Revision Sheet

 GENERAL

1.1 System Overview
The Data Gateway is the link between the edge devices in the Internet of Things (IoT) for agriculture and the cloud data server. 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 acknowledgment.

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

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 a location to send the location packet. IT MUST BE ABLE TO RECEIVE FROM GPS SATELLITES TO FUNCTION  CORRECTLY. After acquiring time and before the 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 the 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 a 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.

The RSSI LED indicator changes color to indicate cellular signal strength.

reception
Yellow| Poor signal strength
Green| Okay signal strength
Cyan| Good signal strength
---|---
White| 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 The 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 pointed 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 indicator to sync with the actual battery level (full charge). Care should be taken not to plug the Solar Panel connector into the Data Gateway upside down as this may damage the Data Gateway.

2.5| The Data Gateway easily attaches to a pivot pipe using molded-in magnets in the base of the enclosure. Slots in the Data Gateway base also allow for an additional zip tie to be utilized (recommended).|
2.6| Attach Solar Panel to the mounting bracket.|
2.7| RealmFive recommends installing in the first span, preferably NOT in the direct spray
from the pivot. While the Data Gateway is sealed, direct spray increases the risk of
water damage and mineral buildup on both the Data Gateway and the solar panel.
Sprinkler drops can be installed to avoid the direct spray.
Position the Data Gateway and Solar Panel on the pivot pipe within cable reach of each other. Ensure the connector on Data Gateway faces the solar panel.|
---|---|---
2.8| Use the supplied zip ties to secure the Solar Panel assembly and Data Gateway
to the pivot pipe. Tighten the zip ties enough to prevent the device from sliding sideways on the pipe. Avoid overtightening the zip tie on the Data Gateway as this may damage the enclosure.|
2.9| Plug the solar panel cable into the Data Gateway with the latch chip on the top side as shown. This will turn the Data Gateway on. The status LED will flash multi-colored when first turns on.
it will turn on its GPS receiver to acquire time and location. A short cyan blinks every two seconds indicates GPS is on.
It will also initiate a cellular connection and send a series of packets to verify functionality. See section Error! Reference source not found. for a description of the installation series. Solid green indicates it is connecting to a cell tower. 50% blinking green indicates it is communicating over cellular.
Immediately after booting, the Data Gateway will start listening for packets from end devices that are within range. A magenta->green blink indicates a radio packet was received.
Note that several statuses LED indications can go on at the same time.  The LED on the corner indicates RSSI. The installation should be relocated if this indicator stays red while connecting to cellular. Yellow indicates a poor signal. Green, cyan, or white are okay to excellent respectively.|
---|---|---
2.10| Once the Data Gateway completes the cellular connection, the Data Gateway’s app web page should show new data from the device
The signal strength number is the RSSI of the cellular connection. If the RSSI is less than -115, consider moving the Data Gateway installation higher or closer to a cell tower. On a pivot, the signal strength
will vary as the pivot rotates. With poor signal strength, this should be checked prior to leaving the installation site.
The timestamps on Location or Connectivity are in UTC. Tapping the timestamp will pop up the time since the last packet was received.
