INTRODUCTION
2.1. Purpose
The FLX-AES3/SRC device is as digital audio converter, providing up to 16x16 channels (8x8 lines) of AES/EBU, with individual Sample Rate Conversion for each AES3 input line. This makes it possible to bring differently clocked inputs to a common output clock.
The device can be used in different setups, depending on the user's needs:
standalone, to convert between the built-in AES3 ports and an AUX card together with another flexiverter, connected via FlexLink 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.

User's Manual
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.3 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.
When routing channels to the AUX or FlexLink interface, channels of AES3 Port A and B are concatenated together and appear on the FlexLink interface channels 1-16 and vice versa. The channels of the AUX card can either be mapped to the FlexLink interface directly after that (commencing at channel 17), or to a different block. See 8.4. FlexLink channel mapping (DIP3, 7..9).
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.
3 The SRC is only in the AES3 Input path. The output rate of AES3 is equal to the system clock.

User's Manual 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!

7.4. Variable DB25 pinout
Historically, there are two different pin assignments for the AES/EBU DB25 connectors around, commonly known as "Yamaha" and "Tascam" style. The FLXAES3/SRC supports both pinouts by means of internal jumpers. Pinout can be set for both ports independently, meaning you could use the FLX-AES3/SRC as cabling adapter. To select the pinout:
Locate the jumper blocks and/or and move all jumper blocks (3 each) to
the desired position.
CAUTION: Take care when remove the jumper blocks, pulling both sides equally gently upwards. You might use a knife or a screwdriver to push the blocks upwards. Make sure not to bend any pins!
The jumper position is not visible when the case is closed, but you can determine it from the color of the LEDs on the back side.

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.
8.1.
Base device config (DIP1..2)
Single Wire (full channel count at 48k, 96k and 192k), 1 2 professional format for metadata* Double wire (half channel count), 1 2 only in 96k and 192k modes Quad wire (quarter channel count), 1 2 only in 192k mode Single wire, 1 2 SPDIF (consumer) format for metadata * Default setting
Single Wire / Double wire / Quad wire: This is to maintain compatibility with legacy devices. Has only an effect for 88.2/96/176.4/192kHz data (44.1/48kHz data is always "single wire").
In Single Wire mode, always two channels are sent per AES3 connection. In 96kHz modes, they are sent at twice the speed as with 48kHz, and at quadruple speed in 192kHz modes. Supported by most up-to-date devices.
Double Wire mode is a legacy technique to send 96kHz data over 48kHz links, by halving channel count (one channel per AES3 connection). It is also sometimes found on 192kHz devices, allowing 192kHz data to be sent over 96kHz links.
Quad Wire mode takes this principle further by allowing 192kHz data to be sent over 48kHz links, by quartering the channel count (0.5 channels per AES3 connection).
SPDIF: Metadata is sent as"consumer" (S/PDIF) format instead of "professional" (AES3) format. This does ONLY apply to metadata, the actual audio sample data is always transmitted in the same way.

8.3.
AUX channel offset (DIP7...9)
When used in standalone mode (i.e. with AUX card), the AES3 is normally embedded in the AUX data stream from channel 1 to 16. Also, channels 1-16 of the audio stream coming from AUX are extracted to AES3.
Sometimes (i.e. in a MADI daisy-chain configuration) it is desired to map the AES3 stream to different channels, i.e. 17-32, 33-48 or 49-64. This is done using DIP switches 7 to 9.
This works only in standalone operation modes: "AES3 Direct <> AUX" and "AES3 via SRC <> AUX"
DIP Channel offset 0: AES3 will be mapped to AUX channels 1-16 7 8 Channel offset 16: AES3 will be mapped to AUX channels 17-32 7 8 Channel offset 32: AES3 will be mapped to AUX channels 33-48 7 8 Channel offset 48: AES3 will be mapped to AUX channels 49-64 7 8
8.4. FlexLink channel mapping (DIP3, 7..9)
The FlexLink interface can transmit 192x192 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.
Concat/Separate: Determines if AUX channels are seamlessly concatenated after AES3 A+B (commencing at channel 17), or if they are mapped to a separate block. "Concat" is useful e.g. with the AUX-AES3 card, to obtain a contiguous block total of 24x24 channels of AES3.
Lane Assignment (DIP7..9): Controls the mapping of the blocks to the FlexLink lanes. This is useful in double-flexiverter configurations, to make each data appear on the desired interface on the peer device.

FLX-AES3/SRC
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.
Make sure both ports "AES3 A" and "AES3 B" are set to the same pinout, matching the pinout of the loop-back cable.
Connect "AES3 A" to "AES3 B" using the loop-back 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-AES3SRC Unpack the firmware package FLX-AES3SRC-Firmware_x.y.zip Connect your PC via USB to the flexiverter Power ON the device Run the FLX-AES3_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
