end of this boot time the Linux CPU reestablishes
communications with the HD Radio DSP and with
the HD Radio Exciter. The HD Radio DSP board
can then begin processing the incoming audio,
which will take roughly seven to fifteen seconds
to make it through the processor and out the Eth-
ernet connection to the HD Radio Exciter.
During this time the analog broadcast audio
continues, but in a non-delayed state. The Blend
control bit is turned off until the Diversity Delay
completes rebuilding to its set length. Once the
Diversity Delay is ramped back to full, the Blend
function is turned back on since the analog broad-
cast is now time locked to the HD Radio audio.
5.3.1 HDE-200 DEVICES DO NOT
SHOW UP IN THE ECC APP
When no HDE-200 devices appear in the HDE-
200 Exporter Control Center list of devices to con-
nect to—even though one or more HDE-200 de-
vices are responding to pings from the computer,
then there are typically three possible causes:
• The FlexStar Network Interface (
System
Preferences
) address has a typo, the wrong
NIC was assigned, or the FlexStar network
cable is plugged into the wrong NIC.
• The FlexStar Multicast settings differ from
the default setting of 239.255.255.1, port
50010 in the ECC app or on the HDE-200
device. For most installations the default
settings should be used.
• The Windows Firewall is enabled and is not
configured to allow HDE-200 messages or
ECC app communications through the
firewall.
Any one (or more) of these configuration errors
will cause the multicast messages, transmitted by
the HDE-200 devices, to not be received by the
ECC app. Subsequently, this means that the HDE-
200 devices will not appear in the select device
list.
Check that the NIC address for the computer’s
interface to the FlexStar network is set correctly
and verify the FlexStar Multicast settings are cor-
rect. If both were set correctly then the issue is
most likely associated with the Windows Firewall
settings.
Windows Firewall is automatically disabled in-
side the Harris domain network. However, when
a user logs into Windows but does not use the
Harris domain, the default setting for the Win-
dows Firewall (for WinXP SP2 and later) is auto-
matically enabled. This enabled setting will block
multicast messages sent by the HDE-200 from
being received by the ECC app.
5.3.2 CONFIGURING THE FIREWALL
TO UNBLOCK THE ECC APP
A security alert pop-up window, shown below,
appears if the ECC app is started and Windows
Firewall is blocking the HDE-200 multicast mes-
sages. Click
Unblock so Windows Firewall will al-
low these communications to reach the ECC app.
The HDE-200 should now appear on the select
device list.
If the Windows Firewall was incorrectly config-
ured (e.g., someone previously clicked Keep Block-
ing
) or the pop-up window does not appear, then
the Windows Firewall configuration will have to
be manually changed. Open Windows Firewall
(
Start/Settings/Control Panel/Windows Firewall )
and select the Exceptions tab.
