the Word clock input
If an AQONDA is "Primary Master", it can be synchronized on its internal oscillator, or on the signal present
on the Word Clock input.
If the equipment is not in "Primary Master" mode, it can be synchronized on the clock provided by the
"Primary Master" through the network, or on the signal on its Word Clock input. In this last case, it has to be
made sure that the reference clock of the "Primary Master" and the Word Clock signal provided to the device
are synchronous.
These elements can be parameterized through the EScontrol configuration software, available on our web site.
Audio
The pinout used on the XLRs is standard: pin 1 carries the signal ground, pin 2 carries the positive signal
("hot", +) and pin 3 carries the negative signal ("cold", -).
GPIOs
AQONDA 8 et AQONDA 16 are delivered with eight GPIs and eight GPOs on terminal block connectors; the
counterparts are provided. For details see Appendix A.
Serial port (RS232/422 on DB9)
AQONDA 8 and AQONDA 16 feature an RS232/422 serial port on male DB9 on the back panel. Use this port
to connect any compatible device. For the specifications of the serial port, please refer to appendix B of this
manual).
Note:
The serial port is not operational yet.
Connecting a computer to configure the device and the manage an EtherSound
network
To connect a PC directly to an AQONDA, it must be equipped with a network card. Use an Ethernet cable to
connect the network card to the "DATA/CTRL" port of the AQONDA.
It is also possible to connect to the device through a conventional Ethernet network.
Two software applications allow for configuration of an AQONDA and control of an EtherSound network:
EScontrol, available on the Digigram web site, and ESmonitor by Auvitran. For details on their use, please
refer to their on-line help.
Important: if the device is not Primary Master, the DATA/CTRL port of the AQONDA can only be used to
control the network from a PC, if all devices on the network operate with an EtherSound
technology version (kernel) higher than 3.0. If this is not the case, only the DATA/CTRL port or the
IN port of the Primary Master can be used for this purpose.
Firmware update
Digigram may decide to publish updates of the embedded firmware. It may then become necessary to upgrade
your devices. In this case, please refer to the documents delivered with the firmware update tool. These
updates, as well as the required software tool, are available on the Digigram web site.
