Testing Procedures

This procedure is used to determine the basic functionally of a four-channel TDOA Geometrix Wireless Location

Sensor (WLS) after installation has been completed.

Equipment Required

One Laptop Computer (See Table 2 for description)

One Crossover Cable (See Table 2 for description)

One Loopback Connector (See Table 2 for description)

Initialization

The link between the computing device and the WLS needs to be established. The following steps will establish

that connection.

Step 1.

At the DeskTop, right click on the Network Neighborhood icon and select properties. Depending

on the operating system, the keystrokes will differ slightly as to network setup.

Step 2.

Select the TCP/IP NIC.

Step 3.

Type the IP address of 10.1.1.200, and a subnet mask of 255.255.255.0.

If the GCS is in place and connected to the network, and the WLS is properly connected to the network, the green

online light on the front of the unit will be illuminated a few minutes following power-up.

Step 4.

Connect the WLS to a computing device via a crossover cable and plug into the10-

Base-T port on the rear panel of the WLS.

Step 5.

Power up the WLS.

Step 6.

After the computing device has booted up, select the QvtTerm plus in the systems

application menu.

Step 7.

Open a session and enter an IP address of 10.1.1.1 in the address window of the WLS to be

tested.

Step 8.

Select default in the configuration window, and click the OK button. This will bring up the login

prompt.

Step 9.

Enter root and a # prompt will be displayed.

When power is applied and connectivity is established between the GCS and WLS, the green online LED will

illuminate on the front panel. This will take roughly 1 minute. When this occurs the GCS will perform codecheck,

which will determine if the software is up to date with the latest software. At this point the GCS will notice that the

software is not up to the latest software and will begin downloading new versions of code to the WLS. After the

code has been downloaded to the WLS, a reboot is issued and the online LED will go off. When the WLS boots

up once again and establishes connectivity to the GCS the online LED will illuminate once again. These

processes should be completed in roughly two minutes. If this process fails, login to the WLS as above and type

the command ./stop_reboot. If all indications are correct, proceed to Step 10.

Step 10. At the # prompt enter the command: start The program will go through a series of initializations and when the screen reads started watchdog, hit the enter key and a # prompt will appear. Step 11. At the # prompt enter the command: ./stop_reboot This will stop the unit from rebooting if the unit does not see a network connection. Step 12. At the # prompt enter the command: ./stop_processes . Step 13. Type pwd on the command line. Step 14.

Step 3. Remove the loopback connector. Step 4. Install the 9 pin loopback connector for the COMM test. See Diagram 5, page 47 for pin connections. Step 5. When at the # prompt, type the command: testCOM. Watch for pass/fail reply. (Loopback Succeeded) Step 6. Remove the loopback connector. If the data reads anything other than the above, contact engineering to determine the severity of the problem. Testing The BPU Board Step 1. Change directory with the command: cd /ram/bpu/qnx/bin. Step 2.

Spectrum Plot Step 1. When at the # prompt, type the command: start. Step 2. When at the # prompt, type the command: ./stop_reboot. Step 3. When at the # prompt type the command: menu. This will be the main menu. Step 4. Select 1 Collect signal Info. This brings up the collect menu. At this point data needs to be entered in certain fields, so the system can make data collects. Step 5. Select 4 to enter the face of the antenna array. This will test all three faces receiving different frequencies.

Step 3. When at the # prompt, type the command: menu. Step 4. Select 2 and verify that Year, Month, and Time update as well as Long. & Lat. Step 5. Verify that a number of satellites are present. Step 6. Return to main menu by selection 0. Step 7. After all testing procedures have been performed, and all of the above tests pass, at the # prompt type shutdown –f. This will reboot the WLS and make it ready for the GCS to download the operating software.
