VP-772 - The VP-772 RS-232 Communication Protocol
11
The VP-772 RS-232 Communication
Protocol
The Kramer Protocol lets you control the
VP-772
from any standard terminal
software (for example, the Windows
®
HyperTerminal Application).
11.1
Using the Communication Protocol
There are three different methods to control the
VP-772
RS-232 or the Ethernet:
Protocol commands mimicking the OSD, see
Section
11.2
The button functions mimicking the remote controller buttons (as well as the
front panel buttons), see
Section
11.3
Protocol 3000 common commands, see
Section
11.4
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.
11.2
Communication Protocol: Mimicking OSD
The audio/video protocol commands define all the function numbers, their valid
parameters can be used with protocol 3000.
11.2.1
Using the Communication Protocol with Protocol 3000
(the “Y” Command)
Set
Command
:
Type in: “Y Control_Type=0,Function,Param”
Reply: “~id=01Y Control_Type=0,Function,Param OK”
Set command example: set HDCP mode for input 1 (113) to “On”
