Introduction
Ovazone-Cell-Link-MTR-RS485-3G is a base station for 2.4 GHz and 433.92MHz Nokeval-transmitters
and part of Nokeval Ovazone product family. It receives and buffers radio packets to its non-volatile
memory and transmits them over GSM to Ovaport network service, thus enabling reliable remote data
acquisition from the field straight to the servers located in a data center.
Serial interface
The base station can be connected to standard Modbus RTU transmitters and to Nokeval devices with
SCL protocol using the integrated RS485 bus. The base station’s reliability is increased by theal backup
battery, which enables uninterrupted data acquisition also during external power interruptions.
Ovanet
Ovanet is Nokeval’s second generation radio network, which uses Wirepas Pino technology and
Nokeval’s own additions. The network uses 2.4-2.48 GHz band, which is available all over the world. The
product names basically begin with the Ovazone prefix.
Every device in the network, also battery powered ones, will function as a repeater by assisting devices
located far away from the gateway, effectively forming a mesh network.
The network has node devices producing measurement data, and one or more gateways. The gateway
connects the network to other systems. Examples of the gateway devices are Ovazone-Wave-Link and
Ovazone-Cell-Link. They are used to deliver the data of the radio network to the Ovaport service.
Each device, including nodes and gateways, has to be set with the same Ovanet network. The Ovanet
network number has to be chosen between 1-16777214. It should be generated with a random number
generator, to minimize the probability to accidentally choose the same network number as in another
network located nearby. By default, the devices are set to the network number 6829663, which can be
used if there are no other Ovanet or Wirepas Pino networks within a couple of hundred meters. If two
networks have the same number by accident, the node devices may connect to a wrong network and
the data is not delivered to the desired gateway.
Each device has a unique Ovanet address. It is set at the factory and there is no need to change it. The
address is visible in the back label of the device.
The devices automatically change their radio frequency seeking suitable frequencies in the crowded 2.4
GHz band. However, at power-up the devices need to find other devices in the network, for which a
common radio frequency is needed. All the devices of the network need to be set to the same radio
channel between 1-28. Usually the default channel 1 is ok.
There is no need to configure any other radio network settings. The network searches automatically for
the best connections and updates them if needed.
The open space range between the nodes is about 200 meters and indoor range is some tens of meters
depending on the construction materials. Placing the devices near a metal surface will decrease the
range.

Installation
Wall holder
Install the base station to a wall or some other suitable surface with the separate wall holder. See the
following dimensional drawing for the wall holder’s mounting hole distances. Use fastening accessories
suitable for the wall material, like plugs and screws. The screws need to have a countersunk head.
Installation location
Choose an installation location that it is central in relation to the radio transmitters.
The base station has to be installed vertically. The base station is splash proof, but the location has to
be chosen in a way that will not expose it to water or hot steam. Please note that the AC socket and the
power supply are not splash proof.
The location must have GSM/GPRS/3G network coverage. This can be verified before the final
installation steps by powering on the base station and checking coverage icon on the display.
Installation location must have one free AC socket for the power supply.
Connections
Every Ovazone-Cell-Link-MTR-RS485-3G base station model has one or two connectors in the lower part
of the enclosure. Every model has an M12 type female connector (receptacle) and a detachable male

5
connector (plug). The connector has four pins and it is a combined power supply and serial connector.
The table below describes the function of each pin.

connector. The same pinout is valid for an opened male connector looking towards the terminal
screws. Please note the polarizator location in the diagram between pins 1 and 2. The detachable M12
connector supplied with the base station has numbering inside the connector next to the screw
terminals.

This example picture illustrates how the base station can be connected to an RMD680 / RMD681
transmitter by sharing one 24 VDC power supply.
RS-485 bus information
RS-485 is a serial bus type commonly used in the industry. It is based on two data lines D0 and D1,
which are connected in parallel with all the devices connected to RS-485 bus and D0 and D1 pins. To
even up the electric potential between different devices, a third wire is also needed. In the above
example picture the blue ground wire evens the potential differences between the devices. Branches in
the bus should be avoided, in other words the bus cabling should circulate through all the devices
without branches. The maximum recommended length of the bus is 1 km. The cable should be twisted
pair and the wire diameter should be at least 0.5 mm.
To ensure EMC compliance the RS-485 bus cable should no more than 30 meters long.
The bus is bidirectional. Only one device at a time can send data, during which other devices listen.
Only one device connected to the bus is set as master, in other words as a chairman, which starts all
conversations on the bus. Other devices are slaves and they only answer to queries of the master. Each
device connected to the bus has its unique bus address, which the master device uses to direct its
commands to a specific device.
The base station functions as an RS-485 bus-master and queries the measurement data from other
devices on the bus. In a typical application, such as the one presented in the diagram above, the base
station regularly queries the RMD680 / RMD681 transmitter’s measurement data and sends it to the
Ovaport server.
Radio receiver antenna connector
The base station top part has the radio receiver’s female BNC connector. The base station is supplied
with a suitable antenna. Attach the antenna to the connector to complete the installation.

Configuring the device
There is usually no need to configure the device since most of the settings are already at their best
defaults. However, if you want to see what kind of settings there are or edit settings, use MekuWin
program and DCS772 (USB-POL converter). You can download MekuWin from Nokeval’s web site
www.nokeval.com for free.
Connection settings
Communication settings for configuration:
 baud rate 9600
 protocol SCL
 address 0
Programming connector
The device has a 3PIN POL programming connector. Use POL-3PIN adaptor to connect the DCS772 to
the device. The 3PIN POL programming connector can be connected in both ways.

The base station will not require any continuous operations or actual use from the user. The device
works independently and will not usually require operations after installation. However, from time to
time, check that the device is still functional.

Maintenance
Cleaning
The device is made from shock-proof technical plastic and the seams are sealed with a rubber casket. It
can be cleaned by wiping with a damp cloth.
The device is not meant to be immersed into water or other liquids.
Service
If Bat LED indicates low battery voltage (red, see above BAT LED), batteries (2 pcs type D) need to be
replaced.
The device does not need other regular service or maintenance.

19
Troubleshooting
The base station cannot connect to GSM-network.
Is the SIM-card installed inside the base station? Is PIN-code set with the setting application? Is there
a sufficient coverage at the installation location? If needed, contact support.
The update was not successful.
The battery level needs to be above certain level to start the search for the new firmware. If the
search will not start, change the battery and try to find a place with a better GSM-coverage or more
reliable Ethernet connection. The battery level needs to be above certain level, to start the flashing
of new firmware.
If the update will not work at all or you want to send the device for service contact Nokeval support
with the contact information given below.
