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 Synchronization
Unit. Each IO Module in the K-Sync Synchronization Unit provides six connectors and a
configuration board for physical adjustments of the communication parameters.
