14 WP-577VH - Principles of Operation
6.4 K-Link Active and Passive Local RS-232 Data Modes
The Local RS-232 port can be set to either active or passive mode.
1. In active mode, the data are treated as Protocol 3000 commands and these
provide control of the WP-577VH .
Figure 5 illustrates a sample setup when using the active mode from the local
RS-232 port.

2. In passive mode, the data are treated as raw data and are transmitted over
the DGKat link with no local processing. This data can be used to either
communicate with remote K-link devices (by sending Protocol 3000
commands and by setting the remote device to active mode), or it can be
used to control an external device connected to the RS-232 port of a remote
device (either a K-Link device set to passive mode or a legacy device, for
example, the TP-574 ).
