1ABOUT THIS GUIDE
This document is the parent guide of the RG1xx Quick Start Guide and provides a comprehensive guide on
how to configure the Sentrius RG186 and RG191 gateways to suit the intended application. It covers all the
Sentrius RG1xx functionality, including Ethernet, Wi-Fi and LoRa configurations. It also provides instructions
for setting up the gateway on a LoRa network server.
Note: Step-by-step instruction, screen shots, and pictures are based on the Sentrius RG191, but the
same is applicable for the Sentrius RG186; differences are highlighted in the notes.
2INTRODUCTION
2.1 Product Overview
Laird’s Sentrius™ RG1xx LoRa-Enabled Gateway is the ultimate in secure,
scalable, robust LoRa solutions for end-to-end control of your private
LoRaWAN network. Leveraging Laird’s field-proven and reliable 50 Series
Wireless Bridge certified module, it also offers enterprise dual-band Wi-Fi, BT
v4.0 (BLE and Classic), and wired Ethernet for complete design freedom. Based
on the Semtech SX1301/SX1257 chipset designs, it offers a LoRa range up to
ten miles and pre-loaded LoRa Packet Forwarder software, perfect for highly
scalable, flexible IoT networks. The Sentrius RG1xx Gateway works with
Laird’s Sentrius RM1xx Series LoRa+BLE certified modules for simple out-of-
the-box integration and is compatible with third-party cloud and LoRa partners,
as well as any LoRaWAN-certified client devices.

3CONNECTING THE HARDWARE
3.1 Connect the Gateway
To use the gateway, you must power up the gateway and access the web interface via the Ethernet port. To
do this, follow these steps:
1. Follow the label on the box and connect the three antennas. Refer to Antenna Configuration for
additional information.
2. Connect the power supply (see #2 in Figure 3).
3. Connect the gateway to your router (#3 in Figure 3) using the Ethernet cable (#1 in Figure 3).
Alternatively use the Wi-Fi Quick Config mechanism. Refer to Wi-Fi Quick Config for additional
information.
Your gateway is now connected and ready.
Figure 3: Connecting the gateway
3.1.1 Antenna Configuration
To configure the antenna properly, do the following:
1. Attach the two shorter antennas to the 2.4/5.5 GHz (Wi-Fi) ports.
2. Attach the third and longer antenna to the 868 MHz/900 MHz (LoRa) port.

3.1.2 Wi-Fi Quick Configuration
The gateway includes a mode to allow you to configure without ethernet access, in the case that you wish to
join a wireless network.
Apply power to the gateway and allow to start, then perform the following:
1. Depress and hold the user button (see #2 in Figure 2) for seven seconds.
2. From a wirelessly enabled device perform a scan.
3. Connect to the access point rg1xx29378B, where “29378B” are the last six digits of the Ethernet MAC
address found on the label on the bottom of the gateway (Figure 4).
The network is secured with WPA2 with a password that is the same as the SSID. We recommend that
you change the default password for security reasons. The password can be changed on the
Wi-Fi > Advanced web page.
Upon logout or client disassociation, Wi-Fi Quick Config shuts down and normal operation resumes.
4LOG INTO THE GATEWAY
To log into the gateway web interface, follow these steps:
1. Determine the last three bytes of your gateway’s Ethernet MAC address. This can be found on the label
on the bottom of the gateway; the last three bytes are highlighted (Figure 4).
Figure 4: Bottom label –last three bytes of the Ethernet MAC address highlighted
2. Enter the URL into the web browser to access the web interface. For example, for the gateway used in
this guide, the URL is https://rg1xx29378B.local., where “29378B” are the last six digits of the Ethernet
MAC address. In Wi-Fi quick config mode, the gateway can also be accessed via the IP address at
https://192.168.1.1
3. Accept the self-signed security certificate in the browser.
4. Click Advanced (Figure 5).

5LAN CONNECTION SETUP
The LAN menu allows selections for configuration and status of the IPv4/IPv6 wired network. The current
status of the IPv4 network is also displayed. To access this section, click LAN in the page menu.
5.1 IPv4 Configuration
The first page for configuring the Ethernet LAN connection is the IPv4 Configuration page. There are two basic
modes of operation –DHCP and Static. These are selected in the IP Address Acquisition Method drop-down
box (Figure 10). The gateway factory default setting is DHCP.
Figure 10: IPv4 Configuration page
▪DHCP –When in DHCP mode, all settings are provided by the DHCP server. All configuration settings
(except IP Address Acquisition Method) are greyed out. IP values provided by DHCP are displayed but
cannot be changed.
▪Static –When the IP Address Acquisition Method is set to static, all IP settings are fixed and saved in the
device. The external Gateway IP address is optional and may be left blank. DNS Server IP addresses are
also optional. Zero, one, or two DNS servers may be specified.
5.2 IPv6 Configuration
Select the IPv6 configuration by clicking the IPv6 menu item in the side menu of the LAN view (Figure 10). The
IPv6 configuration settings are shown below.
There are two fully-supported modes for IPv6 addressing:
▪DHCP –In DHCP mode, all settings are provided through communication with an IPv6 server on the
network.
▪Auto –In auto mode, you have the option of selecting the auto DHCP method (either stateless or
SLAAC). As of June 2017, IPv6 static mode is only partially supported. Please see the software release
notes for current information.

6WI-FI CONNECTION SETUP
By default, the gateway’s Wi-Fi radio is not configured to connect to a Wi-Fi network. The user must access
the web interface on the gateway via the Ethernet interface to setup the Wi-Fi connection.
To setup a Wi-Fi connection, click the Wi-Fi tab in the main menu (Figure 13).
Figure 13: Wi-Fi connection setup
In the sidebar on the left, you can navigate to various Wi-Fi pages and see the status of the Wi-Fi interface.
There is also a button to enable/disable the Wi-Fi radio.
6.1 Use Scan to Add a Profile
To use the scan function to add a profile, follow these steps:
Connect to a Wi-Fi network –click Scan to scan for nearby Wi-Fi networks. Scanning continues until
you click Stop or click on one of the listed scan results (Figure 14).

7LORA CONNECTION SETUP
The side panel for the LoRa Gateway allows selections for configuration and status of the LoRa network card.
The status of the LoRa Network is also displayed (Figure 19).
Figure 19: LoRa connection setup page
The Gateway ID (also known as the gateway EUI), is used to uniquely identify the RG1xx gateway. It is
required when registering the gateway on a LoRa network server. The gateway EUI is also printed on the
bottom label of the gateway, with the label M2 EUI.
Figure 20: Gateway label
7.1 Using Presets
The Sentrius RG1xx contains multiple preset configurations for connecting to a third-party server or as the
basis for a private network. These presets configure the forwarder and the channel plan.
To apply a preset configuration, follow these steps:
Click the LoRa tab in the main menu. The default page of the LoRa menu is the Presets page (also
accessible in the left side menu of the LoRa pages).
Select the preset from the drop down. Information about this preset is displayed in a panel to the right
(Figure 21).
Click Apply to apply the preset configuration. After a few moments, a green confirmation appears on
the bottom of the page.
Note: The LoRa Region Code is
displayed here. Be sure
that the gateway you are
operating matches the
region in which you are
operating it.

7.3 Radios
The radio page provides configuration of the radios and channels. The LoRa card has two radios (Radio 0 and
Radio 1). This interface allows advanced users to change radio and channel assignments within the allowed
range per the gateway region. Depending on the forwarder being used, the radio configuration may not be
available.
7.3.1 Channel Plan Graphic
At the top of the Radios page is a graphic representation of the full bandwidth range, channels, and radios.
This graphic is different for gateways operating in US mode and EU mode.
7.3.2 Radio Center Frequencies
Each radio is assigned a center frequency. Channels are then assigned to each radio and given an offset from
the center (Figure 23).
Figure 23: Channel assignments
7.3.3 Channels
Channels are enabled and assigned to either radio. Each radio can have up to five channels assigned to it.
The channel’s frequency is an offset of its radio’s center frequency. For most channels with a 125-kHz
bandwidth, the offset can be -0.4 to +0.4 MHz.
Lora STD and FSK channels have configurable bandwidth. For these channels, when operating in 250-kHz or
500-kHz bandwidth, the offset can be -0.3 to +0.3 MHz.
