The Data Gateway listens for data packets from edge devices and periodically makes a cellular data connection to forward the accumulated edge device packets to a server along with its own packets. The Data Gateway acknowledges packets from edge devices. The Data Gateway also holds downlink packets from the server for edge devices and sends them to the device after the next uplink packet from that device in lieu of an acknowledge. 1.2 Features The Data Gateway includes the following features:

Low power microcontroller Low power, long range radio for communication with edge devices Cellular data modem GPS receiver for device location Non-volatile memory for configurable settings Non-volatile memory for uplink and downlink packet queues Red-green-blue LED status and cellular RSSI indicators Accelerometer for user input Solar charged LiFePO4 41 W-Hr battery pack Powered by a 10 W Solar Panel Phone: 531-500-3817 RealmFive.com Page 4 of 14 3300 Folkways Circle Lincoln, NE 68504 Term API FCC GPS Hr ID IoT LED LiFePO4 QR RSS s URL UTC V W 1.3 Acronyms and Abbreviations Description Application Interface Federal Communications Commission Global Positioning System Hour Unique Identification Number Internet of Things Light Emitting Diode Lithium Iron Phosphate Quick Response Radio Standards Specification Seconds Universal Resource Locator Universal Time Coordinated Volts Watt 1.4 Important FCC and IC Compliance Information Changes or modifications not expressly approved by the manufacturer could void the users authority to operate this equipment.

Phone: 531-500-3817 RealmFive.com Page 5 of 14 3300 Folkways Circle Lincoln, NE 68504 1.6 Device Use Information 1.6.1 Enclosure The Data Gateway has a sealed enclosure. It should not be opened as this may damage the seal and void the warranty. 1.6.2 Installation Packet Series The Data Gateway will automatically send a series of four radio packets after it is powered up by connecting it to the solar panel. It sends a version packet, a status packet, a modem info packet, and a location packet. After booting it turns on its GPS receiver to acquire time and location. This is indicated with short cyan flashes every two seconds. It needs time to set its real time clock. It also needs location to send the location packet. IT MUST BE ABLE TO RECEIVE FROM GPS SATELLITES TO FUNCTION CORRECTLY. After acquiring time and before location is acquired, it wakes up its cell modem, connects to a local tower, and sends the version, status, and modem info packets. Solid green indicates it is connecting to a tower. Blinking green indicates it is transferring data to the server. After acquiring location, it sends the location packet and then goes to sleep. It keeps its radio on, in receive mode, while it is sleeping. When a radio packet is received it queues the packet and goes back to sleep. A magenta-green blink indicates it received a radio packet and sent an acknowledge. 1.6.3 User Input To achieve a long battery life, the Data Gateway sleeps most of the time. It will transmit data to the cloud via cellular connection every 15 minutes. It is set up to detect a double tap two taps, one immediately following the other. This will wake up the device if it is asleep. A white flash of the status indicator signals a double tap detection. This can be used to wake the Data Gateway and verify it is powered and running if it is sleeping. 1.6.4 Indicator Description The Data Gateway has two red-green-blue LED indicators: one for status (in the middle of the side) and one for cellular RSSI (toward the corner on the side). The table below gives the meaning of colors and flashes on the status LED. Color Green Yellow Cyan White Magenta-Green Green Green RBGRBG RYGY Flash Timing Meaning 0.1 s flash every 2 s Battery good 0.1 s flash every 2 s Battery low 0.1 s flash every 2 s GPS enabled Once Once On 0.5 s flash every 1 s Cellular connection made, transferring data Rapid and repeating Bootloader running Rapid and repeating Booting Firmware Double tap detected Radio packet received and sent acknowledge Attempting to connect to a cellular tower The RSSI LED indicator changes color to indicate cellular signal strength. Meaning Modem is sleeping or powered down Very poor signal strength relocate Data Gateway to improve cellular reception Poor signal strength Okay signal strength Color Off Red Yellow Green Phone: 531-500-3817 RealmFive.com Page 6 of 14 3300 Folkways Circle Lincoln, NE 68504 Cyan White Good signal strength Excellent signal strength 1.6.5 Orientation The bottom of the Data Gateway is V shaped and has magnets to aid in setting on a metal pipe. The Data Gateway may be installed horizontally or vertically. When installed horizontally the antenna should be set to a right angle with the antenna pointing up. When installed vertically the antenna and connector end should be on the bottom end. The antenna should be set straight and pointing down. 1.6.6 Data Gateway Power Connection Plugging the Solar Panel into the Data Gateway will power the Data Gateway up from its internal battery pack even if there is no sunlight to charge the battery. The Data Gateway can run through the night and through several heavily overcast days in a row when fully charged. It can be fully charged in less than one sunny day assuming the Solar Panel is oriented for good solar reception. However, due to battery shipping regulations, the Data Gateway ships with approximately 30% battery charge. It will need at least one full sun day for the battery level indication to sync with the actual battery level (full charge). Care should be taken not to plug the Solar Panel connector in to the Data Gateway upside down as this may damage the Data Gateway.
