Turning on the entire FX80 system for the first time
In order to use the FX80, you must first turn it on. You must first power up the Bridge Control Unit, and then the Processor Unit. After this you can start the FX80 program. If you have a Sonar Head connected to your FX80 system, it is usually started once the Communication Hub is online and operational.
Prerequisites
•  The FX80 has been set up with its hardware units connected as specified in the relevant FX80 end-user documentation.
•  The Bridge Control Unit is connected to the Communication Hub with the test cable.
•  The Communication Hub is connected to the DFS75 Sonar Head.
•  The Communication Hub is connected to the camera and the lamp with the Y-split cable.
Context
The Bridge Control Unit provides all the interface and power supply functionality for the Simrad FX80 system.

Procedure
Important
When turning on the FX80 for the first time, use the test cable. After you have made sure the system works with the test cable, repeat this power-up procedure using the third-wire cable.
1 Power up the Bridge Control Unit.
Observe that the DSL Link button light briefly turns on, then turns off.
Note
There are two power switches on the Bridge Control Unit, one on the front panel and one on the rear panel. Both switches must be set to “On”. During normal operation, you only need to use the front mounted switch (E) to power on (and off) the unit.
2 Turn on the display.
If required, refer to the instructions provided by the display manufacturer.
3 Turn on the Processor Unit.
Wait while the operating system loads.
4 Double-click the FX80 icon on the Processor Unit desktop to start the program.
Note
The FX80 program is not automatically started when the Processor Unit is turned on.
5 Once the program has started, observe that the presentation fills the entire screen.
The program starts up using the same settings as the last time you used it. If these settings are acceptable, continue operation. If you wish to alter any of the settings, see the relevant procedures.
6 Press HV Start (D) on the Bridge Control Unit.
Observe that the HV On light turns on. Wait for the Link Status light (B) to flash slowly, then quickly, then turn solid. When lit continuously, the Link Status light indicates that a communication link is established between the Communication Hub and the Bridge Control Unit.
7 Make sure that the blue indicator light on the Communication Hub is lit.
This light indicates that the high voltage from the Bridge Control Unit is present.
8 At the bottom of the FX80 presentation, verify that the camera is connected.
The current connection speed between the Bridge Control Unit and the Communication Hub is also shown. The speed depends on the length and quality of the third-wire cable.

Note
Aux 1 is the default label for this button. If you create a custom button label (SetupSystem SetupAux 1Button Label), then this button will have a different name.
b Double-click the DATSS icon on the Processor Unit desktop to start the program.
Note
The DATSS program is not automatically started when the Processor Unit is turned on.
If you use only one display, the trawl sonar presentation will now fill the screen. Switch between the FX80 and DATSS software in the Windows taskbar. If you have two displays, use the operating system functionality to move one of the programs to the other display.
c Click the Setup tab on the right side of the presentation.
Observe that the Setup menu opens.
d Click the Connect Sonar button.

Observe that the Connect Sonar dialog box opens.
e In the Devices list, select the port your Sonar Head is connected to.
Tip
If the expected port does not appear at first, click the Reset button to refresh the list of available ports.
f Check the Enable for Head Control box.
g Click the Detect Heads button.
A progress bar will be shown as the software establishes communication with the Sonar Head. When each Sonar Head has been detected, it will appear in the Devices list with details shown at the bottom of the dialog box.
h Click Apply to save any changes you have made.
i Click OK to close the Connect Sonar dialog box.
j Click System.
Image
The System button is always available in the Main menu at the bottom-right corner of the display presentation, unless you have chosen to hide the menu system. Observe that a submenu opens when you click the button.
k Select Run.
Wait for the Sonar Head to start.
Caution
Do not connect or disconnect any cables while the system is turned on. Do not leave power on to ports that aren’t connected to anything (even if there are dummy plugs installed).
