1. Introduction
1.1 Product overview
MX190x is an outdoor LPWAN gateway equipped with dual LoRa radio capable of simultaneously
receive on 16 frequency channels. It is based on the newest SX1302 LoRaWAN Gateway chip which
allows it to use spreading factors from SF5 to SF12. This greatly improves the throughput and
decreases the data collisions in dense networks with many sensor nodes compared with previous
generation of gateways based on older SX1301. Improvement on performance comes together with
significant reduction of power consumption which reduces the cost of operation and increases long
time reliability of the devices.
This guide covers the MX1901 and MX1902 version of MatchX M2 Pro Gateway, with the
MatchX LPWAN controller version 1.0 or above. The main differences between them are listed in

2. 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/
2.1 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.
2.2 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

10 Chapter 2. Quick Installation Guide
2.3 Power connection
The Gateway offers two ways of supplying power:
•Passive 24V DC PoE
•USB-C
2.3.1 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.
Figure 2.1: Connection of MX1901/2 Gateway.
2.3.2 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.

2.4 Accessing the Gateway and Internet connection 11
!
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.
2.4 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) or WiFi. For 3G/4G connection option please contact MatchX support or sales department.
2.4.1 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.
2.4.2 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.
2.5 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.
2.5.1 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.

12 Chapter 2. Quick Installation Guide
• 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.

Figure 2.3: Mounting the MX1901/2 Gateway to the pole.

2.6 Surge protection and Shielded Ethernet cable 13
2.5.2 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.
2.6 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.
