!!!!WARNING - This alert warns of a potential hazard which, if not avoided, could result in severe

injury or even death.

!!!!CAUTION - This alert warns of a potential hazard or unsafe practice that could result in minor

injury or property damage or irretrievable data loss.

NOTE – An absence of specific alerts does not mean that th

ere are no safety risks involved.

Use and care

This product is designed to withstand the rough treatment and tough environment that typically occurs in construction applications. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.

!!!!CAUTION - Operating or storing the receiver outside the specified temperature range can

damage it.

Regulations and safety

Some receiver models with base station capability contain an internal radio-modem for transmission or can transmit through an external data communications radio. Regulations regarding the use of the 410 MHz to 470 MHz 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. For licensing information, consult your local Trimble dealer.

NOTE – The Alloy uses the 403 MHz to 473 MHz frequency ran

ge.

All Trimble receiver models described in this documentation are capable of transmitting data through Bluetooth wireless technology.

Bluetooth wireless technology, and 900 MHz radio-modems and 2.4 GHz radio-modems operate in license-free bands.

NOTE – 900 MHz radios are not used in Europe. The frequenc

y range of 900 MHz is not marketed in

Brazil.

Before operating a Trimble receiver or GSM modem, 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 the receiver for the location or country of use.

For FCC regulations, see Notices.

Alloy GNSS reference receiver User Guide 5

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 radio-modem 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.

Exposure to radio frequency radiation

The Alloy (with internal 450 MHz radio operating in base station transmit mode). Note the safe distance is 40cm for RF Exposure.

For 450 MHz radio

Safety. Exposure to RF energy is an important safety consideration. The FCC has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment as a result of its actions in General Docket 79-144 on March 13, 1986.

Proper use of this radio modem results in exposure below government limits. The following precautions are recommended:

•

DO NOT operate the transmitter when someone is 40 cm of the antenna.

• DO NOT operate the transmitter unless all RF connectors are secure and any open connectors are properly terminated.

• DO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere.

•

DO NOT co-locate (place within 45 cm (17.7 inches)) the radio antenna with any other transmitting antenna.)

• All equipment must be properly grounded according to Trimble installation instructions for safe operation.

• All equipment should be serviced only by a qualified technician.

For license-free 900 MHz radio

!!!!CAUTION - For your own safety, and in terms of the RF exposure requirements of the FCC,

always observe these precautions:

• Always maintain a minimum separation distance of 25 cm (9.8 inches) between yourself and the radiating antenna.

• Do not co-locate the antenna with any other transmitting device.

NOTE – 900 MHz radios are not used in Europe.

Alloy GNSS reference receiver User Guide

For Bluetooth radio

The radiated output power of the internal Bluetooth wireless radio and the Wi-Fi radio included in some Trimble receivers is far below the FCC radio frequency exposure limits. Nevertheless, the wireless radio(s) shall be used in such a manner that the Trimble receiver is 25 cm or further from the human body. The internal wireless radio(s) operate within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community. Trimble therefore believes that the internal wireless radio(s) are safe for use by consumers. The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices such as mobile phones. However, the use of wireless radios may be restricted in some situations or environments, such as on aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before turning on the wireless radio.

Installing antennas

!!!!CAUTION - For your own safety, and in terms of the RF exposure requirements of the FCC,

always observe these precautions:

• Always maintain a minimum separation distance of 25 cm (9.8 inches) between yourself and the radiating antenna.

• Do not co-locate the antenna with any other transmitting device.

!!!!WARNING - The GNSS antenna and its cabling should be installed in accordance with all national

and local electrical codes, regulations, and practices. The antenna and cabling should be installed where they will not become energized as a result of falling nearby power lines, nor be mounted where they are subjected to over-voltage transients, particularly lightning. Such installations require additional protective means that are detailed in national and local electrical codes.

Trimble receiver internal radios have been designed

to operate with the antennas listed below. Antennas not included in this list are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. To reduce potential radio interference to other users, the antenna type and its gain should be an approved Trimble antenna, so that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication.

About the Alloy GNSS reference receiver

The Alloy GNSS reference receiver is a multiple-frequency GNSS receiver. It can track all GPS signals (L1/L2/L5) as well as GLONASS (L1/L2). You can use the front panel of the receiver or an office computer to configure the receiver, access files, and publish data files to a company intranet or to the Internet. The Alloy receiver makes it easy for you to set up a powerful, flexible, and reliable reference station for continuous operation.

The Trimble Alloy receiver is designed to serve in all common geodetic reference receiver roles. It can be the main component in a continuously operating reference station (CORS), streaming data to Trimble GNSS Infrastructure software. It can also work well as a campaign receiver prior to permanent deployment. The Alloy makes an excellent portable RTK base station with its internal battery. This receiver also has specialized capabilities that make it an excellent reference receiver for scientific applications.

Receiver Overview

In this chapter:

 Receiver framework  Alloy receiver features  Use and care  Electronic interference  COCOM limits  Keypad and display  Rear connectors

This chapter introduces the Trimble Alloy GNSS reference receiver. This receiver makes it easy to set up a powerful and reliable Continuously Operating Reference Station (CORS) or to collect data from temporary field locations.

The Alloy receiver is ideal for the following infrastructure applications:

• Use as part of a GNSS Infrastructure

network in conjunction with Trimble GNSS Infrastructure software.

• Use as part of a permanent reference

station with or without supporting software.

• Use a temporary field base station to

broadcast RTK corrections and collect observations for postprocessing.

• Use as a scientific reference station

collecting data for atmospheric or seismological studies.

Alloy GNSS reference receiver User Guide

Receiver framework

The Alloy receiver integrates the latest multi-frequency GNSS technology into a specialized processing and communications framework. The receiver can operate as a standalone reference station or it can be integrated into a scalable network.

With Internet Protocol (IP) as the primary communications method, you can use public domain tools, such as a web browser and FTP client, to configure the receiver and access logged data files.

Note – All references to the Internet are intended to mean either a Wide Area Network (WAN) or a Local Area Network (LAN) connection.

You can enforce multiple levels of security, from a completely open system that allows anonymous access to all features, to a secured system that requires a password protected login for configuration changes and/or file access.

Use the network management features to create a base configuration with a variety of operating modes. You can then enable those modes as necessary instead of switching the global state of the receiver from one mode to another. For example, you can configure a number of streaming services with different configurations (such as measurement intervals or smoothing controls) on different TCP or UDP ports. To activate one or more modes, open the connection to the specific port. This allows multiple clients to access any given streaming service.

These features and many more, shift the model of a GNSS receiver toward the concept of a “network appliance”.

The network appliance concept

Traditionally, a GNSS receiver has one operator. That person is the only user of the receiver so they can change settings without affecting other users.

With the Alloy receiver, an operator can configure a receiver once, and then make it available, as a network appliance, for general use by one or more users (or clients).

This network appliance concept lets you set up the receiver to provide one or more services that one or more users can access through a Local Area Network (LAN) or a Wide Area Network (WAN), such as the Internet. Once the receiver is set up, you need make only minimal changes, if any, to the receiver configuration.

When the receiver is operating as a network appliance, it provides services to all users attached to the receiver through the network.

Different streamed services may be configured on different ports, for example, with differing data rates or smoothing configurations. To obtain a service, the client has only to connect to a specific port. In this way, most users do not need to control the receiver. Changing global settings, such as masks, will affect all users of all services. However, the comprehensive set of controls that have been provided for streamed service and data logging configuration avoids global changes for the majority of applications.

Alloy services

The Alloy receiver can provide one or more streaming or query services over a RS-232 serial port or a TCP/IP port:

• Streaming service

Anyone with authorized access can obtain streamed information, such as GNSS measurements or RTCM corrections, without having to control or issue commands to the receiver. The client simply connects to the port that is streaming the required information. Normally the port should be set to Output only mode so multiple users can connect to receive correction data.

• Query service

This allows bi-directional communications between the receiver and another application. All ports act as query ports unless Output only mode is selected. When Output only mode is selected, it also means the receiver is more secure; especially if it is on the Internet. Multiple users can connect simultaneously to a single port as long as it is set to Output only mode.

Multiple users can connect simultaneously to a single port as long as it is set to Output only mode.

Use and care

This product is designed to withstand the rough treatment and tough environment that typically occurs in CORS installation. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.

CAUTION – Operating or storing the receiver outside the specified temperature range can damage it.

For more information, see Chapter 8, Specifications.

Electronic interference

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 locating the receiver or antenna within 400 meters of powerful radar, television, or other transmitters or GNSS antennas. Low-power transmitters, such as those in cell phones and two-way radios, normally do not interfere with receiver operations.

COCOM limits

The U.S. Department of Commerce requires that all exportable GNNS 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 this product:

• Immediate access to satellite measurements and navigation results is disabled when

the receiver velocity is computed to be greater than 1000 knots, or its altitude is computed to be above 18 000 meters. The receiver GNSS subsystem resets until the COCOM situation clears. As a result, all logging and stream configurations stop until the GNSS subsystem is cleared.

Batteries and Power

In this chapter:

External power Battery safety Battery performance Charging the Lithium-ion battery Storing the Lithium-ion battery Removing the rechargeable Lithium-ion battery

The Alloy GNSS receiver uses an internal rechargeable Lithium-ion battery, which can be replaced only at an Authorized Trimble Service Center.

The receiver can also be powered by an external power source that is connected to either of the Lemo ports.

The operational time provided by the internal battery depends on the type of measurement and operating conditions. Typically, the internal battery provides up to 12 hours operation.

Note – All battery operational tests are carried out with new, fully charged batteries at room

Alloy GNSS reference receiver User Guide

temperature, tracking both GPS and GLONASS satellites while storing and streaming data at 1 Hz. Older batteries, at temperatures significantly higher or lower than room temperature, will have a reduced

performance. Power consumption increases with an increasing number of actively tracked satellites and well as increasing observation and storage rates.

External power

The receiver uses an external power source in preference to its internal battery. If the receiver is not connected to an external power source, or if the external power supply fails, the internal battery is used.

The applied external power must offer between 9.5 V and 28 V DC and must be able to supply at least 5 W of power. The receiver's internal battery will only charge when the external voltage is above 12 V DC. Trimble recommends that external supply voltage be above 12 V DC for long-term installations. This will ensure that the internal battery is charged and ready to compensate for power supply disruptions.

While carrying out static measurements for postprocessed computations using the internal memory, if no external power is supplied and the internal battery is drained, the receiver shuts down. No data is lost and when power is restored, the receiver restarts in the same status as it was when power was lost.

If for some reason you do not want to use the internal battery as an uninterruptable power supply, you may disable this feature in the Web user interface. See Chapter 6 for details on the configuration setting.

WARNING – The external AC power adapter and its associated power cord and plug are not

intended to be installed outdoors, nor in a wet location.

WARNING – Do not power the receiver through external power when operating in a wet

environment or an environment that may become wet. The power input connections must be sheltered.

WARNING – When you apply DC voltage to this product through the Lemo connector, the DC

voltage must be limited to 28 V DC +0% under both normal and single fault conditions. This product may present an electrical hazard if the recommended input voltage is exceeded.

Alloy GNSS reference receiver User Guide

Battery safety

The receiver is powered by a rechargeable internal Lithium-ion battery. Charge and use the battery only in strict accordance with the instructions below.

WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery can cause an

explosion or fire, and can result in personal injury and/or property damage. To prevent injury or damage: – Do not use or charge the battery if it appears to be damaged. Signs of damage include, but are not limited to, discoloration, warping, and leaking battery fluid. – Do not expose the battery to fire, high temperature, or direct sunlight. – Do not immerse the battery in water. – Do not use or store the battery inside a vehicle during hot weather. – Do not drop or puncture the battery. – Do not open the battery or short-circuit its contacts.

WARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be leaking.

Battery performance

To optimize battery performance and extend battery life:

• Fully charge all new batteries before use.

• Batteries perform best when they are not used at extreme temperatures. The receiver is

designed to operate at –40 °C to +65 °C (–40 °F to +149 °F). However, operation at temperatures of less than 0 °C (32 °F) can cause a rapid drop in battery life.

• Do not allow a battery that is in storage to discharge to below 5 V.

Alloy GNSS reference receiver User Guide

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 three months, charge it before use.

The internal battery charges fully in 24 hours when connected to a suitable power source.

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 within the Alloy receiver. The battery can only be removed by an authorized Trimble Service Center.

Storing the Lithium-ion battery

If you must store a Lithium-ion battery for long periods, make sure that it is fully charged before it is stored, and that you charge it at least once every three months while it is stored.

Do not allow a battery that is in storage to discharge to below 5 V. A battery that reaches deep discharge level (5 V or less) cannot be recharged and must be replaced. (To protect a battery that is in use from deep discharge, the receiver switches power sources or stops drawing power when the battery pack discharges to 5.9 V.)

All batteries discharge over time when not in use, and they discharge faster in colder temperatures. Do not store the receiver at temperatures outside the range –40 °C to +70 °C (–40 °F to +158 °F).

The receiver has an internal Lithium-ion battery. The internal battery will only charge from an external power source that delivers more than 12 volts, for example, an AC power adaptor. The receiver is supplied with a mains power supply unit that recharges the battery inside the receiver when it is connected through the adaptor to either of the Lemo ports. When you use the receiver in a long-term deployment, Trimble recommends that you use this power supply or another that

Alloy GNSS reference receiver User Guide

provides at least 12 V DC at all times to keep the internal battery charged. This will ensure that the internal battery provides an uninterrupted power supply that will keep the receiver operational for up to 15 hours after a power failure.

Keep all batteries on continuous charge when not in use. You can keep batteries on charge indefinitely without damage to the receiver or to the batteries.

Removing the rechargeable Lithium-ion battery

The internal Lithium-ion battery should be removed only at an authorized Trimble Service Center. If the battery is removed at an unauthorized service center, the remaining warranty on the product will be void.

Setting up the Receiver

In this chapter:

 Setup guidelines  Connecting the receiver to external

devices

 Installing the tripod clip

This chapter describes best practices for setting up the equipment, and outlines the precautions that you need to take to protect the equipment. It also describes how to connect the receiver to external devices.

The antenna installation guidelines offered here are the minimum standards: When installing a geodetic antenna to gather precise observation data, always follow recommended CORS installation practices to the greatest extent possible.

Alloy GNSS reference receiver User Guide

Setup Guidelines

When you set up the receiver, follow these guidelines.

Environmental Conditions

The receiver has a waterproof housing. However, you should take reasonable care to keep the unit dry.

To improve the performance and long-term reliability of the receiver, avoid exposing the receiver to extreme environmental conditions, such as:

• Water

• Heat greater than 65 °C (149 °F)

• Cold less than -40 °C (-40 °F)

• Corrosive fluids and gases

Sources of Electrical Interference

Avoid locating the GNSS antenna near the following sources of electrical and magnetic noise:

• Gasoline engines (spark plugs)

• Televisions and computer monitors

• Alternators and generators

• Electric motors

• Equipment with DC-to-AC converters

• Fluorescent lights

• Switching power supplies

• Arc welding equipment

Uninterruptible Power Supply

Trimble recommends that you use an uninterruptible power supply (UPS) to power the receiver. The internal battery can also operate as a UPS for up to 15 hours. A UPS protects the equipment from power surges and spikes, and keeps the receiver running during short power outages.

Alloy GNSS reference receiver User Guide

Items operating with the receiver, such as an Ethernet switch, should also be on a UPS to provide uninterrupted operation.

For more information, contact your local Trimble dealer.

Lightning and surge protection

Trimble recommends that you install lightning protection equipment at permanent sites. All connections to the receiver should have surge protection. Typically, the minimum protection should include a surge protector in the antenna feed line, on the Ethernet connection between the receiver and the local area network, as well as on the receiver's power supply system. If serial devices are attached to the receiver, those serial connections should also be provided with surge protection. Also, protect any communications and power lines at building entry points. If you use other antennas, such as a radio modem that distributes real-time correction messages or a lastmile radio, install surge protection on those antenna feeds as well.

No surge protection devices can offer protection unless they are connected to an excellent ground using very low impedance conductors. Equipment damage caused by electrical surges occurs in many permanent installations even though surge protection is in place. Commonly, this is because the grounding system used was designed to protect against AC electrical hazards rather than to dissipate the sudden, high current surges caused by lightning. Please consult with a lightning protection expert or research the topic when planning permanent installations.

For more information, contact your local Trimble Infrastructure dealer, or go to the websites of surge protection and grounding system manufacturers. Trimble customers have reported good results when using products from the following manufacturers:

• Polyphaser (www.polyphaser.com)

• Huber and Suhner (www.hubersuhner.com)

• Harger (www.harger.com)

• Hyperlink Technologies (www.hyperlinktech.com)

Placing the antenna

The antenna location will have a significant effect on the quality of your Alloy receiver's performance. In temporary developments it may not always be possible to set up on an ideal location with an excellent sky view. However, when installing a permanent station, be sure to plan the antenna location and mounting system carefully.

The general requirements for the antenna location and mount are:

Alloy GNSS reference receiver User Guide

• Clear sky from the zenith to the horizon to a 100 m (328 feet) radius, in all directions (360

degrees).

• Mounted 1.5 m (5 feet) above any nearby signal reflectors.

• Separation of at least 300 m (984 feet) from radio signal transmitters.

• Mount stability that is not influenced by thermal expansion, wind loading, or soil

expansion/contraction.

For additional information on this topic, research the reference antenna installation guidelines published by:

• the US National Geodetic Survey

(http://www.ngs.noaa.gov/PUBS_LIB/CORS_guidelines.pdf)

• the International GNSS Service

(http://igscb.jpl.nasa.gov/network/guidelines/guidelines.html)

Connecting the receiver to external devices

You can connect a Alloy receiver to the following devices:

• GNSS antenna

• Dial-up modems

• Radio modems

• Meteorological and tilt sensors

GNSS Antenna

The Alloy receiver provides a TNC-type female connector for connecting to an antenna. The receiver is intended for use with a Zephyr™ Geodetic Model 2 antenna or a Trimble GNSS Choke Ring antenna.

Antenna Cabling

Many permanent GPS installations have unique cabling requirements. Depending on the available infrastructure, you may need to mount the antenna a substantial distance from the receiver.

The Alloy receiver can withstand a loss of 12 dB between the antenna and the receiver. The degree of loss in a coaxial cable depends on the frequency of the signal passing through it. The following table lists some common types of cable and the maximum length you can use before you need an inline amplifier.

Alloy GNSS reference receiver User Guide

Cable type Maximum length for use without an inline amplifier LMR-400 70 m (230 ft)

LMR-500 85 m (280 ft) LMR-600 106 m (350 ft) Heliax LDF4-50 165 m (540 ft) Heliax. LDF4.5-50 225 m (740 ft)

Dial-up modems

The receiver can make automated dial-out connections to an Internet service provider. To set up the receiver to do this, in the Web interface select Network Configuration/PPP.

You can set up a streaming service, such as RT17/RT27 raw GNSS data, CMR™, or RTCM corrections over a serial port. When using a modem on the serial port, the modem itself must perform the auto-answer function.

Radio modems

You can connect the receiver to an external radio through the Lemo ports or the 9-pin serial port, whether or not the Ethernet port is in use. Trimble radios are supplied with the required cables to connect to the Lemo ports. The Alloy receiver supports the following Trimble base radios:

• TRIMMARK™ 3 (firmware 1.26 or later)

• Trimble HPB450

• Trimble PDL450

To use an external radio with the receiver, you need an external power source for the radio. Configure the external radio separately, using the configuration program for the external radio. To configure the Alloy receiver for RTK operation, you must do all of the following:

• Enable the RTCM or CMR RTK corrector stream on the selected serial port.

• Set the reference station coordinates and broadcast ID using the front panel of the

receiver or the Web user interface.

Meteorological and tilt sensors

You can connect an external meteorological or tilt sensor to any of the three available serial ports on the Alloy receiver.

The sensor responds to a request for information. The request and the response are time tagged and are entered into the Alloy receiver's stored files and streamed observation data.

Alloy GNSS reference receiver User Guide

Note – The sensor's serial configuration must include 8 data bits. Some sensors default to 7 data bits and this is incompatible with the Alloy receiver.

Supported sensors include the following:

• Paroscientific Met3, Met3A, Met4, and Met4A

• Vaisala PTU300

• Applied Geomechanics D700 and MD900 series

The I/O Configuration / Port Configuration menu allows you to enter the serial port settings and control commands for a meteorological/tilt sensor.

Other external devices

For all other external devices, connect to a suitable communications port and then configure that port for the connected device.

Installing the tripod clip

For campaign operations or temporary base deployments, the standard mounting base can be replaced with a tripod clip:

1. Remove the standard mounting base by unscrewing the four bottom screws that are

located beneath the rubber end cap trim.

2. Use the two provided screws to attach the tripod clip to the two holes located at the

bottom of the front panel of the receiver.

You can configure the Alloy receiver to perform a wide variety of functions. This chapter describes the configuration methods other than the front panel display, and explains when and why each method is used.

The WinFlash utility described in this chapter is used primarily to update the receiver firmware and configure the Ethernet settings in the Alloy receiver.

Alloy GNSS reference receiver User Guide

Configuring Ethernet settings

The receiver has an Ethernet port in order to connect to an Ethernet network. You can use the Ethernet network to access, configure, and monitor the receiver. No serial cable connection to the receiver is necessary.

The receiver has the following Ethernet settings:

• IP setup: Static or DHCP

• IP address

• Netmask

• Broadcast

• Gateway

• DNS address

• HTTP port

•

The default setting for the HTTP port is 80. The HTTP port is not assigned by the network. HTTP port 80 is the standard port for web servers. This allows you to connect to the receiver by entering only the IP address of the receiver in a web browser. If the receiver is set up to use a port other than 80, you will need to enter the IP address followed by the port number in a web browser.

Example of connecting to the receiver using port 80: http://169.254.1.0

Example of connecting to the receiver using port 4000: http://169.254.1.0:4000

The default setting of the receiver is to use DHCP. Using DHCP enables the receiver to automatically obtain an IP address, Netmask, Broadcast, Gateway, and DNS address from the network.

When a receiver is connected to a network using DHCP, an IP address is assigned to the receiver by the network. To verify the IP address of the receiver, select the up button from the keypad when the Home screen is displayed. The Ethernet IP address appears as shown.

Alloy GNSS reference receiver User Guide

If your network installation requires the receiver to be configured with a static IP address, you can configure the Ethernet settings either using the front panel as described in the Chapter 5,

Configuring the Receiver Using the Keypad and Display, via the web server or the WinFlash utility.

The web server can be only used when the receiver is connected to a network and has a valid Ethernet configuration.

Use the WinFlash utility to configure the Ethernet settings of a receiver that is to be connected to a network that requires static IP addresses:

1. Contact the network administrator for the correct settings for the receiver.

2. Use the serial cable provided with the receiver to connect the receiver to a computer

running the WinFlash utility.

3. Turn on the receiver.

4. On the computer, start the WinFlash utility.

5. From the Device Configuration screen:

a. From the Device type list, select Trimble Alloy Receiver.

b. From the PC serial port list, select the appropriate PC serial port.

Alloy GNSS reference receiver User Guide

c. Click Next.

6. From the Operation Selection screen, select Configure Ethernet settings, and then click

Alloy GNSS reference receiver User Guide

7. From the Settings Review screen, click Finish:

Once the WinFlash utility connects to the receiver, the Ethernet Configuration dialog appears.

8. Enter the network settings in the Ethernet Configuration dialog. Click OK:

The Broadcast setting is the IP address that is used to broadcast to all devices on the subnet. This is usually the highest address (usually 255) in the subnet.

Default Settings and Application Files

In this chapter:

 Default receiver settings  Resetting the receiver to factory defaults  Using application files to duplicate

receiver settings

Most of the 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 Alloy. 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.

The Alloy receiver extends the use of application files to allow simplified receiver setting duplication in multiple receivers. This is sometimes referred to as receiver cloning and is very useful when preparing a large group of receivers for a field data collection campaign.

Resetting the receiver to factory defaults

To reset the receiver to its factory defaults, press for 35 seconds.

Using application files to duplicate receiver settings

The Alloy receiver allows the extensive use of application files in order to retain a unique receiver configuration. With the Alloy you can create an application file that includes most of the receiver's unique configuration settings. That application file can then be copied and placed on another Alloy receiver to quickly configure it to match the first receiver.

For settings that are not stored in an application file there are also “clone” files. Clone files allow you to capture all of the settings not included in the application file. Both the clone file and the application file can be loaded onto other Alloy receivers to give them the exact configuration as the first receiver. This is called “receiver configuration cloning” or “cloning”. Receiver cloning greatly reduces the time required to prepare a large group of receivers for field operations.

Alloy GNSS reference receiver User Guide

The Application Files submenu (select Receiver Configuration/Application Files) provides the required tools to use these features. There are two variable fields:

 Filename allows you to enter a unique name for a stored configuration file.  Operation allows you to select a particular operation from a drop-down list:

The available operations are:

Alloy GNSS reference receiver User Guide

NMEA-0183 message overview

When NMEA-0183 output is enabled, a subset of NMEA-0183 messages can be output to external instruments and equipment connected to the receiver serial ports. These NMEA-0183 messages let external devices use selected data collected or computed by the GNSS receiver.

All messages conform to the NMEA-0183 version 3.01 format. All begin with $ and end with a carriage return and a line feed. Data fields follow comma (,) delimiters and are variable in length. Null fields still follow comma (,) delimiters but contain no information.

An asterisk (*) delimiter and checksum value follow the last field of data contained in an NMEA0183 message. The checksum is the 8-bit exclusive of all characters in the message, including the commas between fields, but not including the $ and asterisk delimiters. The hexadecimal result is converted to two ASCII characters (0-9, A-F). The most significant character appears first.

Report max DQI=2 NMEA GGA string – When enabled, the Quality Indicator field in the GGA output message will never be greater than 2 (Differential GPS). Only to be used with legacy systems that do not fully support the NMEA standard.

Report max correction age 9 sec in NMEA GGA string – When enabled, the Age of differential data field in the GGA message will never be greater than 9 sec. Only to be used with legacy systems that do not fully support the NMEA standard.

Report extended information in NMEA GGA and RMC strings - By default this check box is enabled to provide high precision position data in the NMEA messages. You should clear this check box to conform to the NMEA standard message length of 82 characters. However, if you do, the precision of the position and altitude data is reduced by truncating the number of decimal places.
