Introduction
In the world of capturing Utilities, it’s common to require a connection from a GNSS receiver
to a GPR unit, working in RTK (real time kinematic), that provides accurate positional
information to the GPR unit.
This guide will explain how to connect a Trimble R1x –Series GNSS Receiver to a MALA Easy
Locator Core, via Bluetooth
•By using the Receivers Web Interface
Required Instruments
1. MALA GPR running with MALÅ Controller App for Android
2. Trimble R12i with NMEA option included. If not included, contact your sales
representative for an upgrade to your receiver.
a. This guide will also be applicable to an R10 and R12 Receivers. Just no tilt
functionality in those units is supported.
3. SIM card inside the receiver
NOTE: The NMEA output is an optional license for a Trimble GNSS. Please check with your sales
representative or technical support to see if your unit has this option, or if an upgrade is required.

Setting NMEA output using the Web Interface
The Trimble Receivers R10, R12 and R12i all have built-in a Web Interface, which can be
accessed by Wi-Fi. Henceforth in this guide all of them will be referred to as the receiver
only.
•Turn on your receiver.
•Find your receiver under the Wi-Fi list of devices and connect –no wifi password is
required.
•Open a web browser (Chrome, Firefox, Edge, Safari or similar)
•Type in the address http://192.168.142.1.
The following webpage should open:
By default, the user name and password are:
User Name: admin
Password: password

You will be prompted to change the current password to something else:
Type in the old password and select a New Password.
Make a note in a safe place for yourself on what the new password will be.
Click “Update”
NOTE: If the user forgets the password, you’ll need to reset the receiver, and will need to redo
these settings.
To reset the receiver, have the receiver turned off initially. Then Press and hold for 30 Seconds
The Radio, Wi-Fi, and Satellite LEDs turn off after 2 seconds. After 15 seconds, the Satellite LED
comes on and stays on for 15 seconds, then turns off to indicate that it is time to release the
Power button. The receiver then restarts.
From there you can re-log in to the web page, and change the password again, before changing
the NMEA settings.
