DPP Port (applicable models)
The product is equipped with DPP port enabling connectivity to

The filtered USB function (DPP) enables to control which USB devices
will be operative when connected to product.
For more details on configuration options, please refer to the "DPP
Configuration Manual".
Summary of rules that apply to DPP switching:
It is assumed that a "connected channel" is when:
1. Product is powered ON
2. The USB device connected to product console is qualified
and ready for use, as indicated by the DPP status LED
illuminating steady green.
3. The channel DPP port on product is connected via USB cable
to a USB port on computer.

When the USB device connected to the DPP console port is
qualified, the DPP status LED on the front panel would
illuminate steady green.

Section 4 - Operation
port, the DPP LED will flash green and USB device will
be inoperable. In such case the USB device must be
replaced with a qualified device.
o When connecting a USB device to the product's DPP
port that is undetectable for any reason (e.g. failed
device, non-standard device etc.), the DPP LED will
not illuminate at all and USB device will be
inoperable. In such case the USB device must be
replaced with a qualified device.

Since channel #1 is the default active channel after power up
and in case only some of the channels operate with a USB
device, it is recommended to make sure computer #1 is
connected to USB device.

Once the user switches channels, for example to channel #3,
DPP functionality will move to computer #3 and be indicated
by channel #3 DPP LED turning steady green.

In case user switches to a channel that is not connected to a
USB device, the previous USB connection will be terminated
and no new connection will be established.

In case "Freeze DPP" slider was moved to activate DPP
function for computer #1, for example, switching to a
different channel would keep DPP function locked to channel
#1. To release "Freeze DPP" function from channel #1, the
user will need to move the "Freeze DPP" slider again to its
original position. The release will be indicated by the channel
#1 DPP LED being turned off.

In case Restore-to-Default was performed while "Freeze
DPP" slider was activated on a specific channel, after boot up
this function will be locked to computer #1.
