1 Before you start

1.1 Power supply

1.1.1 Battery

Reach RS2 and Reach RS2+ have a built-in LiFePO4 battery providing up to 22 hours of autonomous

work when logging data and up to 16 hours as a 3.5G or LTE rover, respectively.

1.1.2 Charging over USB

You can power and charge your Reach RS2/RS2+ over a USB-C cable using power supplies

like:

•Power bank

•USB wall adapter

1.1.3 Powering from external connector

Reach RS2/RS2+ can automatically turn on when the power is supplied to the device via

an external 9-pin bottom connector with a voltage in the range from 6 V to 40 V. You can

enable this feature in the Emlid Flow settings.

To charge the receiver 5 W is required. To operate the receiver, 7.5 W on average is required

(10 W maximum).

1.2 First setup

In this tutorial, we will walk you through the following steps:

•Installing the Emlid Flow app

•Connecting to Reach RS2/RS2+

•Performing ﬁrmware update

To do that, you will need Reach RS2/RS2+, a Wi-Fi network with an internet access, and a

smartphone or a tablet.

1.2.1 Download Emlid Flow

To manage Reach RS2/RS2+, download the Emlid Flow app on yourmobile device iOS or

Android mobile device.

Using Reach with Android devices: Some Android devices have the Battery optimization

setting enabled by default. Make sure you disabled it for Emlid Flow to avoid disconnection.

1.2.2 Power up Reach RS2/RS2+

To power up your Reach, follow the steps below:

•Hold the power button for 5 seconds to turn the unit on.

•Wait for about 30 seconds until the Power LEDs will stop blinking and the Network

LED stays solid white.

Reach RS2/RS2+ is now broadcasting Wi-Fi.

1.2.3 Connect to Reach RS2/RS2+

Using Reach with Android device: Turn oﬀ the mobile data on your device before connecting

to Reach’s hotspot.

To connect to your Reach, follow the steps below:

•Open a list of Wi-Fi networks on your smartphone or tablet.

•Connect to a network named reach:xx:xx.

•Type network password: emlidreach.

Once you successfully connected to Reach’s hotspot, you can go to Emlid Flow and set up

connection to your Wi-Fi network.

1.2.4 Set up Wi-Fi connection

Note: Make sure that your Wi-Fi network uses 2.4 GHz band.

To connect Reach to your Wi-Fi network, follow the steps below:

1. Open Emlid Flow and choose your Reach from the list.

2. Tap the Set up Reach button to open Updater for further setup process.

3. Name your Reach and apply changes.

4. Select your Wi-Fi network from the list of available networks.

5. Enter the password and tap Connect.

Reach RS2/RS2+ will stop broadcasting Wi-Fi and connect to your network. The Network

LED will blink rapidly while scanning for networks. Once Reach connects to Wi-Fi, the Network

LED will be solid blue.
