Regulations and Safety

The Bluetooth module inside your receiver is a radio-modem transmitter and receiver. Regulations regarding the use of the radio-modems vary greatly from country to country. In some countries, the unit can be used without obtaining an end-user license. Other countries require end-user licensing. Consult your local communications governing agency for licensing information. Before operating this receiver, determine if authorization or a license to operate the unit is required in your country. It is the responsibility of the end user to obtain an operator’s permit or license for this receiver radio-modem for the location or country of use.

STATEMENT ACCORDING FCC PART 15.19

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

STATEMENT ACCORDING FCC PART 15.21

Modifications not expressly approved by Trimble could void the user's authority to operate the equipment.

STATEMENT ACCORDING FCC PART 15.105

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: – Reorient or relocate the receiving antenna. – Increase the separation between the equipment and receiver. – Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help.

Type Approval

Type approval, or acceptance, covers technical parameters of the equipment related to emissions that can cause

interference. Type approval is granted to the manufacturer of the transmission equipment, independent from the operation or licensing of the units. Some countries have unique technical requirements for operation in particular radiomodem frequency bands. To comply with those requirements, Trimble may have modified your equipment to be granted Type approval. Unauthorized modification of the units voids the Type approval, the warranty, and the operational license of the equipment.

Safety

EXPOSURE TO RADIO FREQUENCY RADIATION

You must maintain a minimum separation distance of 20 cm (approximately 8 in.) between yourself and the radiating GSM antenna for this device to satisfy the RF Exposure requirements of the FCC. For mobile operation, the maximum gain of the GSM antenna must not exceed 0 dBi.

Overview 2

Trimble R7 GPS Receiver Operation

WARNING – Operating or storing the receiver outside the specified

temperature range can damage it. For more information, see Physical specifications, page 76.

High-power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. This does not harm the instrument, but it can prevent the receiver electronics from functioning correctly. Avoid using the receiver within 400 meters of powerful radar, television, or other transmitters. Low-power transmitters such as those used in cellphones and two-way radios normally do not interfere with receiver operations.

For more information, contact your local Trimble distributor.

To power supply

Figure 3.12 Connecting an external radio

5. Connect an external power source to Port 2 on the receiver.

External rover radios must have their own power source because the internal Lithium-ion batteries do not supply enough voltage. Alternatively, supply external power to port 2 of the receiver, and enable power out on port 3. Base radios must have their own power source because of their high power consumption.

Alternatively, you can apply external power directly to the radio, if it supports it.

You can use a 10 Ah battery, a 6 Ah battery, or camcorder batteries. The choice of power supply depends on the application, and whether you are using the radio as a reference

32 Trimble R7/R8 GPS Receiver User Guide

or rover radio. For more information about the power capabilities of the Trimble R7 receiver, see Batteries and Power, page 44.

6. Configure the external radio using Trimble Survey Controller software. Alternatively, you can configure a TRIMMARK 3 radio using the WinFlash software or the configuration software supplied with the radio.

For more information, refer to the Trimble Survey Controller User Guide or the appropriate Help.

7. Set up any other equipment as required, depending on whether you are using the radio as a reference or a rover radio.

30.1 Cellular modems

Setting up the Receiver 3

You can use a cellular modem instead of a radio as your data communications link. Cellular modems and other radio links can be used to extend the limits of your surveys.

To connect a cellular modem to a Trimble R7 receiver, you need the following:

• A Trimble R7 receiver

• A custom-designed cellular modem, or a cellphone that can

transmit and receive data

• Serial (cellphone to DB9) cable (supplied with the cellular

modem or phone)

• Trimble DB9 to 0-shell Lemo cable

This cable is suitable only if flow control can be disabled on the cellular modem. If the cellular modem does not support this functionality, a special cable is required. For more information, refer to the document Using Cellular and CDPD Modems for RTK, which is available from your local Trimble Distributor.

30.3 CompactFlash cards

The Trimble R7 receiver logs data internally on a CompactFlash card. However, it only support the Type I CompactFlash card. Trimble recommends that you use an industrial-rated CompactFlash card, as commercial cards have a limited operating temperature range.

Before logging data to a CompactFlash card, format the card to ensure the integrity of the file system. To format the card, insert it in the receiver and then hold down the power button for 30 seconds.

Note – Make sure that you format your CompactFlash card in the receiver. This prevents data on the card from being corrupted if the card is removed while data is being logged. Formatting the card in your computer may cause data corruption, or loss of data.

When inserting the card, make sure that it slides into the card slot properly.

Trimble R7 GPS Receiver Operation

36 Trimble R7/R8 GPS Receiver User Guide

WARNING –

– The Trimble R7 receiver allows for a maximum of 512 files on the CompactFlash card, regardless of the card’s capacity. The file names must be in 8.3 format, otherwise files copied to the CompactFlash card may cause data corruption or loss of data when logging. – If the card does not seat into the pins correctly, do not use force or you may damage the pins. Remove the card and carefully reinsert it.

4.4 Logging Data

You can log data to the CompactFlash card in the receiver, or to the survey device.

Trimble R7/R8 GPS Receiver User Guide 41

4 General Operation

44.1 Logging internally

The Trimble R7 receiver logs GPS data internally on a CompactFlash card. You can then use the Trimble Data Transfer utility to transfer logged data files to your office computer. The transferred files are in Trimble DAT (.dat) format.

WARNING – The Trimble R7 receiver allows for a maximum of 512 files on

the CompactFlash card, regardless of the card’s capacity. The file names must be in 8.3 format, otherwise files copied to the CompactFlash card may cause data corruption or loss of data when logging.

Data is logged using the current logging settings configured in the receiver. Data files logged internally are named automatically.

To begin internal logging, press [D]. The Logging/Memory LED lights up.

Trimble R7 GPS Receiver Operation

To stop logging, hold down [D] for at least two seconds. The Logging/Memory LED turns off.

Note – When the CompactFlash card is full, the receiver stops logging data, and the Logging/Memory LED switches off. Existing data files are not overwritten.

Approximate storage requirements for different logging rates are shown in Table 4.2. The values shown are for a one-hour logging session with six satellites visible.

Table 4.2 Storage requirements

Logging rate Memory required

10 Hz 2,588 KB

1Hz 335 KB

5 seconds 87 KB

15 seconds 37 KB

42 Trimble R7/R8 GPS Receiver User Guide

Note – If power is lost, or the CompactFlash card is removed while logging, the file system is designed so that a maximum of ten seconds of data will be lost, regardless of the logging rate. To ensure that this behavior occurs, use GPS Configurator to perform a quick format of the CompactFlash card before logging data to the card for the first time.

44.2 Logging to a Trimble controller

When the Trimble R7 receiver is connected to a Trimble controller, you can log GPS data from the receiver to the controller, or to a PC card inserted in the controller. When you use a Trimble controller, you do not use the receiver’s controls. Instead, you use the controller functions to set logging options, specify filenames, and to control when logging occurs.

Data is stored in job files, which can be transferred to your office computer using Trimble’s Data Transfer utility.

For more information on logging data from a receiver using a Trimble controller refer, to the user guide for your particular controller.

4.5 Resetting to Defaults

WARNING – Do not hold down [P] for more than 30 seconds. After 30

seconds, any application files stored in the receiver are deleted and the CompactFlash card is reformatted.

To reset the receiver to its factory default settings, hold down [P] for at least 15 seconds.

Resetting the receiver to its factory defaults also deletes any ephemeris file in the receiver.

For more information, see Chapter 9, Default Settings.

Trimble R7/R8 GPS Receiver User Guide 43

4 General Operation

4.6 Formatting a CompactFlash Card

WARNING – Formatting a CompactFlash card while it is in the receiver

deletes all the data files on the card and all the application files in the receiver.

To format a CompactFlash card for use in a Trimble R7 receiver, insert the card in the CompactFlash port and then hold down [P] for at least 30 seconds. After 15 seconds, the receiver is reset to its factory defaults, and any ephemeris file is deleted. After 30 seconds, any files stored on the card are deleted and the CompactFlash card is reformatted.

Note – When you use [P] to format the CompactFlash card, a quick format is performed. A quick format reformats the card for use with the Trimble R7 receiver receiver and deletes all data on the card. A full format checks the card for errors or bad sectors, and is only necessary if the card is corrupted. To perform a full format, use the GPS Configurator software.

Trimble R7 GPS Receiver Operation

4.7 Batteries and Power

For more information, see The GPS Configurator Software, page 68.

WARNING – Do not damage the rechargeable Lithium-ion battery. A

The Trimble R7 receiver can be powered either by its two internal batteries or by an external power source connected to Port 2 or Port 3. The charge provided by the internal batteries depends on the type of

44 Trimble R7/R8 GPS Receiver User Guide

General Operation 4

survey and operating conditions. Typically, one battery provides about

3.5 hours of power during an RTK survey using the internal radio, and about 5 hours during a survey without the internal radio.

The external power source is always used in preference to the internal batteries. When there is no external power source connected, or if the external power supply fails, the internal batteries are used. The internal batteries are drained in turn, and the receiver automatically switches to the full battery when the first battery is drained.

If no external power is supplied and both internal batteries are drained, none of the data that you have logged is lost. When internal or external power is restored, the receiver restarts in the same state as when power was lost. For example, if the receiver was logging data, the data file is not corrupted, and when power is restored the receiver resumes logging with the same settings as before.

The power supply that comes with the Trimble R7 receiver charges the internal batteries while they are still in the receiver. To do this, connect the power supply to the power/serial data cable, connect the cable to Port 2 on the receiver and then connect the power supply to an AC power source, as shown in Figure 4.2 on page 46.

Figure 4.2 Charging the batteries

To A C power supply

The two internal batteries take approximately eight hours to charge. They are charged individually, so each battery takes approximately four hours to charge. The internal batteries start charging whenever an external power supply of greater than 15 V is detected.

46 Trimble R7/R8 GPS Receiver User Guide

WARNING – Avoid contact with the rechargeable Lithium-ion battery if it

Each receiver in your system is supplied with two internal Lithium-ion battery packs. To charge both sets of batteries, connect both receivers to power supplies as shown in Figure 3.2.

47.1 Battery charging and storage

All battery types discharge over time when they are not being used. Batteries also discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long periods of time, make sure it is fully charged before storing and re-charged at least every three months.

General Operation 4

WARNING – Charge and use the rechargeable Lithium-ion battery only in

strict accordance with the instructions. Charging or using the battery in unauthorized equipment can cause an explosion or fire, and can result in personal injury and/or equipment damage. To prevent injury or damage: – Do not charge or use the battery if it appears to be damaged or leaking. – Charge the Lithium-ion battery only in a Trimble product that is specified to charge it. Be sure to follow all instructions that are provided with the battery charger. – Discontinue charging a battery that gives off extreme heat or a burning odor. – Use the battery only in Trimble equipment that is specified to use it. – Use the battery only for its intended use and according to the instructions in the product documentation.

Charging the Lithium-ion battery

The rechargeable Lithium-ion battery is supplied partially charged. Charge the battery completely before using it for the first time. If the battery has been stored for longer than six months, charge it before use.

To protect the battery from deep discharge (5 volts or less), the Trimble R7 receiver is designed to switch batteries or cease drawing power when the battery pack discharges to 5.9 volts.

Trimble R7 GPS Receiver Operation

Trimble R7/R8 GPS Receiver User Guide 47

4 General Operation

A battery that has reached the deep discharge level cannot be recharged and must be replaced. The following recommendations provide optimal performance and extend the life of your batteries:

• Fully charge all new batteries before use.

• Do not allow the batteries to discharge below 5 volts.

• Keep all batteries on continuous charge when not in use.

Batteries may be kept on charge indefinitely without damage to the receiver or batteries.

• Do not store batteries in the receiver or external charger unless

power is applied.

• If you must store the batteries, fully charge them before storing

and then recharge them at least every three months.

Disposing of the rechargeable Lithium-ion battery

Trimble R7 GPS Receiver Operation

Discharge the Lithium-ion battery before disposing of it. When disposing of the battery, be sure to do so in an environmentally sensitive manner. Adhere to any local and national regulations concerning battery disposal or recycling.

47.2 Operating with the TSCe controller

If the receiver is being powered by its internal batteries, it does not supply power to the TSCe controller when they are connected. However, the TSCe controller batteries and the Trimble R7 receiver batteries can be charged at the same time from the same power supply. To charge both sets of batteries, use two standard power/serial data cables to connect the TSCe controller and the receiver to a power supply, as shown in Figure 4.3.

Figure 4.3 Charging receiver and TSCe batteries

47.3 Power output

If the receiver is being supplied with power from an external source, power is automatically output on Port 1. The output voltage is approximately 0.5 V less than the input voltage. Port 1 outputs a maximum voltage of 20 V, even if the input voltage is higher.

You can use GPS Configurator or Trimble Survey Controller software to enable power output on Port 3. Port 3 can be enabled for power output regardless of whether power is supplied internally or externally.

Trimble R7/R8 GPS Receiver User Guide 49

4 General Operation

On Port 3, the output voltage is approximately 0.5 V less than the input voltage. For example, if power is being supplied from the internal Lithium-ion batteries, the maximum battery voltage is 8.4 V, so the maximum output voltage is 7.9 V.

Note – When you start a survey using the Trimble Survey Controller software, and you are using an external radio, the software automatically enables power output on Port 3.

47.4 Firmware

A receiver’s firmware is the program inside the receiver that makes the receiver run and controls the hardware. When you need to upgrade the firmware for your Trimble R7 receiver, Trimble recommends that you use the WinFlash software. For more information, see The WinFlash Software, page 69.

Trimble R7 GPS Receiver Operation

50 Trimble R7/R8 GPS Receiver User Guide

WARNING – Upgrading the firmware deletes all application files on the

Trimble R7 receiver.

An alternative method of upgrading your firmware is to copy the .elf file directly to the CompactFlash card from your computer:

1. Connect the CompactFlash card to your desktop computer.

2. Using Windows Explorer, copy the .elf file from your computer to the CompactFlash card.

3. Disconnect the CompactFlash card from your computer and insert it into the receiver.

4. Turn the receiver off.

5. Hold down [D] and press [P].

The receiver starts up in Monitor mode, automatically detects the newer version of the firmware, and installs it. In Monitor mode, the red SV Tracking LED is lit solidly and the yellow Logging/Memory LED flashes slowly.

The upgrade takes about two minutes. Once the upgrade procedure is complete, the receiver restarts automatically.

Trimble R7/R8 GPS Receiver User Guide 51

5 Configuration

The Trimble R7 receiver has no controls for changing settings. To configure the receiver, use external software, such as GPS Configurator or Trimble Survey Controller.

To configure the Trimble R7 receiver, do one of the following:

• Configure the receiver in real time

• Apply the settings in an application file

This chapter provides a brief overview of each of these methods, and describes the contents and use of application files.

5.1 Configuring the Receiver in Real Time

The GPS Configurator and Trimble Survey Controller software support real-time configuration of the Trimble R7 receiver.

Trimble R7 GPS Receiver Operation

When you configure the receiver in real time, you use one of these software applications to specify which settings you want to change. When you apply the changes, the receiver settings change immediately.

Any changes that you apply to the receiver are reflected in the Current application file, which is always present in the receiver. The Current application file always records the most recent configuration, so if you apply further changes (either in real time or using an application file) the Current file is updated and there is no record of the changes that you applied originally.

For more information on configuring the receiver in real time, see Chapter 7, Software Utilities.

52 Trimble R7/R8 GPS Receiver User Guide

Configuration 5

5.2 Configuring the Receiver Using Application

Files

An application file contains information for configuring a receiver. To configure a receiver using an application file, you need to create the application file, transfer it to the receiver, and then apply the file settings. The GPS Configurator software does this for you automatically when you work with configuration files.

For more information on applying application files, see Chapter 7, Software Utilities.

5.3 Application Files

An application file is organized into records. Each record stores configuration information for a particular area of receiver operation. Application files can include the following records:

• File Storage

• General Controls

Trimble R7 GPS Receiver Operation

• Serial Port Baud/Format

• Reference Position

• Logging Rate

• SV Enable/Disable

• Output Message

• Antenna

• Device Control

• Static/Kinematic

• Input Message

• Timed Activation

Trimble R7/R8 GPS Receiver User Guide 53

5 Configuration

An application file does not have to contain all of these records. When you apply an application file, any option that is not included in the records in the file remains at its current setting. For example, if you apply an application file that only specifies the elevation mask to use, all other settings remain as they were before the application file was applied.

You can store up to twenty different application files in battery-backed memory on the receiver. You can apply an application file’s settings at the time it is transferred to the receiver, or at any time afterwards.

53.1 Special application files

The Trimble R7 receiver has three special application files, which control important aspects of the receiver’s configuration.

Trimble R7 GPS Receiver Operation

Default application file

The default application file (Default.cfg) contains the original receiver configuration, and cannot be changed. This file configures the receiver after it is reset. To reset the receiver, hold down [P] for at least 15 seconds, or use the reset option in the GPS Configurator software.

For more information, see Default Settings, page 80.

Although you cannot change or delete the default application file, you can use a power up application file to override any or all of the default settings.

Current application file

The current application file (Current.cfg) reflects the current receiver configuration. Whenever you change the receiver’s configuration, either in real time or by applying an application file, the current file changes to match the new configuration.

You cannot delete the current file or change it directly, but every change to the receiver’s current configuration is applied to the current file as well.

54 Trimble R7/R8 GPS Receiver User Guide

Configuration 5

When you turn off the receiver then turn it on again, all the settings from the current application file are applied, so you do not lose any changes that you have made. The only exceptions are the following logging parameters:

• Logging rate

• Position rate

• Elevation mask

These parameters are always reset to the factory default values whenever the receiver is switched off.

Power Up application file

the power up application file (power_up.cfg) is optional. if a power up file is present, its settings are applied whenever the receiver is turned on.

In this file, you can specify that the receiver is reset to defaults before the power up settings are applied. This ensures that restarting the receiver always results in the same configuration. This method is useful for defining “default” settings for the receiver that differ from those in the default file, which cannot be changed.

Trimble R7 GPS Receiver Operation

Alternatively, you can specify that the power up settings are applied immediately after the current application file’s settings have been applied. Restarting the receiver results in a configuration that uses your default settings for the options you define in the power up file, but the current settings for all other options.

By default, there is no power_up application file on the receiver. To use a power up application file, you must create and save a power_up application file in the GPS Configurator software. If you save this file to disk, the file is called power_up.cfg. the extension .cfg is used by convention to identify application files on the office computer. when you transfer this file to the receiver, the file is saved on the receiver as power_up, and becomes the new power up file.

Trimble R7/R8 GPS Receiver User Guide 55

Trimble R7 GPS Receiver Operation

5 Configuration

The power up file is the only special application file that you can overwrite or delete from the receiver.

53.2 Timed application files

A timed application file contains a Timed Activation record which specifies when this file is to be applied. The main use of a timed application file is to automatically start or stop logging at a predefined time.

The Timed Activation record specifies:

• the UTC date and time when the application file is to be applied

for the first time

• the interval at which the file is to be reapplied

If you do not specify a repeat interval, the settings are applied only once, at the specified time. If the file specifies a repeat interval, the file’s settings are reapplied at the specified interval until the file is deactivated.

Note – If the receiver is logging continuously, the current logging takes precedence over any timed application file stored in the receiver.

Defining timed application files

To send timed application files to a Trimble R7 receiver, set up scheduled survey sessions in the GPS Configurator software. You can define multiple sessions, each specifying:

• basic logging parameters (data logging rate, position logging

rate, and elevation mask)

• a starting time

• a duration

56 Trimble R7/R8 GPS Receiver User Guide

Configuration 5

When you apply the current settings in the GPS Configurator software, each defined survey session is sent to the Trimble R7 receiver as a pair of timed application files: the first includes the logging settings and start time, and the second contains settings that stop logging at the end time (which is calculated automatically from the duration you specify).

For more information on scheduled survey sessions, refer to the GPS Configurator Help.

The receiver can store up to 20 application files, so you can define a maximum of 10 scheduled survey sessions (10 pairs of start/stop timed application files).

Sleep mode

Whenever you press [P] to turn off the Trimble R7 receiver, the receiver checks for a timed application file that is due to be activated in the future. If one exists, the receiver goes into Sleep mode instead of turning off.

In Sleep mode, the yellow Logging/Memory LED flashes every three seconds. The receiver wakes up five minutes before the scheduled activation time, so that it is ready to begin logging at the scheduled time.

Trimble R7 GPS Receiver Operation

53.3 Applying application files

An application file’s settings do not affect the receiver’s configuration until you apply the application file. You can do this at the same time that you save the file. Alternatively, save the file on the computer or in the receiver, then open it later and apply its settings.

Note – If the application file is a timed file, its settings do not take effect as soon as you apply the file, but at the time that the file specifies for its activation.

Trimble R7/R8 GPS Receiver User Guide 57

Trimble R7 GPS Receiver Operation

5 Configuration

53.4 Storing application files

You can store application files that you create in the GPS Configurator software on the receiver and on the computer. For example, each file can represent a different user sharing the same receiver, or a particular mode of operation or survey style. Saving application files on your computer as well as in your receiver is optional, but it is useful because:

• it gives you a permanent copy of the settings you have sent to a

receiver, for audit or your own reference.

• you can use the same file to configure multiple receivers

identically.

• you can use an existing application file as a template for creating

other application files with similar settings.

53.5 Naming application files

The application filename in the office computer and in the receiver is always the same. This makes it easier to recognize and keep track of your application files.

When you change the name of the application file in the receiver, this changes the application filename on your computer. When you transfer an application file from the receiver and save it to the computer, the system renames the file to match the internal receiver file. However, if you use Windows Explorer, for example, to change the .cfg filename on the computer, this does not change the internal receiver filename. This means that the GPS receiver does not recognize the change to the filename on the computer.

Note – When the receiver is connected to a USB port on a computer, it is treated as a peripheral device of the computer. If the receiver is unplugged or turned off, a warning message appears on the computer.

6.2 Transferring Data

Transfer the data files to the computer using the Trimble Data Transfer utility. You can run this utility as a standalone program or from within the Trimble Geomatics Office software. For more information, refer to the Data Transfer Help.

62 Trimble R7/R8 GPS Receiver User Guide

Note – When you connect to a receiver in the Data Transfer utility, you must use a GPS Receiver (R/5000 Series) device definition. If you use a GPS Receiver (4000 Series) device definition, the Data Transfer utility will be unable to establish communication with the receiver.

When transfer is complete, the Data Transfer utility automatically converts the file to the DAT format. If you are using Data Transfer from within the Trimble Geomatics Office software, the Check-in dialog appears. For more information, refer to the Trimble Geomatics Office

User Guide.

Note – A file in DAT format is approximately six times the size of the corresponding file in the Trimble R7 receiver internal format. Before transferring files, make sure that there is enough space on your computer.

6.3 Transferring Files Directly from a

CompactFlash Card

In a Trimble R7 receiver, all data is stored on an internal CompactFlash card. There are two ways to transfer files between the receiver and the office computer:

Transferring Data 6

Trimble R7 GPS Receiver Operation

• Connect the receiver to the office computer and use the Data Transfer utility to transfer files.

• Remove the CompactFlash card from the receiver and connect it directly to your office computer, where it functions like a normal disk drive. Use Windows Explorer to transfer files.

When you use the Data Transfer utility to transfer data files from the CompactFlash card while it is still inserted in the receiver, the Data Transfer utility converts the raw receiver data (.T01) files you select into the Trimble DAT file format.

However, if you connect the CompactFlash card to your computer and then copy or move files to your computer, it treats the card like any other disk drive, and transfers the files without converting them. You need to convert these raw receiver files to DAT format files before you can use them on your office computer.

Trimble R7/R8 GPS Receiver User Guide 63

Trimble R7 GPS Receiver Operation

6 Transferring Data

You can convert receiver data files by using a Windows Explorer extension which is installed on your computer when you install the Data Transfer utility.

Note – Although this extension is only available if you have the Data Transfer utility installed, you do not have to run the Data Transfer utility to use it.

To convert a .T01 file on your office computer into the DAT format:

1. On your office computer, open Windows Explorer and navigate to the location of the .T01 file.

2. Right-click the file, and from the menu that appears select Convert to DAT format:

The DAT File Conversion dialog appears while the file is converted. When the dialog disappears, the file conversion is complete.

A new file with the same filename but a .dat extension appears in the same folder as the .T01 file.

64 Trimble R7/R8 GPS Receiver User Guide

6.1 Deleting Files in the Receiver

You can delete files stored in the receiver at any time. Do one of the following:

• Use the Data Transfer utility in the Trimble Geomatics Office software.

• Use the TSCe controller.

• Turn on the receiver and then hold down [P] for 30 seconds. When you use this method, all data is deleted, and the CompactFlash card is reformatted.

9 Default Settings

All Trimble R7 receiver settings are stored in application files. The default application file, default.cfg, is stored permanently in the receiver, and contains the factory default settings for the Trimble R7 receiver. Whenever the receiver is reset to its factory defaults, the current settings (stored in the current application file, current.cfg) are reset to the values in the default application file.

You cannot modify the default application file. however, if there is a power up application file (power_up.cfg) in the receiver, the settings in this file can be applied immediately after the default application file, overriding the factory defaults.

For more information, see Application Files, page 53.

9.2 Resetting to Factory Defaults

To reset the receiver to its factory defaults, do one of the following:

• On the receiver, press and hold down [P] for 15 seconds.

• In the GPS Configurator software, select Connect to Receiver and

then click

9.3 Examples

Reset receiver in the General tab.

The following examples show how the Trimble R7 receiver uses the default settings and special application files in various situations.

93.1 Default behavior

The factory defaults are applied whenever you start the receiver. If a Power Up file is present in the receiver, its settings are applied immediately after the default settings, so you can use a Power Up file to define your own set of defaults.

93.2 Power up settings

When you turn the receiver off, any changes that you have made to logging settings are lost and these settings are returned to the factory defaults. Other settings remain as defined in the Current file. The next time you turn on the receiver, the receiver checks for a power up file and, if one is present, applies the settings in this file.

Default Settings 9

If the Trimble R7 receiver loses power unexpectedly, when power is restored the receiver tries to return to the state it was in immediately before the power loss. The receiver does not reset itself to defaults or apply any Power Up settings. If the receiver was logging when power was lost unexpectedly, it resumes logging when power is restored.

However, when you turn off the receiver using [P], the receiver behaves as if you pressed [D] to stop logging before you pressed [P]. In this case, when power is restored normally, logging does not begin until you start it manually.

You can use application files to change the settings in the receiver. Sending an application file to the receiver does not necessarily apply the file’s settings; you can apply a file’s settings at any time after sending it to the receiver. You can also define timed application files. A timed application file contains receiver settings, but also includes a date and time when it is automatically activated.

If there is a timed application file on the Trimble R7 receiver, the receiver automatically applies the file’s settings and begins logging (if logging settings are included in the file) at the specified time. If the
