MODEL 50386R/D : Receiver/Decoder
General Description:
The HydroLynx Model 50386R/D Receiver/Decoder provides an intelligent decoder that
combines the effectiveness of the standard ALERT Receiver/Decoder with the utility
of the 50386. The Alert Receiver/Decoder receives ALERT data transmissions from the
remote site and provides an RS232 output to the central site computer. The 50386
Decoder features multiple communication pathways and the ability to process and re-format
data. This enables data sharing across various data collection systems.
As an intelligent decoder, the 50386D validates the data, in the formats that are
enabled, before processing the data for output. These formats include standard ALERT,
Enhanced IFLOWS, ASCII text, ScadaLynx and Modbus. As part of the processing, the
50386D has a programmable list of ID numbers to compare received reports ID numbers
and decide whether to output the data.
The Receiver and Decoder are housed in separate enclosures which allows the Receiver
to be located near the antenna tower and the Decoder to be placed at the central
site location. Locating the Receiver at the Antenna tower reduces the length of the
RF transmission line and the associated RF signal loss, and eliminates the potential
damage due to lightning entering the central site on the RF transmission line.
HydroLynx recommends the use of a high gain omni antenna at the central site receive
tower to increase radio path fade margins. Antenna and RF transmission line cables
are ordered separately (refer to the Antenna and Antenna Cable Sections). |
