on to the Subnet Mask screen which will
display the currently-stored value. Again
use the pushbuttons to make any desired
changes followed by pressing the Enter
button. A prompt will then display asking if
a reboot is desired. Select Yes to reboot
the interface using the revised IP address
and subnet mask values.
Whenever an interface determines that a
configuration change has been made an
indication is shown in the LCD display’s
lower-right corner. Consisting of [!], it will
only stop being displayed after that spe-
cific interface has been reboot or after the
entire Model 48D has been rebooted. Op-
eration will continue when [!] displays but
it’s likely that the operating IP address and
subnet mask values will not be the same
as those stored in the Model 48D.
Note that the Model 48D will display [!]
even if a change was made and then
“unmade.” The firmware is not sophisticat-
ed enough to determine that a parameter
that was changed has been returned to its
original value. Only a reboot will cause the
[!] to no longer be displayed.
Operation
At this point the Model 48D should have
Ethernet connections made to the two
network interfaces. Depending on the
capabilities of the Ethernet connection
made to Network A, a source of 12 volt
DC power may also have been connect-
ed. Using the Dante Controller software
and/or the front-panel LCD display and
pushbutton switches the network-related
configuration settings should have been
made. The audio sample rate and AES67
support status for each network interface
should have been selected using Dante
Controller. For each network interface the
four Dante output (transmitter) channels
and four Dante input (receiver) channels
should have been routed (subscribed)
using Dante Controller.
Initial Operation
The Model 48D will begin functioning
within a minute of its power source being
connected. As previously discussed, the
unit’s power source can be provided by
Power-over-Ethernet (PoE) on Network
A or an external source of 12 volts DC.
If both are connected the PoE source will
power the unit. Should PoE power subse-
quently no longer be available to Network
A, uninterrupted operation will continue
using the external 12 volt DC source. (This
will probably prove to be a “hollow” vic-
tory since a loss of PoE will probably also
mean a loss of the required Ethernet data
connection!)
Upon the Model 48D receiving power the
status LEDs will light in various manners.
The Ethernet and Dante interface status
LEDs, located below the RJ45 receptacles
on the back panel, will light in various
ways. On the front panel the four status
LEDs and the LCD display will light in a
defined sequence. Once this startup se-
quence has completed the unit will begin
operation.
Upon power up the front-panel LCD dis-
play will first show the Studio Technologies
logo, followed by the product name and
then the main firmware version number.
After that the Model 48D’s menu system
will be active with the network-related
fields displaying Net Starting… as the
Dante connections are being established.
