  • Page 3: Introduction

    Nokeval’s third generation Sky radio devices use the Semtech LoRa modulation technique on the 433 MHz ISM band that allows unforeseen wireless range for battery powered transmitters. The protocol used is defined by Nokeval, called Sky, which means that these devices are not compatible with the LoRaWAN infrastructure.
  • Page 4 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. This is set at the factory and there is no need to change it. The address is visible in the back label of the device.

  • Page 5: Installation

    Installation location must have one free AC socket for the power supply. Connections Every Cell-Sky-Link-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...
  • Page 6 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. Symbol Description +VDC Power supply positive pin, 18…28 VDC RS-485 bus D0 pin Power supply negative pin, RS-485 bus ground RS-485-bus D1 pin The diagram below presents the connector pinout looking towards the base station’s female connector.
  • Page 7 This example picture illustrates how the base station can be connected to an RMD680 / RMD681 transmitter by sharing one 24 VDC power supply. The base 24 VDC station 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.

  • Page 8: 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 17: Usage

    Usage The base station will 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. Multifunction button In normal mode, LED bar indicates GSM signal strength.
  • Page 18 RS485 No queries are configured. Blinks green Queries are configured, and the base stations gets answers to them. Blinks yellow Queries are configured, but some of them don’t work. Solid red None of the queries work. GSM signal bar will display the fill state of RAM or FLASH memory buffer (to enter this state one must press multifunction button that is right above the power button) GSM signal bar will display the GSM signal strength.

    Maintenance Cleaning The device is made from shock-proof technical plastic and the seams are sealed with a rubber gasket. 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), the backup batteries (2 pcs size D alkaline cell) need to be replaced.
