xIO IP DSP Audio Expanders Tech Tips

This is a general-purpose step-by-step guide for connecting to Symetrix digital signal processors and related hardware with a PC. Please note that Symetrix only recommends using Windows 10 and above. Other operating systems are not officially supported at this time.

Step 1 – Install the right software for the device

Symetrix site design software is used to connect to Symetrix devices and is available to download, install, and run for free. The required software will depend on the devices that needs to be accessed:

Composer:

Current Symetrix open-architecture DSPs all use Composer, which can be downloaded here. These include:

• D100
• Radius
• Prism
• Edge
• Solus NX

Other Symetrix hardware that can be accessed through Composer will include:

• Endpoints and expanders (xIn, xOut, and xIO devices)
• T Series touch panels
• W Series wall remotes
• Control expanders (xControl, Control Server)

Important: To avoid errors when going online with the hardware, please download the version of Composer that matches the DSP’s firmware revision number as closely as possible. This number can be found by cycling through the system pages on the front LCD panel of the DSP.

Integrator Series:

Software for Symetrix’s current Integrator Series (closed-architecture) DSPs can be downloaded here. These include:

• Jupiter
• Zone Mix 761

Legacy Hardware:

Legacy open-architecture DSPs such as 8×8 DSP, Express CobraLink, and original Solus (non-NX) require SymNet Designer. This software has been discontinued and is no longer supported by Symetrix, but the final version (10.7) can be downloaded here. Software for all other legacy products, such as Zone Mix 760, AirTools-series, and Lucid-series, is no longer available for download.

Step 2 – Make sure the PC is on the right network

Once the correct software has been downloaded, the next step is to connect the PC to the device’s control network. If a DSP is Dante-enabled, make sure not to confuse the Dante ethernet port for the control ethernet port. Configuration of these devices through the Symetrix software is always done through the control port.

By default, Symetrix devices will obtain an IP address automatically, either from a DHCP server or, if a DHCP server is not available, by obtaining a link-local (169.254.x.x) IP address. Most Composer-enabled devices will display their IP address on the front LCD panel. Cycling through the system pages on the front LCD will additionally display the subnet mask. If a device has previously been configured with a static IP address, it can be reset to DHCP by briefly pressing the device’s reset button, which is usually recessed in the housing on the back of the device.

ncpa

It is important that the PC’s network settings match those of the devices being used in the system. To check this, enter ‘ncpa.cpl’ in the Windows search bar to open the list of network adapters on the PC:

Right click the network adapter that will be used to connect to the device, select ‘Properties.

version

Then double click ‘Internet Protocol Version 4’:

address

The network settings of the PC’s network adapter will display. If the Symetrix device is set to DHCP, select ‘Obtain an IP address automatically.’ Alternatively, a static IP address and custom subnet mask can be set here:

Important: Ensure that both the IP subnet and subnet mask of the network adapter match that of the device. If setting the PC to a static IP address, it must be a different/unused IP address on the network. If connected directly to the DSP with a static IP address, setting the PC to an address “right next to” the DSP usually safe. Example; if the DSP IP address is 192.168.100.50, set the PC to 192.168.100.51.

Step 3 – Locate the Symetrix hardware on the network

Once the PC is on the correct network, open the appropriate Symetrix software. The next steps will depend on the software being used.

Composer:

site

If a copy of the site file is available on the PC: Select the ‘File’ menu > Open and select it from File Explorer. In Site View, all located devices will have a checkmark in the lower left corner. If there is no checkmark present, click the empty box in the lower left corner of the device to open the Locate Hardware menu:

In the Locate Hardware menu, a list of available devices will appear. If necessary, click ‘Select Network to Search…’ to ensure that the correct network adapter is being used to scan for devices. Either double click the device in the list or highlight it and select ‘Locate to Selected Hardware’ to finish locating the device:

Repeat the above process for all devices in the Site View.

If the site file needs to be pulled from the unit:Go to the ‘Hardware’ menu > ‘System Manager’ > ‘Hardware’ tab. A list of all available units on the network will display. If needed, click “Select Network to Search…” to change the network being scanned for devices. Highlight the desired unit, then select ‘Go Online (Pull from Unit…)’:

The Pull Site File From Hardware Wizard will appear. Select a location on the PC where the site file will be saved, then click ‘Next’:

Next, select either ‘Yes – Synchronize to All Changes’ to keep any changes made to the configuration while last online with this site file, or ‘No – Abandon Changes’ to revert to the archived version of the site file. ‘Show Advanced Options’ allows for more granular control over which changes are kept when synchronizing:

Select ‘Next’, then either select ‘Finish’ to go online with the site file as-is or select ‘Cancel’ to make changes to the site file before going online:

A note about Dante devices– Any Dante devices in the design must be located through a Symetrix DSP that has already been located:

As of Composer 8.5, an xIO Updater/Configurator module may be added to the site view to configure Symetrix xIO Dante devices if a Symetrix DSP is not available. Symetrix recommends using separate networks for Dante and control.

Integrator Series:

Locating an Integrator Series DSP is done in the Connection Wizard of the Jupiter or Zone Mix 761 software. This can be done either by selecting ‘Existing File on Device’ > ‘Open Connection Wizard’ from the startup menu, or by selecting the Connection Wizard icon in the top ribbon:

Once the Connection Wizard opens, select the option that best fits the connection type, then select ‘Next’. A list of the PC’s network adapters will appear. Select the one that is connected to the ethernet port of the device, then select ‘Next’. Select ‘Open Network Connections’ to show these network adapters in Windows Control Panel if any settings need to be changed:

A list of devices will appear. Any devices not compatible with the current site file will be grayed out. Select the device, then select ‘Next’. Selecting the ‘Properties…’ button will allow a static IP address to be set for the device if desired:

On the final screen, select ‘Finish’ to close the Connection wizard. To go online immediately, ensure the ‘Go online now’ box is checked:

Step 4 – Go online with the system

Composer:

online

Once all devices in the site file have been located, select ‘Go online (push site file to hardware)’:

Note: The icon with the yellow arrow is for pulling the site file from the located hardware. Please see the passage entitled “If the site file needs to be pulled from the unit” in the previous section for more information on pulling the site file from the hardware.

Next, the Site Preferences window will appear. These are generally advanced options that can be left alone, however if Dante routing is being managed in Dante Controller rather than in Composer, uncheck the box next to ‘Configure Network Audio.’ Click ‘OK’ to proceed:

dialogue

At this point, if the site file has not yet been saved to the PC, the File Explorer will appear and prompt for a filename and location to save the file to. If any ARC remotes are present in the design, a dialogue will appear and ask if all remotes should be programmed now. Regardless of whether ‘Yes’ or ‘No’ is selected here, the system will continue to push and go online:

success

Once the site file has been successfully pushed, a success dialogue will appear. After clicking ‘OK’, the system volume will gradually ramp up unless the system mute is engaged:

Now that the system is online, parameters can be changed in real time, and signal meters will display their data. However, if any modules are moved, added, or deleted, or if any wires are changed, the system will automatically go offline. The site file must be re-pushed in order to go back online.

Important: The firmware versions of all devices in a Composer site file must match the version of Composer being used before going online with the system. If this is not the case, a message will appear prompting a firmware upgrade before the system can go online. Please refer to the Updating Firmware with Composer Tech Tip for further assistance.

Integrator Series:

After finishing the Connection Wizard, select the orange ‘Off-line’ button in the top ribbon. The drop-down arrow can be selected to choose which previously located device to go online with:

A prompt will then appear allowing the user to select whether to push the currently open configuration file to the device, or to pull the configuration file off of the device and save it to the PC.

Once the system is online, parameters can be changed in real time, and signal meters will display their data.

Integrator Series devices will operate normally with the factory firmware and should not require firmware updates to go online.

FAQs and Troubleshooting

“My device does not appear in the Locate Hardware menu.”

• Double check that the PC’s NIC and the Symetrix device are on the same network.
• Double check that the selected network in the Locate Hardware menu corresponds to the intended NIC.
• Change all octets of the IP address and subnet mask being searched for to ‘255’, uncheck the box next to ‘Don’t show located and enabled units’, and check the box next to ‘Show incompatible hardware’ in order to broaden the search as widely as possible.
• If a USB to ethernet adapter is being used with the PC, connect using a standard ethernet port instead if possible.
• Power cycle both the PC and the device.
• Re-seat the ethernet cable in both the PC and the device.
• Try a different ethernet cable.
• If the device is connected to the PC through a network switch, try a different switch port, or connect directly to the PC instead.
• If all else fails, disconnect the device from the network, reset its network settings by tapping the reset button once, then directly connect it to the PC (ensuring the PC is set to automatically obtain an IP address).

“I’m getting a ‘Failed to go online’ error message.”

• Disable Windows Defender Firewall and any third-party antivirus/firewall programs that may be blocking network traffic.
• Double check that the device firmware versions for all devices in the site file match the version of Composer being used (the first two numbers are most important).
• Power cycle both the PC and the device.
• If the device is connected to the PC through a network switch, try connecting directly instead.
• If a device cannot be located and is not needed in the site file, right click it and select ‘Disable Unit’.

“I can’t locate my Dante device.”

• Double check that the DSP is Dante-enabled by going to the ‘Tools’ menu > ‘Launch Remote Terminal’ > ‘Options’ menu > enable ‘Debug Mode’, then send the command info cards to the IP address of the DSP. If ‘Non-Dante Clock Card’ is displayed in the output under ‘Audio Network Card’, then the device does not have a Dante card installed. Please contact sales@symetrix.co to purchase one. If ‘No Card Present’ is displayed instead, there may be a problem with the Dante card.
• Double check that the Dante device is connected to the Dante port of the DSP.
• Connect the Device directly to the DSP’s Dante port, bypassing any network switches. If it can be located using this method, there may be a problem with the network.
• If all else fails, connect the PC to the Dante network, or directly to the Dante device, and verify that it appears in Dante Controller. If not, then there may be a problem with the Dante device, or it may be set to a static IP address outside of the Dante network.

“What does the yellow checkmark next to a device in Composer mean?”

A yellow checkmark means that the device is muted, while a green checkmark means that the device is unmuted.

The purpose of this tech tip is to provide information when troubleshooting Dante connection and subscription problems between two PHY Dante devices.

 

Symptom:
The system works correctly when it is initially connected and installed. Subsequently, the system suffers frequent dropouts of random Dante channels. The dropouts manifest as a couple of seconds of silence. When the devices are connected via a switch, the system functions normally without dropouts.

 

What is a PHY Dante Device?
A Dante device that does not have an internal switch. The Ethernet jack is connected directly to the Dante PHY (Ethernet physical transceiver), as opposed to through a switch. This includes many Ultimo-based devices on the market as well as the specific Symetrix hardware listed below.

 

Affected Symetrix Hardware:

• Prism (4×4, 8×8, 12×12, and 16×16)
• xIn 4
• xOut 4
• xIO 4×4

Dante devices on the market with two Dante ports (Primary and Secondary) have internal switches and will not be affected. This includes Symetrix Radius and Edge DSPs.

Why do you get dropouts when two PHY devices are direct connected?
When a PHY device is directly connected to another PHY device, audio glitches occur due to PTP (Precision Time Protocol – the Dante clock protocol) sync loss. If both devices use PHY-based Ethernet, there will be insufficient delay on the transmitted packet to properly calculate the 1588 time. Adding a switch, creates sufficient packet delay to allow the calculation to be significant. This is a fundamental operational/mathematics issue. It is not something that can be adjusted. As such, it cannot be accounted for or fixed by firmware.

Dante networks require a switch to be compliant. Typically, there are one or more Brooklyn II-based products in a system which include an internal switch, particularly if they support daisy-chaining or redundancy. However, if the Brooklyn II-based product is only using PHY-based Ethernet, it is subject to this limitation.

Solution:
For this situation, the only resolution is a switch. A PoE injector is a pass through device and will not resolve the problem. When connecting Symetrix hardware with single Dante ports to each other, an external switch will always be needed. Example: Prism 4×4 to xIn 4. When connecting Symetrix hardware with a single Dante port to a device with dual Dante ports an external switch is not needed. Example: Radius 12×8 EX to xIn 4.

A Symetrix system’s I/O can be comprised of a combination of hardware, from DSPs such as D100, Edge, Radius NX, or Prism to the I/O expanders such as the xIn12, xOut12, and xControl. Pushing the site file programming from the host PC running Composer Software to the system can take anywhere from a few seconds to a few minutes depending on the amount of hardware that must receive programming.

Often times during commissioning, pushing the file to the system will be performed many times over as changes are made to the signal flow, remote controllers, presets, or parameters, and of which it is desirable to listen to these changes and/or to save these changes permanently in the system. By speeding up the Push process, it is possible to shave many minutes off of the overall commissioning time of the system.

The first thing to note is that all control and routing is truly performed in the DSP units. No processing or control is actually performed in the xIn 12, xOut 12, or the xControl, as once programmed these devices simply send audio or control to the d100, Edge, Radius NX, or Prism.

What this means is that once the xIO have had their programming pushed into them, then changes to the site file signal path, DSP modules, or control will not typically include changes to the xIO devices. As such, disabling them from the Push process will eliminate needlessly reloading the same programming into these devices whose settings/programming is not changing between each subsequent push.

Take this example site file. It includes Edge, Radius NX, xIn 12, xOut 12, and xControl hardware. Before disabling the xIO units from push, first locate all hardware and push the design (F4) to program all hardware, including the xIO devices.

Then right click the xIO hardware and choose “Unit Properties”. When the Unit Properties window pops up, uncheck the enable box (highlighted in red below). Doing this will disable the unit from each subsequent push of the site file. Disabling a unit does not affect the unit’s functionality. To repeat, the
disabled units will continue to operate normally and communicate to the DSP hardware, they will simply be ignored by Composer software during the push process.

Once all xIO units are disabled, the push process will now update only the programming on the Edge, Radius NX, Prism, and D100. And as this document explains, over the course of the commissioning process, eliminating unnecessary units from being reprogrammed over and over will shave many minutes off the commissioning process.

It should also be noted that at any time these disabled xIO units can have their configuration edited by simply checking “enable” in the Unit Properties, making the necessary changes, and pushing the file.
