Gateway - QSG Introduction This device complies with Part 15 of the FCC Rules. 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. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
Gateway - QSG MeshPlus® networks are used for remote monitoring and control of commercial, industrial, and municipal equipment such as utility infrastructure, municipal lighting, and traffic management. Hundreds of thousands of devices are currently being monitored and controlled by MeshPlus® networks. The MeshPlus® Gateway 3 – LAN Version (Gateway) is the central component of any MeshPlus® wide-area telemetry network. Each Gateway manages a mesh network and connects it to a local area network.
Gateway - QSG Quick Tour Let's examine the Gateway: The Gateway is contained in an 8.5” x 11” IP-65 rated hinged aluminum enclosure making it suitable for outdoor operation; all screws and metal components are aluminum or stainless-steel. The exterior is off-white powder-coat to resist weather and minimize thermal rise due to sunlight. The Gateway has the following connectors: 1. Mesh antenna connector: N-type 2. GPS antenna connector: SMA-type 3.
Gateway - QSG Open the Gateway by loosening the (four) 3mm hex bolts securing each corner. The bolts should be loosened until they have cleared the chassis but not removed from the top cover; they are captive so that they are not lost when the chassis is opened. Gateway Interior The internal components include: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
Gateway - QSG Mounting The Gateway is supplied with mounting hardware for structure or pole mounting. The installation tools required for the MeshPlus® Gateway installation are: • 3mm allen key • a 5/16-inch nut driver • 10 mm nut driver (deep well suggested) • open-ended wrench. The two mounting brackets are fastened to the back of the gateway chassis with stainless-steel bolts and may be used to mount the Gateway directly to a structure.
Gateway - QSG Power AC Mains Power The Gateway typically operates from mains power, either 110-120V AC or 220-240V AC 50Hz or 60Hz. The voltage selection (120 or 240vac) is a factory option and is indicated on the main board. An outdoor-rated (UV stabilized) AC cable connects power to the gateway through a waterproof cable gland. The AC cable must be connected to a grounded outlet. WARNING: failure to connect or bypassing the chassis ground can result in extremely dangerous conditions.
Gateway - QSG AC Cable Replacement To replace the AC cable: • Strip 1 ¾ ” of the outer jacket of the new AC power cord. • Strip 1/4” of the insulation from the end of each wire • Install the new AC power cable by reversing the steps above. Ensure that the hot, neutral, and ground connections are connected to the appropriate screw terminals. WARNING: Failure to connect the proper wire to the proper terminal will create a severe safety hazard.
Gateway - QSG AC Heater The Gateway includes an optional 20W or 40W AC-powered heater that operates automatically when temperatures fall below freezing (0C). The heater allows the SLA battery to charge when outside conditions fall below freezing, helps prevent condensation from forming inside the Gateway, and allows the Gateway to operate below its rated minimum voltage (-40C).
Gateway - QSG DC Power Requirements The Gateway typically consumes less than 3W of power with maximum DC power consumption of 15W. The minimum input voltage is 12v for proper operation of the Gateway SLA charger. If the SLA backup battery is not required, lower input voltages may be used with a minimum external input voltage of 8v.
Gateway - QSG Sealed Lead-Acid Backup Battery The Gateway is designed to continue operating during power outages. A 6v 4.5AH sealed lead-acid (SLA) battery (7) provides full power for 12-24 hours during power outages. Blackouts longer than this are very rare in the United States.
Gateway - QSG To replace the SLA battery: • unplug the battery connector • loosen the 3 bracket bolts shown in the diagram to the right (do not remove the bolts; they are captive to the bracket) • disconnect the wiring harness from the old SLA battery • connect the wiring harness to the new battery paying careful attention to the polarity: the red wire goes to the positive battery terminal and the black wire goes to the negative battery terminal.
Gateway - QSG The Lithium battery is installed in aluminum battery holder B1 with the positive terminal facing up as shown. If the battery is inserted incorrectly, the battery is automatically disconnected from the GW3 circuitry for safety and the red reverse-polarity indicator LED will illuminate.
Gateway - QSG GPS Antenna Connection The Gateway requires an active (amplified) GPS antenna connected via SMA connector (10). The Gateway has an integrated GPS receiver which receives signals from the GPS satellites and automatically determines the gateway's location and the current time of day with great precision. An external GPS antenna should be attached to connector 10; the GPS antenna should be positioned such that it has a clear view of the sky.
Gateway - QSG complex antenna analyzers during installation and allows remove and continuous monitoring of the antenna during operation. If the antenna or the coaxial feed-line are damaged, the Gateway will detect the condition and issue an alarm. The coaxial cable connecting the antenna to the gateway should have low loss at 902-928MHz. Only high quality cable such as LMR400 should be used.
Gateway - QSG Network Connection The gateway requires a 10/100 Base TX Ethernet connection to a TCP/IP network. The MeshMaster data collection software uses this connection to remotely manage the Gateway and to retrieve data the Gateway has received and stored from the wireless mesh. The Gateway Network Interface is connected to the chassis exterior via a short cable and a waterproof RJ-45 Ethernet connector.
