Once the user presses again the DPP freeze push-button, freeze
mode will be deactivated and DPP will switch to same channel as
KM Switch selected channel #3 in this case. DPP status LED will
return to steady green as before.
If the user switches now the KM Switch to channel #2 the DPP will
automatically enter freeze mode as indicated by the blinking green
DPP status LED.
If the user will now switch the KM Switch to channel #1 DPP will
remain in freeze mode on channel #3 as before.

The set of rules that applies to the DPP switching are:
Note: It is assumed here that connected channel is channel that
connected to the computer with DPP USB cable and that the
connected computer is running (after boot completion).
1. The DPP will follow the KVM channel selection unless:
User has selected DPP freeze mode; or
•
KVM was switched to unconnected/unpowered
•
channel and then the device will enter DPP
freeze mode automatically.
2. DPP would not release from freeze mode when KVM
selected channel is unconnected.
3. Once released from freeze mode the DPP will follow the
KVM selected channel.
4. If connected device is unqualified or not recognized then
no switching will be possible. DPP is deactivated
(indicated by DPP mode LED illuminating in steady red
