User Manual Firmware version V1.07 19.8.2010 RTR970B-PRO FTR 970B-PRO RECORDABLE RADIO DATA RECEIVER

DESCRIPTION RTR970B-PRO and FTR970B-PRO have only one difference, the case. The benefits in upgraded B version: Antenna is moved to the middle in both models and FTR model is about half the size of the original. RTR970-PRO is a radio data receiver with data logging ability used with Nokeval MTR series wireless transmitters. Device can receive, unpack and buffer data packets into its memory from transmitters. It automatically identifies the type of a transmitter, so it can be used simultaneously with different transmitters and with different transmit periods. The device uses license free...

INSTALLING WHERE TO INSTALL The RTR model is 35 mm DIN-rail mountable and FTR is wall mountable. Desktop use is also an option. The best place for a receiver is a big grounded horizontal metal plane surrounded by as few as possible vertical metal surfaces. Antenna is to be installed perpendicular to the metal using angled connector or with extension cord. The best coverage for the transmitter is achieved when the receiver has line of sight to the transmitters. Every obstacle between the devices will attenuate the signal and thus decrease the range. On the other hand, metal surfaces will...

RS-485 To use RS-485-bus, jumper J11 has to be set according to the picture below. Device needs 8...30VDC power supply which is connected either with 1.3mm DC-jack, with positive center pole, or with terminal connections 1 (+) and 2 (-). DC-jack and terminal connector is connected in parallel. Device is protected against wrong polarity of power supply. RS-485 can be easily added to computer using Nokeval DCS770 or DCS771 USB - RS-485 converter or RCS770 USB/RS-232 - RS-485 converter. RS-485 is connected to terminal connections 3 (D1), 4 (D0) and 2 (Gnd). Wrong connection of polarity doesn't...

INDICATOR LIGHTS FRONT PANEL INDICATOR LIGHTS The following pictures are from the RTR970-PRO to make it easier to understand. Inside a FTR970-PRO there are no texts for the lights. PRO: Means that device is operating. RADIO: Means that device is processing serial communication command. MEMORY: Means that device is writing data to flash memory. ERROR: When power is applied to the device first time error is light almost certainly, since the real time clock is out of time in device. This error disappears when new time is set to clock either automatically with PromoLog or manually with MekuWin....

Installing drivers when using USB USB interface circuit needs two drivers for PC. First of them opens communication for the USB and the other generates virtual serial port. When PromoLog is installed on the computer it also installs these drivers automatically, but if PromoLog is not installed then you can follow instructions below to install the drivers. The drivers can be obtained from a Nokeval Software CD or downloaded from the homepage of Nokeval at www.nokeval.com. The installation below assumes using CD, but using downloaded drivers is quite similar. Insert the Nokeval Software CD...

Repeat this procedure for other driver (usb serial port). Finally open the “Device manager” to check which COM-port the device was attached to.

Connection settings Use Mekuwin program to configure the device. You can download Mekuwin from Nokevals web site for free. Mekuwin has its own instruction manual. Default settings for serial communication are: • baud rate 115200 • protocol SCL • bits 8N1

SERIAL-SUBMENU MODE Serial communication settings  SCL-slave: Nokeval SCL protocol  Modbus slave: Modbus RTU protocol BAUD Bit selection • 7E1, 8N1, 8E1, 8O1, 8N2 Note! SCL protocol uses always 8N1 and Modbus RTU uses commonly 8E1. ADDRESS Serial communications address selection. Valid SCL-addresses are 0...123. Valid Modbus RTU-addresses are 1...247 RESETTING SERIAL COMMUNICATION SETTINGS In case serial settings are for some reason not known, they can be reset by setting jumper in the position indicated by the following picture when the device is powered up. Settings will reset to...

MEKU MONITOR Meku monitor shows how many hours a device has been turned on, how many radio packets has been received, and shows the mean latency for serial communication. Also it shows 10 most recently received radio packets, which makes it easier to do configurations and find problems. Monitor shows device’s ID, type, signal intensity and also how long time since reception. Asterisk before line indicates the most recent packet. Signal strength -100dBm is just above noise and about -65 dBm is the maximum signal strength. At the bottom there are ”Error” lights, which indicate where exactly...

If the device is not required to use flash memory or packet buffers, flash and clock failures have no harm for device’s other operations. QUICK SETUP GUIDE FOR THE DEVICE RTR970PRO supports two different methods for saving normal periodic transmitter data packets to its flash memory: every packet separately or interval logging. Default setting is every packet separately. EVERY PACKET SEPARATELY If it’s ok to save all radio packets to flash memory, then the device works with PromoLog with default settings. Drawback of this approach is that every radio packet uses up flash memory and thus...

CHANNELS Device processes data in 3 different ways, one of which is channels. Device can handle 90 channels simultaneously. Channel is a real time data container, which consists of one fully processed wireless transmitter. Some transmitter types cannot be handled as channels. Every transmitter whose measurement result can be expressed as a single numeric value can be a channel. Following devices can be channels: MTR260, MTR262, MTR264, MTR265, MTR165, FTR860, CSR260. Following devices cannot be channels: CSR264, KMR260 Channel contains all available information of a transmitter: Value,...
