7.1 Initial Power-up and Site Survey Test
1. On the IDU move the power switch to the ON position. After the units boots and the GPS initializes
(< 2 minutes) the status LEDs on the IDU should be as follows:
a. Power = Green
b. Status = Amber (Status can be Green with software version A012001)
c. Signal=Green
d. GPS=Green
2. Turn on the laptop computer and install the Iridium Pilot Land Station Accessory CD.
3. The PC should display the CD directory. Select the Site Survey Tool (SST) and double click to start the tool.
(note the tool assumes the default IP address if the address has been changed select the settings menu from
the Task bar and input the alternate IP address).
4. At this time make sure the any navigation and communication systems are on and active.
5. Click on the "Start" button on the SST application to begin the test. The tool scans ~ 2.6 channels per
second requiring 97 seconds to complete a single scan. Several scans are useful in assessing the local noise
environment and to detect down link information from the Iridium constellation. Note the screen will be
updating to provide feedback the program is executing normally.
6. This test validates that you have placed the Iridium equipment in a good location. See Appendix G for more
information on the SST.
8. Installing the System
Now that a suitable location for the ODU has been verified the equipment can be permanently installed for
operation. The permanent installation is comprised of 7 steps.
1. Route the ODU/IDU interface cable.
2. Connect and mount the ODU and note that the ground lug orientation will be used in software as "Aft" or
rear orientation.
3. Connect the ground cable from the ODU to a ground connection
4. Mount the IDU.
5. Connect the ground to the IDU, then the ODU/IDU interface cable and then the power connector
6. Connect the telephones and computer network to the IDU.
7. Test and verify the installation.
Routing the ODU/IDU Interface Cable
The interface cable has a waterproof circular connector that connects to the ODU and a shielded RJ-45
connector that connects to the IDU. Since the IDU side is much smaller it makes sense to pull the cable from
the ODU towards the IDU. Once the ODU site is known, an IDU location must be selected that is within the
distance of the ODU/IDU cable, accounting for the path thru the cable chase. Drill any required access holes in
order to route the cable to the interior of the location. The cable should be pulled by the RJ-45 connector. Use
care and install a pull string that attaches to the cable jacket and does not place stress on the connector. Use
electrical tape to protect the RJ-45 during the pull operation. Leave just enough service loop at the ODU and
store any excess cable in the cable chase or near the IDU.
Note: The ODU/IDU cable must be grounded prior to installing on the ODU or the IDU. Connect a wire strap/
electrical clip from the metal RJ-45 housing to a ground connection (not an existing electrical system ground).
Connect the cable to the ODU first. After the ground cable has been installed on the ODU you may then remove
the electrical clips.
