ES220 & ES220-L
Ethernet Audio Bridges
11
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. connected to a
switch)
Audio
The pinout of the connector is depicted on the label on top of the device:
These balanced inputs/outputs are can be used with unbalanced audio sources
and destinations: just wire both cold pin and ground pin on ES220(-L) to the
ground of the unbalanced signal and the hot pin to the signal. Note that in
this case the unbalanced output signal is multiplied by two (+6 dB), it is thus
necessary to reduce the output gain (-6 dB) in order not to saturate the signal.
By default, the nominal input/output level of an ES220 or an ES220-L is
+4 dBu.
On ES220(-L) the nominal input level can be set to +10 dBu via internal
jumpers (
for more details see appendix E: Setting the internal jumpers
).
The values of the nominal output level can be adjusted for each channel
through management software and stored in the ES8out device.
GPIO
ES220 and ES220-L are shipped with four GPIs and four GPOs on a 15-pin
Sub-D connector. For details see Appendix D.
Note:
the GPIO port is managed by configuration software only.
Remote set-up by means of configuration software
To manage the device remotely using configuration software, the rotary
switches must be set manually to any value ranging between 65 and 99
(factory setting). Use of the configuration software allows for advanced
channel allocation; for software details, please refer to the online help file.
ES220 and ES220-L can be managed by Digigram’s configuration software
EScontrol. Please download the required software indicated hereafter from
www.digigram.com
,
Downloads-Applications, EScontrol
and install it in this
order: the EtherSound driver (
EtherSound Runtime
), the specific DLLs to
manage Digigram products (
ES Digigram Products Runtime
), and the
EScontrol
application.
Note:
This operation is only necessary if software control is needed.
