INTRODUCTION
2.1. Purpose
The FLX-AES50 device is a digital audio converter, providing two built-in AES50 interfaces (96x96 channels @ 48kHz) and 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 AES50 and an AUX card (AES50-to-anything).
Transfer AES50 over fiber (DN9620 replacement, with AUX-MADI-SFP card), or AES50-over-Dante (with AUX-DANTE card) while maintaining full headamp control.1
standalone in-line: signals are transparently passed between both AES50 ports and split to the AUX card (plug-in recording split), while maintaining stagebox remote control
together with another flexiverter, connected via FlexLink (for up to 160x160 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.

3.3. FlexLink connection
The FlexLink connection is designed to connect Flexiverters with each other, or with the Multiverter. It provides:
192x192 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.

User's Manual
LED color

green white red
red blinking yellow blinking
Meaning
Interface not active / involved
IN and OUT valid
OUT valid, but no IN detected
No valid signal or no valid clock. If the clock LEDs show red, make sure the clock mode is set
correctly and a valid clock is supplied. If the clock LEDs show green, the clock is ok but the input is not
detected. Check the respective connection. Interface is currently booting and not yet active Mode setting active: Alternately blinking LEDs indicate the interfaces between which data is converted; constant lit LEDs indicate splitting destinations. Press MODE button again to cycle through available modes. After 4 seconds, the selected mode is applied automatically.
4.2. Selecting the Route Mode
Long-press the Mode 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 Mode 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.

User's Manual 5.2. Selecting the Clock Source
Long-press the Clock button until the LEDs are blinking yellow. Current clock source/modes is shown by blinking LED(s). Press the Clock 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!

REMOTE CONTROL
6.1. Browser-based control
This does not require any software to be installed. It works as hybrid app where the user interface is fetched from the web, and your browser talks to the device via USB connection.
Web control requires "Web Serial API" which is currently only available in Chrome, Edge and Opera on Windows and Mac. Not supported on mobile devices and Safari/Firefox.
To use web control,
Connect the device to your computer using an USB cable Open your browser and go to appsys.ch/remote When the browser requests access to the serial port, give permission on the
first port listed
6.2. Command line control
A command line is available via the USB serial port. To use it, you need a terminal software (Hyperterminal, PuTTY, minicom or similar) which can talk to a serial ("COM") port.
To use the command line,
Connect the device to your computer using an USB cable Open the terminal software. Select the first COM port which appears when
plugging in the device Select 115200 bps, 8N1 as communication parameters To see what you're typing, turn local echo "on" in the terminal software To see a list of available commands, type help at the FLX> command prompt

User's Manual
9.3. 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 AES50 Port A to Port B using a standard Cat5 cable 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.
9.4. 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-AES50 Unpack the firmware package FLX-AES50-Firmware_x.y.zip Connect your PC via USB to the flexiverter Power ON the device Run the FLX-AES50_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.
