For a more robust communications protocol, the CXPS supports external controllers, such
as Crestron or AMX devices. Black Diamond Video has developed a special control
protocol which will enable most control applications. This protocol is enabled and disabled
with the command
EXTCTL <ON|OFF>
.
Once the protocol is enabled, all commands sent to the CXPS are echoed back to the
controller. The feedback from the CXPS is structured as follows:
STX(0x02) [command in upper case] [result] ETX(0x03)
E X A M P L E
With a DVI signal connected to input 3, you want to know if input 3 has a valid signal.You
use the
INSTATUS 3
command. As a valid signal is present, the result is
1
.
The ascii code issued from the controller for this example is:
0x69 0x6E 0x73 0x74 0x61 0x74 0x75 0x73 0x20 0x33 0x0A 0x0D
The CXPS echoes back the command in upper case together with the result, and bracketed
by the start and end transmission codes:
0x02 0x49 0x4E 0x53 0x54 0x41 0x54 0x55 0x53 0x20 0x33 0x20
0x31 0x0A 0x0D 0x03
ZOOM <window #> <action>
<speed> This type of pan and zoom is meant for use with a
programmable external control device.
Run the command in background mode. This
command will run until it reaches the limit or
receives a stop instruction.
<window #> is the number (1-36) of the output
channel connected to the window you want to
control.
<action>
is one of the following:
zi- zoom in (size up), zo- zoom out (size down),
pu- pan up, pd- pan down, pl- pan left, pr- pan
right, STOP.
<speed>
is a value from 1 - 10 and sets the speed
of the action.
NOTE: Using the ZOOM command’s zoom
controls when under windowing mode will size the
window up or down. Use the continuous WINPOS
command to zoom within a selected window.
