Model 5205
Mic/Line to Dante Interface
Windows® operating system. Changes
made using the application will be dis-
played in real-time on the Model 5205’s
LED indicators. Changes made to the
preamplifier gain and P48 on/off status
using the Model 5205’s local pushbutton
switches will be displayed in STcontroller.
Button Lock-Out
There may be situations where it’s desir-
able for the preamplifier gain and P48
phantom power on/off configurations to
be maintained without the risk that an un-
authorized user will press one of the but-
tons and cause an unwanted change
to be made. A button lock-out function is
included to minimize the chance that this
will occur. Using the function is very sim
-
ple: simultaneously press and hold both
P48 buttons for approximately 2 seconds
until the two P48 LEDs flash. This will indi-
cate that a change has been made to the
button lock-out status.
When the button lock-out function is en-
abled the six pushbuttons will no longer
allow any local preamplifier gain or P48
configuration changes to be made. During
operation, if the buttons are “locked” press-
ing a P48, gain up, or gain down button will
cause both P48 LEDs to flash three times
but no change will occur. Only by chang-
ing the status of the lock-out function, by
pressing and holding both P48 buttons,
will local changes to the gain or P48 on/off
status be allowed.
Remote monitoring and control using the
STcontroller application will continue to
function normally, even if the buttons are
in their locked-out state.
Configuration Storage
The selected configuration of the preampli-
fier gain and P48 on/off status, as well as
the button lock-out status, will be stored in
nonvolatile memory within the Model 5205.
This allows the settings to be “remembered”
during periods when the Model 5205 is not
being provided with power. Upon the unit
being powered up the stored settings will
again be used.
USB Interface
A USB type A connector and associated
status LED is located on the back panel of
the Model 5205. This data interface is used
only for updating the unit’s application firm-
ware. No audio data of any kind will pass
through it. For details please refer to the
Technical Notes section of this guide.
Technical Notes
IP Address Assignment
By default the Model 5205’s Ethernet inter-
face will attempt to obtain an IP address
and associated settings using DHCP (Dy-
namic Host Configuration Protocol). If a
DHCP server is not detected an IP address
will be assigned using the link-local proto-
col. This protocol is known in the Microsoft®
world as Automatic Private IP Addressing
(APIPA). It is also sometimes referred to as
auto-IP (PIPPA). Link-local will assign an
IP address in the IPv4 range of 169.254.0.1
to 169.254.255.254. In this way multiple
Dante-enabled devices can be connected
together and automatically function, whether
or not a DHCP server is active on the LAN.
Even two Dante-enabled devices that are
directly interconnected using an RJ45 patch
