The CDMALink provides simple telemetry anywhere. CDMALink has two purposes:
- To collect and store data from meteorological and hydrological sensors
- To send that data wirelessly to a central system, phone or other station.
CDMALink includes a quad band GSM cell phone modem that can operate when the unit is
within range of a cell phone network of companies like Sprint and Verizon.
Features:
- 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.
