D i g i g r a m Thank you for purchasing Digigram EtherSound ES220(-L)! EtherSound ES220 and ES220-L are Digigram products incorporating the EtherSound technology. They allow to easily and economically insert or extract two digital audio channels (2 + 2 in the case of ES220) from an EtherSound network using standard Ethernet components (cables CAT5 and switches).
ES220 & ES220-L Ethernet Audio Bridges IMPORTANT NOTICE This card has been tested and found to comply with the following standards: Electrical safety: Elecromagnetic compatibility: Europe: EN60950, 3rd edition European Directive 73/23/CEE “Low Voltage Directive” International: EN60950, 3rd edition Europe : EN55022:1998 + A1:2000, Class B / EN55024: 1998 + A1:2001 European Directive 89/336/CEE on electromagnetic compatibility International: CISPR22:1997 + A1:2000 CLASS B United States: FCC Rules-Part 15-C

Audio connectors On ES220, a Sub-D 15 connector is used to input two balanced analog signals and to output two balanced analog signals. On ES220-L, only one of these two functions is accessible depending on the configuration selected (for connector pinout see appendix C). 2.
ES220 & ES220-L Ethernet Audio Bridges INSTALLATION Before mounting devices in a rack… Internal settings Note: These operations require opening of the cabinet and shall be done by qualified personnel only. Setting the EtherSound channels (ES220 and ES220-L) Four decimal rotary switches on the EtherSound board inside the device determine whether the assignment of the EtherSound channels to the inputs or outputs of ES220(-L) is done locally or remotely by configuration software.
D i g i g r a m Network The network connections are established via two NeutrikTM EtherConTM RJ45 receptacles. Connection is very easy: use the connector labeled “IN“ to input the EtherSound stream, the connector labeled “OUT“ to send the EtherSound stream to other devices. The NeutrikTM EtherConTM RJ45 provide secure connection through a latching system. To disconnect the cable from the device, press the latch, then withdraw the cable while maintaining the latch pushed.
ES220 & ES220-L Ethernet Audio Bridges Connecting a computer to manage the EtherSound network To connect a PC directly to an ES220(-L), it must be equipped with a network card. Use a crossover Ethernet cable to connect the network card to the “IN” port of the Primary Master. You can also access the Primary Master through a conventional Ethernet network; in this case, use a standard Ethernet cable (e. g.
D i g i g r a m ES220 and ES220-L may also be managed through configuration software edited by Digigram development partners. To uninstall the software go to Add/Remove programs in the Windows Control Panel. Firmware update Digigram may decide to publish firmware updates. It may then become necessary to upgrade your devices. In this case please refer to the respective documentation provided with the firmware upgrade tool.

D i g i g r a m APPENDIX C: AUDIO CONNECTOR On ES220, a Sub-D 15 connector is used to input two balanced analog signals and to output two balanced analog signals. On ES220-L, only one of these two functions is accessible depending on the configuration selected (for connector pinout see appendix D).
ES220 & ES220-L Ethernet Audio Bridges APPENDIX D: GPIO CONNECTOR ES220 and ES220-L have four TTL 5 V compatible GPIs and four open collector GPOs. GPIs allow sending commands to the EtherSound configuration software, GPOs can be used by the EtherSound configuration software for remote control of external devices. General Purpose Inputs (GPIs) Schematic diagrams show the particular design for each GPI. The GPI status can be either 1 (=ON) or 0 (=OFF).
