Page 1 of 9 LTE Gateway Gateway User Manual Title: Gateway User Manual Author: Chris Hack Rev: B Date: 1/31/17 NOTICE: This device complies with Part 15 of the FCC Rules [and with Industry Canada licence-exempt RSS standard(s)]. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Antenna Statement Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Page 2 of 9 LTE Gateway Gateway User Manual Licence exempt This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. RF Exposure This equipment complies with FCC and IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with the minimum distance 20cm between the radiator & human body. This radio transmitter IC: 6872A-0421GWBH has been approved by Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device. Skywave LTE Fle Antena 15-8324-B 704~960 MHz / 1710~2155MHz VSWR ≤ 3.0 2.1 dBi Gain (nominal) Page 3 of 9 LTE Gateway Gateway User Manual The Gateway is battery powered transmitter that will be positioned outdoors to relay logs from meters in the field back to the cloud, so that the logs can be viewed and analyzed. This manual describes the basic start up for the Gateway in Debug mode to make sure everything is working correctly. Initial startup and boot sequence: First, plug the unit into the battery back, as shown in figure 1. The LCD should remain off, as shown in Figure 2. Figure 1 Figure 2 Next press the “Select” button. The LCD should say “Read SD” and then enter the Boot Menu, as shown in Figure 3. If it becomes necessary to clear a Gateway’s memory, or if the Gateway has been relocated, “Reset” should be pressed, and the instructions followed until this step (the Gateway’s LCD displays the Boot Menu prompt). Further steps are unnecessary if unneeded. If first installing the Gateway and a test of the location’s viability are desired, next press either the “Enter” or “Select” button to view the menu options. To cycle through the menu options, press “Select” and to choose a menu option, press “Enter.” Press “Enter” to select the “Boot Gateway” option when the arrow points to that option, as shown in Figure 4. Figure 3 Figure 4 The Gateway will now boot, acquiring both the local time from the cellular network and the GPS location. The Gateway will display the current operation in progress on the LCD screen, as shown in Figures 5 and 6. Figure 5 Figure 6 Page 4 of 9 LTE Gateway Gateway User Manual Once the boot process is complete, the Gateway will enter the Debug Menu, displayed in Figure 7 below. In order to cycle through the menu options, press the “Select” button. After the usage instructions, the first selectable menu option is “Listen Now.” This option initiates a two minute scan cycle where the Gateway listens for any meters it can hear and stores the data. Figure 8 displays the “Listen Now” menu option. Pressing “Enter” will select the menu option. Selecting “Listen Now” will cause the Gateway to immediately listen for any meters it can hear in the vicinity for two minutes (default) and display the number of meters found on the LCD (Figure 9). Upon completion, the LCD will display “Complete” followed by the number of meters found in the scan and then the overall number of meters stored in the Gateway’s memory. Figure 7 Figure 8 Figure 9 The second option that should be selected when installing a Gateway is the “Send EP Data” option, shown below in Figure 10. This sends the information gathered from the scan cycle to the cloud. Using this data, the user can view the meters read by the Gateway on a map in Waterscope to ensure that the current Gateway location is optimal. Figure 10 Debug Menu Options: In order to verify th…
