INTRODUCTION

Purpose
The FLX-DANTE device is a digital audio converter, providing a built-in Dante® network interface, and an additional slot for one AUX card. It can be used in different setups, depending on the user’s needs:

• standalone, to convert between the built-in Dante and an AUX card(Dante-to-anything).
• standalone with installed AUX-DANTE card as Dante-to-Dante bridge (network isolator). In this setup, two different Dante networks can be kept physically separate but it is possible to pass audio between them.
• together with another flexiverter, connected via FlexLink (for up to 128×128 channels),
• together with the multiverter, connected via FlexLink. This provides remote control, channel-wise routing and SRC (Sample Rate Conversion). In this mode, Dante-to-Dante bridging with sample rate conversion is also possible.

For a detailed description of possible configurations see 3 . Possible Setups.

FlexLink connection
The FlexLink connection is designed to connect Flexiverters with each other, or with the Multiverter. It provides:

• 192×192 channels bi-directional transmission of 24-bit uncompressed audio (fully transparent to AES3 compatible metadata bits)
• Super-low link latency of 4 samples (ca. 83μs)
• Dedicated, high-quality reference clock signal with automatic configuration
• Power supply for connected devices (to reduce cabling), alternatively serves as redundancy scheme when both devices are powered: in case of power failure, both devices keep working from the remaining power supply.
• Uses standard HDMI cables (with locking screws), to provide easy field replacement in case of defects.

AUDIO ROUTING

The flexiverter can operate in various routing modes, allowing you to pass audio between the available interfaces in many different ways. The LEDs in the “MODE” section indicate the involved interfaces.

Modes and indication

Selecting the Route Mode

• Long-press the button until the LEDs are blinking yellow.
• Current routing mode is shown by alternately yellow blinking LEDs, indicating the interfaces where the signal is passed between.

All incoming data is also split (output) to FlexLink: AES50 Port A is split to Lane 1 (ch1-64), AES50 Port B is split to Lane 2 (ch65-128) and AUX is split to Lane 3 (ch129-192). The split is not indicated on the LEDs for clarity but is always active.

• Press the button repeatedly to cycle between available modes, until the desired mode is shown.
• After four seconds without interaction, selection mode is terminated and the current setting comes into effect.

Remarks

• Routing between the selected interfaces is always bi-directional, meaning that audio is passed between them both ways. A working bi-directional link shows green for both interfaces. If the LED shows ⚪ white, the corresponding interface does only output data but no input on it has been detected. If the LED shows red, the interface is not connected, or the clock is invalid or missing.
• Channel-wise routing and splitting (crosspoint switch/matrix) between all channels is possible when the flexiverter is connected to a multiverter. Routing is then done via the multiverter’s web interface or via the command line.

CLOCK SETTINGS

Clock sources and indication
The flexiverter can be clocked from every interface (acting as clock slave), or can run on its internal clock (acting as clock master).

clock source. After 4 seconds, selection mode is terminated and the selected mode comes into effect.

Selecting the Clock Source

• Long-press the button until the LEDs are blinking yellow.
• Current clock source/modes is shown by blinking LED(s).
• Press the button repeatedly to cycle between the available clock sources. Depending on the source, you might need to select the desired sample rate ( 44.1 kHz or 48 kHz) and/or the appropriate multipliers ( x2 / x4).
• After four seconds without interaction, clock setting is automatically terminated and the selected clock source comes into effect.

When the samplerate is incorrectly set (e.g. 48k with 96k data), unwanted effects (double samples, zero samples, channel crosstalk etc.) may occur and might not be noticed immediately. Always double-check that the samplerate is set correctly on all involved devices!

ACCESSING INTERNALS

Opening the device

• Required: Torx T10 screwdriver.
• Power off the device and detach all cables to avoid short-circuit or damage.
• Detach the device from the rack-mount kit.
• Remove the four top screws and the top cover by pulling it upwards:

Inside view

1. Screws for AUX cover plate
2. AUX card connector

Installing AUX cards

• Remove the screws holding the cover plate, and the blank cover plate ➊
• Insert the AUX card from inside, using the supplied cover plate.Make sure it is correctly fitted to the card connector➋
• Secure the card using two cover screws ➊
• The card has been installed correctly if you are able to select an audio routing mode involving AUX (long-press MODE button to enter Route Mode Selection).

DIP SETTINGS

Fine-tuning of the flexiverter’s built-in interface behavior and of the AUX card can be achieved via DIP settings on the back side. Changing the DIP settings will come immediately into effect. DIP switches 1,2,3 are reserved for future use.Default setting: all switches up.

AUX config (DIP4..6)
Many AUX card provide additional settings, which can be adjusted using these switches. The actual meaning depends on the type of AUX card installed:

Default setting

For cards not listed, refer to the manual of the respective card, or check for a newer version of this manual.

Applies to outputs only. Input format is always auto-detected, regardless of the switch setting

FlexLink channel mapping (DIP7..9)
The FlexLink interface can transmit 192×192 channels, organized in three lanes with 64 channels each. The channel assignment can be adjusted to meet the user’s needs, particularly when the device is used in double-FLX configuration (to make sure that all interfaces and channels are mapped to the desired target on the peer FLX device).

Default setting

SPECIAL OPERATING MODES

Special operating modes are accessible by holding down the button while switching on the device. Press again to switch to the next mode:

Version Display

• The firmware version “X.Y” and the hardware version “Z” are shown on the LEDs on the front panel:

  • The number of pink LEDs lit indicate the major firmware number “X”
  • The number of orange LEDs lit indicate the minor firmware number “Y”
  • The number of green LEDs lit indicate the hardware version “Z”
    Example: One (1) pink LED and three (3) orange LEDs means “Firmware 1.3”, zero green LEDs mean HW version 0.

• Blinking LEDs mean that the currently installed firmware is a “beta” version. It is advised to upgrade to an official release version as soon as it is released.

• Press again to proceed to LED test.

LED Test

• All LEDs on the front and on the back should show ⚪ white.
• Press again to proceed to Interface Self-Test.

Interface Self-Test
All built-in interfaces and the optional AUX card can be tested for correct operation by the user. This is done using the special self-test mode, in which the device outputs a special random test pattern on all channels. This pattern is looped back via an external cable into the corresponding inputs, where it is checked for consistency.

• Self-test mode is indicated with “CLOCK” showing INT/48kHz in cyan color. The “MODE” LEDs indicate red (error/no connection) or green (loopback data received ok) for the respective interface.
• Connect the Dante Primary port to your network.
• Connect the Dante Secondary port to a separate switch. Note: This switch should NOT have any other connection to your network, otherwise there is a chance that your LANs forwarding rules are messed up– it can take hours until everything works again!
• If an AUX card is installed, connect all output ports of the AUX card to the respective inputs using a loop-back cable. Note: NOT supported with AUX-ADC, AUX-AES67, AUX-AVB, AUX-DANTE.

Firmware update
This is a two-step process:

1. Base Device firmware is updated through the USB port on the rear
2. Dante firmware is flashed on the built-in Dante module over the network

You must always update BOTH the base device (over USB), and the Dante firmware (over the network), because both firmware versions are mutually coordinated.

Preparation

• Download the latest firmware from www.appsys.ch/FLX- DANTE
• Unpack the firmware package FLX-DANTE-Firmware_x.y.zip
• Connect your PC via USB to the flexiverter
• Connect one of the Dante ports to your local network
• Power ON the device

Updating the base device (over USB)

• Run the FLX-DANTE_Updater.bat file from the firmware package and follow the instructions on the screen.
• Power cycle the device to effect the base device update

Updating the Dante firmware (over Network)

• Use Dante Firmware Update Manager (or Dante Updater built into Dante Controller) to flash the firmware\FLX-DANTE_x.x.x.x.dnt file contained in the firmware package onto the device.
