1 Functions
The ZDUE-GPRS-PLUS-VI is a meter data transmission device. It is used
for remote reading and remote monitoring of electricity meters as well as
meters for other media.
Data transmission for remote reading and remote monitoring can take place
via:
one of the common GSM networks using the Circuit Switched Data
service (CSD)
one of the common GSM networks using the General Packet Radio
Service (GPRS)
In the following, the ZDUE-GPRS-PLUS-VI in CSD mode will be described
first. Different or supplementary functions in GPRS mode are described in
chapter 7.
With the ZDUE-GPRS-PLUS-VI, data transmission for remote reading and
remote monitoring can take place via one of the common GSM networks.
The ZDUE-GPRS-PLUS-VI supports the following GSM services
… CSD – Circuit Switched Data (Dial-up data connection)

The ZDUE-GPRS-PLUS-VI has the following interfaces for the connection of
meters: CL1, RS232 and RS485. The maximum permissible number of
meters can be connected to each of these interfaces simultaneously.
In addition, the device also has an auxiliary power source (9V) to supply the
meters.
For remote reading of the meters by the control centre, the ZDUE-GPRSPLUS-VI can connect all of the connected meters to the control centre in
sequence during a single connection. The control centre communicates
therefore with the connected meters directly. The ZDUE-GPRS-PLUS-VI just
transfers the data in both directions without modification. It only adapts
bitrate or data format, if the mode C function is enabled.
The integrated modem of the ZDUE-GPRS-PLUS-VI receives from the GSM
network data calls that have been initiated by the control centre.
The control centre can call
from the GSM network via a GSM modem (up to 9600 bps)
from the fixed network via an analogue modem (up to V.32; 9600 bps)
from the fixed network via an ISDN end device (V.110).
The ZDUE-GPRS-PLUS-VI that is called responds to the telegrams
transmitted by the control centre as follows:
It connects to the meters which are connected to its interfaces (CL1,
RS-232, RS-485).
It receives parameterisation commands and carries them out.

For protection against unauthorised access, password entry can be
configured. In this case the ZDUE-GPRS-PLUS-VI queries the caller for the
agreed password; the caller must then transmit it during the configured time
period (password timeout). If the password is incorrect or the timeout is
exceeded, the ZDUE-GPRS-PLUS-VI terminates the connection. The
password is parameterisable.

ZDUE-GPRS-PLUS-VI Page 11 of 63
Functions
Although the ZDUE-GPRS-PLUS-VI does not have a real-time clock, a timer
is operated on the basis of and with the accuracy of the processor crystal.
This timer controls the automatic module reset function that can be activated
and configured in parameter class 79.
The automatic reset cycle starts when the device is switched on, i.e. the first
module reset takes place after the parameterised period elapses after the
device is started. Additional module resets then follow at the time intervals
determined by the parameterised period.
The time for the daily watchdog (which is likewise configured in parameter
class 79) is not used by the ZDUE-GPRS-PLUS-VI.
Configuration by
software
Configuration is performed using configuration software, e.g. Dr. Neuhaus
ZDUEset. Parameterisation commands are transmitted to the ZDUE-GPRSPLUS-VI with the aid of this software.
The parameterisation commands can be transmitted to the ZDUE-GPRSPLUS-VI via the GSM network (remote configuration) or directly via the RS232 interface (local configuration).
Configuration by DIP
switch
Using the DIP switch inside the ZDUE-GPRS-PLUS-VI the operation mode
of the ZDUE-GPRS-PLUS-VI can be switched between Meter-Mode and ATMode. Refer to chapter 5.1 and 5.2.
Firmware update
A firmware update can be performed via the configuration software (e.g. Dr.
Neuhaus ZDUEset) from a computer that is connected locally directly to the
RS-232 interface of the ZDUE-GPRS-PLUS-VI.

Resetting to factory
setting
Pressing the service button once and holding it for more than five seconds
in ongoing operation deletes the parameterisation set in the device via
EN62056-21 commands. When the button is released the ZDUE-GPRSPLUS-VI is restarted, and when it boots it adopts the settings according to
firmware defaults.
Outputting the
firmware version
during booting
If the service button is held down during switch-on, the ZDUE-GPRSPLUS-VI outputs the current firmware version of the device via the serial
interface.
The data format of the connected terminal softare has to be set to 19200
Baud 8N1.
The DIP switch allows toggling between Meter Mode and AT-Mode. Refer to

The device conforms to protection class 2. The power supply to the
interfaces is electrically isolated from the electronics.
The antenna is connected to the type SMA
antenna jack. The position of the antenna
connection may vary depending on the device
type.
The antenna must be installed in such a way that
adequate signal quality is achieved. Make sure
that there are no large metal objects in close to
the antenna (e.g. reinforced concrete), as they
may have an adverse effect on the signal quality.
If an exterior antenna is mounted out of doors,
its support bracket must be earthed for
protection against lightning. Have this work
done by qualified personnel!
Observe the instructions included with your
antenna.
Antenna
characteristics
The antenna that is used should have an impedance of about 50 ohms. The
antenna must be adapted to the frequency bands of the GSM network
operator you have chosen: 850 MHz, 900 MHz, 1800 MHz or 1900 MHz.
In Europa and China GSM 900MHz snd DCS 1800MHz are used, in USA
GSM 850 MHz and PCS 1900 MHz are used. Please ask your network
operator.
The match (VSWR) of the antenna must be 1:2.5 or better.
Use only antennas from the accessories for the ZDUE-GPRS-PLUS-VI.
Other antennas could interfere with product characteristics or even lead to
defects.

3.5 Configuring the device if necessary
Basic settings as
shipped
The ZDUE-GPRS-PLUS-VI is shipped with a predefined factory setting.
Depending on requirements, it may need to be reconfigured. This can be
done :
remotely via a CSD connection
locally via the RS-232 interface (if no active CSD connection is
present).
Configuration
options
Among other things, the password protection, interface speeds, data formats
and the PIN that is to used can be parameterised.
For detailed information on parameterisation, see the chapter 6.
Parameterisation
options
The PIN can be set
remotely via a CSD connection
locally via the RS-232 interface (if no active CSD connection is
present).
For detailed information on parameterisation, see the chapter , see the
chapter 6.
SIM cards that have
no PIN
With SIM cards that have no PIN, the PIN query is skipped; the GSM
module does not wait for the PIN to be entered, but rather tries to check into
the GSM network directly.
Response to a
correct SIM PIN
If the PIN function of the SIM card being used is activated, and the PIN on
the SIM card being used agrees with the parameterised PIN, then the device
automatically tries to check into the GSM network.
Response to an
incorrect SIM PIN
If the PIN verification fails, it is repeated one time. If the repeated PIN
verification also fails, the device is blocked for further attempts (PIN ERROR
status), meaning that operation is no longer possible even with a SIM card
with the correct number. The Status/Error LED indicates a SIM/PIN error
(see 2)
This status is retained after the power supply is disconnected and
reconnected. This prevents the SIM card from being blocked if a third failed
attempt is made, after which it could only be unblocked using the PUK
(Personal Unblocking Key).
Unblocking the
device
To unblock the ZDUE-GPRS-PLUS-VI, a SIM card with a deactivated PIN
function must be inserted in the device. After starting, the device attempts to
check into the GSM network, and the PIN ERROR status is also reset.
Alternatively, the ERROR status can be reset using the service command for
setting a new PIN (see 6.5.7). This simultaneously sets the PIN
parameterised in the device.
