You can use a serial device connected to your system that implements and exposes the packet interface of the AMBE3000 chip. This can be for example a ThumbDV USB dongle. You may also connect to an AMBE server instance over the network. This is supported via the [AMBE feature](../../feature/ambe/readme.md).
|
||||
|
||||
DV serial devices are supported using the [SerialDV](https://github.com/f4exb/serialDV) library that is a mandatory requirement. Therefore you have to compile and install it in your system. Please refer to this project Readme.md to compile and install SerialDV. f you install it in a custom location say `/opt/install/serialdv` you will need to add this define to the cmake command: `-DSERIALDV_DIR=/opt/install/serialdv`
|
||||
|
||||
To effectively use serial DV devices for AMBE decoding you will have to add at least one device to the list of AMBE devices in use using the `AMBE devices control` dialog opened with the `AMBE` option in the `Preferences` menu. The list of devices is saved in the program preferences so that they are persistent across program stop/start. However if the device name or server address changes in between the corresponding reference will be lost.
|
||||
|
||||
Although such serial devices work with a serial interface at 400 kb in practice maybe for other reasons they are capable of handling only one conversation at a time. The software will allocate the device dynamically to a conversation with an inactivity timeout of 1 second so that conversations do not get interrupted constantly making the audio output too choppy. In practice you will have to have as many devices connected to your system as the number of conversations you would like to be handled in parallel.
|
||||
|
||||
Note also that hardware serial devices are not supported in Windows because of trouble with COM port support (contributors welcome!).
|
||||
|
||||
If no AMBE devices or servers are activated with the `AMBE devices control` AMBE decoding will take place with Mbelib. Possible copyright issues apart (see next) the audio quality with the DVSI AMBE chip is much better.
|
||||
|
||||

|
||||
⚠ With kernel 4.4.52 and maybe other 4.4 versions the default for FTDI devices (that is in the ftdi_sio kernel module) is not to set it as low latency. This results in the ThumbDV dongle not working anymore because its response is too slow to sustain the normal AMBE packets flow. The solution is to force low latency by changing the variable for your device (ex: /dev/ttyUSB0) as follows:
|
||||
|
||||
`echo 1 | sudo tee /sys/bus/usb-serial/devices/ttyUSB0/latency_timer` or `sudo setserial /dev/ttyUSB0 low_latency`
|
||||
|
||||
Newer kernels do not seem to have this issue.

If no AMBE features are active or the AMBE support is not engaged (B.19) AMBE decoding will take place with Mbelib. Possible copyright issues apart (see next) the audio quality with the DVSI AMBE chip is much better.

When clicking on the AMBE submenu a dialog opens to let you specify physical AMBE devices to decode AMBE frames produced by digital voice signals (using DSD decoder plugin).
|

|
||||
|
||||
|
||||
<h4>2.3.1: AMBE server address and port or direct input</h4>
|
||||
|
||||
Use this freeflow text input box to specify either the address and port of an AMBE server in the form: <IPv4 address>:<port> or any directly attached physical device address like a COM port on Windows.
|
||||
|
||||
<h4>2.3.2: Import above address or device</h4>
|
||||
|
||||
Import the address or device specified in (1) into the list of used devices. The system will try to open the device or contact the server and will add it to the list only if successful.

||||
|
||||
<h4>2.3.3: Remove in use device or address</h4>
|
||||
|
||||
When a device or address is selected in the in use list (6) push this button to remove it from the list. The corresponding resources will be released.
|
||||
|
||||
<h4>2.3.4: Refresh in use list</h4>
|
||||

Checks the list of devices or addresses currently in use and update the in use list (6).
|
||||
|
||||
<h4>2.3.5: Empty in use list</h4>
|
||||
|
||||
Removes all devices or addresses in use. The in use list (6) is cleared consequently. This removes all AMBE devices related resources attached to the current instance of the SDRangel program. Therefore consecutive AMBE frames decoding will be handled by the mbelib library if available or no audio will be output.
