RTK Smart Battery Console

The RTK Smart Battery has a built-in 6600mAh/14.8V lithium battery. The pole is integrated with a battery level/status display panel (see right figure), a power button, and a Type-C charge port. The functions of the button/indicator lights are defined as follows:

Battery ON/OFF

ON: The battery will be powered on after 2 long presses. When the battery is OFF, press and hold the power button for at least 1 second, and release the button after all battery level indicator lights flash at the same time, then press and hold the button for at least 1 second again until the status indicator is on. This indicates that the battery has been powered on successfully.
OFF: The battery will be powered off after 2 long presses. When the battery is ON, press and hold the power button for at least 1 second, and release the button after all battery level indicator lights flash at the same time, then press and hold the button for at least 1 second again until the status indicator is off. This indicates that the battery has been powered off successfully

Checking Battery Level (Green)

When the battery is ON, see the battery level indicators for the battery level. When the battery is OFF, press the power button once to display the battery level. Battery levels are defined as follows:

Checking Battery Status (Red Power Indicator)
Once the battery is ON, its status will be displayed on the console. Battery statuses are defined as follows:

Charging Battery

The battery can be charged when it is either ON* or OFF. During the battery charging, the battery level indicators corresponding to the current battery level will be on, while the rest lights will flash in series, indicating that the battery is being charged. After charging is completed, all battery level indicators will be on.

Warning

The battery must be charged with the charging devices designated by XAG. The user shall bear the responsibility for all the consequences caused by the use of the charging devices not designated by XAG. Charging while the RTK is turned on may result in slow charging or power loss. It is recommended to charge when the RTK is powered off.

Charge via the Type-C port

Console of the RTK Positioning Module

The Console of RTK Positioning Module for Agricultural Use is composed of three function buttons and three corresponding indicator lights in different colors (see right figure). The functions of the button/indicator lights are defined as follows:

Checking Operation Status

Checking Network Status

Checking Positioning Status

Checking/Setting Working Mode

Press and hold F1 to enter Wi-Fi AP Hotspot mode with flashing light. A shared network named “XBASE + Serial Number” will be found with a default password 20070401. Press and hold F3 to enter Add Device mode with simultaneous flashing red, yellow and blue. With a device being added or if a device fails to be added within one minute, you will exit Add Device mode.

Buzzer Alert

When the difference between the coordinates manually entered and the actual coordinates is more than 8 meters, the buzzer sends an alert. When the voltage is lower than 12.5V, the buzzer sends an alert. The alert will be stopped when the voltage rises to 13.5V or above.

Activating BOOT Mode

1. When the module is OFF, press and hold F3 to power on*.
2. If the buzzer beeps for three times, then the red light flashes slowly for 30 seconds (WLAN initialization) before flashing quickly, and the remaining indicators are off (see figure on right), it means BOOT mode is activated. Otherwise, BOOT mode is not activated

Activating WLAN Pairing Mode

Turn on the module, when the red right (corresponding to F1) is on, press and hold F2 for at least 3 seconds and release after hearing a beep. If the red and blue lights are off and yellow light flashes twice, it means the Mushroom Head has started pairing. Upon successful pairing, the module will automatically exit the pairing mode and start normal operation

Reset

Press F2 and F3 at the same time when powered on and release after hearing a beep. After around 8 seconds, the Mushroom Head automatically restarts and the factory default settings are restored.

Setting up Portable Base

Location Selection
Select solid and flat ground with open space above. There should be no obstacles over the elevation angle of 15° for continuous tracking and observation of the satellite and high quality satellite signals.
Mounting
Erect the Tripod and align as per the operation standard for the RTK base. Connect the Mushroom Head to the Tripod’s connecting rod, turn on the power, and secure the connecting rod.

1. Fix Tripod: Mount the Tripod to the Triangle Stand and secure. Note: When there is no datum mark, make sure the Tripod is in firm contact with the ground. The height of the Tripod can be
2. changed as needed, preferably 1.5m or higher.
3. Erect the Tripod and keep the level bubble centered.
4. Connect the extension rod corresponding to the Mushroom Head and turn on the power.
5. Fix the Mushroom Head on the Tripod to complete the setup of the hardware equipment of the Portable Base.

System Settings
After the base is paired, click “Base Settings”, set the RTK device as a portable base, and select the way to obtain coordinates. Ways to obtain coordinates include low-precision capturing, high-precision capturing, and manual input.
Low-precision Capturing
Click Low-precision Capturing, and the device starts capturing coordinates automatically. After the signal becomes stable, the Mushroom Head will be automatically set as a portable base. There may be a margin of error between the coordinates captured with low precision and the actual coordinates.
High-precision Capturing
High-precision Capturing performs differential positioning with the RTCM signals from a fixed base that has been set up to obtain accurate coordinates. How to operate: Click High-precision Capturing (base assistance), and the base searches for fixed bases within 70 km via network signals. Select a desirable fixed base as your supporting base and click OK. When the parameter “Positioning” on home page displays FIX, the base is set up.
Manual Input
This mode is suitable for the setup of a second base. To set up a second base at the fixed point that has been surveyed before, input the coordinates captured during the first setup into the device, and the device will automatically generate and broadcast RTCM data. How to operate: Click Manual Input and enter the exact coordinates into the pop-up window; Click OK and when the parameter “Positioning” on home page displays FIX, the base is set up.
