Protocol 3000 Commands

Function Description
#
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-
Set auto switching
TIMEOUT
timeout.
AV-SW-
Get auto switching
TIMEOUT?
timeout.
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.
DISPLAY?
Get output HPD status.

edid_io
(usually output)
0 – Input
1 – Output
2 – Default EDID
3 – Custom EDID

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)
– Number that
out_index
indicates the specific output:
1 – Output 1
2 – Output 2
3 – Output 3
4 – Output 4
– HPD status according to
status
signal validation
0 – Signal or sink is not valid

2 – Sink and EDID is valid
Example
#<CR>
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
>
Get the Disable 5V on video
output if no input signal
detected timeout:
#AV-SW-TIMEOUT?4<CR>
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>
Get the output HPD status of
Output 1:
#DISPLAY?1<CR>
