(For the position of the rotary switches on the board see appendix A)
The two rotary switches on the left (Audio IN) allow encoding the channels to
transport the audio coming from the analog inputs. The two rotary switches
on the right (Audio OUT) allow encoding the channels to be played on the
analog outputs. In every pair, the rotary switch on the left is the “tens“
position and the rotary switch on the right is the “ones“ position. Channels 01
to 64 are reserved for manual set-up, channels 65 to 99 set the device remote
configuration.
Software configuration mode is indicated by a lightened red
electroluminescent diode.
In position 00 of the rotary switches the audio is “
Mute
”: in input mode no
EtherSound channel inserted, in output mode no sound played.
To manually set the EtherSound channels to be used by the device, configure
the number of the EtherSound channel to be assigned to the first analog input
or output by means of a small screw-driver.
Example: to assign channel no. 24 the first EtherSound channel, set the
left switch to “2”, the right one to “4”.
The other channel is assigned subsequently (In our example: 25).
The factory preset is 90, thus the control is done remotely by software.
Note:
On ES220-L, only one pair of rotary switches is active, depending on
the selected configuration: inputs OR outputs.
Light Emitting Diode (3)
This red LED indicates whether the EtherSound channel selection is done
manually by hardware (LED off) or remotely by software (LED on).
