How It Works Automatically synchronizes internal clock to GPS to maintain time accurate to 100mS. Measures sensors based on the user entered schedule. Applies slope, offset, or special calculation as needed. Stores the data in non-volatile flash memory. Transmits data at the user entered scheduled time or based on alarms. Maintains status and diagnostic information on measurements, transmissions.

LinkComm v3 – “Common Communicator” LinkComm can connect to SatLink3 via WiFi, RS232, or USB Setup the station View live reading View/download logged readings View diagnostics/status Calibrate sensors Works with ipad, iphone, Android, Windows XP, 7, 8, 10

Getting Started: Install LinkComm Android: Download/install from GooglePlay IOS: Download/install from iTunes Windows: Download/install from Sutron https://www.sutron.com/linkcomm-beta- software/ Or http://www.sutron.com/product/linkcomm/ If your PC is running windows 7, you will need to install the USB drivers after installing LinkComm. Note: this is not needed for Windows 8 and beyond.

Getting Started: Connect to Station If you are using WiFi, use your device settings to select the Satlink3 WiFi. The access point name will be Satlink3_stationname_xxxx otherwise, connect your USB cable to Satlink3 Note: RS232 will work but it is much slower than USB. Run LinkComm Select desired station on left or press + to create a new station. If creating a new station, enter the station name, and station type Select/Confirm Connect type and press Connect.

Working Disconnected vs. Connected Working disconnected from SatLink allows you to create or modify a complete setup in your office and then transfer the new setup to the SatLink on the next site visit This also works as a training tool to help you understand SatLink setups Working connected allows you to change setup, take measurements, troubleshoot and see data.

Benefits of SL3 with Iridium Communications Ability to Increase Frequency of Transmissions for Event-Monitoring - Use GOES most of the time then switch to IRIDIUM under alarm conditions - If alarms are triggered, SL3 collects & transmits more data more often Adds 2-Way Communication to Remote Stations Anywhere in the World - Remote User Access - Users have the ability to change the setup or configuration remotely - Improves Data Availability - Provides the ability to “ask” SL3 for data that may be missing to complete data records without gaps - Reduces Maintenance Costs - Reduction of a single field visit alone can cover the annual Iridium service cost for most stations Data Back-Up Using Redundant Transmissions & Communications - Transmit via GOES and Iridium   IRIDIUM Port on SL3

Overview of Telemetry via Iridium The Iridium® Global Satellite Constellation provides 2-way communications for remote stations anywhere in the world & delivers data how and when you want it. Since typical SBD messages range from 10 to 200 bytes, Iridium® is ideal for sending small amounts of data to and from extremely remote hydromet stations. Periodic transmissions at user set times with data in user selectable format (pseudobinary B, C, SHEF & ASCII) Transmission of alarm messages at the time they are triggered by an event Diagnostics to track amount of data being sent & performance of telemetry IRIDIUM® stations are Alert compatible via SutronWIN Supports remote data collection, maintenance or control of 2 on/off devices Optional authentication of incoming messages to ensure trusted source Sutron is an authorized IRIDIUM® Valued Added Reseller.

Python Programming What is Python? What are the benefits of Python? Python is a high level high-level programming language allowing users to write general purpose scripts to fulfill custom functionality. MicroPython is a light version of Python tailored for embedded microcontrollers systems such as the Sutron SatLink3, logging transmitter. For simplicity, this tech note refers to MicroPython simply as Python. What are the benefits of Python? Improved connectivity: Extends SatLink3 connectivity beyond standard sensor configurations and data formats. Customized behavior: Enables application specific behaviors such as event triggered sampling and adaptable transmissions. Community support: Leverages a powerful and popular scripting language, easy to learn with extensive support. Fast solutions: Customized solutions may now be crafted quickly and completely by the customer without waiting for added product functionality to be released.

Python Programming Use Cases: User defined custom measurement processing (ex: custom rating tables) Event triggered stand-alone scripts (on boot, on connect, scheduled time, alarm, etc..) Allows total of 8 individually configured script tasks, (ex: update an RS232 display on set schedule, change setup to measure and transmit more frequently) Custom transmit format – define and implement format to fit server requirements Custom support for RS485 or RS232 devices – easily overcome missing built-in support by creating interface plug-in for standard measurement or a script task Make quick changes or write short scripts directly in Linkcomm Integrated PyCharm editor for longer scripts or for support with built in SL3 functions Script storage space up to 1MByte RAM storage space of .5MByte available to hold a compiled script and variables LinkComm Python interface 

Python Programming What is PyCharm? LinkComm allows a user to connect to a SatLink3 device and to write and execute short scripts. For longer scripts, an Integrated Development Environment such as PyCharm may be used to edit, simulate, and debug scripts offline on a PC or it can run a script on the device. An advanced IDE such as PyCharm provides numerous productivity tools such as syntax checking, command completion, and context sensitive help.   PyCharm Editor
