8.4.1. Switching an Input to an Output
Switching an input
<in>
to output <out>. Following commands with A, V, AV parameter value can take effect
in multiple layers, according to their parameters. Depending on 'A' or 'V' it can change only the Audio or only
the Video layer; or 'AV' changes both.
Command and Response
ȩ {<in>@<out>•<layer>}
Ȩ (O<out2>•I<in2>•<layer>)CrLf
Parameters
Identifier
Parameter description
<layer>
Signal type of the layer
<out>
Output port
<in>
Input port
INFO:
The
<layer>
parameter usually can be skipped for legacy purposes. In this case, the devices change
all (Video & Audio) layers, but using status commands, it displays information about only the Video layer.
Please use the AV option when available.
Example 1
ȩ {2@1 AV}
Ȩ (O01 I02)
I2 audio and I2 video input ports are switched to O1 output port.
Example 2
ȩ {0@1}
Ȩ (O01 I00)
ATTENTION!
The response of this command does not show if the output is muted. To check the mute
status, a separate query has to be used like {VC}. See the
section. To achieve multiple switches executed together, see the
#crosspoint
#switch
Parameter values
A: audio layer
V: video layer
AV: audio & video layer
O1-O4 (or O8)
I1-I8
0: Using the '0' (zero) value, the input will be
disconnected and no signal will appear on the output

8.4.2. Switching an Input to All Outputs
Switch input

Command and Response
ȩ {<in>@O}

Example
ȩ {2@O}
Ȩ (I02 ALL)
8.4.3. Batch Switching Outputs
The device is capable of switching multiple outputs exactly at the same time. To do this, the normal switch
commands have to be used. If the switch commands arrive at the device with less than 10 milliseconds
delay, the commands are collected and changes the output connections together.
Required circumstances:
▪
Switch commands have this format: {<in>@<out>}{<in>@<out>}
▪
The delay between two '}' characters must be below 10 milliseconds
No other command or junk character is allowed between switch commands
▪
▪
Affected outputs must not be locked
If any of the above circumstances fail, then the commands will be processed separately and the output
connections will change one by one.
ATTENTION!
connection is used then the network may cause additional delays. This could result in batch switching
failing to occur. The example below shows a command that resulted in batch switching:
