3.8 Operator Controls and Indicators
The TIU includes a D/C–OFF–A/C switch and a power/transmit indicator. These
items are located on a side panel as shown in Figure 3-4 on page 3-7. The switch
switches either DC or AC power to the TIU or turns it off. The power/transmit
indicator illuminates when the TIU is first turned on and then flashes when the
Sonar Head Unit is operating and the transducers are transmitting. The flash rate is
the same as the ping rate of the transducers.
3.9 Activating the System and Performing the
Predeployment Tests
The HydroChart 3500 Sonar System should be activated and a few predeployment
tests should be performed before starting an actual survey. Before activating the
system, however, SonarPro should be installed on the PC. For instructions on how
to install and run SonarPro, refer to
the
"SonarPro User Manual."
To activate the system and perform the predeployment test:
1.
Verify that the Sonar Head Unit has been properly set up and the system
components connected.
2. Verify that the deck cable is connected to the TIU and to the Sonar Head Unit.
3.
Turn on the navigation system and let it acquire its location.
4. Turn on the PC and wait for the Windows desktop to appear.
5. Turn on the TIU.
The power/transmit indicator should illuminate, and then after approximately
45 seconds, it should begin flashing.
NOTE Should it be required to change the IP address, edit the startup.ini
file or update the software of the Sonar Head Unit, refer to APPENDIX B:
“Configuring and Updating the Sonar Head Unit.” The factory default IP
address for the Sonar Head Unit is 192.168.0.81. The PC IP address should be set to
192.168.0.82.
CAUTION Serious damage to the Sonar Head Unit electronics may occur
if the Sonar Head Unit is operated on deck for extended periods. Do not
allow the Sonar Head Unit to operate for longer that 30 minutes at a time
and allow at least a 15-minute cool down between operations. In addition, in high
temperature climates, protect the Sonar Head Unit from direct exposure to the sun
prior to and during operation.
