• | The vessel is berthed or at sea. |
• | You have a vacant interface port on your Processor Unit. |
• | You are familiar with NMEA and other relevant datagram formats. |
• | You know how to set up the parameters for serial and local area network (LAN) communication. |
• | The systems are all connected to a common synchronization system. |
• | One of the acoustic systems is set up as "master", and controls the transmissions on the other systems. |
1 | Connect the synchronisation cable from the remote system to an available communication port on your Processor Unit. This is described in the Cable layout and interconnections chapter.

2 | Open the Setup menu. |
3 | On the Setup menu, select Install.![]() Observe that the Install submenu opens.
|
4 | Select Synchronization Port to open the dialog box.![]() |
5 | Choose which serial port you have used to connect the external synchronization system. This is the interface port currently used to transmit or receive synchronization signals. It must be a serial port. Since the synchronization function only use the Request To Send (RTS) and Clear To Send (CTS) signals, you can use a serial port that is already used for other purposes. For the same reason, you do not need to define any baud rate.

6 | Select OK to save the chosen settings and close the dialog box. |
7 | Open the Setup menu. |
8 | Select Synchronization.![]() The purpose of the Synchronization dialog box is to set up the MS70 to operate alone, or as a master or slave in a synchronized system. Synchronization is required in order to avoid interference if the MS70 is used simultaneously with other hydroacoustic instruments within the same frequency range.

10 | Select Synchronization Delay. This delay parameter is used differently depending on the chosen synchronization mode.
