5.7.4.5 Request Crosspoint Status (S?{Lvl})
This is the command for querying the switching status of the device or of a level
>@<sp> S?{Lvl}<CR>
The "{""}" are indicating the level information as optional.
As described in chapter 5.7.1 two scenarios are to be distinguished:
5.7.4.5.1 Individual Switching Mode with Individual Switch Level Assignment Enabled
(i) The response to the command requesting the switching status of the device
>@<sp> S?<CR>
initiates the device answer
S:00,<Src0> e.g. S:00,1
S:10,<Src1> S:10,0
(…) (…)
S:F0,<SrcF> S:F0,0
>_
with:
<Src0>…<SrcF> being either 0 for input port "In A" or 1 for input port "In B".
(ii) The response to the command requesting the switching status of a level
>@<sp> S?<Lvl><CR>
initiates the device answer
S:<Lvl>0,<Src> e.g. S:00,1
>_
with:
<Lvl> being the number (minus 1) of the addressed switch module and
<Src> being either 0 for input port "In A" or 1 for input port "In B".
5.7.4.5.2 Individual Switch Level Assignment Disabled
(i) The response to the command requesting the switching status of the device
>@<sp> S?<CR>
