Receiver Configuration

Is there a checklist for configuring the SFX 4104 receiver?

Yes, here’s a list of items to check before you start operations with your SFX 4104. The following list assumes basic familiarity with the SFX web GUI conventions.

If, after checking these items, you are still having problems receiving files or audio streams, contact the PRSS Help Desk at 800.971.7677 or via email at prsshelp@npr.org.

Most important first step: Check the ContentDepot Portal to determine which of your SFX4104 receivers is “Pro Audio 1” and which is “Pro Audio 2”, and so forth.

To find the assignments:
1.    Log into the ContentDepot Portal;
2.    Go to “Profile” (on the lower left side of the page);
3.    Click on the “Customer Information” link;
4.    Go to the “Delivery” tab where the serial numbers listed under “V2” indicate how your receivers are assigned

NOTE: When you look at your program subscriptions in the ContentDepot portal, keep in mind that the new Pro Audio receivers are the “V2” receivers on all reports and subscription pages.

After installing your new receivers, wait at least 24 hours to allow the system to automatically load the latest software on your receiver and then confirm the settings below (these settings are organized by the tabs on the receiver’s home page):

Identity Tab:
1.    Identity page: Confirm latest software versions are loaded:

Product number: 92084590 or 92083950
Firmware Version: 2.21
Livewire Version: 1.3
XD Version: 1.14
LiveAssist Version: 1.10
proAudio Version: 1.7
DAs: 911, 928, 1401, 1430
Board Revision: 6

2.    Identity page: Set Sat0 IP = 10.255.255.3   Sat1 IP = 10.255.255.4
3.    Identity page: Make sure Net1 (Eth0) and Net2 (Eth1) are on different subnets
4.    Identity page: If you don’t need to set a default gateway, make sure that field is blank (it could slow down page load and network operations otherwise).

DVB Carrier Tab
1.    DVB Carrier: Tuner Mode puddle – Dual Tuner; Input = Common; Data Output = Independent
2.    DVB Carrier: L-Band 2 LNB Attributes puddle – Supply Select: Enabled

Audio Tab:
1.     Audio - Audio Configuration puddle – Ensure Livewire is disabled for each output if you do not intend to use Livewire.  Note: When Livewire is enabled, analog and AES/EBU audio outputs and associated metering are disabled.

2. Audio Configuration – Under ProAudio Output verify that the Interface: field says “ Satellite (sat0)  if it says anything else it will not process audio from the satellite for that channel. Scroll down the page and ensure this setting for each of the four ProAudio Outputs 1 - 4.

Channel Guide tab: If all four audio players are on Channel 8 Classical 24, then cycle power to the 4104.  This setting resulted from a default parking of the channels when they were originally shipped

Data Delivery Tab:
1.    Data Delivery – L-Band 1 Pids and Ports puddle – Ensure that the Net Port(s) enabled checkbox is checked. Also ensure pids 601, 4152, 4153, and 4155 are listed and enabled.  The other pids listed here 1001-1045 odd numbered will be enabled randomly according to responses to your station’s subscriptions set up in the ContentDepot web portal.
2.    Data Delivery – L-Band 2 Pids and Ports puddle – Ensure that the Net Port(s) enabled checkbox is checked. Also ensure Pids 600 and 4152 are listed and enabled here.

XD Tab:
1.    XD – XD Client puddle – Ensure XD Client and XD Dataman status are Green.
2.    XD – XD Client puddle – Channel 1 In Adapter = Satellite (sat1)  Channel 2 in Adapter = Satellite (sat0)
3.    XD – XD License Info: puddle – Ensure box has a valid Site ID (Not zero)

Configuration Tab:
1.    Configuration – Ethernet Configuration puddle – set eth0/eth1 to Auto-Negotiate.  Hit send update twice.
2.    Configuration  – SSH puddle – Ensure Allow Users = Admin, Monitor, and User
3.    Configuration  – Samba puddle – Set All shares Read/Write

 

 

Program Subscription

Can I subscribe to the same program episode on more than one audio port?
If you require backup for a particular program stream, you can assign a single program episode to a maximum of two ports. Please be aware that attempting to add a third port to the subscription will result in the ContentDepot returning an error message.

What will happen to our existing subscriptions when we convert to the SFX 4104? Will stations have to resubscribe their programs?
Prior to shipping your SFX 4104s, all of your station’s existing ContentDepot subscriptions (for both file-based and live programs) were automatically replicated on the new units. This process did not affect or change existing subscriptions in any way.

We automatically assigned ports on the new SFX4104 receivers based on your stations’ existing subscriptions. The receivers were mapped one of two ways:

Subscription Data Replication (Option 1)

Old:                                New:
Decoder 1, Port 1       SFX4104 1, Port 1
Decoder 1, Port 2       SFX4104 1, Port 2
Decoder 2, Port 1       SFX4104 2, Port 1
Decoder 2, Port 2       SFX4104 2, Port 2
Decoder 3, Port 1       SFX4104 1, Port 3
Decoder 3, Port 2       SFX4104 1, Port 4
Decoder 4, Port 1       SFX4104 2, Port 3
Decoder 4, Port 2       SFX4104 2, Port 4

Subscription Data Replication (Option 2)

Old:                                New:
Decoder 1, Port 1       SFX4104 1, Port 1
Decoder 1, Port 2       SFX4104 1, Port 2
Decoder 2, Port 1       SFX4104 1, Port 3
Decoder 2, Port 2       SFX4104 1, Port 4
Decoder 3, Port 1       SFX4104 2, Port 1
Decoder 3, Port 2       SFX4104 2, Port 2
Decoder 4, Port 1       SFX4104 2, Port 3
Decoder 4, Port 2       SFX4104 2, Port 4

These data replication options cover the majority of stations that have four or fewer stream decoders. There are mappings for stations that have more than four stream decoders and have purchased a third (or fourth. . .) SFX4104 receiver.

The assignments are designed to cover most stations’ needs without having to touch every subscription. If these assignments aren’t appropriate for local needs, station staffers are free to make any subscription changes needed after installing their new SFX 4104 receivers.

On request, ContentDepot administrators can also change a station’s assignments in two ways:

  • First, ContentDepot administrators can “reset” a station’s SFX4104 assignments to the standard mapping listed above. This might be handy if a station staffer needs to “start over” after making local changes to their SFX4104 assignments that are unworkable.
     
  • Second, ContentDepot administrators can remove all SFX4104 assignments, leaving it up to station staffers to reassign each individual subscription to locally-appropriate ports. There aren’t many scenarios where this would be necessary, but it’s an option if a station needs it.

ContentDepot administrators will not be able to apply SFX4104 assignments other than the standard mapping or to clear all SFX4104 assignments for a station.

To be clear, none of the above will change existing subscriptions or assignments to existing SR2000 stream receivers in any way.

You should also beware that if you have subscribed to additional shows since receiving your new units, and have assigned those shows to ports on your SR2000pros, you will have to manually assign those shows to ports on the SFX 4104s.

 

Receiver Cost

 

How much does the SFX 4104 receiver cost?
The price for the SFX 4104 receiver is $4,813 each through the PRSS. Before you decide whether you need more receivers, remember that you’re getting eight audio ports over the two new receivers—double the capacity of two old receivers.  Click here for the receiver order form.

 

File Deletion

I am unable delete files from my receivers via the network shares. My automation system needs to delete files from the CDLongname (or CDCutID) folder to work properly, but can't remove them.
Some of the new receivers were shipped from IDC with their Samba servers (the software that shares directories to networked computers) incorrectly configured. To change it:

Log into your SFX4104 receiver in the usual way, and then:

  • Click the Configuration tab on the home page;
  • Click the "Samba" puddle;
  • Click the "All Shares Read/Write" button on the left navigation bar;
  • Click OK on the dialog box that is displayed.

 

Automation

Why is it taking so long for program files to move from the SFX 4104 to my station’s automation system?
The problem may be the result of an incorrect setting of the SFX 4104’s network interface controller (NIC). In order to avoid unusually slow file transfers to your automation system, the NIC must be set to “auto-negotiate.”
 
To verify or change the NIC setting on the SFX 4104, access the receiver's GUI and take the following steps: Click on "Configuration Menu," followed by "Ethernet Configuration Puddle," choose "Edit", change the NIC setting to auto-negotiate and then save the change by choosing “Send Update.”  Note: You may need to reboot the receiver for the setting to take action.

 

 

Decoder Port Assignment

If I assign a subscribed program to a port on one of my station’s SR2000pro stream decoders, will that assignment automatically carry over to one of our new SFX 4104 receivers?
 No. Before shipping your new receivers, we took steps to automatically migrate all of your station’s program subscriptions to the SFX 4104s. However, if you have subscribed to additional shows since receiving your new units, and have assigned those shows to ports on your SR2000pros, you will have to manually assign those shows to ports on the SFX 4104s.

How do I know which of my new SFX4104s works with a specific portal subscription?
You can determine the correct match by reviewing the information that is listed for each of your receivers in the ContentDepot portal. This information is located under the "V2 Equipment" listing which can be found by clicking on the "Delivery" tab of your customer "Profile." Here you will find the serial numbers for each of your SFX4104s. Install the new receivers in your equipment racks accordingly.

 

Axia Livewire

Is the SFX 4104 receiver capable of supporting Audio over Ethernet (AoE) systems such as Axia LiveWire?
Axia LiveWire is currently the only AoE system supported on the SFX 4104. For complete instructions on how to configure the receiver for LiveWire, please refer to page 24 of the IDC SFX Pro Audio Series Satellite Receiver Addendum delivered with the receiver. We’ll let stations know when the SFX 4104 is capable of supporting other AoE systems.

Why am I experiencing audio glitches when using the SFX 4104 receiver with Axia Livewire enabled?
The glitches stem from a mismatch in the configuration of the receiver’s network interface controller (NIC) and the configuration of the associated NIC of the Axia network switch port.  Axia recommends that all ports in the Axia network switch be set to auto-negotiate. So, in order to avoid audio glitches, please ensure that the SFX 4104’s Livewire enabled NIC is also set to auto-negotiate.
 
To verify or change the NIC setting on the SFX 4104, access the receiver's GUI and take the following steps: Click on "Configuration Menu," followed by "Ethernet Configuration Puddle," choose "Edit", select your Livewire enabled receiver NIC, change the NIC setting to auto-negotiate and then save the change by choosing “Send Update.”  Note: You may need to reboot the receiver for the setting to take action.

 

Manual Tuning

Why aren’t the new SFX 4104 Pro Audio receivers configured to allow for manual tuning?
The new receivers have been designed to operate as part of a fully networked system, which requires them to function exclusively in automated mode. By running in automated mode, stations will automatically receive new software updates, tuning commands and other services that will be developed and provided in the future. It also provides producers with the ability to track which stations are subscribing to their programs.

In the event of an emergency, how are stations supposed to recover if they’re not able to manually tune their SFX 4104 receivers?
While the new receivers do not allow for manual tuning, stations have the option of keeping their legacy SR 2000pro receivers manually tuned to program streams as an emergency back-up.

 

Ongoing SR 2000pro Support

Will the PRSS continue to support the maintenance of the SR 2000pros?
The PRSS no longer supports the SR2000pro receivers, and stations who continue to use them should be aware that they are approaching end-of-life status.

 

Connectors

Why does the SFX 4104 receiver have DB 9 and DB 15 connectors instead of the XLR connectors featured on the previous units?
The DB 9 and DB 15 connectors on the new receiver are the standard issue provided by the manufacturer. Asking the manufacturer to install other types of connectors would have added to the cost of each receiver.

 

Codecs

Does the PRSS plan to phase out use of MPEG Layer 2 codec?
While the SFX4104s are capable of handling several different algorithms, we plan to continue using the MPEG Layer 2 codec for the foreseeable future.

 

Sample Rates

Is the sample rate for the SFX 4104s playout 44.1 kHz or 48 kHz?
With SFX 4104, stations can select either sample rate.

 

Windows Updates

After the most recent Microsoft Windows update, I can't connect to my SFX 4104's web page with Internet Explorer 9. Are there any workarounds for solving this issue?
Microsoft has forced the latest version of Internet Explorer to disallow any certificates with less than 1024 bits (like the certificates in the SFX 4104 receivers). For a technical explanation:
http://support.microsoft.com/kb/2661254
 
This does not in any way affect file or stream operations with your receivers; it only affects using a web browser to connect to your new receivers.
 
Until IDC produces an update to the certificates in the receivers, here are two workarounds:
 
Use Chrome or Firefox browsers to connect to your receivers, OR
 

If you use Windows Vista or Windows 7, enter the following commands from a command prompt on your Windows computer:

certutil -setreg chain\minRSAPubKeyBitLength 512
certutil-setreg chain\EnableWeakSignatureFlags 2

then restart Windows.

If you aren't comfortable with command-line operations in Windows, do not attempt the second workaround; use a different browser to connect to your receivers.
