CDMALink 2-Way Logging Transmitter

    • Easy-to-use Software includes setup program.
    • Terminal strip with screw terminals for I/O and power connections
    • Operates 8-16VDC
    • TCXO real-time clock with battery backup (+/-4ppm)
    • Built-in solar panel regulator
    • Support for up to 16 measurements of the following inputs: • SDI-12/RS485 (shared as is done in the Bubbler) • 5 Analog inputs: 1. Two (2) single ended inputs (range 0-5V) 2. Two (2) differential inputs (range +/-39mv, +/-312mV, +/-2.5V) 3. One (1) 4-20mA input • 2 digital inputs. They can be used for tipping bucket, frequency, andon/off inputs • internal temperature • Battery voltage
    • Options to average or accumulate any measurement.
    • Lightning protection (Gas Tube) on all external inputs.
    • User specified equation on any measurement .
    • User specified alarm detection on any measurement.
    • 2 LED for verification/diagnostics.
    • Log capacity of 240K of data accessible via CDMA and direct connect
    • Switched Battery Output
    • Also operates as a standalone recorder without Telemetry
    • USB slave for serial connection to PC. THE USB PORT WILL NOT SUPPORT typical USB devices like memory sticks, modems, etc.
    • RealTime Clock operates with internal lifetime battery
    • Telemetry via CDMA
    • 1. Periodic transmissions at user set times with data in user selectable format (pseudobinary B, C, SHEF & ASCII)
    • 2. Support for primary and secondary master stations via CDMA
    • 3. Alarm transmissions as they are detected.
    • 4. Diagnostics to help track of the amount of data being sent and the performance of the telemetry
    • 5. Support for remote commands for data collection, maintenance or control of two on/off devices
    • 6. Optional authentication of incoming messages to insure they are from a trusted source & optional authentication of messages sent to SUTRONWIN via CDMA
    • 7. SMS transmissions if CDMA fails or in place of CDMA
    • 8. Extremely affordable
    • 9. CDMA modems use wireless cellular technology and provide data access in most areas where a typical cell phone works.
    • Surface waterlevel,flow and quality
    • Groundwaterlevel and quality
    • Offshore X‐Linking
    • Mining / geotechnical
    • Weather X‐Linking and warning
    • Oceanic X‐Linking and warning
    • Oil and gas production
    • Any low‐power,remote data acquisition system
