The SNRx10 is constructed in an ESD-protected environment. Most of the semiconductor devices in the instrument are susceptible to ESD damage.

ESD is generated in many ways.

For example, it can be the result of simple contact, the separation of materials, or the normal motion of people working with the device. Depending on the magnitude of the charge, device substrates can be punctured or destroyed by contact with, or by mere proximity to, a static charge. The result can be immediate destruction, early failure of the device, or degradation of device performance.

To prevent static damage or destruction:

• Take adequate precautions when you handle or service equipment that contains staticsensitive devices.

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

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

General Information and Safety

The RoHS initiative

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

What RoHS means to Trimble

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

What RoHS means to Service

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

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

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

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

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

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

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

• RoHS service parts will be a phase in process for non RoHS products. Use the original part defined for the non RoHS product first. Once these parts are consumed, the new RoHS part

boards pose special problems as they must also

will phase in as long as it is FULLY backwards compatible. The old part numbers will then be inactivated. Please, ALWAYS refer to the latest part list.

• RoHS compliant PC boards may be identified by the

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

• Service parts are defined as:

– SPR (Service Part Red) which is allowed in the EU to service an existing product

– SPG (Service Part Green) which conforms to RoHS.

– Those parts used within a product to repair or upgrade a unit’s performance. External

cables, accessories, and so on are not considered service parts.

The SNRx10 Radio Modem was designed to be RoHS compliant. The service parts list is located in

Operational Overview

The SNRx10 radio modem series completes the system component modernization of the GCS900 Grade Control System. It is designed to be backward compatible with SNR900, SNR2400 and SN450 radios. It is compatible with both the V6.xx and V10.xx GCS900 Operating Systems found on the Display Controller within the customers system. This radio series uses the traditional 8-Pin Bendix connector which plugs into the existing radio cable in the wiring harness. The radio communicates in the system harness via the CAN bus protocol.

The SNRx10 radio modem series is designed so both the 900MHz and 450MhZ models can receive CMR packets from a nearby Base. The 2.4GHz radio is used for communication with our Advanced Tracking Sensor products.

Theory of Operation

Different Radio Models Available

Due to the demand for different UHF radio requirements within different countries, Trimble has designed the SNRx10 radio modem series to be available with either one single radio frequency band or with a dual radio band option, all within the same housing

At the time of this release, the following models are available:

Note – Country Codes on the SNR series are set when the final part number of the unit is set during

manufacturing. Since this is a receive (RX) only product the country code on the SNR does not need to be matched to the country code of the Base. The SNR is designed to accept incoming signal from any country code. Therefor you cannot change the country code in the field and there is simply no reason to do so.

Theory of Operation

Mechanical

Mechanically the SNRx10 radio modem series is designed to meet the high vibration requirements of the Machine Control and Construction industries. It’s rugged housing was designed to accommodate up to two different radio modules. The series can be ordered with just a single 2.4GHz, 900MHz or 450MHz radio module or the 2.4GHz radio module can be paired with either the 900MHz or one of three 450MHz radio modules. The 450 series 63127-xx-24 comes equipped with an inactivated 2.4GHz radio module pre-installed. The customer can either order a dual radio and have it activated at time of purchase or pay an upgrade fee and have the option code for the 2.4GHz radio enabled later. Without the option being turned on the radio acts as a single 450MHz series radio. The 450MHz and 900MHz radios are mutually exclusive and cannot be combined into the same housing.

The 900MHz and 2.4GHz radios use the same whip antenna while the 450MHz series uses two different whip antennas. The 2.4GHz radio module is always installed on the left side of the radio (when viewed from the front) and either the 900MHz or a 450MHz radio module will be mounted internally on the right side, as shown here:

Fig. 3-5 Front view of a Dual SNRx10 series radio showing whip antenna location

Note – The connector jack on the radio for the 900MHz models use a standard TNC jack, the

450MHzmodel series uses a reverse polarity TNC connector. This means the center conductor pin is male.

Circuit Boards

Digital Board P/N 56889-00S:

The digital processor board assembly contains the memory that stores all of the programmed information, including firmware, Electronic Serial Number (ESN) and configuration options. The board also controls the flow of all I/O data that runs through the I/O panel assembly. Radio frequency settings, modem parameters and defaults are all held in non-volatile memory. The 2.4GHz radio modules plug directly into the digital board. The 4xxMHz series radio module use a mounting bracket and adaptor board to interface to the digital board. The 900MHz radio module board just uses a special mounting bracket so it can be aligned properly to plug into the digital board. The power supply board plugs into the digital board by a 40 pin tower adaptor.

Radio Modem Boards

The 900MHz radio module (P/N 53195-01)Sis designed and manufactured by Trimble Navigation. The 2.4GHz radio module (P/N 64327-00S) and the 4xxMHz series (P/N’s 60384 -62S, -64S, -66S) radio modules are each designed exclusively for Trimble by separate OEM manufactures. The 4xxMHz radio modules are mounted on a carrier board (P/N 58585-00S) that interfaces to the digital board. These reliable field proven radio modules have been used in previous Trimble designs such as the SNR2400 and the SPSx5x radio series products.

I/O Panel Assembly P/N 59931-00S

The I/O panel board assembly is designed as a means to firmly mount the 8-Pin Bendix connector to the top housing and provides built in PTC overvoltage protection and EMI noise suppression on the data input/output lines from the digital board. GCS900 main system harness power is routed between the ignition switch and enters the power supply board through the I/O panel assembly.

Power Supply Board 58480-00S

The power supply board generates multiple DC voltage outputs of 1.5V, 2.5V, 3.3V and 5.0V to the various circuits on the PC boards found inside the SNRx10 . The power supply board does have overvoltage protection.

General Troubleshooting

Always check the most obvious basic system level problems before investigating more complex troubleshooting issues. Some tests should be performed by the customer or dealer within the customers system before returning the radio in for repair:

1. Is the radio power cable plugged into the SNRx10 and the system ignition turned on?

2. Use a voltage meter to check that between 12VDC to 24VDC is coming out of Pins A and B of the 8-Pin Bendix connector on the radio power cable of the customers construction equipment. If there is no voltage could a system fuse be blown?

3. Check that the following radio settings are correct between the Base radio and the SNRx10:

– Network Channel between Base and Rover are the same.

Troubleshooting

– Baud Rate, Stop Bit and parity are the same.

– Radio Protocol is the same.

– The active radio setting on the SNRx10 matches the radio frequency of the Base. For

instance if you are interfacing a 2.4GHz radio but on your dual frequency SNRx10 the active radio setting has been left set at for 900MHz radio the interface won’t work until you change the active radio to be 2.4GHz.

LED Status Indicators

The SNRx10 has an LED on the front side of its housing that is used as a status indicator as shown below:

Maintenance and Repair

The top housing itself is not offered as a service part. However there are some parts that should already be installed on a post-production units and double-checked before reassembling the radio. Especially if the UUT failed a pre-repair seal integrity test or some mounting studs backed out during disassembly. Make sure the following parts are already in place in the top housing and torqued to their proper specification:

Short mounting studs installed

The two short digital board mounting studs (P/N 61954-00S) should already be installed, See drawing:Top Housing Assembly, page 63as needed.

• If the studs are loose or reused, apply Loctite 425 (P/N 31345-00S) on each stud

• Using a 5/16” socket on a torque wrench set to 11 in-lb +/- 10% (124 N-cm), turn each stud clockwise until the torque wrench clicks.

• Wait a minute or so and perform a second round of torquing each stud.

Physical Inspection

To perform a physical inspection check for the following things:

• Cracked top or bottom housing

• Damaged pins or threads on the Bendix connector.

• Damaged TNC connectors.

• Damaged, loose or missing TNC covers on single radio models.

• Cracked or missing LCD pipe window.

• Signs of water damage externally and/or internally, if so, do not power UUT up.

• Shake unit and listen for anything loose inside, if there is, do not power UUT up.

• Note whether there are missing or damaged S/N and/or P/N labels.

If the UUT passes all of the inspections above it has passed the physical inspection. If the UUT has not passed all of these tests make a note of which ones failed and repair them as needed when and if repairs are performed.

Seal Integrity Test

For a complete description on setting up the Seal Integrity Test, see Seal Integrity Test, page 107.This section assumes the kit itself is assembled and ready to use.

The Seal Integrity Test should be used as:

• Pre-Repair Qualification Test: This is a required test to see if the UUT is sealed properly before starting a repair. If a UUT fails a pre-repair test, it should be determined whether moisture could be inside and if it is then do not power the unit up.

• Post-Repair Qualification Test: A seal integrity test is always required as part of the final test procedure. Make sure the UUT passes this test and that any failures in the pre-repair seal integrity test have been fixed.

To perform a seal integrity test refer to Seal Integrity Test, page 59

As per the test, if the receiver remains sealed at both +5 psi and -5 psi each for 30 seconds or longer without losing more then 1.0 cc of air, it has passed this test.

Retrieve/Restore Radio Diagnostic Information

Before starting a repair it is best practice to save or print out the radio diagnostic information for the UUT so a permanent record of the original settings and channel frequency table are saved for future reference. Use the radio interface cable and Winflash as per section Retrieve Radio Diagnostics

Information, page 98, which is shown again here:

1. In Winflash, highlight Retrieve Radio Diagnostics Information and then hit Enter.

2. Click on Save or Print to print out the customers current configuration and save it as a reference. A print out will be sent to the default windows printer.

Voltage and Current Tests

Many service providers that currently repair the Sitenet series radio’s may have created this test cable already. If you need to assemble this cable order the above parts and then follow the instructions in

Voltage Test Cable, page 129.

Preparing to Run the Tests

To run voltage and current tests efficiently it is recommend that a variable power supply is used with the following minimum specifications:

• Min/Max Voltage Range: 0 - 40V DC or higher.

• Minimum Current: 3A or higher

• Digital Display for both voltage and current readings.

A radio voltage test/interface cable with a power input is also required to perform these tests. An 8Pin Bendix to Lemo adaptor along with one of the following radio cables (these are Sales parts, not Service parts) will need to modified for this test:

• 40282-01: Cable - Radio, 1ft., 0 shell 7-pin LM(F) to 8-pin BD(F)

• 59044: Cable - 1.5m, DB9(F) Y to 0S/7-pin LM(M) to Power Jack (RoHS Compliant)

• OR 32345: Cable - 1.5m, DB9(F) Y to 0S/7-pin LM(M) to Power Jack (no longer sold, the above part took its place but is backward compatible).

Once the test cable has been built prepare it for testing by doing the following:

• With the variable power supply turned off, plug the black banana jack into the ground terminal of the variable power supply.

• Plug the red banana jack into the positive terminal of the variable power supply.

• Attach adaptor 40282-01 to the modified test cable if hasn’t been plugged in yet.

• Without plugging in the test cable to the UUT, turn on the variable power supply and set the voltage to 12VDC. If the variable power supply has a current limit setting make sure it is set to 3A or higher.

• Now set the power supply to standby or turn the power off until you begin running tests. From this point forward as we describe the following tests, we will assume the power supply is set at 12V DC, 3A or higher and in standby mode at the beginning of each test unless specified otherwise.

Running the Tests

Voltage Input vs. Current Draw

The purpose of this test is to measure the current draw of the UUT when it is powered up at standard GCS system voltages. If the current draw is within specification then the UUT has passed these tests. To perform these tests follow these steps:

Current Draw at 12VDC:

1. Plug the 8-Pin Bendix cable into the SNRx10.

2. Turn the power supply on. If the current jumps like there’s a short then shut the power supply off immediately. Otherwise proceed to the next step.

3. At 12VDC the current should be about 470ma +/- 15ma to pass this test

4. Place the power supply back to standby mode or shut it off.

Current Draw at 24VDC:

1. Turn the power supply on. If the current jumps like there’s a short then shut the power supply off immediately. Otherwise proceed to the next step.

2. At 24VDC the current should be about 260ma +/- 15ma to pass this test.

3. For easy transition to the next test keep the variable power supply “on” and at 24VDC and proceed to the next test.

Overvoltage Test

The purpose of this test is to ensure that the overvoltage protection circuit works on the SNRx10 and whether the UUT recovers after the overvoltage source is lowered down to within the normal input voltage range of 12-24VDC.

To test the overvoltage protection perform the following steps:

1. Turn the variable power supply voltage up to 32VDC. Slowly continue increasing the voltage and observe the following:

1.1. The overvoltage protection circuit should kick in somewhere between 32.40 and

35.5VDC.

1.2. Now slowly lower the variable power supply voltage back down toward 32VDC. The

overvoltage protection circuit should turn off and the unit should power up again somewhere between 32.4VDC and 24VDC. If the UUT’s overprotection circuit kicks

in within the specified voltage range above and recovers after the input voltage is lowered back within normal input voltage range then the UUT has passed this test.

1.3. If overvoltage protection never kicks in or the UUT shorts out then turn off the variable

powers supply immediately. The UUT has failed this test and the power supply board and/or front I/O panel should be troubleshot further.

Service Manual

P/N 59646-SVC, Revision BPage 76SNRx10

Page 87

Chapter 8

Under voltage Test

The under voltage test checks to see how low the voltage can get before the SNRx10 shuts down. The basic objective at that it shut down at a input voltage that is quite a bit lower then 12VDC, usually starting at 9.25VDC or lower. Perform the following steps:

1. Starting at 12VDC, slowly turn the variable power supply downward and observe the following:

1.1. The UTT shuts down at 9.25VDC or lower. Usually it shuts down at around 8.4VDC.

1.2. Once the UUT shuts down, turn the input voltage back up and observe that the UUT

powers up at approximately 8.70VDC +/- .50V. If the UUT powers down and then

powers up within this range then it has passed this test.

Performance Verification

LED TEST

The purpose of this test is to ensure that the status LED on the front side of the radio is working and not burn out. It’s simple to run this test:

1. Turn the variable power supply on to power up the UUT.

2. Make sure that the light pipe “lens” itself is not scuffed up or damaged, if it is, replaced the light pipe as per Light pipe is installed, page 44

3. If the unit is not drawing normal current at 12 or 24VDC and the LED is not lit, this could indicate a shorted power supply or other problem and the unit will require additional troubleshooting.

4. If the LED lights up and remains solid, and the unit is actually powered up, then the

UUT has passed this test.

The LED will not remain solid if specific data communications occur such as when the radio is receiving CMR packets. A more detailed documentation of different radio status, as specified by the LED is located in Below is the same table as noted in Led Status Table:, page 28.

Serial Port Interface

The purpose of this test is to make sure that the RS232 serial port(s) are working on the UUT. The current SNRX10 radio modem series has two serial ports and one CAN buss port. The firmware itself identifies the serial ports as COM2 and COM3.

The test itself can be run using Hyperterminal as follows:

1. In Windows go to Start\All Programs\Accessories\Communications and click on Hyperterminal. In the “New Connection” window enter the name Serial Port Test select an Icon of your choice, click on Ok.

2. In the “Connect To” window use the drop down menu to select the COM port on your computer that you will be using for this test and click Ok.

3. In the “Properties” window make the following settings:

– Bits Per Second (Baud rate): 38400

– Data Bits: 8

– Parity: 1

– Stop Bits: 1

– When all settings are complete click OK. The Hyperterminal window will come up.

Note – At this point the radio data test cable 40942-03 must be used because it has two

separate serial port cables labelled I/O and GPS. These cables are hard-wired specifically to serial port 1 and serial port 2 of the SNRx10. As mentioned previously the SNRx10 firmware identifies the serial ports as COM2 and COM3.

4. To test COM2, plug in the DB9 marked I/O on test cable 40942-03 into the COM port of your computer. On your computer keyboard hit Cntrl and Break to send a query to the SNRx10. If COM2 is working it will report back information about the UUT and mention COM2. If this occurs then COM2 is working and has passed this test.

5. To test COM3, plug in the DB9 marked GPS on test cable 40942-03 into the COM port of your computer. On your computer keyboard hit Cntrl and Break to send a query to the SNRx10. If COM3 is working it will report back information about the UUT and mention COM3 directly behind the any previous information sent to Hyperterminal such as COM2 from the previous step. If this occurs then COM3 is working and has passed this test.

CAN Bus Test

Performance Verification

This test makes sure that the CAN Bus line between the digital board through the I/O port assembly is working properly. The only real way to test CAN at the system level is by using the GCS Test Box with GCS900 cable set: P/N 0690-1003 or by plugging the SNRx10 into a genuine GCS900 main system harness that has been proven to work properly.

The following steps assume that a GCS Test Box system with GCS900 cables is being used for this test:

1. Make sure the GCS Test Box is setup for a single or Dual MS980 or MS990 system including the rooftop SN radio cable that comes in the kit (P/N 0395-9470-150.

2. On the CB430, go to the Setup Menu\Configuration\Diagnostics screen.

3. If a sitenet or other Trimble radio is already plugged into the harness unplug it and then plug in the UUT. The SNRx10 radio should register as connected in the diagnostics screen as shown here:

Switch Active Radio

This test is for combination radio models only. Skip this test if the UUT is only a single radio model. This test proves that both radio’s in a combination model are configured and can be

operational.

If the UUT is a 900MHz/2.4GHz or a 4xxMHz/2.4GHz model then perform the following steps to make sure each radio can be selected for use:

1. Use Winflash as per Change Active Radio, page 100, if you can successfully switch back and forth between the two radio’s then the UUT has passed this test.

1.1. If the 2.4GHz radio is not listed as a selection then it will need to be reactivated as per

Option Code to Activate 2.4GHz Radio, page 96

1.2. If the 900MHz or 450MHz radio does not appear as a selection then there may be a

problem with the radio model or overall part number configuration. Further troubleshooting is required.

2. When this test is complete set the active radio back to whichever one the customer had activated when the radio was received for repair as per the original diagnostic screen printout.

Compare S/N and P/N to Housing Labels

To be comprehensive during performance verification it is best practice to compare the part number (P/N) and serial number (S/N) programmed inside the UUT with the external labels listed on the outside of its housing to make sure that they match each other as well as the SWO or RMA that is

being repaired. To do this simply use Winflash to run Diagnostics as per Retrieve Radio Diagnostics

Information, page 98 and check the following:

1. Check that the P/N matches the part number label on the housing and the SWO.

2. Check that the S/N matches the one on the housing and the SWO.

3. If all of these match then the UUT has passed this test.

– If the P/N or S/N does not match the housing determine if you programmed the unit

incorrectly. If the UUT does not match the SWO or RMA then did the paperwork get matched with the incorrect unit?

GCS Test Box: Radio System Bench Test

A system bench test can only be performed by using the GCS Test Box with GCS900 cable set (P/N 0690-1003) or by plugging the SNRx10 into a genuine GCS900 main harness found on a construction vehicle that has been proven to work properly.

The following steps assume that a GCS Test Box system with GCS900 cables is set up as follows:

1. Set up the GCS Test Box with GCS900 cable set as per the GCS Test Box Instructions and Service Manual (P/N 0690-1010).

2. The test system should already have a working Sitenet or SNRx10 radio in it and be receiving CMR packets from a Base in the repair shop and this should be shown as an Amber Led Radio Light flashing at 1Hz on an MS990 or MS980 as outlined in Chapter 8, page - 127 - 128 of the MS990 service manual.(P/N 55760-SVC Rev A) and in Chapter 8, page114 - 116 of the MS980 service manual (P/N 47950-SVC, Rev B).

3. Match the network ID of the UUT to the network ID of the Base that is transmitting the CMR packets by using Winflash or the Machine Radio Configuration utility found under the Setup:Installation menu of the CB430.

4. Plug the UUT into the radio test cable coming from “Rooftop 1” or “Rooftop 2” on the GCS Test Box.

5. Observe on the MS990MS980 that the radio light begins flashing at 1Hz, if it does the UUT has passed this test.

Note – If a service provider does not have a Radio Throughput Test Kit Model II (P/N 65306-

00S) then this GCS Test Box System Test is the minimal required test that can be done in the repair shop at the workbench to verify that the radio can receive CMR packets.

Radio Throughput Test

Trimble Service Technologies is developing a test kit called the Radio Throughput Test Kit Model II that can be used to measure the packet throughput performance of all current Trimble radio products at the test bench. By using a combination of fixed attenuators along with a variable one, the need to perform a baseline test out in the field by placing the UUT a certain distance away from the base so that it is in the “fringe area” of operation is replaced by using the attenuators to degrade the signal enough so that it duplicates as if the radio is physically placed in the “fringe area”.

Radio Throughput Test Kit Model II is still under development and will allow throughput testing of

2.4GHz, 900MHz and 4xxMHz Trimble radio products. The only radio throughput test available for SNRx10 radio-modem products at this time is for the 2.4GHz radio by using our previous Radio Throughput Test Kit (P/N 58829-00S) that was developed for testing the SNR2400 radio. This test kit can be setup to use the SNR2400 as a Base and an SNR2410 as a Rover.

Note – General recommendations: If you already have radio throughput test kit P/N 58829-00S then

go ahead and use it for a throughput test as noted below If you do not have this kit yet then we recommend that you follow the GCS Test Box system level test as perGCS Test Box: Radio System Bench Test, page 81and wait to purchase the Radio Throughput Test Kit, Model II. When this test kit comes out it will allow our radio service providers to test all three radio frequencies: 2.4GHz, 900MHz and 4xxMHz,instead of just 2.4GHz.

Radio Throughput Test: SNR2400 Base + SNR2410 Rover

The SNR2400 radio is designed to interface with an ATS advanced tracking sensor and does not use CMR™ packets for communication. Instead it is set to use ATS Interface protocol as the output. In addition to this, this was Trimble’s first generation 2.4GHz radio module and the internal command set is a bit different then our current 2.4GHz products. As a result, when using the SNR2400 as a Base it requires a different throughput test utility to run the performance verification test.

To run the throughput test the following test software must be installed on the test computer:

• Wit2410Test.exe ver. 0.74

• SNR_Base.bat

•SNR_Rover.bat

Setting up the SNR2400 as a Base

The following assembly instructions are for the SNR2400 Radio Throughput Test Kit only, P/N 58829-00S.

Note – You cannot use the original Wit2410Test.exe ver 0.73 and it’s associated batch files when

running a throughput test with the SNR2410. You must use v.074 and the new batch files it comes with.

1. Take one NMO to N adaptor and fasten it to the top of the SNR2400 and lightly tighten with pliers.

2. Tighten one 50dB attenuator, one 10dB attenuator and one 3dB attenuator onto the N side of the NMO to N adaptor on the SNR2400. A throughput test between an SNR2400 as a Base and a an SNR2410 as a Rover requires approximately 113dB of attenuation.

3. Tighten a TNC to N adaptor onto the N connector of the 50dB attenuator from Step 2.

4. Fasten one end of the RF Cable onto the TNC connector (from Step 3) on the SNR2400.

5. Plug the AC adaptor into a power source and then plug it into the power jack on the RF interface cable (40942-03).

6. Plug the DB9 cable marked GPS into COM1 on the test computer.

7. Plug the 8-Pin Bendix connector into the SNR2400 when you’re ready to start the test.

Setting up the SNRx2410 as a Rover (Customer’s UUT)

1. If this is a dual radio product you must first set up the 2.4GHz radio as the active radio using Winflash. Refer to section Change Active Radio, page 100

2. Use Winflash to change the Radio Protocol to ATS as per section Change Radio Protocol,

page 98

3. Tighten the second 50db attenuator onto the other end of the RF cable.

4. Screw the TNC to N Reverse Polarity adaptor into the 50dB attenuator

5. Fasten the TNC end of the adaptor onto the 2.4GHz TNC RF jack on the SNR2410.

7. Plug the DB9 cable marked GPS into COM2 on the test computer.

8. Plug the 8-Pin Bendix connector into the radio when you’re ready to start the test.

Running the Throughput Test

Activating the Rover

Note – You must activate the batch files in the order shown here or it will lock up your computer.

1. Dial in 113 dB of attenuation on the variable attenuator.

2. Double-click on the SNR_Rover.bat file. Observe that the following takes place in the Rover DOS Window Figure 8-3:

– Opening COM2: The default serial port is set to COM2 in SNR_Rover.bat file.

Whichever COM port is set in the batch file should be reported here.

– Product ID String: The UUT should be identified as the SNR2410 here. If it is not the

Base may be plugged into COM2 instead of the Rover.

– Setup complete, running: This should be reported once communication is established.

3. Press the “L” key on the computer keyboard, this places the UUT in “Listener” mode:

– Listen Mode (RX Only): ON: After pressing the “L” key, ON should be reported. If it

reports OFF then press the “L” key again until ON is reported.

Note – Placing the Rover in “Listener” mode is a new step compared to using the old

Wit2410Test.exe utility that was used with the SNR2400. You must perform this step or the test computer will LOCK UP.

Activating the Base:

1. Double-click on the SNR_Base.bat file. Observe that the following takes place in the Base DOS Window:

–

– Opening COM1: The default serial port is set to COM1 in the SNR_Base.bat file.

Whichever COM port is set in the batch file should be reported here.

– Product ID String: The SNR2400 should be identified as the product here. If it is not

the Rover may be plugged into COM1 instead of the Base.

– Setup complete, running: This should be reported once communication is established.

You will then see some symbols appear an the screen as packets are sent.

– Once the Base Window is activated, other then verifying packets are being sent, this

window is no longer really needed and can be minimized if desired.

Analysing the test results

Return to the Rover DOS Window and perform the following steps, see Figure 8-5, page88:

1. Allow the UUT to continue its throughput test for 10 minutes are at least 500 packets.

2. Observe the following:

– When the Rover drops a packet red “D’s” will be reported in the Rover DOS Window.

This is normal.

– Received # Packets: The number of packets sent/received in intervals of 50.

– Lost #: This is the overall number of packets lost since the test was started. Each time a

packet is lost it is counted here.

– Total # for %: The total number of packets sent since the test began and the overall

percentage of throughput packets since the test began. This part of the test should read 95% or higher after running the test for 10 minutes or at least 500 packets.

– Last # = %: This section tells the percentage of last batch of 50packets that passed the

throughput test. This contributes to the overall percentage passed since the test began.

Note – Although the recommended attenuation setting is 113dB this may vary by up to +/-

2dB. If your bench setup consistently has red “D’s” and never passes at 95% or the Rover DOS Window always shuts down, you may need to dial in only 111 or 112 as the attenuation setting for your workbench since 2.4GHz radio products have a dramatic cutoff point when operating at the fringe. Try several known good units to arrive at your optimum attenuation setting. Once it is established you should not have to change it during testing anymore.
