Format
Example
Command {AS_V<out>=<state>;
<mode>;<no_signal>}
→ {as_v1=E;K;B}
Response (AS_V<out>=<state>;
<mode>;<no_signal>)CrLf
← (AS_V1=E;K;B)CrLf
Legend:

on page
Explanation:
The Autoselect mode is enabled in first detect mode, and if there is no
incoming signal at all, the crosspoint is not changed (blank screen).
7.3.10. Query audio Autoselect mode

The autoselect mode of audio output can be queried.
Format
Example
Command {AS_A<out>=?}
→ {as_a1=?}
Response (AS_A<out>=<state>;
<mode>;<no_signal>)CrLf
← (AS_A1=E;K;B)CrLf
Legend:
<out>:
The output port number (1). See more details about port
on page
<state>:
E = Autoselect is enabled; D = Autoselect is disabled
<mode>:
P = Priority detect; K = First detect; L = Last detect; S = Static
<no_signal>:
B = Blank; M = Mute output
Explanation:
The device reports that the Autoselect mode is enabled in first detect mode,
and if there is no incoming signal at all, the crosspoint is not changed.

Description:
The settings of video input priority can be queried as follows.
Format
Example
Command {PRIO_V<out>=?}
→ {prio_v1=?}
Response (PRIO_V<out>=<in1_prio>;
<in2_prio>;..;<in
n
_prio>)CrLf
← (PRIO_V1=1;0;2;3;4;31)CrLf
Legend:
<out>:
The output port number (1).
<in
1_prio>…<in
n
_prio>:
Input ports’ priority number. See more details
about port numbering in section
on page
Explanation:
P2 has the highest priority (0), P1 has the second highest priority number
(1). P6 has priority 31 which is the lowest possible setting; it means P6 is disabled from the
priority list and cannot be selected.
