Multiband-OEM User Guide (OEM Form Factor)

Overview

The Multiband-OEM Mesh Rider radio is a small, rugged, light-weight IP-based OEM radio designed for military, law-enforcement, and emergency services personnel. With cutting-edge technology and rugged durability, this radio is designed to deliver reliable, secure, and uninterrupted communication in the most challenging environments.

The Multiband-OEM radio employs Doodle Labs' patented Mesh Rider® technology with state-of-the-art RF and networking capabilities that enable communication further, faster, and more reliably than any comparable solution on the market. Devices can connect to the Multiband-OEM radio over the USB, Ethernet or Wi-Fi interfaces.

This user guide details the main features of the radio, and walks you through the setup and usage of the radio.

Factory Reset

Factory Reset over hardware can only be achieved using the HID interface board.

To factory reset, hold down both the Turbo button and the Power button until the indicators all start flashing. After that, release the two buttons and wait for the device to reboot. A factory reset may take up to 5 minutes. Do not power down the unit during the factory reset.

Initial Setup

Hardware setup

Connect the HID interface board, and the EVK board to the Multiband OEM radio following the guidelines above, along with the antennas provided in your evaluation kit.

• As soon as power is applied to the radios, all of the LEDs will blink once.
• After powering the radio, hold down the Power button for 2 seconds to turn the unit on. The Power LED will blink until the unit has fully booted, at which point it will be steady.
• While booting up, both the Wi-Fi and Mesh Rider indicators will blink. They will switch to a slow blink after boot-up while waiting for a connection. If you have turned on any other radio, the Mesh Rider indicator will eventually hold steady once the radios are connected.
• If you connect to the radio over it's Wi-Fi interface, then the Wi-Fi indicator will hold steady.

Connecting to the OEM

The EVK board uses standard wiring to suppport the Ethernet, USB-Host, and USB-Device interfaces. Both the USB-Host and USB-Device ports support USB 2.0.

Wi-Fi Connection

You can connect to the radio over it's built-in Wi-Fi radio. By default, the built-in Wi-Fi radio starts up an Access Point with SSID DoodleLabsWiFi-<last 6 hex digits of MAC> and password DoodleSmartRadio. Remember to connect the Wi-Fi antenna to the Multiband OEM Radio.

See the Software Setup section for details on IP addressing.

USB Connection (OEM as USB Device)

Alternatively, you can connect to the radio over the USB port on the EVK. You can connect to the radio's USB port from a PC or a smart device (e.g. tablet or phone) which supports USB reverse tethering. In this mode, the OEM is a USB Device, and the PC/tablet/phone is a USB Host.

See the Software Setup section for details on IP addressing.

Ethernet Connection

The EVK board provides a standard RJ45 Jack for Ethernet.

See the Software Setup section for details on IP addressing.

USB Connection (OEM as USB Host)

As a final alternative, you can use the Multiband OEM radio's USB-Host port to connect to a USB Device such as an Android Smart Phone with a USB OTG port. Doodle Labs does not provide a USB dongle for this purpose, however, you can use any off-the-shelf USB-C to USB-A dongle as long as it is limited to USB 2.0. USB 3.0 is not supported, and the USB 3.0 wires should not be connected to the OEM Mesh Rider radio.

 

Software setup

The Multiband OEM Mesh Rider radio uses the same IP addressing scheme as all Mesh Rider radios. Therefore, you will need to assign a static IP address to your host machine in the 10.223.0.0/16 subnet in order to access the radios. This is true for both the USB connection and the Wi-Fi connection. Details on how to configure a static IP address differ depending on your operating system, and guidelines for a Windows 10 PC are shown here.

If you are connecting to the radio over the USB port, then your system will need to have the driver for the LAN9500A chipset installed. It should be available by default in Windows machines, most Linux distributions (smsc95xx driver), and Android devices which support USB reverse tethering. Fig. 5 shows the Ethernet 2 adapter (LAN9500A USB to Ethernet) appearing after plugging in the OEM Mesh Rider radio in a Windows 10 machine.

The default configuration of the Mesh Rider radios allows them to automatically form a mesh on first boot-up without any configuration changes. You can immediately run IP-based connections over the Mesh Rider network. That said, you should at least modify the following settings for security:

1. Add a root password
2. Modify the Mesh Rider radio's SSID and Password
3. Modify the Wi-Fi radio's SSID and Password

You will be prompted to modify the root password the first time you attempt to login to the radio over the web GUI. Open a web browser and navigate to the IP address printed on the label of the device. After changing the root password, you can navigate to the Simple Configuration page.

Fig. 6 Simple Configuration page

This page allows you to modify the most common settings on the radio in one step. Aside from the changes mentioned above, you can optionally

1. Disable the DHCP client if it isn't required. This will leave only the default 10.223.0.0/16 IP address.
2. Change the default channel and bandwidth of the Mesh Rider radio.
3. Change the default channel of the Wi-Fi radio.

Make sure to make similar changes on all other radios to maintain connectivity. We encourage you to read through our guides in the Technical Library for additional tips on working with Mesh Rider radios.

Networking Information

As with all Mesh Rider radios, the default configuration behaves like a wireless ditributed layer-2 switch. Connecting devices to Mesh Rider radios is similar to connecting the same devices to an Ethernet switch. The Mesh Rider network passes traffic over the mesh transparently, and devices which need to communicate with one another need to be on the same IP subnet. Details on the Mesh Rider's networking modes are available here.

General Usage

The Multiband OEM Mesh Rider radio is designed to be integrated into an end product. Examples of common applications includes long-range industrial UAVs and UGVs, factory automation, and connected teams. The OEM Mesh Rider radio could also act as a gateway to the internet. There are also other advanced features that were not discussed in this guide. For more information, please look through the Doodle Labs Technical Library.
