Example
#
Protocol handshaking.
Validates the
Protocol 3000
connection and gets the
machine number.
Step-in master products
use this command to
identify the availability
of a device.

AV-SW-
TIMEOUT
Set auto switching
timeout.
COMMAND
#AV-SW-TIMEOUTswitching_mode,time_out<CR>
FEEDBACK
~nn@AV-SW-TIMEOUTswitching_mode,time_out<CR><LF>
switching_mode – Switching
mode
0 – Video signal lost
1 – New video signal detected
2 – Audio signal lost
4 – Disable 5V on video output if
no input signal detected
5 – Video cable unplugged
6 – Audio cable unplugged
7 – Video signal lost for signal
routed as a result of a manual
override action
time_out – Timeout in seconds
0 - 60000
Set the auto switching
timeout to 5 seconds in the
event of 5V disable when no
input signal is detected:
#AV-SW-TIMEOUT4,5<CR

AV-SW-
TIMEOUT?
Get auto switching
timeout.
COMMAND
#AV-SW-TIMEOUT?switching_mode<CR>
FEEDBACK
~nn@AV-SW-TIMEOUTswitching_mode,time_out<CR><LF>
switching_mode – Switching
mode
0 – Video signal lost
1 – New video signal detected
2 – Audio signal lost
4 – Disable 5V on video output if
no input signal detected
5 – Video cable unplugged
6 – Audio cable unplugged
7 – Video signal lost for signal
routed as a result of a manual
override action
time_out – Timeout in seconds
0 - 60000
Get the Disable 5V on video
output if no input signal
detected timeout:
#AV-SW-TIMEOUT?4<CR>
CPEDID
Copy EDID data from
the output to the input
EEPROM.
Destination bitmap
size depends on device
properties (for 64 inputs
it is a 64-bit word).
Example: bitmap
0x0013 means inputs
1,2 and 5 are loaded
with the new EDID.
In certain products
Safe_mode is an
optional parameter.
See the HELP
command for its
availability.
COMMAND
#CPEDIDedid_io,src_id,edid_io,dest_bitmap<CR>
or
#CPEDIDedid_io,src_id,edid_io,dest_bitmap,safe_mode<CR>
FEEDBACK
~nn@CPEDIDedid_io,src_id,edid_io,dest_bitmap<CR><LF>
~nn@CPEDIDedid_io,src_id,edid_io,dest_bitmap,safe_mode<
CR><LF>
edid_io – EDID source type
(usually output)
0 – Input
1 – Output
2 – Default EDID
3 – Custom EDID
src_id – Number of chosen
source stage
0 – Default EDID source
1 – Output 1
2 – Output 2
3 – Output 3
4 – Output 4
edid_io – EDID destination type
(usually input)
0 – Input
dest_bitmap – Bitmap
representing destination IDs.
Format: XXXX…X, where X is hex
digit. The binary form of every hex
digit represents corresponding
destinations.
0 – indicates that EDID data is not
copied to this destination.
1 – indicates that EDID data is
copied to this destination.
safe_mode – Safe mode
0 – device accepts the EDID as is
without trying to adjust
1 – device tries to adjust the EDID
(default value if no parameter
is sent)
Copy the EDID data from the
Output 1 (EDID source) to
the Input:
#CPEDID1,1,0,0x1<CR>
Copy the EDID data from the
default EDID source to the
Input:
#CPEDID2,0,0,0x1<CR>
DISPLAY?
Get output HPD status.
COMMAND
#DISPLAY?out_index<CR>
FEEDBACK
~nn@DISPLAYout_index,status<CR><LF>
out_index – Number that
indicates the specific output:
1 – Output 1
2 – Output 2
3 – Output 3
4 – Output 4
status – HPD status according to
signal validation
0 – Signal or sink is not valid
1 – Signal or sink is valid
2 – Sink and EDID is valid
Get the output HPD status of
Output 1:
#DISPLAY?1<CR>
