INTRODUCTION

2.1. Purpose
The FLX-MADI device is as digital audio converter, providing two built-in MADI interfaces and a third one (or many other interfaces) with optional AUX cards. It can be  used in different setups, depending on the user’s needs:

• standalone, to convert between the built-in MADI ports (media converter),
• standalone, to convert between one of the built-in MADI ports and an additionAUX card (MADI-to-anything),
• together with another flexiverter, connected via FlexLink (for up to 192×192 channels),
• together with the multiverter, connected via FlexLink. This provides remote control, channel-wise routing and SRC (Sample Rate Conversion).
  For a detailed description of possible configurations see 3 . Possible Setups.

2.2. Box Contents

• 1 FLX-MADI Converter

3.1. Available AUX cards
At the time of writing (2021-11), the following AUX cards are available. More will come, please check www.appsys.ch for updates.

3.2. Available FLX devices
At the time of writing (2021-11), the following FLX devices are available. More will come, please check www.appsys.ch for updates.

3.3. 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 (MADI SFP, MADI coaxial, AUX and FlexLink) in many  different ways. The LEDs in the “MODE” section indicate the involved interfaces.

4.1. Modes and indication

2 All incoming data is also split (output) to FlexLink: MADI SFP is split to Lane 1 (ch1-64), MADI coaxial 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.

4.2. 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.
• 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.

4.3. 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

5.1. 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).

5.2. Selecting the Clock Source

• Long-press the button until the LEDs are blinking yellow.
• Current clock source/modes is shown by blinking LED(s).

ACCESSING INTERNALS

6.1. 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:
  

6.2. Inside view

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

6.3. 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. Default setting: all switches up.

7.1. Base device config (DIP1..3)
The configuration below affects only the MADI outputs. The input format is automatically detected, independent of the DIP switch settings.

7.2. 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:

For cards not listed, refer to the manual of the respective card, or check for a newer version of this manual.

7.3. 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.

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:

8.1. 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.

8.2. LED Test

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

8.3. 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 Output to the Input of the MADI SFP Port using an optical cable.

• Connect the Output to the Input of the MADI Coaxial Port using an coaxial (BNC) cable with 75 Ohms impedance.

• 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 AUXADC, AUX- AES67, AUX-AVB, AUX-DANTE.

8.4. Firmware update
The firmware can be updated from any Windows PC over the rear USB port.
▶ To update:

• Download the latest firmware from www.appsys.ch/FLX-MADI
• Unpack the firmware package FLX-MADI-Firmware_x.y.zip
• Connect your PC via USB to the flexiverter
• Power ON the device
• Run the FLX-MADI_Updater.bat file from the firmware package and follow the instructions on the screen.
• Power cycle the device to effect the update.

****Thanks to the special design of the updater, it is virtually impossible to damage (“brick”) the device during update. If updating fails or is interrupted, restart the procedure.  You can also can go back to any older firmware version at any time.
