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 external device is connected to the IO Module inside the K-Sync Synchronizing Unit.
The pin configuration on the K-Sync IO Module follows:
Pin no. Signal Description
1 TRIG OUT Trigger out – Signal to external device enabling it to transmit
2 GROUND Mandatory – connected to pin 5 inside the module
3 RTT Ready to transmit – Input from external device when it is ready for the next trigger pulse
4 TRIG IN Trigger in – Input from external device, active while the device is transmitting
5 GROUND Mandatory – connected to pin 2 inside the module
6 Not used

Each IO Module in the K-Sync Synchronizing Unit provides six connectors and a configuration board for physical adjustments of the communication parameters.
A Connectors 1 through 6 as indicated by the arrows.
Note that each of the two connector elements can be pulled out of the IO Module for easy access.
B Configuration board
Unless otherwise specified, this cable must be provided by the installation shipyard.
Minimum cable requirements
•  Conductors2 x 5 x 0.5 mm²
