 “C” responses
A “C” response is sent as shown below when a control command is received:
[CR][LF]C:<Lvls>/<Dest>,<Src>[…[S<Salvo number>][L<Link number>]]:I<ID>[CR][LF]
* C responses are sent to all the terminals in the system.
* C response ON/OFF can be set in [Web-Based Control: Port Settings page.
Parameter
Setting range
Description
<Salvo number >
1-FFF
The number of crosspoints that are to be changed
simultaneously by Salvo settings.
A response if 3 crosspoints are to be changed
simultaneously: C:0/0,0...S2:IA
<Link number>
1-FFF
The number of crosspoints that are to be changed
simultaneously by Link settings.
A response if 2 crosspoints are to be changed
simultaneously: C:0/0,2...L1:IA
 “S” responses
An “S” response is sent as shown below when crosspoints are switched by a command.
[CR][LF]C:<Lvls>/<Dest>,<Src>[…[S<Salvo number>][L<Link number>]]:I<ID>[CR][LF]
* If a crosspoint is switched by an X or B command, its “S” response is sent to all the terminals in the
system. However, if any crosspoints are not switched (specifying the same crosspoint as the current
one), its “S” response is sent only to the terminal that sent the command.
* C responses are sent before S responses in some cases.
* A command is received from another terminal while a B or X command is processed, MFR units send “S”
response messages to the terminals, notifying only the latest crosspoint states.
* A crosspoint switch command is not performed if the relevant crosspoint is locked or inhibited to change.
* S response ON/OFF can be set in [Web-Based Control: Port Settings page.
