Note: Data is transmitted even in the absence of video and audio signals.
The TP-578H treats RS-232 data in either of the following manners:
 Active—The data are treated as Kramer Protocol 3000 commands and are
processed by the microcontroller of the TP-578H
 Passive—The data is treated as raw data and is transmitted over the DGKat
link with no processing
To select the active or passive data mode:
 Press the K-Link mode button to toggle between the active and passive data
modes.
When the K-Link LED on the front panel lights green, the device is in the
active mode. When the K-Link LED lights red, the device is in the passive
mode.
