IridiumLink 2-Way Logging Transmitter


IridiumLink 2-Way Logging Transmitter

    1. GUI setup program. 2. Terminal strip with screw terminals for I/O and power connections 3. Operates 8-16VDC — 12V recommended for SDI-12 sensors 4. TCXO real-time clock with battery backup (+/-4ppm) 5. Solar panel regulator for panels up to 30 watts. 6. Support for up to 16 measurements of the following inputs:

    • SDI-12/RS485 (shared as is done in the Sutron Bubbler)
    • 5 Analog inputs:
      •  Two (2) single ended inputs (range 0-5V)
      •  Two (2) differential inputs (range +/-39mv, +/-312mV, +/-2.5V)
      •  One (1) 4-20mA input
    •  2 digital inputs. They can be used for tipping bucket, frequency, and on/off inputs
    •  2 internal SPI for future expansion
    •  Internal temperature
    •  Battery voltage
    •  Meta measurement

    7. Options to average or accumulate 8. Lightning protection (Gas Tube) on all external inputs. 9. User specified equation on any measurement . 10. User specified alarm detection on any measurement. 11. 2 LED for verification/diagnostics. 12. Log capacity of 240K of data accessible via Iridium® and direct connect 13. Switched Battery Output 14. Also operates as a standalone recorder without telemetry 15. USB slave for connection to PC. THE USB PORT WILL NOT WORK with USB devices like memory sticks, modems, etc. 16. Real Time Clock operates with internal lifetime battery.
