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.
