed to ensure reliable operation.
