What does it do?
The A850 Telemetry Gateway is the central device through which you configure all your RTUs. It is here that you connect sensor drivers and insert sensor calibration info, establish polling routes, set polling time tables, analyse communication quality, connection regularity, data delays, and much more.
Through the Gateway you can bidirectionally communicate with all your RTUs and change their parameters at any given time - without having to go into the field - you do it all through the Gateway!
Which RTUs can be connected?
An A850 Base Station, which includes a UHF modem, supports all kinds of ADCON RTUs currently available: short and long range UHF radios, GSM, GPRS and UMTS RTUs. It also supports the RA440 Remote Wireless Modem, to which the A850 can connect by GPRS in order to then retrieve data from UHF stations.
The basic version of an A850 supports 5 RTUs, but can be upgraded to support 100 - 250 - 500 - 1.000
Adding further Wireless Modems:
By default an A850 supports two wireless modems. It can be upgraded to support up to 10 wireless modems, of which one can be an A440.
An A850 Telemetry Gateway is handling up to 1.000 Adcon RTU's, no matter if they are long range or short range UHF units, GSM or GPRS RTU's. The A850 Telemetry Gateway knows the route to each radio RTU, the phone number of each GSM unit and the IP address of a GPRS RTU. It also knows exactly when and how often to poll data from each RTU. Changes to routes, phone numbers and polling intervals are programmed centrally in the Gateway, NOT the RTU!
It is crucial to know which equipment is installed in the field, where exactly it is located, which serial numbers it has, which battery type it contains, when it was last serviced etc. All these parameters are now stored in the A850. For the Network Administrator it is also crucial to be able to properly diagnose a system in order to recognize weak spots before they cause trouble. The A850 Telemetry Gateway will let him assess battery voltage, internal temperature, uptime of the RTU, firmware versions and many other parameters.
The A850 Telemetry Gateway provides a wide range of sensor drivers for almost any parameter around, be it an analog or an SDI-12 sensor. In it's largest version an A850 will be capable of handling up to 10.000 sensors in a single network! Custom drivers can easily be created and stored. Proper driver assignment to the respective RTU port, data interpretation, sensor calibration and maintenance info are all handled by the A850 Telemetry Gateway.
Integrated Data Visualization
This unique feature will enable you to directly open a trend panel in the A850's Configurator! Visualize sensor and diagnostical data with a mouse click - and assess any kind of data in graphical or table format right in the Gateway, without the need to download the data into another software package, not even addVANTAGE Pro 5! This feature is particularly handy for industrial clients, who use their own SCADA software, but have difficulties to create new views and trends for diagnostical data.
Autonomous Operation - Large Data Buffer and integrated UPS
Imagine a large network of 500 ETo stations. Imagine every station delivering 100 data sets per day. An A850 Telemetry Gateway will be able to store all that data for almost 2 weeks!
And if a lightning will cause several hours of blackout, the internal battery pack of the A850 will be able to maintain the unit operational.
Data can be retrieved from the A850 through its 100 MBit Ethernet connector, or an external modem connected to a USB or RS-232 port. In most cases the A850 will be part of a clients Intranet. But it can basically be installed anywhere, even in the remotest of areas, as long as there is a mains connection, and a phone line or GSM coverage. addVANTAGE Pro will automatically retrieve the data from this remote Gateway.
The A850 Telemetry Gateway communicates via a 30m RS-485 cable with the roof mounted A440 Wireless Modem. For very large buildings or installations on a high mast an optional 75m low-attenuation cable can be supplied. The A440 Wireless Modem comes in an IP67 rated case and is compatible with all Adcon RTU's sold to this day.
The A850 Telemetry Gateway is prepared for future firmware upgrades, that will enable it to run up to ten external USB modems, and to operate several Wireless Modems on different frequencies. That means that your A850 will be capable to run a network of 450MHz RTU's AND at the same time a network of 868 resp. 902 MHz RTU's.
