K-Sync interface to generic RS-232 synchronization input
For transmission synchronization purposes, the K-Sync will interface a generic RS-232 serial line communication port using the CTS (Clear To Send) and RTS (Request To Send) signals.
The synchronized product is connected to the IO Module inside the K-Sync Synchronizing Unit. Each IO Module in the K-Sync Synchronizing Unit provides six connectors and a configuration board for physical adjustments of the communication parameters.
Pin number Signal Signal description
1 Trigger Out This signal is transmitted to the system that needs to be synchronized. Trigger Out allows the system to transmit ("ping").
2 Ground Mandatory! This ground is connected to pin 5 inside the IO Module.
3 RTT Ready to Transmit: Ready to Transmit (RTT) is a return signal from the hydroacoustic system that is synchronized. The Ready to Transmit (RTT) signal means that the hydroacoustic system is ready for the next trigger.
4 Trigger In This signal is received from the system that needs to be synchronized. Trigger In is "active" while the system is transmitting.
5 Ground Mandatory! This ground is connected to pin 2 inside the IO Module.

Unless otherwise specified, this cable must be provided by the installation shipyard.
Minimum cable requirements
•  Conductors2 x 5 x 0.5 mm2
•  ScreenOverall braided
•  Voltage: 60 V
•  Maximum outer diameterDefined by the plugs and/or the cable gland
If you need to install a very long cable, increase the cross section.
