12 The VP-773 RS-232 Communication Protocol
The Kramer Protocol lets you control the VP-773 from any standard terminal
software (for example, the Windows
®
HyperTerminal Application).
12.1 Using the Communication Protocol
There are three different methods to control the VP-773 RS-232 or the Ethernet:

Protocol commands (via protocol 3000 or Legacy Protocol) mimicking the
OSD, see Section
12.2

The button functions mimicking the remote controller buttons (as well as the
front panel buttons), see Section
12.3

Protocol 3000 common commands, see Section
12.4
All three tables together include all the protocol commands, but they
are not identical and do not always include the same information.
Some of the data may appear in one or two of the tables but not in the
third table and vice versa.
The protocol 3000 communications protocol uses a data rate of 115200 baud, with
no parity, 8 data bits, and 1 stop bit.
The Legacy communication protocol uses a data rate of 9600 baud, with no parity,
8 data bits and 1 stop bit. CTS mode and XON/XOFF are set to Off.
Note that if the Protocol is set to Legacy (via the Miscellaneous menu,
see
Section 6.8 ), some PC applications (for example, K-Upload), as
well as the Web pages may not function properly.
