TELEMETRY EQUIPMENT

MODEL 50388
Real-Time Data Transmitter
ALERT2/SCADA Two-Way Transmitter

General Description

The Model 50388 Real-time Data Transmitter collects, processes, and transmits analog, digital, and serial sensor data on events and timed intervals. The collection, processing, and transmission of sensor data is controlled by parameters that are programmed using the ScadaLynx Toolbox software. The sensor data can be transmitted using multiple communication paths with mixed formats and protocols.

The HydroLynx Model 50388 ScadaLynx uses dual processor architecture and the latest in embedded processor technology to minimize power usage when idle and maximize computational power and performance when awake. The main processor runs the main data collection, data telemetry, and control processes. The second low power processor collects digital status and counter data. When the main processor is idle, it is put to sleep to conserve power. The PIC I/O processor wakes up the main processor on timed intervals, when digital event thresholds are met, radio carrier is detected, or data is entered on the console communication port.

All 50388 power lines use blade fuses for easy replacement. All power and I/O lines are protected against over voltage, short, and reverse polarity.

Standard memory on the Model 50388 consists of FLASH, Battery backed SRAM, and a battery-backed Real-time Clock (RTC). 16 MB of nonvolatile FLASH is provided for program and configuration file storage and data logging. Although stored in FLASH, the program is copied into battery backed SRAM (256 KB) for faster execution. A micro SD card up to 16 GB is provided for data logging and file storage. The contents of nonvolatile and battery-backed memory are not lost when power is removed.

The Model 50388 Data Transmitter is programmed using a Windows based ScadaLynx Toolbox software package. Transmitter programming can be done directly using the USB-B programming port or any of the four RS232 serial ports or remotely through telemetry equipment connected to these ports. The programming parameters include station identification; sensor I/O identification, scaling, sampling, computations, logging threshold, reporting threshold; alarm or control actions; communication parameters; power down settings; clock time and time zone; and data logging format and limit.

The Model 50388 Data Transmitter supports up to 16 analog inputs, 16 bit Analog to Digital converter, 8 programmable gains for ranges from 25 mV to 5VDC, 16 digital status inputs, 4 low speed up/down counter inputs, 4 high speed up only counter inputs, 8 digital outputs, and 5 SDI-12 connections. Serial data collection is possible through one or more RS232 serial ports.

Virtual sensor data can be computed from sensor inputs to compute sensor averages, maximums, minimums and runtimes. Virtual sensor data can then be tested, alarmed, logged and transmitted just like actual sensor inputs.

Eight digital outputs allow the 50388 Data Transmitter to perform local controls based on sensor upper, lower and change limits. Control resets are based on reset value and time interval limits.

Four RS232 serial ports are available for one or two-way communication or serial sensors. Communication formats include ALERT2 HDR, ScadaLynx, ASCII, and MODBUS. Communication paths can be through ALERT2 radio transceivers; SCADA radio transceivers; WIFI, GOES transmitter; direct serial connections.

One USB-A port is provided for file copies, one USB-B port is provided for programming with the ScadaLynx Toolbox, one Ethernet port is provided for TCP/IP data transfers, one micro SD card is provided for data logging.

Packaging for the Model 50388 includes the standard ALERT style canister, Metal panel mount, Rack mount, NEMA-4X fiberglass enclosure.
