Managing Power

• • • • • •

Turning the Receiver ON/OFF

To turn on the receiver, press and hold the power button until the LEDs briefly flash. When the receiver is turned

ON, the receiver’s channels initialize and begin tracking all visible satellites at any time and location.

To turn OFF the receiver, press and hold the power button for more than three and less than 10 seconds (release the power button when the BATT LED blinks solid red). This delay prevents the receiver from being turned OFF by mistake.

The receiver will draw a small amount of power from the battery when it is turned off. If the receiver is placed in storage for a long period, such as a few months, the battery may become fully discharged. You will need to use an external power supply or recharge the battery before use.

Using Internal and External Power Sources

The receiver is powered by the internal battery or an external power source connected to the USB port. If an external power source is connected, the receiver draws power from it in preference to the battery.

Using a standard USB cable, you can connect the receiver to an external power source with 4.5 to 5.5 VDC to

operate the receiver. See “Specifications” on page 32 .

Power input greater than 6 VDC could damage the receiver.

Internal Battery

The receiver first draws power from a connected external power source. When there is no valid external power source connected or if the source has discharged lower than 4.5V, the receiver will draw its power from one highcapacity internal battery (non-removable). Depending on the use case, the hours of operation provided by the

internal battery varies. See Table 8 on page 11.

The battery is shipped from the factory with a partial charge. For maximum operating time, fully charge the battery before using the receiver.

Charging the Battery

When the battery charge is low, the BAT LED changes from solid green to yellow and then red, depending on

the remaining charge. See “Battery LED” on page 10.

When the receiver is connected to an external power source, the battery charges whether the receiver is turned

ON or OFF.

To charge the battery:

1. Connect the supplied USB 2.0 cable to the receiver’s USB port.

2. Connect the USB cable to the USB port of the power adapter.

3. Plug the power adapter into an available outlet to fully charge the battery. The time to charge the battery depends on whether the unit is ON or OFF, and if current is supplied from an external charger. The BAT

LED blinks as the battery charges.

The battery will stop charging when it is full.

Use a grounded wall outlet or grounded surge protector while charging. The socket should be located near the equipment and easily accessible.

Power Accessories

The USB 2.0 port of the GCX2 powers and charges the internal battery. The GCX2 is compatible with standard

USB power accessories used with consumer electronic devices. USB power accessories can be sourced locally as long as USB power standards are met.



Insufficient Power

If the battery becomes fully discharged and an external power supply is not connected, the receiver will shut down and automatically save recorded files. To avoid disruptions, check the BAT LED on the display panel for

the battery charge status. See “Battery LED” on page 10 for more information.

If the receiver shuts down due to insufficient power, the receiver and all communication ports become deactivated.

To restore power to your receiver and turn it back on, do one or all of the following:

•

Recharge the battery.

•

Make sure the USB cable is correctly connected to the receiver’s port.

•

Collecting Data

• • • • • •

This chapter provides general information about recording data, downloading it, and removing files to free up internal memory.

Set Recording Parameters

The Sokkia Receiver Utility (SRU) software enables you to set logging parameters, such as logging rate and types of messages, in which to record data. See the

SRU Reference Manual

or SRU Help for more information.

The GCX2 is compatible with any Sokkia field software for configuration and recording raw data.

Log Rates

The receiver provides up to 2 GB of file space on the internal (non-removable) memory card. The amount of memory used to log data depends on the logging rate. See

SRU Reference Manual

or SRU Help.

Record Data

Log raw GNSS data to the receiver’s internal memory and use the Sokkia Receiver Utility (SRU) or MAGNET

Office™ software to download the files to a computer.

Start/Stop Recording Using LED Display Panel or SRU

1. Press the power button to turn the receiver ON.

2. Wait for the STAT LED to indicate satellites are being tracked.

The STAT LED blinks green for GPS satellites and amber for GLONASS satellites. A short red blink indicates the receiver has not solved a position. Five or more satellites provide optimal positioning.

3. Press the POWER button three times within two seconds to begin recording. To begin recording data, in SRU select File ExplorerLogsStart.

4. Ensure the REC light is blinking green. This indicates that a file has opened and data collection has started.

The REC LED blinks each time data is saved to the internal memory.

5. When finished recording, press the power button three times within two seconds. Ensure the REC LED is dark. To end data recording, in SRU select File ExplorerLogsStop.

6. To turn the receiver OFF, press and hold the power button for 3 to 10 seconds until all LEDs turn dark and the BAT LED is solid red.

You can also log data using MAGNET Field software.

Collecting Data P/N: 1005278-01

24

File Management

Raw data is recorded as time-tagged measurements in a single raw data file. Each file is recorded to the receiver’s internal memory, and automatically given a name and a *.tps file extension. You can then transfer a file of collected data to a computer with file managing software, such as the Sokkia Receiver Utility (SRU). This program enables you to use an automatic naming feature, enter file names, and delete files as necessary.

See the

SRU Reference Manual

or SRU Help.

Download and Delete Files

After completing a survey, download data files to a computer or a controller for storage, post-processing, or backup. The receiver’s internal memory holds a finite amount of files, so you will want to delete files to restore memory capacity.

When the internal memory is full, the receiver stops logging data, and the REC LED turns dark/off, indicating an error condition. Existing data is not overwritten, unless AFRM mode is enabled.

There are two options for deleting raw data files from the receiver:

•

Delete all of the files using the LED display panel (i.e. hold the power button for 15 to 20 seconds).

This erases all of the files in the receivers internal memory.

•

Use a USB or Bluetooth connection to download the files to a computer. In SRU, you can select the files you want to delete from the receiver. See the

SRU Reference Manual

or SRU Help.

Once a connection is established, you can download all or some files to a computer or controller and then use the File Explorer feature in Sokkia Receiver Utility (SRU) to manage the raw data files.

For more information about using SRU to download or delete files, see the

Sokkia Receiver Utility (SRU)

Reference Manual

or SRU Help.

Troubleshooting

• • • • • •

This chapter will help you diagnose and solve some common problems that may occur with the receiver.

Do not attempt to repair equipment yourself. Doing so will void the warranty and may damage the hardware.

Check This First

Before contacting your local dealer or Sokkia Technical Support, check the following:

•

Check all external receiver connections carefully to ensure correct and secure connections. Double check for worn or defective cables.

•

Check the receiver’s internal battery for a full charge.

•

Check the power source for incorrectly connected cables, and ensure the power source is valid. See

“Specifications” on page 32 for external power requirements.

•

Check the software. Ensure the most current software version is downloaded onto the computer and the most current firmware is loaded into the receiver. For the latest updates, check the Sokkia website: http://sokkiasupport.com

•

Check Sokkia Technical Support: http://sokkiasupport.com for the latest updates.

Then, try the following:

•

Power cycle OFF/ON the receiver by pressing the Power button or by using SRU (ToolsReset receiver).

•

Restore default settings by pressing the Power button for 10 to 15 seconds or using SRU 

(ToolsFactory Reset). This restores the receiver’s parameters to the factory default settings and erases the almanac and ephemeris files. This action does not delete data files from the receiver memory.

•

Erase all files by pressing the Power button for 15 to 20 seconds or by using File ExplorerDelete All Files in SRU. This will delete all files stored in the receiver’s non-removable memory card.

If the problem persists, see the following sections for other solutions.
