2-Way RF technology
Provides enhanced system capabilities, such as those required for access control applications. Wireless
technology enables greater mobility, rapid deployment
and quick set-up.This reduces or eliminates installation
delays, provides lower total cost, less down time and
Programmable Digital & Analog Inputs/Outputs
-Six Inputs programmable as either Digital or Analog
-Two Analog Outputs configurable to 0-5V or 0-20mA
-Two Latching Relay Outputs that hold their
condition without power
The RTU's combination of flexible, programmable
inputs and outputs are designed to meet the needs of
the widest possible applications. Additional inputs and
outputs are obtained by connecting standard MODBUS
compatible I/O expansion devices to the Dataflow
RTU's Serial Communications port.
Reliable & Efflcient RF Communications Protocol
Over the air communications between RTUs use 1200
bps Manchester coded direct FM modulation with the
MODBUS protocol's inherent Error Detection and
Acknowledgment process.This modulation type combined
with the fully integrated radio provides effective
scan times faster than other systems that use FSK modems with voice grade radios.Qpical unit to unit
latency time is less than 1/2 second.
Field Programmable Options
A common serial programming interface configures both the R?ZT and synthesized plug-in radio transceiver module. This
allows for fast set-up and programming of the unit to customer requirements.
Digital Repeater Mode
Individual Dataflow RTUs can be programmed to function as repeaters giving the system greater range.
Micro-Power Operation -This feature enables Dataflow
RTUs to be placed at remote locations where
there is no source of power. In its lowest power mode,
with system integrity and update transmissions made several times an hour, the unit will run for 3-6 months on internal alkaline batteries.The same system will run indefinitely when the RTU is equipped with the integrated solar power option.
Versatile Power Supply Options
The Dataflow RTU can be powered in a variety of ways depending on the
requirements of the application
-Internal AA Alkaline or AA NiCad Battery Holder
-Internal NiCad Rechargeable Battery Pack
-Integrated Solar Panel/Charger
-External DC Power - By supplying an AC to DC
Power supply the unit can fe operated from
-AC with Battery Back-Up and Power Fail Message
Watertight Housing And Connectors
A water tight enclosure and connector system prevents dirt, dust or
moisture ingress.The Dataflow RTU is designed to perform without interruption even in harsh environments.
The Outputs of the Dataflow RTU can be programmed to revert to a
9600 bps. Fail-Safe condition if loss-of-signal occurs.
