• | 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. |
• | Stand-alone The Synchronization Delay setting is not applicable when synchronization is switched off.
|
• | Master In Master mode, the ME70 system waits for the delay time after the external trigger signal has been sent to the slaves before transmitting the ping. This is often referred to as a pre-trigger.
Note
This delay will only work when the synchronization is set up using a serial port.
|
• | Slave In Slave mode, the ME70 system waits for the delay time after the external trigger signal has arrived before transmitting the ping. This is often referred to as a post-trigger.
|
• | Stand-alone Synchronization is turned off.This synchronization mode is used if the ME70 system is working by itself and with no synchronization required. This is the default setting. The ME70 system operates using its internal ping interval parameters, independent of any trigger signals arriving at the synchronization
port.
The Synchronization Delay setting is not applicable when synchronization is switched off.
|
• | Master Master mode is used if the ME70 system is going to act as the controlling unit in a synchronized system. The peripheral hydroacoustic system(s) are only permitted to transmit when enabled by the ME70 system. When Master mode is selected, the ME70 system will run using its internal ping interval parameters and send trigger signals to the peripheral system(s). For "master" operation, a remote hydroacoustic system (sonar, echo sounder) is connected. This remote system must be set up in "slave" mode.
|
• | Slave The Slave mode is used if the ME70 system shall transmit only when permitted by a peripheral system. When the Slave mode is selected, the ME70 system will not transmit ("ping") unless an external trigger appears on the chosen synchronization port. The peripheral system may be any other hydroacoustic product (for example an echo sounder or sonar), or even a dedicated synchronization
system. For "slave" operation, a remote system (for example K-Sync or Simrad TU40) must be available to provide trigger pulses.
