D21m System
6.3.11 EtherSound
®
Card ( and ) (Details: www.digigram.com)
The EtherSound
®
card allows connecting the D21m I/O System to an Ether-
Sound
®
network. Towards the D21m system, it acts similar to a MADI card
combined with a GPIO card. The number of audio channels used can be
configured with DIP switches. The included, virtual GPIO card allows, e.g.,
routing a GPO of the mixing console to the GPO of a distant EtherSound
®
device on the network. Configuration of the EtherSound
®
network is per-
formed either through the ETH CTRL connector or from a remote location
on the EtherSound
®
network, e.g. using the EtherSound
®
EScontrol software.
The EtherSound
®
card works with EtherSound
®
ES-Giga System Transport
networks or with EtherSound
®
ES-100 Audio Transport networks. The operat-
ing mode of the card (ES-100 or ES-Giga) is selected by setting jumper J22
(see opposite page). The selected mode will be displayed on the front panel
LEDs.
The audio clock of the EtherSound
®
network must be synchronous with the
D21m I/O system’s audio clock. This is ensured either by using the Ether-
Sound
®
card as clock source of the EtherSound
®
network, or by feeding the
device that is actually the EtherSound
®
network clock source with a word
clock synchronous with the D21m I/O system’s audio clock.
This card works at sampling rates of 44.1 or 48 kHz (88.2/96 kHz ready).
Current consumption (5 V) 750 mA max.
Operating temperature 0-40 °C

audio inputs on the Ethersound network, and vice versa.
