Electrostatic Discharge (ESD)

Note – For detailed information about ESD, refer to the Trimble Service Provider

Reference Manual (P/N 022480-068).

The Trimble R6 receivers were constructed in an ESD-protected environment. Most of the semiconductor devices in the instrument are susceptible to ESD damage.

ESD is generated in many ways. separation of materials, or the normal motion of people working with the device. Depending on the magnitude of the charge, device substrates can be punctured or destroyed by contact with, or by mere proximity to, a static charge. The result can be immediate destruction, early failure of the device, or degradation of device performance.

To prevent static damage or destruction:

• Take adequate precautions when you handle or service equipment that contains static-sensitive devices.

• Only attempt to service the circuitry in a static-sensitive device if you are thoroughly familiar with industry-accepted techniques for handling such devices.

• Always take adequate measures to prevent the buildup of static charge on work surfaces and on persons handling the GPS receiver.

General Information and Safety

Charging the Lithium-ion battery

The 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 three months, charge it before use. To ensure a full charge and to optimize the battery life, leave the batteries to charge overnight.

Disposing of the rechargeable Lithium-ion battery

Discharge the 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.

The RoHS initiative

In July 2006, the European Union restricted the hazardous material content within new products being sold. Primarily this was an effort to reduce lead within products. Many parts within electronic devices contain lead, such as solder on PC boards or within IC's. After the RoHS implementation, manufacturers were required to use alternate materials and soldering methods. Products that were sold before the July 2006 date, have been grand-fathered in, and are not subject to RoHS. Service parts specifically for these products containing lead are permitted as well. Only newly created products intended for sale after the July 2006 date are subject to RoHS.

Trimble R6 / R6 (RoHS) GPS Receivers Service Manual Page 14 P/N 60775-SVC, Revision B

Chapter 1

What RoHS means to Trimble

Trimble has made the commitment to create all new GPS products as lead free and certified RoHS compliant. This includes older products which have been selling prior to RoHS. You will start to see many of the older products converted into RoHS compliant versions. Even though these are older products and it is not required, it is an extremely worthwhile endeavor.

What RoHS means to Service

There are several very complex issues around the RoHS initiative. The Service Provider must understand and follow these rules:

• Only lead free solder may be used on RoHS compliant products. Most GPS Service Providers have been using Silver solder for several years (AG/SN). Make sure you ONLY use Silver solder for ANY GPS products.

• Parts meant for non RoHS products must NOT be used on RoHS products. Use only those parts shown in the part list for a specific product.

• Parts meant for a RoHS product may not be compatible with a non RoHS product. Use only those parts shown in the part list for a specific product. If the part works in both products, the part list will state that.

• Radio doors, radio boards, and Bluetooth must also pass type approval. Some parts may not be used in other products due to non compliance with Country regulations. Use only those parts shown in the part list for a specific product.

General Information and Safety

boards pose special problems as they

• Within the part lists, the general rule to identify whether a product is RoHS compliant or not is to look at the short name. For instance, NetRS, R6, and R8GNSS are non-compliant products. NetRSR, R6R, and R8GNSSR are RoHS compliant (shown by the last letter R).

• It is highly recommended that Service Providers have separate inventory location for lead and lead free parts. This might mean a different cabinet or shelf. It is also highly recommended to have RoHS labels available to attach to the individual part. Green dots are a good solution and will help to quickly identify RoHS compliant parts.

• RoHS service parts will be a phase in process for non RoHS products. Use the original part defined for the non RoHS product first. Once these parts are consumed, the new RoHS part will phase in as long as it is FULLY backwards compatible. The old part numbers will then be inactivated. Please, ALWAYS refer to the latest part list.

• RoHS compliant PC boards may be identified by these symbols:

• In mid 2007, China will launch its own RoHS initiative. The products that have been certified as RoHS compliant will comply with specific country regulations.

COCOM limits

The U.S. Department of Commerce requires that all exportable GPS products contain performance limitations so that they cannot be used in a manner that could threaten the security of the United States. The following limitations are implemented on the Trimble R6 GPS receiver:

• Immediate access to satellite measurements and navigation results is disabled when the receiver's velocity is computed to be greater than 1000 knots, or its altitude is computed to be above 18,000 meters.

Theory of Operation

• The receiver continuously resets until the COCOM situation is cleared.

Although the receiver has a waterproof housing, reasonable care should be taken to protect the unit. Avoid exposure to extreme environmental conditions, including:

• Water immersion

• Heat greater than 65 °C (149 °F)

• Cold less than -40 °C (-40 °F)

• Corrosive fluids and gases

Operating conditions

The receiver is designed to withstand the rough treatment that typically occurs in the field. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.

Warning – Operating or storing the receiver outside the specified temperature range can damage it. See Chapter 2, Specifications.

Chapter 3

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 cellular phones and two-way radios, do not normally interfere with receiver operations.

Avoiding electrical interference

Avoid the following sources of electrical and magnetic noise:

• Gasoline engines (spark plugs)

• Televisions and office computer monitors

• Alternators and generators

• Electric motors

• Equipment with DC-to-AC converters

• Fluorescent lights

Theory of Operation

• Switching power supplies

Major circuit boards/assemblies

Although the receiver has 11 MB of internal data memory, it is the controller (TCU or TSC2) that should be used as the primary data storage for RTK survey styles.

Bluetooth technology offers a cable-free operation when epoch intervals are set to 1 per 5 seconds or longer. If the epoch interval is set to a faster rate (for example, 1 per second), the receiver must be cabled to the controller. The range of Bluetooth communications is about 5 meters (15 feet) depending on external noise or interference levels. In some cases, interference from several Bluetooth capable device in close proximity can cause this distance to decrease. Bluetooth technology is a cable-free system, not a long distance remote control system.

The receiver contains the following five major circuit boards/assemblies:

• Bluetooth-I/O board, page 28

• Radio door assembly, page 29

• Processor board, page 31

• Low Noise Amplifier (LNA) / Spirit antenna patch, page 32

• Keypad assembly, page 32

Bluetooth-I/O board

You can replace this board (P/N 55155-10S RoHS and P/N 55155-00S non-RoHS), which has the following properties and features:

• Port 2 (RS-232 port through a DB-9 connector). Allows data communications and external sensor input or output.

• Port 1 (Lemo-style 7 female connector). Allows data I/O operations. This is the primary port between the receiver and the controller (TCU or TSC2) for cable type operations. It is also the port used to upgrade firmware or options within the receiver. Connecting the receiver to an office computer uses the standard survey download cable (P/N 32345) and AC adaptor (P/N 48800-00 or 30413).

Note – Newer cables and AC adapters are available and are RoHS compatible. However,

P/N 55155-10S is not backward compatible for use in the Trimble R6 receiver. Trimble will not assume any liability for a third-party servicer who uses incorrect parts for a repair.

• Bluetooth TX/RX wireless communications system. Sends and receives data between the receiver and the controller (ACU, TCU, TSC2, or the TSCe with BlueCap module). Includes the TX/RX antenna for Bluetooth. The figure on

page 58 shows the radiation area. Other electronic equipment in use nearby may

interfere with the communications link. Do not add large metallic labels to this area. The Bluetooth primary communications frequency is 2.4 Ghz and is allowed in most countries.

Theory of Operation

• Interface connection between the keypad cable and the processor board.

• Port 1 and 2 protection circuitry (identical to that in the 5800 GPS receiver). A PTC takes a sample of current supplied. If the current is too high (for example, in over-voltage, shorted, or reverse polarity conditions), the device heats up rapidly and causes a crowbar action to shut off supplied power. Remove the power source and correct the problem. The unit automatically resets as the temperature of the PTC decreases to normal.

Caution – The PTC is always in circuit and can withstand a maximum of 35 VDC. If you connect a higher voltage, the PTC will be destroyed and will not protect the receiver. The PTC is extremely useful in that it does not offer a voltage drop like a diode. This is especially important when the primary power source is a battery.

Radio door assembly

A radio door assembly (P/N 57880-XXS, 59400-XXS, 58707-XXS, or 64235-XXS) is present only in radio-equipped versions of the receiver.

• For the Trimble R6 receiver (non-RoHS), use only P/N 57880-XXS or P/N 58707-XXS.

• For the Trimble R6 receiver (RoHS), use only P/N 59400-XXS or P/N 64235-XXS.

Do not interchange radios between receivers.

There are no serviceable parts in a radio door, which must be replaced as an assembly. A few external repairs (for example, the dustcap and the labels) are possible.

In Receive mode, the radio door assembly receives correction information from a transmission source, converts the information into a defined digital format, and sends the information to the processor board. The user can select which frequency, channel spacing, baud rate, and packet type the radio door assembly receives, in the configuration setup.

In Transmit mode (if available), the correction data string is sent from the processor board to the transmitter for broadcast. The radio transmitter generates the carrier frequency and then modulates this in a packet format for broadcast.

Theory of Operation

The customer can select a frequency defined in the transmit frequency list. The customer can also modify any of the receive frequencies, but is not allowed to change the transmit frequencies.

The Service Provider can create a file of customer-specified frequencies to be installed by the customer, and can also directly change the transmit frequencies of a locally-connected GPS receiver.

Each version of the UHF radio door assembly has a frequency range of 20 MHz.

Versi on Frequency range

-62 410–430 MHz

-64 430–450 MHz

-66 450–470 MHz

The highest frequency of one version is the same as the lowest frequency of the next. Consequently, if you select the same channel spacing for both, you can use a version -62 radio door assembly with 430 MHz selected in place of a version -64 radio door assembly with 430 MHz selected, or a version -64 radio door assembly with 450 MHz selected in place of a version -66 radio door assembly with 450 MHz selected.

The radio door assemblies are transmit-capable, although this function is considered an upgrade. The radio door assemblies:

• are compatible with the TRIMMARK™ 3, High Power Base, PDL450, SiteNet450, and any of the TX/RX radios in the older R8, R7, 5800, and 5700 receivers

Chapter 3

• may have compatibility issues with an older radio, such as a 4700, 4800, or TRIMMARK 2e radio

• are not compatible with a TRIMMARK 1 or TRIMMARK 2 radio

Changing the version

Trimble does not recommend that a customer or a Service Provider changes from one version of radio door assembly to another, for the following reasons:

• The internal connector on the radio is not intended for multiple insertions or extractions. It will break.

• The seal integrity of the whole GPS receiver is compromised when the radio is removed. A customer does not have the facilities to test seal integrity.

• Trimble has no way of knowing which radio version is being used for a specific product serial number (SN). This leads to confusion and mistakes, and the very real possibility of the warranty being voided.

• If the unit is outside of warranty, the customer can purchase another radio, which must be installed by the Service Provider. There are hardware limitations to this, so be very careful, especially with the GSM and 900 MHZ doors.

Caution – Because of installation problems and country regulation issues, Trimble does not sell radio doors to end users. Trained Service Providers must comply with country regulations and install the correct radio only in defined and accepted receivers. Installing a radio in a non specified GPS product or device voids any warranty of the radio and of the GPS product. It also subjects the Service Provider to penalties set forth by various government agencies. Trimble shall assume no liability for radios used in non-authorized products.

The key features of each version of the radio door assembly are shown below.

Processor board

Note – This processor board (P/N 53646-01S) is not compatible for use in the Trimble R8,

SPS780, or 5800 receivers. The board is fully backward compatible for use in the Trimble R6 / R6 RoHS / R8 GNSS receivers and will replace P/N 53646-00S.

You can replace this board, which:

• contains all circuitry for the various power supply voltages, and controls the power input and output.

• has the main CPU for interacting with a computer or handheld device.

• down-converts and processes GPS, GLONASS, and WAAS/EGNOS information from the LNA/antenna patch. Enabling GLONASS, signals is optional for the Trimble R6 receiver.

• uses correction information collected by the radio module to correct GNSS information and so increase the accuracy and repeatability of a point.

• has 11 MB of memory which it uses to store program, data, application file, and configuration information.

If you replace the processor board, configure the replacement board to the specific receiver:

1. Make a note of the receiver serial number and part number, and the radio door assembly part number.

2. Contact Trimble for the necessary password(s).

3. Change the serial number from 0000000000 to the serial number of the unit under repair.

4. Install a password option, and configure the board as a Trimble R6 or R8 GNSS.

5. Install any appropriate upgrade options, such as Date option or UHF TX enable.

Low Noise Amplifier (LNA) / Spirit antenna patch

You can replace this assembly—P/N 59153-10S, or P/N 55175-10S (Trimble R6 receiver).

Note – P/N 59153-10S is fully backward compatible with the Trimble R6 receiver, and will

replace P/N 55175-10S.

Each P/N has the following properties and features:

• The antenna and low noise amplifier for reception are presented as raw information to the processor board through two separate semi-rigid coax cables. The L1 cable carries data received from the Satellite L1 transmission (C/A and GLONASS L1 signals). The L2 cable carries data received from the L2 or WAAS satellite transmission.

Note – If the L1 reception fails, the system will not function because L2 reception requires

the L1 signal.

• The semi-rigid coax cables are sold separately.

• To replace the LNA/antenna patch, replace it as an assembly. This LNA/antenna patch is not compatible with earlier Trimble R8, SPS780, or 5800 receivers.

Memory storage

The receiver has 11 MB of internal data memory storage, although the primary memory storage is the TSC2 or TCU controller. For the RTK survey method, the controller must be attached to the rover.

Depending on which version of GPS receiver you have, when the receiver is connected by cable or by Bluetooth wireless technology 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 controls on the receiver. Instead, you use the controller functions to set logging options, to specify file names, and to control when data is stored in job files, which can then be transferred to the office. For more information on logging data from a receiver using a Trimble controller, refer to the user guide for your controller.

To reset the receiver to its factory default settings, make sure that the receiver is turned off and then press and hold the power button

for 15 seconds.

Chapter 3

Power input

The receiver can be powered by its internal battery, by an external power source connected to Port 1, or by both. Typically, one internal Lithium-ion 2.4 Ah battery provides approximately 5 hours of operation during an RTK survey using the internal receive radio. When transmit mode is in use, the operating time is approximately 3 hours.

When external voltage of less than 15 VDC is applied, the receiver turns on automatically. This is different from the earlier Trimble R8, SPS780, or 5800 receivers.

If an external power source is connected to Port 1, it is used in preference to the internal battery. When there is no external power source connected, or if the external power supply fails, the internal battery is automatically used. The receiver system includes rechargeable Lithium-ion batteries (P/N 54344), and a dual battery, 2 Pack Charger (P/N 61114-00). The batteries charge sequentially and take approximately three hours each to fully charge from a full discharged state.

Battery charging and storage

Theory of Operation

Safety

Warning – Use only the specified battery charger to charge the battery pack. Other battery

chargers may cause the battery pack to catch alight or to rupture.

Warning – Never burn or heat the battery. Doing so may cause the battery to leak or rupture. A leaking or ruptured battery can cause serious injury.

Warning – Do not short-circuit the contacts in the battery pack. The battery pack has an auto-reset circuit breaker, but short circuits may cause the battery pack to catch alight or to burn you.

Rechargeable Lithium-ion batteries

The Trimble R6 GPS receivers uses a rechargeable Lithium-ion battery as the primary power source.

Theory of Operation

Charging the battery

Trimble R6 / R6 (RoHS) GPS Receiver

P/N 60775-SVC, Revision B Page 37 Service Manual

Chapter 3

Note – All battery types discharge over time when they are not being used. Batteries also

discharge faster in colder temperatures.

To protect the battery from deep discharge (5 volts or less), the receiver stops drawing power when the battery pack discharges to 5.9 volts. The receiver shuts down with no damage to receiver or battery. (The deep discharge protection circuit can be triggered if a battery with a low charge is left for several weeks.)

To try to recover a battery that has reached the deep discharge level, place it in the 2-pack charger. This may not always succeed. If the battery reaches this deep discharge state, it sets a protection circuit, also called the sleep or protection mode. A Service Provider can “wake up” the battery and recharge it. There is no damage or limiting of the life expectancy on the battery but the customer must replace the battery or send it to a Service Provider to recover it. Trimble recommends the following for optimal performance and to extend the life of the batteries:

• Fully charge all new batteries before use and when the system is first received. The batteries are shipped at less than 100% charge. If you use them in this depleted state, it will reduce their life expectancy. To ensure a full charge, and to optimize the life of the battery, leave it to charge overnight.

Theory of Operation

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

• Keep all batteries on continuous charge in the 2-pack charger when not in use. Batteries may be kept on the charger indefinitely without damage to the batteries.

• Do not store batteries in the external charger unless power is applied. If you must store the batteries, fully charge them before storing, place them in a plastic bag, at room temperature, then fully recharge them at least once every three months.

Battery charging is done externally using the 2-pack charger. You cannot charge the internal Lithium-ion battery by applying more than 15 volts to Port 1. The 2-pack charger is included with all new receiver systems.

Only a Trimble branded battery is authorized for use within Trimble products. Use of any other battery limits or voids any warranty for the product. The battery generally carries a 1-year warranty. Warranty is not offered on non-Trimble batteries, batteries that have been misused (used outside of their stated operating specifications), or for normal wear and tear.

The Lithium-ion battery has a finite number of discharge/charge cycles in its lifetime. As the number of cycles approaches the maximum, the support capacity decreases. A new battery may have 6-hour support capacity, but an older battery may only have 1 hour. This is normal wear and tear. There are many variables when assessing the life of a battery. With average/medium use, the battery should reach 1-hour support time after about 3 years. Using the batteries for UHF transmission reduces this life expectancy to about 2 years.

Power output

The receiver does not output power from either of its two ports. The internal Lithium-ion battery is not charged when external power is applied to the receiver.

Mounting the receiver on a range pole.

Theory of Operation

1. Thread the receiver onto the range pole.

2. Attach the controller bracket to the pole.

3. Insert the controller into the bracket. No cabling is required for a Trimble controller.

Other system components

You can use the following optional components with the receiver.

Radios

Radios are the most common data link for RTK (Real-Time Kinematic) surveying. The receiver is available with an optional internal radio in either the 450 MHz or GSM band. You can also connect an external radio to either serial port, whether the internal radio is installed or not. The receiver supports the following Trimble base radios with the internal 450 MHz radio (assuming each of the receivers has the firmware version to support the communication):

•TRIMMARK™ 3 radio

• TRIMMARK™ IIe radio (limited compatibility)

•SiteNet 450

• PDL450

Trimble R6 / R6 (RoHS) GPS Receiver

P/N 60775-SVC, Revision B Page 39 Service Manual

Chapter 3

•HPB

Internal radio setup

To configure the optional internal radio, use one of the following utilities:

• GPS Configurator utility

• WinFlash utility

You can also change the receiver setting using the Trimble Survey Controller™ software.

For more information, refer to the GPS Configurator Help, the WinFlash Help, or the Trimble Survey Controller User Guide. By default, the internal radio has only a few “test” frequencies installed at the factory. The customer can add receive-only frequencies. To add transmit frequencies directly into a connected unit, the customer must install a file that is generated and sent to them by the Service Provider or Trimble. The UHF Transmit switch must be enabled before you can add transmit frequencies. Use the WinFlash utility to program licensed frequencies before you use the receiver.

Cellular modems and external radios

Theory of Operation

Instead of the internal radio, you can use a cellular modem or external radio as the data communications link. To connect a cellular modem to the receiver, you need the following:

• A receiver

• A cellular modem, or a cellular phone that can transmit and receive data

• A serial (cellular phone-to-DB-9) cable. This cable is supplied with the cellular modem or phone.

Note – For more information, refer to the document Using Cellular and CDPD Modems

for RTK, which is available from the Trimble website.

Port 2 of the receiver supports full RS-232 protocol, and should function correctly with most cellular phone cables. Some cellular units may require custom cabling. For more information on using a cellular modem as a data link, refer to the Trimble Survey Controller User Guide.

GSM cellular radios (P/N 59400-70 and P/N 59400-71) can be installed in the radio bay to provide a completely integrated solution.

To connect an external radio modem to the receiver, you need the following:

• A receiver

• An external radio capable of receiving and decoding Trimble data packets

• A serial cable for either Port 1 or Port 2 of the receiver, as supplied by the radio manufacturer

• A radio mount for the range pole

Chapter 3

Application files

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 the receiver. You can apply an application file's settings at the time it is transferred to the receiver or at any time afterwards.

Special application files

The receiver has three special application files, which control important aspects of receiver configuration.

• 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 option in the GPS Configurator utility. 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.

Theory of Operation

for at least 15 seconds, or use the reset

• 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. When you switch 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 used to set the receiver to a specific configuration whenever the unit is powered up. You can specify that the receiver is reset to defaults before the Power Up settings are applied. This ensures that restarting the receiver always resets it to factory defaults prior to applying the Power Up application file. Alternatively, you can specify that the Power Up settings are applied immediately after the Current application file's settings have been

Trimble R6 / R6 (RoHS) GPS Receiver

P/N 60775-SVC, Revision B Page 41 Service Manual

Chapter 3

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. If you want to use a Power Up application file, you need to create an application file in Configuration Toolbox and make sure that the Auto Power Up file option is selected in the File page. When you transfer this file to the receiver, it is transferred with the name Power_up.cfg, and becomes the new Power Up file. The Power Up file is the only special application file that you can overwrite or delete from the receiver.

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, you can save the file on the computer or in the receiver, then open it later and apply its settings.

Storing application files

You can store application files that you create in Configuration Toolbox on both your receiver and 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:

Theory of Operation

• 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 identically configure multiple receivers

• you can use an existing application file as a template to create other application files with similar settings.

Naming application files

The file name that you use to store the application file in the computer and the name under which the file is stored in the receiver are always the same. This makes recognizing and keeping track of your application files easier. If you change the name of the file on the receiver, this changes the file name used to store the application file on your computer. Similarly, if you change the file name on the computer, the name of the file in the receiver will change.

version of TX to RX.

– Check for a non-matching packet type

(CMR vs CMR+).

– Check that the Receive Radio Ant is

installed.

– Check the frequency of TX is the

same as RX.

– Check the power source for TX while

under load.

– Check that the TX resolution

bandwidth is the same as RX radio (12.5 kHZ or 25 kHZ).

– Make sure that TX has the same

wireless baud rate as RX.

Poor radio reception – Is the Rover beyond the radio range

of the transmitter.

– Poor terrain (trees, hills, or buildings)

can decrease the transmit signal strength (the range between the base and the rover).

– Try another “rubber duck” radio

antenna.

– Check that the TX Ant is OK.

– Try another RX radio. If not OK, you

have a TX failure. If OK, you have a problem on the RX radio side. Watch closely the original RX radio operation as well as the substitute. If both RX radios perform poorly, there is probably external noise. Try another frequency.

– Check all RX radio parameters

carefully.

– Try another TX radio.

– Check the power source for TX while

under load.

– Do a 15-second reset.

– Do a 30-second reset.

– Reflash the firmware.

– Review the area for high noise

generation (cellular phones, ambulance, police, hospital, high power lines, radar, commercial radio transmitters, other surveyors, etc.).

– Many poor radio reception problems

are due to external influences. Move the RTK system to a different location. This is not a system failure.

Use and care

Underside of the receiver

Warning – Operating or storing the receiver outside the specified temperature range can

damage it. For details, see Chapter 2, Specifications.

The receiver can withstand the rough treatment that typically occurs in the field. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.

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 (approximately 1300 ft) of powerful radar, television, or other transmitters. Low-power transmitters, such as those used in cellular phones and two-way radios, do not normally interfere with receiver operations.

Radios allowed in receivers

The door colors will be different for GPS receivers used in different markets. The following applies:

Radio Door Assemblies

Comments

These new radios will be released soon. These are non-RoHS versions, currently used only on the Trimble R6 non-RoHS receiver.

These new radios will be available soon. They are for use in the Trimble R6 RoHS receiver only.

• Continue to use the 53620-XXS series of radios for older receivers.

• Continue to use the 57880-XXS radios for Trimble R6 / R8 GNSS, and SPS880 receivers.

•Use only the 59400-XXS radios for the Trimble R8 GNSSR receivers.

• Use the 58707-XXS radios for the Trimble R6 non-RoHS receiver

• Use the 64235-XXS or 59400-XXS radios for the Trimble R6 RoHS receivers.

• Never use older radios in newer receivers.

• Never use a leaded part in a RoHS compliant device. Follow the part lists carefully for each receiver and do not substitute parts that look the same.

Shielding methods

Radio doors throughout the generation changes of 5800 to Trimble R8 GNSSR receivers use four different methods of RF shielding. Most of these shielding methods are applied to the radio door. However, method 3 has the shield applied to the endoskeleton of the GPS receiver and poses problems. The Trimble R6 receiver uses shield method 4.

Method 2 is most effective for greater range between the base and the rover.

Trimble R6 / R6 (RoHS) GPS Receiver Service Manual Page 86 P/N 60775-SVC, Revision B

Chapter 6A

Method 1

A thick EMI/RFI foam pad glues to the radio door. The pad contacts and grounds the radio to the endoskeleton.

Radio Door Assemblies

Method 2

Primarily used in the -44 versions of radio doors, this is a metal plate with several copper fingers, which contact the endoskeleton, and ground the radio to the GPS receiver. For better performance, you can use this method on other -4X radio versions.

Copper fingers

Trimble R6 / R6 (RoHS) GPS Receiver

P/N 60775-SVC, Revision B Page 87 Service Manual

Chapter 6A

Method 3

A thin EMI/RFI foam pad is glued to the endoskeleton. Two PEM nuts on the radio door are the primary contact to the endoskeleton EMI pad, which the radio contacts and grounds to.

This method offers special problems. If you change the radio, you must use only one shield method:

• If there is no EMI foam pad in the endoskeleton, make sure that the radio door employs shield method 1, 2, or 4. Most new radio doors will use method 4.

• If there is an EMI foam pad installed in the endoskeleton, make sure that the radio door does not use shield method 1, 2, or 4. Since you are probably replacing the radio door, it is very likely that it uses shield method 4. In this case, you must remove the EMI foam pad from the endoskeleton and clean the surface thoroughly before installing the new radio.

Chapter 6A

Method 4

This is an L-shaped metal bracket with an EMI pad, mounted on the back of the radio door. Make sure that you do not also use shield method 3. If the radio door has the L-shaped bracket, remove the EMI/RFI foam pad from the receiver endoskeleton. If two foam pads are installed, the radio is not correctly grounded and will have poor receive range. Transmit distance is not affected, although GPS jamming could occur.

Note – There is no way to change from other shielding methods to this method.

Integrated GSM radio: Overview

Note – These radio door assemblies are not compatible with the SPS880, SPS780, or 5800

GPS receivers.

The Trimble R6 receiver can be purchased with an integrated GSM cellular modem that provides an alternative method for RTK corrections.

A special radio door assembly contains a cellular modem that can transmit and receive using a cellular phone service carrier. The customer selects a local cellular phone service carrier to provide RTK corrections. The service must offer GSM CSD operation.

The Trimble R6 receiver with a GSM cellular modem is shipped without a SIM card. The customer buys a SIM card, either from a local cellular phone service carrier or from the Service Provider. The customer cannot install, test, or activate the cellular service on the GPS receiver. Only the Service Provider or Trimble may do this. The SIM card can be installed once and cannot be removed.

Trimble R6 / R6 (RoHS) GPS Receiver

P/N 60775-SVC, Revision B Page 89 Service Manual

Chapter 6A

GSM door activation requirements

The customer chooses their preferred cellular phone service carrier to operate the Trimble R6 receiver. The cellular phone service carrier must be able to provide:

• A GSM service that supports CSD (circuit switched data).

• A comprehensive system for adequate coverage.

• A 3-volt SIM card (other voltage SIM cards will not work).

• A calling plan selected by the customer. Billing information and account setup is the responsibility of the customer, unless you choose to offer this service for your customers’ convenience.

In most cases the SIM card is activated when the cellular subscription is completed. The T-mobile cellular phone service carrier has been used with the Trimble R6 receiver but the customer is not limited to this one carrier.

Charging for the GSM door installation/activation

You can charge Trimble for a maximum of two hours of labor for the installation and activation of a SIM card into a brand new Trimble R6 receiver.

Radio Door Assemblies

Charge the customer for the cellular phone activation (if you purchased a SIM card for the customer), and give full account details to the customer. Trimble recommends that you record the product serial number, GSM IMEI number, and other important information for future service needs.

Installing a GSM door: Overview

Note – The GSM door is not compatible with the SPS780/781/880/881 receivers or earlier

Trimble R8 receivers with hardware version 1.

The customer or dealer gives the Service Provider a Trimble R6 receiver with the GSM radio door assembly attached. The customer, or a dealer who is not an Authorized Service Provider, is not authorized to remove the GSM radio door assembly.

Note – The GSM (cellular) feature requires a radio door assembly that has a P/N ending

in -70 or -71.

Step 1: Record the GSM IMEI number

The cellular phone service carrier will probably require the GSM IMEI number. This is a unique identifier on each GSM module.

To retrieve this information from the receiver, do one of the following things:

• Remove the GSM radio door assembly and view the GSM IMEI label on the module.

Trimble R6 / R6 (RoHS) GPS Receiver Service Manual Page 90 P/N 60775-SVC, Revision B

Chapter 6A

• Use the WinFlash utility:

a. Make sure that the receiver has the firmware version 3.10 or later installed; or

firmware version 3.50 or later for the RoHS-compatible receiver.

b. Run the WinFlash utility.

Chapter 6A

Step 2: Verify that the GSM (cellular) option switch is enabled

• This option switch is not, and cannot be, enabled on an SPS880 GPS receiver.

•It is enabled as a standard option on an Trimble R6 receiver.

To enable the GSM (cellular) option switch, a password from Trimble is required. To obtain this, you need to know the receiver P/N and SN.

Note –

- Firmware version 3.10 or later must be installed; or firmware version 3.50 or later for the RoHS-compatible receiver. Use the WinFlash utility to check this.

- The GSM (cellular) feature requires a radio door assembly that has the P/N ending in -70 or -71.

To determine which configuration options are enabled, use the WinFlash utility. In WinFlash, the GSM (cellular) switch is called “cellular”:

For more information, contact trimble_support@trimble.com.

Step 3: Installing the SIM card

a. Arrange with the customer which SIM card to use in the receiver. This could be

a SIM card provided by the customer, or one that you purchase for them. Trimble recommends that you buy and activate the SIM card for the customer. You must have all customer billing details available for the cellular phone service carrier to start billing. Trimble also recommends that you have a SIM card for service testing purposes.

b. Remove the GSM radio door assembly, install the SIM card and then reinstall

the GSM radio door assembly.

Chapter 6A

Step 4: Testing the receiver

a. To test the receiver, use a WinFlash diagnostic tool. Alternatively, use the

TSCe controller to make and receive a call.

b. Make sure that you have a base GPS receiver with an active cellular phone for

data transmission. Run a short system test (see page 125) to verify that the GPS data set is being corrected by the GSM cellular phone. The unit must pass the system test.

c. Perform the Seal Integrity test, see page 176.

Installing a GSM cellular or UHF Transmit door assembly

Follow these guidelines:

• Only radio doors that have P/N 57880-7XS (non-RoHS) or P/N 59400-7XS (RoHS) may be used in the Trimble R6 receivers.

• A few early versions of the Trimble R6 receiver (P/N 60275-XX), may have used an EMI pad (P/N 51509-00S) attached to the endoskeleton. In all newer radio doors, there is an L-shaped grounding bracket. If you find an L-bracket on the radio door, you must remove the EMI foam pad from the endoskeleton. Do not use both shielding methods (foam pad and L-bracket) together.

• If the radio door does not have an L-bracket that touches the endoskeleton, carry out the following steps to install the EMI foam pad.

Testing GSM Cellular

To set up a TSC2 controller to make and receive calls, you need a TSC2 controller that is running the Trimble Survey Controller software version 12.00 or later. Alternatively, you can use a TSCe controller that is running the Trimble Survey Controller software version

10.80, and that has a BlueCap module attached.

Registering the Trimble R6 Bluetooth device with the controller

1. Select Start / Settings / Control panel / BT device property.

2. Make sure that the box next to the Enable BT check box is selected.

3. Select Scan. The Trimble R6 receiver appears in the Untrusted column.

4. Double-click that item and then select No. The Trimble R6 receiver appears in the Trusted column.

5. Click

OK.

Connecting to the receiver and getting CSQ

1. Start the Trimble Survey Controller software.

2. Select Config / Controller / Bluetooth.

3. In the Connect to GPS dialog, select the receiver that is under test and then click

Accept. The Trimble R6 icon appears on the right of the Trimble Survey Controller

screen.

4. Select Instrument / GSM status. A screen shows details of the GSM service carrier and of the CSQ (represented by a maximum of seven bars).

5. Make sure that the CSQ is acceptable. For a voice call, the relationship between CSQ and performance is similar to that of a cellular phone.

Setting up a survey style

1. From the Trimble Survey Controller main screen, select Config / Survey Styles / RTK / Rover Radio.

2. Enter

3. Select GSM Dial Up.

4. For Name to dial, click the

5. Give the dial-up a known working local telephone number and then press Enter. The new entry with a name and phone number appears on the menu.

6. Select that entry.

7. Leave all other settings as they are and then select Accept / Store.

Creating a new job to make a call from the receiver through the controller

1. From the Trimble Survey Controller main screen, select Files / New Job.

2. Give the new job a name, select Enter and then select Accept.

3. Select Survey / RTK.

4. Start the survey. The receiver should make a call to the chosen phone number. If the phone rings, the SIM card has been installed correctly and the service set up properly. Cancel the operation to hang up the phone.

To delete the newly created job, use the operating system’s Windows Explorer.

Radio Door Assemblies

The GSMcheck utility

GSMcheck is a utility that fully tests a GSM radio door installed in a Trimble R6 receiver. You can use it instead of the TSC2 test. The test validates that the SIM card is correct and installed properly. It tests the GSM network connection at the location of test. It also validates two way communication between the GSM door and the GSM provider.

You must have:

• The GSM door installed in the receiver

• A valid and active SIM card installed in the GSM door

• The cellular option enabled

Running the test

1. If necessary, download the GSMcheck utility from the Trimble Partners website and then install it on the office computer.

2. Use a serial cable to connect the receiver to Com1 on the computer. You can use either the DB-9 port or the Lemo port.

3. Turn on the receiver.

4. On the computer, double click GSMcheck.exe to start the program:

5. Select or enter the following, according to your specific requirements:

a. Region: Rest of World (P/N XXXXX-70) or Americas (P/N XXXXX-71)

b. Test Phone Number To Call: Can be left blank. Otherwise, the program tells the

modem to call the number. The user needs to be able to pick up and then hang up the call.

Radio Door Assemblies

c. APN Parameters: To make a GPRS data connection, certain parameters are

required. The user enters these into the controller, which sets them in the modem. Possible issues are that the user has not done this, so the settings are not present, or the service operator wants to make a test with their SIM and their GPRS service.

To make the test program use the supplied values, select the Override Module’s APN Settings check box. Even if this is not selected, if the modem has no settings of its own, the values entered here are used if the operator responds “Yes” when prompted. The original settings are restored.

The Context ID is always “1” and the Protocol is always “IP”.

Use your own username/password and PIN settings.
