Page 4: Introduction
One radio transmission can last approx. 2 seconds (compared to 20 ms of the Nokeval MTR series). This means that the number of transmitters within the range must be limited to avoid collisions and to allow radio time for each. -
Page 5: Installation
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 is central in relation to the radio transmitters. -
Page 6: Connections
Connections Power supply & serial RS-485 connector Inside the device, at the bottom right of the circuit board, is a four-pole spring cage / plug-in terminal block connector. It is a combined power supply and serial data connector. The table below describes the function of each connector pole. Symbol Description +24VDC... -
Page 7: Micro-Sim
RS-485 serial communication can be used to read results from external devices. The protocol can be Modbus, Nokeval SCL or also ASCII protocol for Vaisala WXT500 series weather transmitter. The RS-485 bus termination can be set with jumpers on the circuit board, as shown below. Extra jumpers can be put at the places marked in gray. -
Page 8: Backup Battery Case And Pol Connector
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. -
Page 9: 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. - Page 10 Protocol • Modbus • WXT5x0 Ascii • Baud rate 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 125000, 230400.

Page 19: Info
Info Info menu items are not configurable. They display various information about the device. Mon menu The monitor menu generally shows the status of the device and is mainly for manufacturer use. Many menu items purposes are clear by name, and most of them are not explained in this manual. -

Buffer memory: Buff1, Buff2, Buff3 and Flash sectors: If data arrives to the gateway faster than it can be send to the cloud, it stores the data in a buffer memory. First, the data passes through the device's RAM memories Buff1, Buff2 and Buff3. Data from memory Buff3 is sent to cloud. -
Page 21: Usage
Usage The base station does not require any continuous operation or intervention by the user. The device works independently and will not usually require attention after installation. However, from time to time, check that the device is still functional. LEDs The top five LEDs on the white background indicate the signal strength of the cellular network, the more LEDs light the better the signal. -
