SECTION 1: OverviewThe Harbor Acceptance Test (HAT) is performed after the vessel is floated and confirms correct installation and functionality of the FarSounder hardware. There is no need for a sea trial to confirm the system is function. However, separate from the HAT and commissioning, end user training is most effective when done at sea. These procedures test the installed functionality of a single sonar sensor node1 after the vessel is in water. For systems with multiple nodes, these procedures should be followed for each node.

Functionality tested with HAT include:

• TX transducer connection

• Booting/network connectivity of RX electronics

• Connectivity of Power Module control lines (Ping, Ctrl A, Ctrl B)

• RX transducer element operability

• Correct installation and configuration of the SonaSoft software

SECTION 2: Required Equipment for HAT• Installed Power Module

• Installed Transducer Module

• Installed Connection Cable

• SonaSoft software installed on a Windows 7 computer2

SECTION 3: ProceduresPART A: Confirm Power Module not in “Dry Dock Mode”

During the Customer Hardware Acceptance Test (CHAT), the Power Module must be set to “Dry Dock Mode” by turning the transmitter off (TX Off). After installation on the vessel, the Power Module should not be set for dry dock mode.

When powered on in dry dock mode, the red LED on the front panel of the Power Module labeled “TX Off” is illuminated. Older Power Modules without this feature cannot be set to dry dock mode. Dry dock mode can be turned off by following these procedures:

1 A sonar sensor node consists of a Power Module and a Transducer Module connected by a Sonar Connection Cable. FarSounder's navigation sonars are based around a single node (i.e. a sonar on the bow of the vessel). FarSounder's SPS systems are based around six or more nodes (i.e. one on the bow with others placed around the vessel to offer 360 degree coverage).

2 Note that this test calls for the standard SonaSoft software to be installed on the bridge computer. Note that each build of the software is specially configured for each Transducer Module. Do not use a SonaSoft that was built for a different Transducer Module.

For bulkhead mount Power Modules:

1. Make sure the unit is turned off and mains power is disconnected. Wait until all LEDs are off.

2. Open the front cover by loosening the four corner fasteners. Be careful when removing the cover panel as it is attached to the internal PCB via a ribbon connector. The ribbon connector plugs into the receptacle near the center of the PCB (see figure 2).

3. Find the “Dock Dock Mode” on/off toggle switch at the top right of PCB. Set the toggle to “off” (see figure 2).

4. Confirm that the Sonar Connection Cable is connected to the PCB as specified in the Operation Manual.

For rack-mount mount Power Modules:

1. Make sure the unit is turned off and mains power is disconnected. Wait until all LEDs are off.

2. Find the “TX On/Off” toggle switch on the front of the unit. Set the toggle to “off” (see figure 3).

3. Confirm that the Sonar Connection Cable is connected to the PCB as specified in the Operation Manual.

PART B: TX Transducer Connection Test

1. Ensure that the Power Module is still unplugged from AC power.

2. Unplug the coax from the BNC connector.

3. Using the capacitance meter functionality found on a standard multimeter,

measure the capacitance between the pin and the shield of the coax cable.

4. Value should read around 2.9nF if the connection is good. (The transmit transducer adds approximately 2.7nF to the capacitance of the transmission cable. The transmission cable has an approximate capacitance of .067nF per meter.)

5. Plug the coax back into the Power Module.

6. Close the Power Module's enclosure and connect mains power.

7. Turn on Power Module.

PART C: Booting/Network Connectivity Test

1. Ensure the computer's IP Address is on the 192.168.0.x subnet.

2. Set subnet mask of the computer to 255.255.255.0

3. Turn on the Power Module.

4. Wait about 15 seconds.

5. After Windows Network is established (this may take 10-90 seconds depending upon your computer), perform network pings:

◦ For a FarSounder-500:

▪ ping 192.168.0.2

▪ ping 192.168.0.3

◦ For a FarSounder-1000:

▪ ping 192.168.0.2

▪ ping 192.168.0.3

▪ ping 192.168.0.4

▪ ping 192.168.0.5

◦ For a FarSounder-SPS:

▪ ping all IPs from 192.168.0.2 through 192.168.0.25 (assuming 6 nodes. Each node has 4 IPs.)

Successful pings show that the unit has booted and firmware is loaded.

PART D: Confirm Computer Set Up

• Confirm that the bridge computer has the SonaSoft software installed. Contact service@farsounder.com for notification about any software updates which may be available for the sonar.

• Confirm that the ship's external navigation sensors are connected to the

bridge computer via NMEA 0183 and configured to produce the required messages:

◦ HDT or HDG (heading from compass, gyro preferred)

◦ ROT (rate of turn, gyro preferred)

◦ GLL, RMC or GGA (lat and lon from GPS)

◦ DBT or DPT (depth from echosounder)

◦ VTG, VHW or RMC (speed over ground)

• Start SonaSoft and confirm NMEA settings in the configuration manager3 are set correctly. If set correctly and the sensors are active, the Navigation Info View inside SonaSoft should display vessel speed, vessel heading, lat/lon and echosounder depth.

• Exit SonaSoft.

PART E: Power Module Control Line Test

1. Examine Power Module LEDs. Ctrl A and Ctrl B should be blinking A-A-B-B-A-A-B-B... This shows that the control line return and the two control lines are working properly.

2. Start the SonaSoft software.

3. After a few moments, the software should connect to the Transducer Module. A status message should pop up in the software stating that it is connecting. This connection process may take up to about 1 minute the first time the software connects after a Power Module power up.

4. Once connected, the unit should blink the Ping LED approximately once every 1-2 seconds. The states of Ctrl A/B LEDs will change during this period. Their states are not important. This shows that the ping control line is working properly.

PART F: RX Transducer Element Operability Test

1.With the SonaSoft software running, open the System Status window. This is an option from the Configuration Manager. A window showing the receiver array's channels should be shown. Each square represents an element in the array4.

3 The configuration manager is accessed from the gear icon at the top left of the screen.4 Note that it is normal manufacturing tolerance to have up to 2 channels not responding. This is

not a problem.

2.Select a central receiver channel by clicking one of the squares with the mouse. The receiver hydrophone time series should now be displayed to the left of the “checker board”. You should see a signal that is very loud at the left side of the signal display and tapers to almost 0 at the right end of the display. If the sonar processor mode is set to a long range (500 meters or more), the loud portion of the signal will be longer than if the sonar is set to a short range (200 meters or less). An example image of the status when set to long range is shown in figure 5.

PART G: Data Export

After completing the HAT, a data export may be performed with resulting export data files sent to FarSounder for review. It is recommended that the export be performed in both short and long range modes in order to include both transmit signals.

1. Set the sonar to a short range mode (200 meters or less).

2. Perform an “Export”. This option is a Configuration Manager menu option.

3. Set the sonar to a long range mode (500 meters or more).

4. Perform an “Export”. This option is a Configuration Manager menu option.

5. Send the two exported .zip files to FarSounder. For convenience, we offer a file transfer service on our website: http://www.farsounder.com/sales_and_support/service
