∇ Setting up the system

This chapter will describe the steps for setting up and configuring the voice quality measurement system. Please install the Nemo Outdoor software and the DMX 6Fire USB driver first.

♦ Note that it is very important for the laptop to fill the hardware requirements stated above; the laptop needs to have Core Duo Processor 2.0 GHz or AMD PCU, or more powerful.

INSTALLING THE DMX 6FIRE USB DRIVER IN WINDOWS XP

♦ Do not connect the USB connectivity cable to your PC until the driver installation is complete. However, power can be switched on in the sound card.

1. Before you start, ensure that your Windows XP version is up to date. Right-click the My Computer icon and choose Properties from the context menu. The System Properties dialog appears, in which you can check your current service pack version. You can also enter the System Properties dialog by going to Start | Settings | Control Panel | System. It is important for Windows XP Service Pack 2 (SP2 for short) or Windows Vista to be installed on your computer. If this is not the case, please contact Microsoft (www.microsoft.com) to update your system. For Windows, this is generally free of charge.

2. The driver installation file is found on the Nemo Outdoor installation CD in Nemo Outdoor\Drivers and Specific Softwares\TerraTec DMX 6Fire USB sound card driver. Please note that this specific version of the driver needs to be used.


3. Double-click on the installation file. The installation wizard will now display its welcome message.

4. The default destination for the installation is specified in the following window. If you prefer another folder, select Browse... and choose the corresponding directory. Then, click Install.

5. You can disregard the safety warning without concern. Click Continue Anyway to continue.


6. The driver is now installed in the system, and as soon as the message below appears, you can connect the DMX 6Fire USB to your computer's USB 2.0 port using the cable provided. If Nemo Multi hardware is used, sound card can be connected also to the Multi unit. Windows XP will automatically recognize the device as new hardware and open the driver installation dialogue.

7. The Windows Found New Hardware Wizard asks what driver to use for the new hardware component. You do not have to search for the driver online. The next window asks about the driver for the DMX 6Fire USB hardware. Next, select Install the software automatically [Recommended] and confirm with Next.

8. Then, just to be safe, a new system restore point is set. Nothing to be concerned about—this is a standard precaution.

9. This concludes part 1 of the installation, so click Finish.


10. This returns you to the installation wizard, as only the drivers for the USB controller have been installed; now, the drivers that make the controller a USB audio device are installed. Here, too, select Install the software automatically to install the second batch of drivers.

11. Again, you can safely ignore the message that the software did not pass the Windows Logo test.

12. Click Finish to complete the installation of the drivers.

13. Once the drivers have been installed, the DMX 6Fire USB should appear in the device manager with the following entries. Go to Start | Control Panel | System | Hardware and click the Device Manager button.

14. After installation remember to check that the GAIN1 and GAIN2 controls are adjusted to the minimum and the PAD switches are in the OFF position in the TerraTec Sound Card front panel.


15. Note that the volume level of the test terminals needs to be adjusted according to the table below during a voice call:

Terminal Volume level

Nokia 3500, 6120, 6121, N85, N85 US, N95, N95 US, N96, N96 US, N97, N97US

8 / 10

Nokia 6720(US), C5, C5-03, C7-00, 500 10/10

LG C680 3 / 8

LG KX206, C676 4 / 7

LG VX8350, VX8360 8 / 8

Datang DTM 8120 2 / 5

Huawei C7600 7 / 7

Leadcore LC 8130E 2 / 5

Samsung SGH-U800 3 / 7

Sony Ericsson Xperia arc S (LT-18i) 6 / 6

16. Start TerraTec DMX 6Fire USB Control Panel from Start | TerraTec | DMX6FireUSB.

17. From the control panel set the settings as in the screen shots below. Remember to also pay attention to the bottom part of the panel.


18. Input settings:

• Set Input ½ and Input ¾ levels to +5dB

• Set the Waveplay ½ and Waveplay ¾ levels to -5dB, except

• with Datang and Leadcore: -13dB

• with Samsung SGH-U800: -5db -> -10db

• with Sony Ericsson Xperia arc S: -24dB

• Unset all routing buttons at the bottom of the panel except set Waveplay 1/2 routing to 1/2 and Waveplay 3/4 routing to ¾

• Note that the volume on the Datang 8120 and Leadcore LC 8130E needs to be adjusted to level 2 (2/ 5) during a voice call. With the Datang 8120 and Leadcore LC 8130E terminals the TerraTec control panel settings are different from other terminals. If the system is used simultaneously with other terminals, unset the LINK buttons below the input/waveplay settings and you can change waveplay settings by channel. This way you can adjust the waveplay settings separately for the Datang terminal without affecting CDMA or GSM/WCDMA terminals.


19. Output settings:

• Set all Output levels and Master to 0dB

20. From Miscellaneous | Asio | Asio Latency, select Maximum (8.0ms 384 samples) and close the Asio Latency window. Now you can start Nemo Outdoor. You can leave the DMX control panel open or close it.

♦ Note that if there is a system that measures acceleration in the laptop and which causes the hard disk to stop when jolted, it should be turned off. Otherwise there may be breaks in the measurement files.

21. With the Lenovo T61 laptop you can turn this system off by going to Start | ThinkVantage Productivity Center and selecting Security | Protection and Recovery | Protect my hard-drive [ ] Enable Active Protection System.


22. Next, in Nemo Outdoor add a terminal by going to Measurement | Add New Device | Phone In the Phone Properties dialog select the two ports assigned to the mobile as Trace Port and Modem Port. You can check the ports from the Phone and Modem Options dialog (Start | Settings | Control Panel | Phone and Modem Options, Modems tab). Select the port with the bigger number as the modem port and the port with the smaller number as the trace port, e.g., COM100 as trace port and COM101 as modem port. Next, select the Sound card channel item. You will see a list of numbered options from channel 1 onwards. Select the channel based on to which LINE IN and LINE out jack you connected the audio cable in the sound card. You do not need to select anything in the dial-up connection fields unless you are also performing data transfers. In this case please refer to the Nemo Outdoor Dial-Up Networking Setup Guide for further information.

23. Select Measurement Properties | Voice number | Properties.

24. Click OK in the Measurement Properties dialog. You are now ready to perform voice quality measurements.

♦ Note that you need to add and configure each mobile separately. If you have several mobiles, make sure that you select the correct channel for each mobile.


♦ Note that if you are using more than two mobiles for voice quality measurements, Nemo Outdoor Multi is needed. Please refer to the Nemo Walker and Multi Lite User Manual for information on the Nemo Outdoor Multi system.

♦ Note that when you are using a separate 300W inverter, it is recommended that the computer and sound card be connected to the inverter prior to starting measurements. For example, if the computer is connected to the inverter during a measurement, it is possible that it causes a temporary supply voltage disconnection. This further risks an interruption in the reception of MOS values.

REQUIRED HARDWARE WITH TERRATEC DMX 6FIRE USB 2.0 SOUND CARD

♦ Note that the USB sound card can handle the maximum of four terminals simultaneously

♦ Note that only one USB sound card can be connected to the computer at a time

♦ Do not connect the USB connectivity cable to a USB 3.0 port as this may distort the audio sample.

♦ Note! If terminals report lower than expected MOS values in Voice Quality measurements, it may result from too high CPU usage on the computer. First of all, an Intel® Core Duo processor T2500 2.00GHz or higher is required for voice quality measurements. If you suspect that the reported MOS values are too low and you are using multiple terminals and a scanner simultaneously, try the following. First, if you have many applications running on the laptop, try closing the unnecessary ones. Next, disconnect the scanner and try testing with a single terminal to see if the MOS values improve. Proceed with testing with 1-4 terminals without using the scanner simultaneously for optimal MOS results.
