MPC products address the need for an end-to-end solution. They provide the building blocks at both ends of the asset management system including the on-board units mounted in the vehicle and the software installed at the ﬁxed base station. The on-board components are centered on the CrossCheck GSM, (the GPS receiver with integrated IQ Event Engine and a GSM phone). You can use the CrossCheck GSM as a standalone unit or you can interface it with external accessories and sensors to make it function as part of an on-board system.Optional external units include a Mobile Data Terminal (MDT) to provide a driver interface to exchange messages or generate manual

CrossCheck GSM Operation Manual 1-5 Overview event reports, and a handset for use where voice communication is required.You can use the Trimble FleetVision software package at the base station, as a standalone ﬂeet management system or as the communications platform for an integrated system. FleetVision features include event and alarm reporting, data handling, as well as map displays, allowing you to view the positions of mobile assets in real-time or replayed for analysis purposes. FleetVision includes an External System Interface (ESI) package. This gives system integrators and application developers the ability to customize the system by interfacing to third-party “back ofﬁce systems” such as order/stock processing, route optimization systems, and the like. 1.3 CrossCheck GSM Features The CrossCheck GSM includes these features: • Eight channel GPS receiver • Conﬁgurable, intelligent IQ Event Engine (refer to Chapter 5) • Slim proﬁle for easy installation • One serial port for RS-232 (DCE) serial communications with data throughput of 300, 600, 1200, 2400, 4800, 9600 (default), 19200, or 38400 bps • Extensive discrete I/O (inputs and outputs) for vehicle peripheral support • Optional Voice Upgrade Kit which supports hands-free operation • Password-protected data communications • NMEA-0183 Version 2.1 sentence output (see Appendix D for detailed information) • Support for the Trimble Standard Interface Protocol (TSIP), allowing you to set GPS parameters using the serial port (see Appendix C for detailed information)

CrossCheck GSM Operation Manual 1-7 Overview 1.4 Global Systems for Mobile Communications Cellular mobile telephone systems have been widely available throughout the world. However, because cellular mobile telephone systems are regulated at the national level, these systems are not generally compatible with each other. To resolve this dilemma of being able to communicate from almost anywhere, but only within your own system, The European telecommunications operators (the Conference of European Postal and Telecommunications Administration, or CEPT) designed a new mobile telephone network. This network has evolved into GSM, and CEPT has turned over management of GSM to the European Technical Standards Institute (ETSI). GSM is the predominant mobile communications system throughout Europe and GSM is also widely available throughout the world. 1.4.1 GSM Cellular Phone System The Global Standard for Mobile (GSM) protocol offers a variety of data services that allow users to send and receive data at rates of up to 9600 bps. Data may be delivered over ISDN, Packet Switched or Circuit Switched Data Networks (PSDN or CSDN) and via the Short Message Service (SMS). SMS is a store and forward service for the bi-directional exchange of alphanumeric messages of up to 160 characters. Architecture of the GSM network An Automatic Vehicle Location (AVL) or Asset Management System based on GSM consists of several distinct components. The Crosscheck GSM is the mobile unit that is installed in the vehicle and contains the Subscriber Identity Module (SIM). The SIM card contains a unique International Mobile Subscriber Identity (IMSI) number. This enables the network to identify the user and therefore allow the terminal to have access to speciﬁc, subscriber services. The GSM “cloud” is made up of two sections:

1-8 CrossCheck GSM Operation ManualOverview • The Base Station Subsystem that controls the radio link with the mobiles through local cells • The Network Subsystem that controls the switching of calls between the network users, mobile to mobile, and between mobile and ﬁxed linesThe Network Subsystem stores all administrative information including the current cell being used by the mobile unit which allows call routing and the roaming ability of GSM. An important feature of GSM is this ability to move across international and network borders, a feature that is described as “roaming.” If arrangements have been made with the service provider, the SIM card will be enabled for roaming. • Mobile Station (MS) • CrossCheck GSM includes a radio transmitter, receiver and voice encoder, decoder. The optional Voice Upgrade Kit includes a handset. • Subscriber Identify Module (SIM)—an electronic card containing a computer chip. The chip contains the subscriber information and operating system parameters. SIMs provide authentication, encryption, information storage, and subscriber account protection services (including Personal Identiﬁcation Number or PIN, and Pin Unblocking Key or PUK). GSM users can move the SIM from one CrossCheck GSM to another.•Other network components•Voicemail System (VMS)— delivers messages and pages to GSM users.•Short Message Service Center (SMSC)—delivers text messages (up to 160 characters) to GSM users. •Executable Short Message Platform—delivers commands to the SIM card via an over-the-air interface.

CrossCheck GSM Operation Manual 1-11 Overview1.5 The Global Positioning SystemThe Global Positioning System is a satellite-based navigation system operated and maintained by the U.S. Department of Defense. GPS consists of a constellation of 24 satellites providing world-wide, 24 hour, three dimensional (3D) coverage. Although originally conceived for military needs, GPS has a broad array of civilian applications including timing, surveying, ﬂeet management, marine, land, aviation, and vehicle navigation.GPS is the most accurate technology available for navigation. As a satellite based system, GPS is immune from the limitations of land based systems, which have limited coverage and whose accuracy varies with geographic location and, even under ideal conditions, cannot compare with GPS.By computing the distance to GPS satellites orbiting the earth, a GPS receiver can calculate an accurate position. This process is called satellite ranging. GPS receivers can also provide precise time, speed, and course measurements which are important for vehicle mobile positioning and communications applications. 1.6 GPS ReceiverThe CrossCheck GSM includes an advanced GPS receiver, which provides the position, course, speed and time information required for AVL and ﬂeet management applications. A brief overview of the GPS receiver’s architecture and operation is provided below. The CrossCheck GSM’s GPS receiver features an eight-channel digital signal processor (DSP) which operates at the GPS L1 frequency (1575.42 MHz) and processes the AcquisitionCoarse/Acquisition (C/A) code portion of the GPS signal. The RF and digital signal processing components of the GPS module are custom ASICs designed by Trimble.

1-12 CrossCheck GSM Operation ManualOverview1.7 GSM OperationAt power up the CrossCheck GSM automatically searches for a GSM network using a set of tables on the SIM card to determine which GSM network the phone should try to reach. These tables are the Public Land Mobile Network (PLMN) tables and each GSM network has its own unique PLMN number. This number is the Mobile Country Code (MCC) and the Mobile Network Code (MNC), which are also the ﬁrst numbers of the subscriber’s IMSI. (The IMSI is the MCC, plus the MNC, plus the MSIN.) The PLMN table ﬁnds either the subscriber’s home network or a network that will allow service, and registers to the network consistent with the handset. The responding network’s MSC passes this request for service to the VLR. If the VLR has information about this IMSI, then it passes the request to the AUC for authentication. If the VLR cannot ﬁnd any information on this IMSI, it must pass the request to the HLR and get approval before passing on the request.Once the VLR has approval to grant the request for service, it knows the user identity, what features are authorized, and the authentication codes (from the AUC). The VLR then passes the request back to the MSC for routing to the number being called.If the number being called is a land-based number, the MSC passes the call to the Public Switched Telephone Network (PSTN) for connection. If the number being called is another mobile number, the MSC repeats the process described above to locate the number being dialed. Depending on services supported, the call will be answered, be routed to voicemail, be intercepted by a live answering service, or simply time out with the message that the number being dialed is not available. In any case, the transmission is digital and encrypted so information cannot be intercepted easily.

CrossCheck GSM Operation Manual 2-12 InstallationInstructions for installing the CrossCheck GSM mobile unit in the vehicle are introduced in this chapter. This chapter covers:•Unpacking the CrossCheck GSM•Installer supplied parts•Mounting the CrossCheck GSM•Mounting the GPS and GSM cellular antennas, and routing the antenna cables•Connecting laptop computers, Windows CE devices, and other ASCII peripherals to the MDT/Aux port•Connecting discrete input and output leads•Connecting power•Mounting and connecting the Cellular Handset, hands-free cradle, and remote microphone•Inserting the SIMThe CrossCheck GSM can be installed before or after conﬁguring its IQEvent Engine. For example, you might want to conﬁgure all of the CrossCheck GSM units for a ﬂeet of vehicles on a bench prior to installation. If you prefer to conﬁgure the CrossCheck GSM first, read Chapter 3, Conﬁguration, before installing the CrossCheck GSM.

2-2 CrossCheck GSM Operation ManualInstallationNote – If you plan to install the CrossCheck GSM before conﬁguring the unit, be sure to leave adequate clearance to the MDT/Aux port and other connectors. Adequate clearance must exist to connect a laptop or Mobile Data Device to the unit, and you must be able to read the LED indicators if troubleshooting is required. 2.1 CrossCheck GSM ConnectionsThis sections shows the CrossCheck GSM components connections.

For a complete listing of CrossCheck GSM unit and component part numbers, see CrossCheck GSM Part Numbers on page A-12.2.3 Installer Supplied PartsThe following parts must be supplied by the installer:•Mounting fasteners for the CrossCheck GSM.•Fasteners for mounting the GPS antenna if the antenna is the bulkhead type.•Cable ties for securing cables to the vehicle.•Any special connectors and adapters required to connect interface devices and power leads—the power and I/O cable is supplied with the CrossCheck GSM PN 43455-01 only.•Subscriber Identity Module (SIM) cards.•GSM antenna.•GPS antenna (supplied with the CrossCheck GSM (PN 43455-01 only).2.4 Mounting the CrossCheck GSMThe CrossCheck GSM can be installed inside any type of vehicle and in any orientation. It can be installed in an enclosed compartment or in a location with limited accessibility as long as the environmental speciﬁcations are maintained to ensure reliable operation. For example, the CrossCheck GSM can be installed on the ﬂoor under a seat or on a wall behind a seat. (The CrossCheck GSM cannot be installed inside the engine compartment, wheel well, chassis, or on any exterior surface of the vehicle.)Choose a location for the CrossCheck GSM which allows for convenient routing and connection of the antenna and interface cables,

CrossCheck GSM Operation Manual 2-7 Installationand which has access to a power source. When selecting a mounting location, consider the speciﬁcations listed in Appendix A, Table A-8, and avoid the following hazards:•Direct exposure to weather•Excessive heat (for example, exhaust manifolds)•Excessive cold (for example, refrigeration units)•High vibration areas (engine compartment, transmission)•Corrosive ﬂuids and gases (acids, petroleum products)•Direct exposure to water (the CrossCheck GSM is not waterproof)To mount the CrossCheck GSM:1. Choose the mounting location.The CrossCheck GSM can be mounted horizontally, vertically, or in any convenient orientation protected from moisture. During normal system operation, the user does not need to see the CrossCheck GSM LED indicators. However, the ability to see the LED indicators is a deﬁnite advantage when troubleshooting the unit. The integral mounting ﬂange is designed to secure the CrossCheck GSM to a ﬂat surface. The ﬂange has four holes for securing the unit with fasteners. 2. Use self tapping screws or machine screws to secure the unit to the mounting surface. Figure 2-4 shows the mounting dimensions.

2-8 CrossCheck GSM Operation ManualInstallationFigure 2-4 CrossCheck GSM Mounting Dimensions (in millimeters)The installer must provide an appropriate selection of fasteners to secure the CrossCheck GSM to the mounting surface. a. When using self-tapping screws, select an appropriate size and length for the mounting surface. The hole size leaves some allowance for holes drilled slightly off center from the speciﬁed dimensions. b. When using machine screws, select a screw length which extends a safe distance beyond the mounting surface, and secure the screw with a washer and nut. Lock washers are recommended to prevent vehicle vibration from loosening the fasteners.In general, Trimble Navigation recommends the use of number m3.5 (or number 6) pan head machine screws.69.9205.54.8

CrossCheck GSM Operation Manual 2-9 InstallationCaution – Use washers sized small enough that they do not tighten down on the plastic cover of the CrossCheck GSM when the mounting screws are secured. Otherwise, over stressing the plastic mounting surface when tightening the mounting screws can cause the plastic to crack. Tightening screws without using washers can lead to compressing, cracking, or deforming the mounting surface. 2.4.1 Connecting CrossCheck GSM to the Vehicle ChassisFor proper operation, the aluminum chassis of the CrossCheck GSM must be connected electrically (grounded) to the chassis of the vehicle on which it installed. This can be accomplished by:•Direct connection through metal screws (preferred), or •Using the chassis ground wireDirect Connection through Mounting ScrewsMount the CrossCheck GSM mobile unit on a metal surface that is permanently attached to the vehicle chassis (for example the base of the trunk, or a mounting plate that is permanently attached to the chassis using metal screws). Fasten down the CrossCheck GSM mobile unit using metal screws driven through the metal tabs on the sides of the unit. Make sure the screws are tight, and that they make contact both with the metal on the CrossCheck GSM and with the vehicle chassis. Use star washers to ensure a reliable electrical contact to the metal tabs.Note – If this direct connection through mounting screws method is used for chassis connection, then the chassis ground (pin 3 on the power and discrete I/O connector) on CrossCheck GSM should be left unconnected.

2-10 CrossCheck GSM Operation ManualInstallationConnection through the Chassis Ground WireIf the CrossCheck GSM unit cannot be mounted directly on a metal surface that is attached to the vehicle, then use the chassis ground wire (pin 3 on the power and discrete I/O connector) to make electrical contact to the vehicle chassis. Use a wire with gauge of at least 18 AWG to connect the CrossCheck GSM power connector to the vehicle chassis. Keep the wire length as short as possible by selecting a connection point in the vehicle chassis that is close to the CrossCheck GSM unit. Use a metal screw with a star washer to ensure a reliable electrical contact to the vehicle chassis. 2.5 Choosing the GPS Antenna Mounting LocationAntenna location is critical for optimum GPS performance. Choose a location for the GPS antenna with an unobstructed view of the sky, and which is safe from damage during normal vehicle operation and maintenance. GPS satellite signals do not penetrate metal or dense wood. GPS signals can penetrate plastic, glass and tinted glass (except metalized glass), ﬁberglass and plexiglass materials as long as the surface is relatively dry. Caution – Never mount the GPS antenna under a metalized glass windshield, such as those used in some vehicles for window de-fogging or de-icing systems. The GPS antenna can be mounted under a tinted-glass windshield.When selecting a location for the GPS antenna, ensure that the antenna is not shielded from satellite signals by metal objects or other impenetrable materials. For optimal GPS performance, the antenna location should have a clear view of the sky.

CrossCheck GSM Operation Manual 2-11 InstallationDisclaimer — The instructions included in this section apply to the GPS antennas sold by Trimble and may not apply to third-party products. There are many other GPS antennas available on the market which may or may not be compatible with the CrossCheck GSM, including combined GPS/GSM cellular antenna solutions which have not yet been tested and certified by Trimble. Mount the antenna in a horizontal position (see Figure 2-5 on page 2-12), facing the sky. If the antenna must be located in the vicinity of other antennas (radio, cellular phone), locate the GPS antenna at least 46 centimeters (approximately 18 inches) away. Avoid areas of high vibration (for example, engine hoods). For permanent installations, choose a location with access both above and below the antenna mounting surface. This access is required for installing fasteners and for routing the antenna cable.Note – The standard length of magnetic mount and bulkhead-mount GPS antenna cables supplied by Trimble is 5 meters (or approximately 16 ft.). Longer bulkhead-mount antenna cables can be prepared by the installer using the guidelines presented in Appendix A, Speciﬁcations. Since GPS satellite signals can penetrate plastic, ﬁberglass and glass, the GPS antenna can also be installed on a dashboard under a sloped windshield (if the windshield is not metallized) or under a plastic fender or bumper. These alternative locations are likely to offer less satellite coverage, since the metal components of the vehicle shield the antenna from portions of the sky.

Figure 2-11 Miniature Magnetic GPS AntennaTo mount the Magnetic GPS Antenna:1. Choose the antenna mounting location (see Choosing the GPS Antenna Mounting Location on page 2-10). 2. Mount the antenna to a ferrous surface. The antenna can be mounted on the exterior of the vehicle or in the vehicle’s interior. 3. Route the antenna cable. The antenna features a permanent antenna cable which must be routed to the location where the CrossCheck GSM is mounted. For detailed cable routing guidelines, see Routing the GPS Antenna Cable on page 2-20.Caution – The magnetic-mount antenna cable is exposed to the environment. Since wind could cause the cable to whip around, use tie wraps to secure the cable along its route.

2-20 CrossCheck GSM Operation ManualInstallationCaution – The magnetic-mount antenna cable has no strain relief at the antenna end of the cable and is not recommended for permanent installations.2.6 Routing the GPS Antenna CableThe Magnetic GPS Antenna has an integral antenna cable, and the Miniature Bulkhead GPS Antennas have a separate 5 meter (or approximately 16 ft.) cable. If you are using one of the Miniature Bulkhead GPS Antenna units, attach the antenna cable to the SMA connector on the base of the antenna prior to routing the cable. When routing the cable, start at the antenna and choose the most direct path to the CrossCheck GSM while avoiding the following hazards:•Make sure that at least two inches of clearance exists between the CrossCheck GSM’s Antenna connector and the nearest obstacle.•Make all cable bends, especially the bend at the SMA strain relief to the Antenna connector, with at least one-half inch bend radius. •Provide an adequate service loop when routing the cable around vehicle hinges to ensure that the cable is not inadvertently pinched when a hinged door opens or closes.•Make sure that the coax cable is not routed through areas where vehicle movement can abrade the cable surface. •Never coil the excess antenna cable, particularly the Magnetic GPS antenna cable. A coiled cable can act as an antenna and may receive interference.•Protect cables from exposure to corrosive ﬂuids.Once the cable is routed and secured, attach the cable to the CrossCheck GSM GPS (SMA) connector.

CrossCheck GSM Operation Manual 2-21 Installation2.7 Choosing a GSM Antenna Mounting LocationAlthough not as critical as GPS antenna placement, cellular antenna placement is also important. Mount the cellular whip antenna in a vertical orientation in a location where it is safe from damage during normal vehicle operation and maintenance. Automated vehicle washes may damage misplaced cellular antennas. If you are installing multiple antennas, maintain a separation of at least 46 centimeters (or approximately 18 in.) between the cellular (or other) and GPS antennas (see Figure 2-12). If you are using a combination GPS/cellular antenna, maintain a separation of at least 46 centimeters (or approximately 18 in.) between the combination antenna and any other antennas.

2-26 CrossCheck GSM Operation ManualInstallation2.8.1 Inputs (IP0 to IP3)The CrossCheck GSM unit supports four discrete inputs. The circuit diagram is shown in Figure 2-14.Figure 2-14 Input Circuit DiagramEach input ﬂoats to a logic high state (inactive) when left open. Grounding an input causes a logic low state (active). The CrossCheck GSM can be conﬁgured to detect either logic high or logic low states at the inputs whenever the unit is powered on. Input Logic High: Open circuit or Vin > 2.4 VDCInput Logic Low: Vin < 0.6 VDCThe inputs must remain in either state for at least 200 milliseconds before the CrossCheck GSM detects the input.Input Current (Max) Iin < 3 milliamps 1 milliamp is typical at 12V.Input Protection: Protected up to at least VBatt continuous 3K330K1.0µFTo logic470pfInput 100K3.3V/10m/A

CrossCheck GSM Operation Manual 2-27 InstallationNote – The CrossCheck GSM can be conﬁgured to detect only a logic low (grounded) input when it is powered off and in power management mode. The discrete inputs are compatible with properly connected relays and switches or with standard 3.3 volt logic levels. A properly connected relay or switch allows the input to ﬂoat high in one position and grounds the input in the other position. The input must be held in a particular logic state for at least 200 msec (conﬁgurable up to 1 second) so the CrossCheck GSM can detect it.2.8.2 Outputs (XP0 to XP2)The CrossCheck GSM features three discrete outputs (XP0-XP2) for driving external devices such as relays. When inactive (default state), the discrete outputs are tied to vehicle battery voltage (nominally 12 VDC) through a 15 kOhm resistor. When active, the outputs are shorted to ground through a bipolar junction transistor. In the active (low) state, the outputs can sink up to 200 milliamps. Figure 2-15 shows a diagram of a discrete output.

(For more information on TAIP commands, refer to the TAIP/IQEvent Engine Reference Manual.) The MDT port supports the following modes:•Normal—Supports any combination of TAIP, TSIP, and NMEA protocols•PAD—All input is converted into TAIP TX messages, all output is text stripped from TX messages•AT—Trafﬁc consists of AT commands and data from the MDT device to GSM, and GSM responses to the MDT device from the CrossCheck GSMThe MDT inputs (Rx) accept –3 to –15 VDC. A low input signal is less than -3VDC (typical). A high input signal is greater than+3VDC. The MDT outputs (Tx) range from –5 volts to –8 volts, depending on the load. Note – During normal operation, the MDT/Aux service port communicates with a PC or Mobile Data Device using TAIP messages (see Chapter 5, IQEvent Engine Overview and the IQEvent Engine/TAIP Reference Manual for detailed information) at 9600 bps, 8-N-1, and no ﬂow control. The baud rate and other communications parameters can be set to match the PC or Mobile Data Device settings.Figure 2-16 shows the cable connections between a PC and the CrossCheck GSM.

CrossCheck GSM Operation Manual 2-31 Installation2.10 CrossCheck GSM Power The CrossCheck GSM operates on input voltages from 9-32 VDC. The low noise ampliﬁer integrated on the GPS antenna draws power from the CrossCheck GSM through the antenna cable. The CrossCheck GSM does not require any special power up or down sequencing. The CrossCheck GSM’s power circuitry is designed to protect the unit from random power ﬂuctuations and conditions. Input circuits protect against transient voltage spikes found in most auto and truck environments. An external fuse protects against excessive current.See Appendix A, Speciﬁcations, for more information on the CrossCheck GSM power requirements.

CrossCheck GSM Operation Manual 2-33 InstallationThe CrossCheck GSM is protected against both input power over-voltage and reverse polarity. The primary power cable has a built-in 2-amp fuse. The DC ground line connects to the vehicle’s DC ground. The Ignition Sense lead, if connected to a source of ignition switched battery voltage, senses when the vehicle’s ignition is active. There are three connection options for connecting the Power, Ground, and Ignition Sense wires. These options are described in the next three sections.Note – The CrossCheck GSM (including the cellular phone) will power down automatically when input voltage drops below 9V or exceeds 32V, see the input power speciﬁcation in Appendix A. IQEvent Engine signals for under- and over-voltage are available, with default values of 9.5V and 31.5V respectively.For conﬁgurations, refer to the TAIP PM message description in the TAIP/IQEvent Engine Reference Manual.

$2-34 CrossCheck GSM Operation ManualInstallation2.10.1 Connections For Power Management For the Power Management conﬁguration, the CrossCheck GSM operates and draws power (150 milliamps nominal) continuously only when the vehicle is running. When the ignition is off, the CrossCheck GSM responds to the change in the state of the Ignition Sense lead and goes to sleep (at programmed intervals), drawing reduced power (<10 milliamps). When IQEvent Engine is conﬁgured for power management, the CrossCheck GSM can be scheduled to wake up periodically, typically long enough to refresh its GPS position) or could wake up when triggered by an external signal or GSM Ring, and then go back to standby mode. Therefore, even though the CrossCheck GSM is drawing power while awake, its duty cycle is a fraction of what it would be under continuous power, and battery life is extended. For additional information, refer to PM Message in the TAIP/IQEvent Engine Reference Manual.$

CrossCheck GSM Operation Manual 3-5 Conﬁguration3.4 Initializing the CrossCheck GSM Unit This section discusses how you conﬁgure your Subscriber Identity Module (SIM), program your GSM PIN and calling options, and set the TAIP ID.3.4.1 SIM Conﬁguration and ActivationTo operate CrossCheck GSM, you need a SIM card. A SIM is a “smart” card containing a microprocessor and associated logic. It is about the size of a postage stamp. SIMs can be obtained from a network provider, a service provider, or from a mobile phone shop. When you obtain a SIM, make sure that it is conﬁgured for data and voice operation, as well as SMS services that normally come with GSM cellular service.You need a data number if the circuit switched connection is to be made from a land line connection (PSTN/ISDN). However, a voice number is sufﬁcient if the circuit switched connection is between two GSM units (CrossCheck and GSM phone at the base). In this case, the voice number supports voice, SMS, and circuit switched modes.You can use SMS for simple reporting, either querying from the base or exception reporting from the mobile unit. It should not be used for lengthy sessions, such as log download.The SIM card is the true identity of any GSM phone (including a CrossCheck GSM) as far as the mobile network is concerned. Once you have obtained a SIM card, the network you have chosen may require that you set a PIN (Personal Identiﬁcation Number), which is a four to eight digit number that can be used to protect the SIM from unauthorized use. You can set the PIN on the SIM by putting the SIM into a standard mobile phone and using that phone's PIN setting ability. You will also need to supply the PIN to the CrossCheck GSM unit as it will be initializing the SIM on your behalf. Trimble recommends setting the PIN in the CrossCheck GSM unit before inserting the SIM, as this avoids having old PINs rejected by the SIM (see below). The

3-6 CrossCheck GSM Operation ManualConﬁgurationPIN is set using the PC message (>SPCGE;PIN=x...x<) as described in Programming the GSM PIN and Calling Options on page 3-8. Having set the PIN, Trimble recommends that you:1. Verify that the PIN is correct, (>QPC<). 2. Remove power from the CrossCheck.3. Insert the SIM.4. Apply power to the unit.The supplier of your SIM will probably provide additional information. If you intend to send SMS (Short Message Service) messages, make sure you are provided with an SCA (Service Center Address). This is the telephone number of an SMSC (Short Message Service Center) and is required by the CrossCheck GSM in order for it to send SMS messages. (Set it using the >SPCGE;SCA=nnnnn...< command where nnnnn is the SCA). Typically, each network provider has one or more SMSCs. Please be aware that there are some reports of SMS interoperability issues between some networks or subnetworks, but these are few and there should not be a problem if you are operating within a single network.Warning – Incorrect entry of the PIN could cause the SIM to be blocked. For more information on blocked SIMs, see SIMs and the Network.3.4.2 SIMs and the NetworkThe SIM controls network access by verifying that the PIN it contains matches the PIN supplied by the CrossCheck GSM ﬁrmware. If the numbers do not match, or if the SIM is not inserted in the CrossCheck GSM, the amber GSM LED fast blinks and one of the following messages is output to the MDT port:>SPCGE;SIM=PIN ERR< - PIN in PC message does not match SIM>SPCGE;SIM=BLANKPIN< - PIN field in PC message is empty

CrossCheck GSM Operation Manual 3-7 Conﬁguration>SPCGE;SIM=ABSENT< - SIM card is not presentAccess to the GSM network is then prevented. Once a PIN mismatch occurs, the CrossCheck GSM ﬁrmware will not attempt to initialize the SIM with its PIN (even after a power cycle) until another set pin command (>SPC...<) has been entered. This is done to prevent the SIM being “blocked” (see below). After a PIN mismatch, subsequent CrossCheck GSM resets causes the GSM LED to fast blink, and the following message is displayed at the MDT port:>SPCGE;SIM=PIN ERR<Once a new set PIN command has been entered, the CrossCheck GSM ﬁrmware attempts once more to initialize the SIM with the PIN. This occurs even if an identical PIN is entered in the set PIN command to allow for the condition where the PIN is correct but an incorrect SIM was inserted.Warning – After three consecutive PIN errors, the SIM will be “blocked.” If this is the case, the Comms LED on the CrossCheck GSM fast blinks, and the following message is output to the MDT port: >SPCGE;SIM=PUK REQ< You will now have to supply a PUK (Personal Unlocking Key). You will need to obtain this eight digit number from the network operator. To enter this number, you will need to place the SIM in a standard mobile phone and use its PUK capabilities. After ten consecutive wrong entries of a PUK, the SIM will be permanently blocked from GSM operation. A permanently blocked SIM will cause the CrossCheck GSM unit amber LED to fast blink, and the following message is displayed at the MDT port:>SPCGE;SIM=FAILED<You can check the status of the SIM at anytime by using the query:>QPC;SIM=<

3-8 CrossCheck GSM Operation ManualConﬁguration3.4.3 Further InformationThere are a variety of sources of further information (for example, the use of PIN2, number lockouts, and PC utilities for conﬁguring SIMs), particularly on the web. Trimble recommends that you do a web search for this information as it is continuously changing. ETSI is a good source of deﬁnitive material (http://www.etsi.org at the time of writing), as is the GSM association (http://www.gsmworld.com at the time of writing).3.4.4 Programming the GSM PIN and Calling OptionsEnter the cellular PIN using the TAIP PC message:>SPCGE;PIN=x...x<where x...x is the PIN currently deﬁned for the SIM that is inserted in the CrossCheck GSM’s SIM slot. If no PIN is deﬁned for the SIM card, you do not need to enter a PIN. Once a PIN is entered, it is maintained in non-volatile (battery-backed) memory, and is used on each CrossCheck GSM power up to initialize the GSM module. Whenever the SIM card is changed, the PIN must be re-entered.Note – Due to factory default settings, messages received from the CrossCheck GSM always include the unit’s Vehicle ID and an appended checksum. For brevity, these two parameter settings are ignored in the examples below. Factory DefaultsTo query the CrossCheck GSM for the current conﬁguration, send the following message:>QPC<A new CrossCheck GSM (out of the carton) responds with a message containing the factory default parameter settings for the protocol conﬁguration:

For Circuit Switched calls, the BRN and BRA parameters allow adjustment of the CrossCheck GSM’s built-in scheme for retry attempts when a circuit-switched (CSW) call to the base station cannot be connected. The BRN parameters adjust the retry scheme for Normal connections (when no alarm messages are queued), and the BRA parameters adjust the retry scheme for Alarm connections (when at least one alarm message is queued). Note – When CrossCheck GSM is in Circuit Switched Data mode, it can support either PSTN or ISDN connections. Contact your network operator for information on which connection is supported.Parameters consist of a back-off time (in seconds) and a maximum number of retries. The back-off time speciﬁes only the time until the ﬁrst retry attempt; subsequent retry times are determined by the back-off / retry algorithm. For detailed information, refer to Back-off/Retry Algorithm in the TAIP/IIQEvent Engine Reference Manual. Note – For detailed information about message queue operation, see Destination Addresses and Message Queuing in the TAIP/IQEvent Engine Reference Manual.For CSW calls, ALH is one of three Alarm mode parameter settings. These modes determine how Alarm messages are processed when an active CSW call is in progress. For detailed information about selecting an Alarm mode (ALH), see Alarm Handling in the TAIP/IQEvent Engine Reference Manual. For detailed information about each message parameter, refer to PC Message in the TAIP/IQEvent Engine Reference Manual.

Each CrossCheck GSM should be assigned a unique alphanumeric ID to give the vehicle a unique identity. To set the ID to CA20, enter the following message:>SIDCA20<The CrossCheck GSM should reply with the following response:>RIDCA20<Note – The CrossCheck GSM will accept a TAIP ID of between four and eight digits. However, FleetVision will accept only four digits. If you are using FleetVision, the TAIP ID must be four digits.

CrossCheck GSM Operation Manual 3-11 Conﬁguration3.4.6 Circuit-Switched versus Short Message Service ModeCircuit-Switched (CSW) calls rely on connection-oriented communications for sending data between parties. A typical CSW call occurs in a data transfer between two computers. The calling computer sends its call request through a modem, which sets up the call to the modem connected to the receiving computer. Once the connection is established, the data is transferred between the modems.Short Message Service calls do not require a connection to the party being called. Instead of setting up a connection between two parties, SMS messages go to a SMS center (SMSC). This central processing facility then buffers the message until the recipient phone becomes active.While CSW data is a modulated and demodulated signal, SMS is a alphanumeric message containing up to 160 characters - much like a pager message. CSW mode is efﬁcient for large volumes of data, while SMS is best for short messages.CrossCheck GSM can be conﬁgured to use SMS to provide cost-effective data transfer capabilities.

3-12 CrossCheck GSM Operation ManualConﬁguration3.5 Testing the Handset InstallationThe CrossCheck GSM should be tested in both handset and hands-free voice mode before ﬁnishing the installation. For detailed instructions, see Programming the GSM PIN and Calling Options on page 3-8.3.5.1 Service Provider ConﬁgurationYou need to select a GSM service provider, purchase a SIM, and have the service provider initialize your SIM. The SIM should be initialized for voice (Circuit Switched Communications), and for SMS (Data Services) if desired.3.5.2 Voice Mode TestTo test the Voice mode:1. Place a call to a test number.2. Test the handset and hands-free modes to assure proper operation during the call.3. End the call and have someone call your cellular phone number.4. End the call.

CrossCheck GSM Operation Manual 4-14 OperationOnce the installation and conﬁguration are completed, the CrossCheck GSM is ready for operation. When power is applied, the CrossCheck GSM can then operate automatically without user intervention, based on its IQEvent Engine conﬁguration.This chapter provides a basic overview of the CrossCheck GSM’s operation, including:•LED Indicators•GPS Receiver•GSM PhoneThe IQEvent Engine controls the CrossCheck GSM’s operation and interfaces with both the GPS receiver and GSM phone. For detailed information, see the TAIP/IQEvent Engine Reference Manual.

4-2 CrossCheck GSM Operation ManualOperation4.1 LED IndicatorsThe CrossCheck GSM includes two LED indicators: GPS and GSM. The IQEvent Engine continuously monitors GPS receiver and GSM phone operation and controls the two LED indicators (see Figure 4-1). Figure 4-1 Crosscheck GSM LED Indicators 4.1.1 LED StatesThe GPS and GSM LED each have three states: On, Off, and Blink. The CrossCheck GSM’s power is off when both LED indicators are off, and power is on when one or more LED indicators are on or blinking.GPS LED (Green)GSM LED (Amber)

4-4 CrossCheck GSM Operation ManualOperation4.1.3 LED Power-on SequenceWhen the CrossCheck GSM’s ignition input and power inputs are activated, both LEDs blink once, turn off for approximately ﬁve seconds, then are on for approximately two seconds.The GPS LED is on for approximately two seconds, then blinks until the ﬁrst position ﬁx is computed. During this period, the GSM LED blinks until the unit is established in a GSM area, at which point, the GSM LED turns off. When a call is active, the GSM LED stays on for the duration of the call. When the ﬁrst position ﬁx is computed, the GPS LED turns on continuously. Afterwards, the GPS LED remains on when computing position ﬁxes or blinks when no position ﬁxes are computed. The GSM LED turns on when a GSM connection is in progress, turns off when no call is in progress, and blinks if no GSM coverage is available or call has not been established.4.2 GPS Receiver OperationAt power-up, the GPS receiver is initialized with the last known position. Using this information, the GPS receiver acquires satellite signals. During the satellite acquisition process, which normally requires less than two minutes, the green GPS LED blinks. Once three or more satellites are acquired, the GPS receiver computes positions, course, speed and time ﬁxes, and the GPS LED remains on. A blinking GPS LED indicates that the GPS receiver is not tracking enough satellites to calculate a current position. This occurs occasionally when the vehicle is obscured from satellite signals by terrain, buildings, trees, tunnels or other structures. During this period, called satellite reacquisition, the GPS receiver continuously searches for the obscured satellites and expands its search to other satellites to continue position computations. For brief blockages, the GPS receiver normally reacquires a lost satellite signal and resumes position ﬁxes in less than two seconds.

CrossCheck GSM Operation Manual 4-5 Operation4.3 GSM OperationWhen the GSM LED (amber LED) is off, it means that the unit is registered with the network or in Standby mode. If the CrossCheck GSM is not registered with the network, the LED will blink, and when a data or voice call is in progress, the LED stays on.The LED indicators are also a useful diagnostic tool. See LED Diagnostic Errors, page 6-9 for more information.

CrossCheck GSM Operation Manual 5-15IQEvent Engine OverviewTheIQEvent Engine (IQEE) manages the operation of the CrossCheck GSM and allows intelligent, autonomous reporting to a base station, to an internal log for later retrieval, or to the MDT/Aux port. By selectively transmitting its position and status only when user-deﬁned events occur the CrossCheck GSM can provide much more speciﬁc data for ﬂeet and mobile asset management, while signiﬁcantly reducing communications costs.TheIQEvent Engine is highly conﬁgurable and can be tailored to a wide variety of AVL applications. Its event-based reporting engine can trigger events and event actions based on user-conﬁgurable speciﬁcations. Thus CrossCheck GSM operation can be automatically changed to react to real-time conditions in the vehicle.TheIQEvent Engine utilizes the following elements to manage CrossCheck GSM operation.•Event Engine—monitor conﬁgured event triggers, generate events, initiate event actions •Wireless Communications—queue messages to selected destinations, establish communications, and handle retries when wireless communications are busy or unavailable•Data Log—store and retrieve event, status, and conﬁguration data in internal Data Log•MDT Interface—Integrate a mobile data terminal or other data device to pass data to/from custom software at the base station

5-2 CrossCheck GSM Operation ManualIQEvent Engine Overview•Discrete I/O—monitor external device inputs as event triggers and allow control of external devices based on IQEE events•Power Management—provide conﬁgurable power-saving strategies•Password Protection—allow secure access to CrossCheck GSM conﬁguration and status dataThe following paragraphs contain a brief description of these elements and the associated TAIP message(s) used for conﬁguration and status. For a detailed description of IQEvent Engine and the TAIP protocol (IQEE’s native protocol), please refer to the TAIP/IQEvent Engine Reference Manual. 5.1 Event EngineThe Event Engine is a simple yet powerful tool to intelligently react to real-time conditions in the vehicle and control CrossCheck GSM reporting and internal operation. It monitors a set of trigger signals, evaluates user-conﬁgured events, generates event reports, and initiates other user-speciﬁed event actions. Its power comes from its conﬁgurability (event triggers and actions are completely user-speciﬁed) and its self-modifying capability (event actions can enable or modify the current conﬁguration).5.1.1 Event TriggersAn event deﬁnition contains a set of conditions or triggers that cause an event to occur. The elemental triggers are listed below, but events are typically triggered by a Boolean combination of triggers. For example, an event could be deﬁned to occur when the vehicle enters or leaves a speciﬁed region while cellular coverage is available and a discrete input is active. The following elemental triggers are available:•Position inside/outside a region•Time elapsed and/or distance traveled

CrossCheck GSM Operation Manual 5-3 IQEvent Engine Overview•Time of day, date•Speed•Heading•Ignition on/off (depending on power wiring)•Discrete Input/Output signals active/inactive•Counter reaches a speciﬁed number•Data received on MDT port•Data log over/under 80% full•GPS status (position ﬁx, antenna connected)•Communications status (available, roaming, open data connection)•Power management status (active, about to sleep, reason for wakeup)•User Flags true/false•Battery voltage low/high/OK5.1.2 Event Reports and Event ActionsAn event deﬁnition speciﬁes an event report and/or other action to occur when the event is triggered. Event reports can be routed to a base station via wireless communications, to the CrossCheck GSM’s MDT serial interface, or to the Data Log. In addition to event reports, other event actions can be speciﬁed. These actions can modify the behavior of the CrossCheck GSM and also modify the conﬁguration of events and event triggers. For example, an event that occurs at 8 AM each day can set the Power Management conﬁguration for a 15 minute cycle, and a complementary event that occurs at 5 PM each day can set the Power Management conﬁguration for a 2 hour cycle, thus adjusting CrossCheck GSM power consumption according to expected use. Another example can accumulate the length of time a vehicle spends

5-4 CrossCheck GSM Operation ManualIQEvent Engine Overviewin a particular area. An event that occurs when entering a region can start/resume a timer, and a complementary event that occurs when exiting a region can stop/suspend the timer.The following are examples of typical event actions:•Report event with position & time to base, MDT, or Data Log•Turn an output device on/off•Start/stop/suspend/resume a timer•Start a distancer•Start/increment a counter•Set a user ﬂag to true or false•Alter an event deﬁnition•Alter a trigger conﬁguration•Alter power management conﬁgurationEvents are conﬁgured via the TAIP ED message.5.2 Wireless CommunicationsThe CrossCheck GSM’s wireless communications channel is used to exchange data with one or more base station locations. It can be used in polled mode, where query/response sequences are initiated by a base station, and in autonomous mode, where IQEE-generated event reports are delivered to up to 10 destinations. The CrossCheck GSM allows conﬁguration for Circuit-Switched or packet-switched (SMS) communications. In polled mode, responses to queries are returned to the caller via open circuit-switched connection, or via SMS message to the originator of the SMS query.In autonomous mode, up to 10 destinations can be conﬁgured, each with an associated Destination Address (phone number) and out-bound message queue. The message queues draw from a single

CrossCheck GSM Operation Manual 5-5 IQEvent Engine Overviewmemory pool, so an accumulation of messages in one DA queue reduces the number of messages available for other DA queues.When an IQEE event is generated, the event report is placed in the DA queue conﬁgured for that event. The conﬁgured event priority determines the priority of the DA queue, and the DA queue priority determines whether an immediate call is made to deliver the messages in the queue. The conﬁgurable priority levels are•Alarm—A DA queue is marked as an Alarm queue when at least one Alarm message is contained in the queue. When a DA queue becomes an Alarm queue, a call is initiated to deliver the messages in the queue. Alarm queues take precedence over Normal queues. Additionally, an Alarm Handling Mode can be conﬁgured to re-route an alarm message to an open connection or to preempt an in-bound connection.•Normal—A DA queue is marked as a Normal queue when at least one Normal message and no Alarm message is contained in the queue. When a DA queue becomes a Normal queue, a call is initiated to deliver the messages in the queue.•Low—A DA queue is marked as a Low priority queue when only Low priority messages are contained in the queue. A Low priority queue accumulates messages without initiating a call.The CrossCheck GSM provides built-in schemes for retry attempts when a circuit-switched call to a Destination Address cannot be connected. Separate retry schemes are provided for Normal connections (when no alarm messages are queued) and for Alarm connections (when at least one alarm message is queued). Conﬁguration parameters allow adjustment of back-off times and maximum number of retries. When the retry limit is reached, no more attempts are made until a new message enters the queue or until the CrossCheck GSM unit is reset (power cycle or Power Management shutdown/wakeup).The Wireless Communications channel is conﬁgured via the TAIP PC message.

5-6 CrossCheck GSM Operation ManualIQEvent Engine Overview5.3 Data LogThe IQEvent Engine maintains a Data Log in non-volatile, battery-backed memory.The Data Log is a circular log, where new entries overwrite the oldest log entries.The following types of data can be directed to the Data Log:•IQEE Event Reports containing an event number and the GPS location and time associated with the event.•TAIP TX messages routed from MDT input• IQEE conﬁguration and status data generated by Event Actions (TAIP queries) for example, counter values, timer values, discrete I/O states, conﬁguration parameters.Data Log entries can be retrieved and erased via a wireless comms connection or via the MDT serial interface. A facility is available to allow recovery from interruptions in lengthy retrieval sessions. Data Log control and retrieval is accomplished via the TAIP DL message.5.4 MDT Interface The CrossCheck GSM MDT interface allows connection to an external serial device, such as a PC/laptop or message terminal. The MDT interface can be conﬁgured in the following modes:•Normal mode—In Normal mode, the MDT interface is used for CrossCheck GSM conﬁguration and status. The default protocol is TAIP, which is the IQEvent Engine native protocol. IQEE can be conﬁgured, events can be reported, and Data Logs can be retrieved via TAIP messages. Other selectable protocols are TSIP and NMEA. •PAD mode—In PAD (Packet Assemble/Disassemble) mode, message text can be input to the CrossCheck GSM and output

CrossCheck GSM Operation Manual 5-7 IQEvent Engine Overviewfrom the CrossCheck GSM. All text input is partitioned into packets (according to PAD mode selections) and inserted into TAIP TX messages for routing to a base station or to the Data Log. TX messages received from a base station (or generated by IQEE and routed to the MDT) are stripped of their TAIP “wrapper.” and the remaining text data is output to the MDT.•AT command mode—In this mode, the MDT interface becomes an interface to the CrossCheck GSM’s internal GSM Comms module. The Comms module can then be used as a data modem. An AT command/response dialog can be used to set up data connections and transfer data via the GSM network.Conﬁguration of the MDT interface is controlled by the TAIP MT message.5.5 Discrete I/OTheIQEvent Engine provides discrete I/O support to trigger events and send control signals to external devices. Discrete inputs are de-bounced and transitions are registered once per second to provide Event Engine triggers. Digital outputs can be set active or inactive or pulsed with selectable pulse width and can be controlled on user demand or from a conﬁgured event occurrence.Discrete I/O control and status is accomplished with the TAIP SS message.5.6 Power ManagementThe CrossCheck GSM can be conﬁgured in power-save mode to prolong vehicle battery life. The power management strategy is conﬁgurable and is in effect only when the vehicle ignition line is not active, that is, when ignition is on, the CrossCheck GSM is also on.

5-8 CrossCheck GSM Operation ManualIQEvent Engine OverviewPower management can be conﬁgured for timed shutdown/wakeup cycles (for example, wake up every hour at 50 minutes past the hour, and stay awake for 10 minutes) and/or for wakeup from an external signal (for example, when discrete input 1 becomes active). Conﬁgurable shutdown delays allow orderly shutdown (for example, the Comms Activity Timeout speciﬁes the time to wait for completion of an active call before shutdown). Power Management controlled shutdown normally turns off all CrossCheck GSM components. However, a Comms Standby mode can be selected to allow the unit to shut down while keeping the GSM module powered on. The GSM module can then maintain network status and wake up the CrossCheck GSM on an incoming Ring. When Comms Standby is selected, the GSM module will remain On for the selected standby time following each controlled shutdown.Power Management is conﬁgured via the TAIP PM message.5.7 Password Protection Access to IQEE conﬁguration and status data can be password-protected. Each CrossCheck GSM can have its own password, or a common ﬂeet password can be assigned. When the password is set and password protection is enabled, the password must be sent each time a dialog is initiated via Communications Channel or MDT connection. Autonomous reports generated by the IQEvent Engine are not affected by password protection.Passwords are conﬁgured and sent via the TAIP PW message.

CrossCheck GSM Operation Manual 6-16 TroubleshootingThe CrossCheck GSM is designed to operate in the conditions found in vehicle applications. When installed and maintained properly, the CrossCheck GSM mobile unit provides years of trouble-free service. Invalid inputs at any input port (MDT, GSM, over-the-air) do not cause permanent loss of function of the CrossCheck GSM. When presented with inputs that exceed the scope of the appropriate speciﬁcation, the CrossCheck GSM will ignore the input or implement predictable and reasonable behaviors.The CrossCheck GSM utilizes watchdog timers on applicable tasks to reduce the possibility of processor “hangs.” When a fatal error is detected (or a watchdog timer expires) the controller will restart and attempt to resume normal operation.All fatal errors and unexpected restarts are logged, and can be inspected via the MDT port or over the air. (For more information, see the Extended Diagnostic Message 5 (X5) in the TAIP/IQEvent Engine Reference Manual.The CrossCheck GSM mobile unit has no user-serviceable parts. If a component fails, the CrossCheck GSM must be returned for repair to the authorized Service and Repair Center.Should the CrossCheck GSM fail to operate properly, the installer or service technician should troubleshoot the installation before returning any components for repair. This chapter provides some guidelines for troubleshooting common problems associated with the CrossCheck GSM’s operation. Potential operating problems might include:•No power

6-2 CrossCheck GSM Operation ManualTroubleshooting•Poor GPS reception•Poor GSM coverage•Communication failure with base•LED error indicators•IQEvent Engine programming errorIf the CrossCheck GSM mobile unit continues to operate poorly after following the troubleshooting guidelines described in this chapter, contact the CrossCheck GSM supplier for assistance. This chapter also describes the self tests available with your CrossCheck GSM.6.1 No PowerThe GPS and GSM LEDs on the front of the CrossCheck GSM should be illuminated if there is power to the unit. If both of these LEDs are off, it is likely that you do not have power to the unit. To correct this condition, check the conditions described in following sections.6.1.1 Cabling ProblemsMake sure the all cables are securely plugged into the proper unit connectors. Check for shorts and opens. Verify that you have proper pin and lug crimps.6.1.2 Connection ProblemsMake sure that all connectors are secure and that the power source is providing the correct voltage. Verify that crimps are done correctly.

CrossCheck GSM Operation Manual 6-3 Troubleshooting6.1.3 Fuse ProblemsVerify the integrity of the CrossCheck GSM 2-amp fuse (part of the power cable—P/N 40358). If you do not use the Trimble power cable, you are responsible for proper fusing of the CrossCheck GSM.6.1.4 Battery ProblemsMake sure your battery power source is generating sufﬁcient current to power your CrossCheck GSM (1.5A max at 12VDC without the Voice Upgrade Kit, 2.0A max at 12VDC with the Voice Upgrade Kit). Check BTU settings for possible problems. Check the under voltage/over voltage programmed range.6.2 GPS Reception ProblemsThe green GPS LED normally remains on when the GPS receiver is computing position ﬁxes and blinks once, every second, when not computing position ﬁxes. If the LED is always off, check the power connections.If the LED fails to turn on when the vehicle is not obscured from receiving satellite signals, check the conditions described in following sections.6.2.1 GPS Antenna LocationThe GPS antenna must be installed in a horizontal plane with a clear view of the horizon and sky. If a signiﬁcant portion of the horizon is blocked by something on the vehicle, try another location on the vehicle if the current location is suspect. For example, if the GPS signals are blocked by the air conditioning unit on a vehicle’s cab or the trailer connected to a tractor, the GPS receiver may have difﬁculty acquiring enough satellites for a position ﬁx. Move the antenna to a new location where it is not blocked.

6-4 CrossCheck GSM Operation ManualTroubleshooting6.2.2 JammingThe GPS antenna should be installed as far away as possible from transmitting antennas, including satellite communication, radar, VHF and cellular. These transmitters may emit jamming signals which interfere with the GPS receiver’s ability to track GPS satellite signals, which are very weak. Generally, the stronger the other transmitting device, the wider the distance required between antennas. For the CrossCheck GSM, Trimble recommends a minimum clearance of 46 centimeters (or approximately 18 in.) between the GPS and GSM antennas. Land-based transmitters, including microwave and television transmitters, can also interfere with GPS reception. If the vehicle is operating near an antenna farm, the CrossCheck GSM may temporarily lose GPS reception while the vehicle is in the vicinity of the transmitters. Reception should return once the vehicle moves away from the transmitters.If your GPS signals are being jammed, and moving does not correct the situation, the source of the jamming signal may be another antenna mounted too close to your GPS antenna. If possible, turn off the equipment using other nearby antennas to see if this corrects the problem. If turning off nearby equipment unjams your GPS signals, you need to relocate one or more antennas.6.2.3 Antenna Cable and ConnectorsA common problem is damage to the GPS antenna cable during installation. Inspect the GPS antenna cable along its entire length. Look for cuts or pinches in the cable or other signs of deterioration. Check the connectors for signs of stress and broken or bent center pins. If the cable is suspect, try a known good replacement cable.If you are using a cable from a source other than Trimble, ensure that its performance speciﬁcations meet those speciﬁed in Appendix A. Cables that do not meet those speciﬁcations inhibit the GPS receiver’s ability to track weak satellite signals.

CrossCheck GSM Operation Manual 6-5 Troubleshooting6.2.4 Defective GPS AntennaInfrequently, the GPS antenna may be defective. If the installed GPS antenna is suspect, disconnect the suspect antenna from the CrossCheck GSM and temporarily connect a known good antenna. If the reception signiﬁcantly improves, replace the defective unit and return it to Trimble for evaluation and repair.If you are using an antenna from a source other than Trimble, assure that its performance speciﬁcations meet those speciﬁed in Appendix A. Antennas that do not conform to those speciﬁcations, will inhibit the GPS receiver’s ability to track weak satellite signals. 6.3 Poor GSM CoverageIf the amber GSM LED blinks once every second, even when the vehicle is in an area with strong GSM coverage, check the conditions described in following sections. Also, try a known good antenna.6.3.1 GSM Antenna LocationThe GSM whip antenna should be installed in a vertical orientation with a relatively unobstructed clearance around the antenna. Try another location on the vehicle if the current location is suspect. Try another known good antenna.Even in areas with strong GSM service, there may be pockets where GSM service is poor or non-existent due to how the carrier builds their networks. Contact your local service provider for information on GSM coverage.

6-6 CrossCheck GSM Operation ManualTroubleshooting6.3.2 GSM JammingThe GSM antenna should be installed as far away as possible from other transmitting antennas including satellite communication, radar, and VHF radio. These transmitters may emit jamming signals which interfere with the GSM phone’s ability to track the GSM signal. If there are other transmitting antennas located on the vehicle, try moving the GSM antenna farther away from these antennas. Generally, the stronger the other transmitting device, the wider the distance required between antennas. 6.3.3 Antenna Cable and ConnectorsA common problem is damage to the GSM antenna cable during installation. Inspect the antenna cable along its entire length. Look for cuts or pinches in the cable or other signs of deterioration. Check the connectors for signs of stress or corrosion and broken or bent center pins. If the cable is suspect, try a known good replacement cable.

CrossCheck GSM Operation Manual 6-7 Troubleshooting6.3.4 Defective GSM AntennaInfrequently, a new GSM antenna could be defective or could become defective because it is prone to vandalism and other sources of mechanical damage. Inspect the antenna.If there are signs of damage, disconnect the antenna and temporarily connect a known good antenna.If the GSM service signiﬁcantly improves, replace the defective antenna.If you are using an antenna from a source other than Trimble, assure that its performance speciﬁcations meet those speciﬁed in Appendix A. Antennas that do not conform to those speciﬁcations, will inhibit the transceiver’s ability to receive and transmit. 6.4 No Data Communication with BaseCheck the conditions described in following sections if the CrossCheck GSM cannot communicate with the base, you can see that it is calling in data mode, and you have veriﬁed that it is calling the correct number.6.4.1 Base Modem ConﬁgurationConsult the modem manual for conﬁguration instructions. Each modem manufacturer has its own settings and control commands. Verify that your conﬁguration, PIN numbers, etc. are correct.6.4.2 Defective CrossCheck GSM UnitIn this case, the only remedy is to replace the CrossCheck GSM and return the defective unit to Trimble, or a local service center, for repair. Before returning the CrossCheck GSM, be sure to save the CrossCheck GSM’s conﬁguration settings, and remove your SIM.

6-8 CrossCheck GSM Operation ManualTroubleshootingIf you believe that the CrossCheck GSM is defective, ﬁrst move into an area with strong GSM coverage. Call the CrossCheck GSM from a regular phone. Be sure to use the data number for the SIM, not a voice number. Try a known good GSM antenna.If you hear tone when the CrossCheck GSM answers, then the CrossCheck GSM is operating normally. If you do not receive a signal tone, the CrossCheck GSM may be defective. 6.4.3 No Modem Connection with Base StationConﬁrm that the base station modem is conﬁgured correctly, and CrossCheck GSM unit is conﬁgured and operating correctly. Check to see if the proper base station phone number is programmed correctly.Conﬁrm the following:•Verify the base station software is calling the correct CrossCheck GSM telephone number. Often SIMs have both voice and data numbers. Conﬁrm that the base is calling a data number.•If you are using SMS, make sure the correct SCA is set. 6.4.4 Base Station SoftwareFleetVisionIf you are using FleetVision:•Check channel setup for proper settings.•Verify that the CrossCheck GSM unit is programmed correctly.•Check system for proper modem setup.

CrossCheck GSM Operation Manual 6-9 TroubleshootingOther Tracking SoftwareIf the base station is not using FleetVision software, the base station software may not be correctly integrated with the CrossCheck GSM. Contact your software vendor for assistance.6.5 Updating Firmware in the FieldYou can upload new ﬁrmware from a PC or laptop connected to the MDT port.For more information on updating ﬁrmware in the ﬁeld, refer to the Trimble website (http://www.trimble.com/products/catalog/mobile/xcheckgsm.htm) and follow the re-ﬂash instructions.6.6 LED Diagnostic ErrorsThe LED indicators are useful for diagnosing problems. The CrossCheck GSM mobile unit should be inspected by qualiﬁed service personnel if any of the situations described in Table 6-1 occurs.

6-10 CrossCheck GSM Operation ManualTroubleshooting6.7 Understanding Power-up TestsA series of basic hardware tests are run on power-up to detect fatal hardware errors. Flaws detected at this level, in most cases, will prevent the CrossCheck GSM from functioning normally.6.7.1 Power-up Self-TestPower-up self-test is initiated automatically on power-up following the startup initialization code. The controller outputs a prompt to the Table 6-1 LED Diagnostic Indicators LED Error Condition MeaningGSM LED Blinks for extended period of time while in a known good coverage area •GSM antenna cable may not be connected or damaged. Check the cable and the connectors. Try a known good GSM antenna.•You may be in an area of poor coverage.

The antenna cable may not be connected to the unit. Check for a damaged GPS antenna cable.•Turn the unit off and then back on again.•Replace the unit.Both LEDs are off •Check power source. •Check in-line power fuse. •Check for low voltage. •Try a known good unit. Both LEDs blink rapidly immediately after power upBuilt-in Self Test Failure: Cycle power. If condition persists, return to factory.

CrossCheck GSM Operation Manual 6-11 TroubleshootingMDT port. If an ESC is detected at the MDT port within a few seconds after displaying the prompt, the controller will then issue status messages via the MDT port, which can be displayed or printed by a diagnostic terminal (for example, a PC).The status message will indicate if the unit is working or not. If your CrossCheck GSM does not pass the power-up Self Test, gather the status message information and contact your service representative for help. If the CrossCheck GSM suffers a fatal error during start up (for example, memory failure) both LEDs blink at a faster than normal rate. These errors are occasionally caused by noise or power-supply transients that exceed speciﬁed ratings. If the CrossCheck GSM fails the power-up Self Test when installed but not on (for example) a test bench, examine the power supplied to the unit in the vehicle for excessive noise or ﬂuctuations.If you still have problems with your CrossCheck GSM, please send E-mail to Trimble (at Trimble_Support@Trimble.com) with a description of the problem. Please include all the details you can, such as the name of the product, serial number, part numbers, ﬁrmware version, LED states, and the like.

CrossCheck GSM Operation Manual C-1C TSIP ImplementationThe CrossCheck GSM supports the Trimble Standard Interface Protocol (TSIP) through the MDT/Aux port. Detailed information about TSIP and TSIP command and report packets is provided in the TSIP Reference, Trimble P/N 34462-00. TSIP is only supported through the CrossCheck GSM’s MDT/Aux serial port and should be used by advanced users only. As a binary protocol, TSIP is designed for computer-to-computer interaction. Note – The CrossCheck GSM supports a battery-backed conﬁguration block. All user-deﬁned GPS operating parameter settings and ﬂag settings are stored in the conﬁguration block. Soft resets (Command Packet 0x25) and powering the unit Off and On do not effect the settings stored in the conﬁguration block. The contents of the conﬁguration block can be requested by sending Command Packet 0x8E 0x6F, and the CrossCheck GSM responds by sending the conﬁguration block in Report Packet 0x8F 0x6F. For more information, refer to the TSIP Reference.

CrossCheck GSM Operation Manual D-1D NMEA ImplementationThe CrossCheck GSM mobile unit can output a selection of NMEA-0183 Version 2.1 sentences. NMEA-0183 sentences can be generated and output to the MDT/Aux serial port only, allowing the CrossCheck GSM to interface with external instruments.Note – The CrossCheck GSM cannot transmit NMEA-0183 sentences over-the-air.

D-2 CrossCheck GSM Operation ManualNMEA ImplementationD.1 NMEA-0183 Sentence StructureNMEA-0183 sentences are strings of comma-delimited text. Figure D-1 shows the structure of an NMEA-0183 sentence.

CrossCheck GSM Operation Manual D-3 NMEA ImplementationEach NMEA sentence includes a sentence ID to distinguish the sentence from other NMEA sentences in the data stream. The actual data included in NMEA-0183 sentences is placed in ﬁelds. An NMEA sentence contains several ﬁelds, and each ﬁeld is preceded by a comma character. The sample sentence in Figure D-1 contains six ﬁelds. NMEA sentences can include an optional checksum value which is useful for checking the integrity of the data included in the sentence. The sentence structure of the sample ZDA sentence, shown below and the sentence fields are described in Table D-1:$GPZDA,152145,21,05,1996,-7,00*50The NMEA-0183 sentence examples in this chapter are presented in the format shown in Table D-1. The structure of each sample sentence is shown in the paragraphs preceding the sentence structure table.Table D-1 Sample ZDA Sentence StructureField Description123456ChecksumTime, in UTC. (152145 in the sample sentence)Day, 01 to 31. (21 in the sample sentence)Month, 01 to 12. (05 in the sample sentence)Year. (1996 in the sample sentence)Local time zone offset from GMT, 00 to ±13 hours. (–7 in the sample sentence)Local time zone offset from, minutes. Fields 5 and 6, together, yield the total offset. For example, if ﬁeld 5 is ’–5’ and ﬁeld 6 is ‘15’, local time is 5 hours and 15 minutes earlier than GMT. (00 in the sample sentence)The CrossCheck GSM conforms to NMEA-0183 Version 2.1 which states that checksums are mandatory for all sentences. Checksum values are always included in output sentences, but are optional for input sentences.

D-4 CrossCheck GSM Operation ManualNMEA ImplementationThe numbers in the Field column represent the sentence fields in left-to-right order. Field 1 is the ﬁrst ﬁeld following the ﬁrst comma delimiter. In the sample sentence, ﬁeld 1 contains the UTC Time value (152145). D.1.1 Symbols and DelimitersSymbols and delimiters are used to identify or separate the various kinds of data included in the sentence. NMEA-0183 sentences always begin with a dollar sign character ($) character which is immediately followed by a sentence ID code. For the sample ZDA sentence, GPZDA is the sentence ID. The dollar sign character marks the beginning of a sentence. The string of comma delimited text immediately following the sentence ID code is composed of ﬁelds containing data. Each ﬁeld follows a comma character ( , ). For the sample sentence, the data ﬁelds are shown below:,152145,21,05,1993,-7,00NMEA-0183 sentences are always terminated with a carriage return and line feed. The carriage return and line feed pair mark the end of the sentence.

CrossCheck GSM Operation Manual D-5 NMEA ImplementationD.1.2 Checksum ValuesThe CrossCheck GSM conforms to NMEA-0183 Version 2.1 which states that checksums are mandatory for all sentences. Checksum values are always included in output sentences, but are optional for input sentences. The sample sentence, shown in Table D-1, includes a checksum value. An asterisk character (*) is used to delimit the last data ﬁeld from the checksum value (50 in the sample sentence). The checksum is the 8-bit exclusive OR of all characters in the sentence, including the commas, between but not including the ‘$’ and ‘*’ delimiters. The hexadecimal result is converted to two ASCII characters (0-9, A-F). The most signiﬁcant character appears ﬁrst.D.1.3 Field FormatsThe data values included in ﬁelds meet the format speciﬁcations established for the NMEA-0183 Version 2.1. Null FieldsNull ﬁelds are included in some NMEA sentences when no data is available for a particular ﬁeld. Null ﬁelds are empty and are usually reserved for transmitting data on a periodic or irregular basis. The comma delimiter for the Null ﬁeld is immediately followed by the comma delimiter for the next ﬁeld in the sentence string. The inclusion of Null ﬁelds in a sentence is important because many NMEA sentences contain a ﬁxed number of ﬁelds. NMEA sentence interpreters (software for processing NMEA sentences) expect to ﬁnd a ﬁxed number of ﬁelds in these sentences, and speciﬁc kinds of data in each ﬁeld. The sentence processing software assumes that no data is available for a particular ﬁeld when a Null ﬁeld is encountered while interpreting a sentence.

$D-6 CrossCheck GSM Operation ManualNMEA ImplementationLatitude and Longitude ValuesLatitude and longitude values are included in sentences in ddmm.mmmm format. Longitude is always represented as dddmm.mmmm in a single ﬁeld. Within the ﬁeld, degree values are in dd or ddd format, and minutes and decimal fractions of minutes are in mm.mmmm format.Latitude and longitude direction values (north, south, east, or west) are placed in a separate ﬁeld. Direction is a single character: ‘N’, ‘S’, ‘E’, or ‘W’ for North, South, East, or West.The datum for latitude and longitude is WGS-84 or NAD-83, depending on the reference station coordinates. In the U.S.A., the latitude and longitude coordinates are presented using the NAD-83 datum.Time ValuesTime values are in UTC (Universal Time Coordinated), and are inserted in sentence strings in hhmmss format, where hh is hours (from 00–23), mm is minutes, and ss is seconds.Other ValuesThe format of data included in each data ﬁeld is controlled by the NMEA-0183 Version 2.1 requirements for each type of NMEA sentence. The NMEA-0183 Version 2.1 standard should be considered to be the deﬁnitive resource for the format and content of the data ﬁelds included in sentences, therefore you should refer to the standard whenever a question arises about the structure of any NMEA sentence.$
