••••••
This chapter describes how to power the receiver, charge the detachable batteries, and use an external power source.
Turning On/Off the Receiver
To turn on the receiver, press and hold the power button for more than one second until the LEDs briefly flash. When the
receiver is turned on, the receiver’s channels initialize and begin tracking satellites from multiple constellations (depending
on the receiver’s supported features and current OAF).
To turn off the receiver, press and hold the power button for more than one and less than four seconds (until both the STAT
and the REC LEDs are off).
The receiver will draw a small amount of power from the batteries when it is turned off. If the receiver is
placed in storage for a long period, such as a few months, the batteries may become fully discharged. You will
need to use an external power supply or recharge the batteries before use.
Powering the Receiver
The receiver is powered by the detachable, rechargeable batteries or an external power source connected to the power
port. If an external power source is connected, the receiver draws power from it over the battery.
Managing Power

Managing Power
Detachable External Batteries
Each detachable battery provides between 5 and 10 hours of operation, depending on the receiver mode.
To check the status of the detachable batteries, view the BATT LED or check the status using available Topcon software.
Charging the Batteries
The batteries are shipped from the factory without power. Fully charge the batteries before surveying. You can use the
power supply unit or the battery charging cradle to charge the batteries.
Power Supply Unit
The power supply unit (p/n 22‐034101‐01) charges the external batteries when connected to a grounded outlet. This unit
converts the alternating current (AC) normally supplied from an electrical outlet to a direct current (DC) used to charge
the batteries and/or power the receiver.
The power supply unit is designed for indoor use only. Do not use in a damp or a wet environment.
Do not expose the power supply to rain or snow. It should only be used for charging the batteries.
Do not use as a power source during surveying.
You can connect the power supply unit to the charging cradle or directly to the receiver. See “Power Supply Unit” on
page 32. The power supply has the following specifications:
• input voltage – between 100 and 240 V AC
• frequency of input power – between 50 Hz and 60 Hz
• output voltage – 12 V DC@2.5 A (30 W)

Managing Power
Changing the Batteries while Surveying
It is safe to change a depleted battery with a fully charged one while surveying (i.e., on the fly) without turning off the
receiver. Before doing this, make sure the other battery has enough charge to power the receiver while changing the
depleted battery. The surveying will not be disrupted. If needed, repeat this procedure for the second battery.
Using an Auxiliary Power Source
In addition to the detachable batteries, you can connect the receiver to an external power source, such as a vehicle battery
with 9 to 21 VDC, to operate the receiver and for continuous use of the receiver if the detachable batteries become
discharged.
Power input greater than 21 VDC could damage the receiver.
To connect the receiver to an auxiliary battery (Figure 16 on page 4‐40):
Use the ODU‐to‐alligator clips cable (p/n 14‐008097‐01LF) to directly connect the auxiliary battery and the receiver’s
power port (without SAE).
When powering the receiver using external batteries, set the charger mode to Off; otherwise, the
detachable batteries will also charge, causing operation time to decrease.

The receiver’s Non‐Volatile Random Access Memory (NVRAM) holds data required for satellite tracking, such as ephemeris data
and receiver position. The NVRAM also keeps the current receiver’s settings, such as active antenna input, elevation masks and
recording interval, and information about the receiver’s internal file system. A factory reset clears the receiver’s NVRAM and
restores the receiver’s factory default settings.
Although a factory reset or clearing the NVRAM is not recommended as a common practice, there are times when it can
eliminate communication or tracking problems.
After a factory reset, the receiver requires time to collect new ephemerides and almanacs (around 15 minutes).
A factory reset will not delete any files already recorded in the receiver’s memory, and the NVRAM keeps information about the
receiver file system.
There are two ways you can perform a factory reset: using TRU and using the LED display panel.

SD/SDHC Card
The SDHC card slot is located to the left of the LED Display Panel
inside the battery compartment and connects an optional
SD/SDHC card to the receiver board to provide memory. Once
installed, the SD/SDHC card usually remains inside the receiver.
You can access the data that resides on the SD/SDHC card via the
USB or serial port, or Bluetooth wireless technology (see
“Managing Files” on page 64). A secure digital card can be
purchased at a local computer supply store.
Installing the SD/SDHC Card

3.
Make sure the receiver is turned off.
Remove the detachable battery to the left of the LED
Display panel.
Carefully insert the SD/SDHC card, label‐side down, into the
card slot located at the top of the battery compartment.
Once the receiver is turned on, the receiver board will
detect the SD/SDHC card, and it will be ready to use as needed.

Always initialize the file system on the installed SD/SDHC card before the first use. The Initialization procedure
is described below.
Memory
P/N: 7010‐1004

The GR‐5 supports a removable SDHC memory card to log raw data files. The memory card must be initialized before its
first use. Initializing the memory card while in the receiver ensures the card is formatted to the TPS proprietary file system
(TPFS). This file system allows the receiver to create, store, retrieve, delete, and restore raw data files.
It is also advisable to re‐initialize the memory card periodically (e.g., quarterly). This erases any data on the card, checks
for bad blocks, and sets the card up afresh.
The user can use TRU to initialize the file system.

Initializing the File System
The Topcon Receiver Utility (TRU) software enables you to set logging parameters, such as logging rate and types of messages,
in which to record data. This software is supplied on the GR‐5 CD. See the TRU Online Help for more information. The GR‐5 is
compatible with any Topcon field software for configuration and recording raw data.
Logging Rates
The amount of memory used to log data depends on the logging rate. For more information about setting logging rate
parameters, see the TRU Online Help.
Recording Data
You can log raw GNSS data to the receiver’s SD/SDHC card and use the Topcon Receiver Utility (TRU) or MAGNET Office™
software to download the files to a computer.
To start or stop recording data, use the LED display panel or TRU:

Raw data is recorded as time‐tagged measurements in a single raw data file. Each file is recorded to the receiver’s memory, and
automatically given a name and a *.tps file extension. You can then transfer a file of collected data can to a computer with file
managing software, such as the Topcon Receiver Utility (TRU), which is supplied on the GPS+ CD. These programs allow you to
use an automatic naming feature, enter file names, and delete files as necessary. For more information, see the TRU Online Help
embedded in the software.
Downloading and Deleting Files
After completing a survey, download data files to a computer or a controller for storage, post‐processing, or backup. The
SD/SDHC cards hold a finite amount of files, so you will want to delete files to increase memory capacity.
When the memory is full, the receiver stops logging data, and the REC LED turns dark/off, indicating an error condition. Existing
data is not overwritten.
To delete raw data files from the receiver, use a USB, serial, or Bluetooth connection to download the files to a computer. In
TRU, you can select the files you want to delete from the receiver. See the TRU Online Help for more information.
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 Topcon Receiver Utility (TRU) to manage the raw data files. For more information about using TRU to download or
delete files, see the Topcon Receiver Utility (TRU) Online Help embedded in the software.
