Step 2 : Charging batteries, inserting battery and SIM card into the receiver, attaching quick release adapter and radio antenna

Charging the Lithium-ion battery

The rechargeable Lithium-ion battery is supplied partially charged. Before using the battery for the first time, charge it completely using the dual- battery
charger (country-specific power supply and power cord kit sold separately). The batteries come with charge battery indicator LEDs. Push the button on the
battery to check the battery charge status.
Charging takes approximately 3 hours at room temperature. If 2 batteries are charging in the dual battery charger, the batteries will be charged simultaneously.

WARNING – Ensure that nothing obstructs the vents in the back of the charger and that the charger is placed on a hard, flat and level surface, to ensure that there is airflow around the charger. Do not operate the battery charger while it is in the transport case.

LED status indicator

Beside each slot are three LED indicators (red, green, and yellow) to display the battery status:

Inserting the battery and SIM card into the receiver

Align the arrows and on the battery and battery compartment and then insert the battery as indicated in the picture. To remove the battery, slide the battery bail to the left.
 Insert the SIM card with the contacts facing upward, as indicated by the SIM card icon next to the SIM card slot. To eject the SIM card, slightly push it in to trigger the spring-loaded release mechanism.

**Tip –** The SIM card is provided by your cellular network service provider.

Note: Due to local regulations, the integrated cellular modem cannot be enabled in China, Taiwan, or Brazil. A Trimble controller integrated cellular modem or external cellular modem can be used to obtain GNSS corrections via an IP (Internet Protocol) connection.

Attaching the quick release adapter and radio antenna

Push down the spring-loaded button of the quick release adapter and then align the white dots on the bottom of the receiver and the quick release adapter. Slide in the quick release adapter and then release the button.
To install the radio antenna, screw it in clockwise. Do not overtighten!

Antenna measurement methods Tip – Optional accessories, such as the base station extension with height measurement lever, tripod, tribrach, external base battery, and remote UHF antenna are available.

Step 3: Turning on the receiver

Power button

To turn on the receiver, press the power button. All four LEDs light up, remain lit for 3 seconds, and then turn off. The power LED then immediately lights up again.
To turn off the receiver, hold the power button for 2 seconds and then release it. When holding down the power button, the battery LED remains lit, the satellite LED lights up constantly, and then turns off after 2 seconds. After releasing the power button, the battery LED stays lit for about 5 seconds and then all LEDs turn off.
 To clear the ephemeris file and reset the receiver to the factory defaults, hold down the power button for 15 seconds. The radio, Wi-Fi, and satellite LEDs turn off after 2 seconds but the battery LED remains lit. After 15 seconds, the satellite LED lights up to indicate that it is time to release the power button.

CAUTION – Resetting the receiver will permanently erase all data. Download your data before resetting your receiver.

To delete application files, hold down the power button for 30 seconds. The radio, Wi-Fi, and satellite LEDs turn off after 2 seconds but the battery LED remains lit. After 15 seconds, the satellite LED lights up and remains lit for 15 seconds, then turns off to indicate that it is time to release the power button. The battery LED remains lit for 15 seconds after you release the Power button. The receiver then restarts

Step 4: Connecting to a Trimble controller running the Trimble Access field software

The Trimble R12i receiver can communicate with any controller—for example, a Trimble TSC7 controller—that is running Trimble Access software (version 2020.10 or later) using Bluetooth® wireless technology. If you do need a cable, refer to the Trimble R12i GNSS Receiver User Guide for a list of all available cables for the receiver.

Tip – To learn more about Bluetooth connections to a Trimble R Series receiver, refer to the Trimble Access help portal at
https://help.trimblegeospatial.com/TrimbleAccess.

Step 5: Collecting GNSS data with Trimble Access field software on a Trimble controller in the field

The Trimble R12i system with Trimble Access field software is now ready to be used. Refer to the Trimble Access help portal for more information.

Aligning the system

The Trimble R12i has an integrated Inertial Measurement Unit (IMU) comprising multiple sensors that detect relative motion. Data from the IMU and GNSS signal measurements are combined by the positioning engine to compute the position (XYZ) and attitude (roll, pitch, and azimuth) of the receiver, allowing the pole tip position to be determined when the rover is tilted. You do not need to perform any specific calibration steps to align the IMU with the GNSS reference frame, and the system is unaffected by sources of magnetic interference.
To achieve a combined GNSS and inertial solution:

1. Begin a Real-Time Kinematic survey with corrections from a base station, VRS network, or Trimble CenterPoint RTX.
2.  Enter the antenna height in Trimble Access.
3.  Introduce some motion to the system, which may include tilting the pole in orthogonal directions. Trimble Access will report an “RTK+IMU” solution type along with the estimated horizontal and vertical precision once the solution has aligned. For more information, refer to the Trimble Access help portal.

Connecting to the office computer

To communicate with the office computer using a serial connection, you can either connect the receiver using a serial cable (P/N 89851-00 or P/N
59046), or by using the USB cable (P/N 89852-00 or P/N 80751) and then configuring a computer USB port as a virtual serial port.
Before you connect to the office computer, ensure that the receiver battery is fully charged.

Connecting to the receiver web interface

1. Turn on the receiver and wait for the last four digits of the receiver serial number to appear under the available Wi-Fi networks on your smartphone or office computer. For example, Trimble GNSS XXXX (where XXXX represents the last four digits of the receiver serial number).
2. Select the receiver, open a web browser and then enter the following IP address: http://192.168.142.1
   The default login values for the receiver are as follows:
   User Name: admin
   Password: password
   

Tip – Most web browsers for computers/laptops and smartphones support the receiver web interface.
