Lora
The MatchX M2 Pro fully supports LoRaWAN protocol, covering a massive vicinity of up to 20km+ in open spaces. Thanks to 16 frequencies channels and Spreading Factors as low as SF5 this gateway provides exceptionally good coverage in places with huge number of sensor devices. Based on the newest LoRa chipset SX1302 the Gateway is able to simultaneously demodulated more data packets then it was possible before reducing data collision and allowing for more dense sensor deployment in applications like smart farming, home automation or asset tracking.

WiFi
The MX1901/2 Gateways provide build in WiFi connectivity according to 2.4GHz 802.11b/g/n specification. Thanks to build in antenna no extra installation is needed. WiFi connection can be used to provide internet connection to the Gateway or to access the Web UI configuration page to manage the Gateway. If WiFi connection is not needed it can be disabled to save power.

GPS
The Gateway is equipped with Ublox MAX-7Q GNSS receiver with additional LNA to improve sensitivity and lower time to fix. The GNSS is not only used for location finding of the Gateway but also for time synchronization and precise time stamping of the received LoRa packets.

Processor Subsystem
MatchX M2 Pro gateways are based on the industry-standard i.MX6 MCIMX6G2CVM05AB processor from NXP equipped with 256MB of DDR3 RAM and 256MB of Flash memory and it is rated for extended temperature range. The low power consumption, high reliability and security options make this processor ideal for industrial application where those features are at most important.

Quick Installation Guide

The MX1901/2 Gateway is preconfigured “Plug ’n Play” device, which mean installation is extremely easy. At first power up the Gateway will connect to MatchX network without any need of setup. This installation guide will guide through process of configuring the Gateway and it’s LoRa parameters. Every Gateway comes with a unique serial number and QR code placed under the cover of cable compartment. Ether of them can be used for setting up the GW on the Cloud server. The list and links to the Cloud servers can be found on MatchX website under https://www.matchx.io/

Software requirements
To use the MatchX M2 Pro Gateway no special software is required, as the Gateway is preconfigured to connect to the MatchX Cloud server. To access the Cloud Server a computer or mobile devices with a web browser such as Chrome or Firefox is sufficient. To make the installation easy it is possible to use a mobile device with QR code reader for easy registration on the chosen Cloud Server.

Hardware requirements
The hardware of the MatchX M2 Pro Gateway is design in such a way that it needs minimum number of external components to make it functional. The user has few different connection options he/she can choose from to make the installation easy and convenient. Depending on the installation option (described in next sections) the following components can be needed:

• PC computer or Mobile device
• Ethernet cable
• USB-C cable
• Access to AC power outlet
• WiFi router or Ethernet switch
• Screw driver and similar tools

Power connection

The Gateway offers two ways of supplying power:

• Passive 24V DC PoE
• USB-C

PoE power supply
On Figure 2.1 the PoE connection is illustrated. The injector has two RJ45 connectors marked as POE and LAN. It is important to pay attention to correct connection of this connectors:

• POE connector needs to be connected with Ethernet cable to the RJ45 connector of the Gateway.
• LAN connector needs to be connected with Ethernet cable to Internet router or switch.
  The PoE injector needs to connected to 230/110V AC power outlet.

USB-C power supply
MX1901/2 Gateways can be powered from USB-C connector. It does implement USB PD rev 2.0 and is interoperable with USB PD rev 3.0 standard up to 22V. It is recommended to use a dedicated USB-C power supply which implements USB PD standard and has enough power capability. Powering the Gateway from USB port of PC or similar is not recommended because of limited current capabilities of those ports.

Accessing the Gateway and Internet connection

The Gateway needs internet connection in order to communicate with LoRaWAN server such as MatchX Cloud Server. There are two primary ways to provide such connection: Ethernet cable (preferred) orWiFi. For 3G/4G connection option please contact MatchX support or sales department.

Ethernet connection
Ethernet cable is a preferred way of connecting because it provides more reliable internet access and the same cable can be used to deliver 24V DC power to the Gateway. The PoE injector power supply is included together with Gateway so the user doesn’t need to spend time searching for compatible model. The connection between Gateway, PoE injector and Internet router should look like the one depicted on Figure 2.1.
After power up the Gateway should automatically get IP address assigned by the DHCP server usually running in the network. To find out the assigned IP address user can login to the router and see the list of assigned IP addresses or scan the entire local network using any available software tool like AngryIP, the gateway will appear with its serial number as hostname. After obtaining the IP address it can be used directly in the web browser like Chrome or Firefox to get access to Gateways web configuration interface if needed. If gateways autoconfiguration process was successful and internet access is available the LED should turn steady green.

WiFi connection
The WiFi interface of the Gateway works in Access Point mode by default. The SSID of the network generated by the device has a general format of: MatchX_MX190x_yyyy, where: yyyy – 4 last bytes of MAC address. The default password of the WiFi network is the serial number of the Gateway. After connecting to the network IP address will be automatically assigned to the PC or mobile device. The Web User Interface of the Gateway can be accessed by its IP address (192.168.0.1).From the Web Interface it is possible to configure the Gateway to connect to other WiFi network and use it for internet connection. In this case there is no need to connecting a Ethernet cable between LAN port of the PoE injector and Internet router.

3G/4G/LTE Option
The MatchX M2 Pro supports a optional 3G/4G/LTE modem installed inside of the gateway. MatchX offers a globally certified LTE Cat 1 module optimized for M2M and IoT applications with a worldwide LTE, UMTS/HSPA(+) and GSM/GPRS/EDGE coverage. The antenna port 3 (marked “A” on the enclosure, see Fig. 1.2) is used to connect the LTE antenna. For further information and installation guide contact MatchX or visit the WWW.MATCHX.IO website.

Mounting

This device must be professionally installed by qualified person. The Gateway is IP67 rated and can be mounted outside in vertical position. Vertical position is crucial to ensure the environmental resistance of the Gateway. Keep in mind that PoE power injector is not waterproof and has to be additionally protected if it is to be placed outside.

Wall Mounting
The screws and screw anchors are included in the package, users can drill two 6mm hole on the wall and apply screw anchors to them.

• Determine the place of mount, it should be an even surface.
• Mark two holes that are going to be drilled, the distance between them. should be 54mm, and they should be horizontally aligned .
• Drill two 6mm hole, apply screw anchors and screws.
• Adjust the screw spacing.
• Push the screws heads through the larger opening hole of the Gateways fixture and then pull the Gateway down so the screws get locked in position.

Pole mounting
The Gateway can be easily connected to a pole using a stainless steel clamp included in the box. The Gateways fixture is specially designed to fit to poles curvature. To make the mounting even more stable it is a good idea to use two clamps spaced as far apart as possible.

• Determine the place of mount, we recommend a round pole
• Position the Gateway on desired place, and fasten the stainless steel clamp.
• Tighten the screw of the clamp enough to make the mounting stable but not to much to brake the plastic fixture of the Gateway.

Surge protection and Shielded Ethernet cable
We highly recommend to use the shielded RJ45 cable to connect the Box, in order to protect the device from any possible lightning or electricity surges. Both shielded FTP and S-FTP cable from Cat5e are recommended. To protect the Gateway and Ethenet equpiment connected to it we highly recomend using lightning and surge protectors near the Gateway and near the PoE.
