3. Reboot the Sonar Firmware by double-clicking on the Sonar icon in the main Sonar Remote
Desktop Screen, as shown in
FIGURE 8-15, designated by green arrow.
4. Now, plug in the devices into COM 1 and COM 2. Which device is connected to which COM port
does not matter, as long as their respective ports and baud rates are set in Sonar.
5. Click on Misc. at the top of the Sonar screen, as shown in
FIGURE 8-16, then Serial Port
Information.
6. Check COM1 and set the correct baud rate for that device using the dropdown menu shown in
blue, as shown in
FIGURE 8-16. When the correct baud rate is set, the State should say OK, and
Errors should not be increasing, as shown in
FIGURE 8-16, circled in green. The correct data string
should also be scrolling in the lower part of the window, as shown in
FIGURE 8-16, green arrow.
7. Now Check COM2 and set the correct baud rate for the other device as done before in Step 6.
8. Now click on File > Show Status in the sonar window, as shown circled in red in
FIGURE 8-17.
9. On the right-hand side of the window, click on the Config bullet under the Update button and
then on the dropdown menu named Config Item, as shown in F
IGURE 8-18.
10. Select Serial from the dropdown menu (green arrow), then click on the Update button (blue
arrow) several times, as shown in F
IGURE 8-18.
11. Check to make sure sensors' usage percentages are well below 80%, as shown in
FIGURE 8-20,
circled in purple. If they are not, increase the sensor’s baud rate. Change baud rate under Serial
Port Information as done in steps 6 and 7. Check Status again. Otherwise, sonar will report errors.
