8.4.1. Switch 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 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
achieve multiple switches executed together, see
#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. Switch an Input to All Outputs
Switch input <in>
Command and Response
ȩ {<in>@O}
Ȩ (I<in2>•ALL)CrLf
Example
ȩ {2@O}
Ȩ (I02 ALL)
8.4.3. Batch Switch 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! The delay timeout applies for the receiving time of characters. Please note that if LAN
connection is used then the network may cause additional delays. This could result that batch switching
does not occur. Below example shows a command that resulted batch switching:
