Note: The IP address of the float-free DRU is "10.0.0.150".
2. Check that all radars are in standby mode and other antennas are not transmitting
any signal.
3. Connect the float-free DRU to the PC and power (24 VDC), referring the following
figure.
Note: The float-free DRU cable may be different, depending on the time of man-
ufacture. Therefore, wire colors that connect to the #3 and #4 pins in the VR-
7022F depend on the cable specifications.

4. Turn the DCU on to supply the power to the float-free DRU.
5. Wait approx. 20 minutes until the float-free DRU starts up.
6. Activate the command prompt on the PC.
7. Enter "ping 10.0.0.150" on the command prompt.
8. Check the test result.
When the response from the float-free DRU is received successfully and there is
no package lost, go to the next step. If the response is not received or some pack-
ages are lost, check the connection and that the power is supplied to the float-free
DRU, then retry the ping test. If the failure is not rectified, there is a problem in the
LAN cable. Replace the LAN cable between the PC and junction box.
9. Enter "ping -l 45000 -n 40 -w 100 10.0.0.150" on the command prompt.
This commands the PC to request 40 packages of 45 KB and simulates high data
load.
10. Check the test result.
When the response from the float-free DRU is received successfully and there is
no package lost, go to the next step. If three packages or more are lost, there may
be connection error. Check the connection and retry the ping test.
11. Turn on either one of the radio equipment and start transmitting (ex. S-band ra-
dar).
12. Enter "ping -l 45000 -n 40 -w 100 10.0.0.150" on the command prompt.
13. Check the test result.
When the response from the float-free DRU is received successfully and there is
no package lost, the float-free DRU is not interfered with the other equipment. If
the response is not received or some packages are lost, the equipment turned on
at step 11 is causing the communication error. Change the installation location
and retry the ping test.
