limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable protection against harmful inter-
ference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
This is a Class A product. In a domestic environment,
this product may cause radio interference, in which case,
the user may be required to take appropriate measures.

* In previous Navigator GUI versions this was the System 3rd Party Devices tab.
Adding VP-8ip To The Peripheral Devices* Tab
In order to utilize all the features of the VP‑8iP Digital Audio
Processor the device must be added to the System Peripheral
Devices tab in the Wheatstone WheatNet-IP Navigator program
(aka the Navigator GUI). This sheet shows you the basics of that
procedure. Refer to the WheatNet‑IP BLADE3 Audio Over IP
Network Technical Manual for additional details.
You will need to know the IP address of the device being
added, so you will want to nd that out before you start.
Launch the Navigator GUI and make sure that System 0 is
selected in the System pane. You will see something like this:
Now select the Peripheral Devices tab.
Click the Add button to bring up the Add Peripheral
Device dialog:
Type in a convenient Name and insert the IP Address
of the device being added. Leave the TCP Port at the
default setting of 60021. From the Host BLADE drop
down select the BLADE that you want to associate the
Peripheral device with. Click Ok.
This completes the process of adding the device to
the Peripheral Devices tab. The added device should
show up in the System pane under the BLADE you
added it to. If it does not show up, or if it shows up but
has a yellow question mark on it, then there is either a
network issue that needs attention, or the device is not
connected to the network at all, or one or more steps have been omitted or done incorrectly
in the conguration process.
