Serial port (RS232 on DB9)
ES8in/ES8mic and ES8out dispose of a serial RS232 DB9 male port on the rear panel. Use this port to connect
any compatible device. For pinout allocation details, please refer to the figure and table above.
Note: The RS232 serial port requires specific software.
Setting the EtherSound channels
These two decimal rotary switches on the rear panel determine whether the
assignment of the EtherSound channels to the analog inputs or outputs of
ES8 is done locally or remotely by software control. The rotary switch on
the left is the “tens” position and the rotary switch on the right is the “ones”
position. Channels 1 to 64 are reserved for manual set-up, 0 and the
channels from 65 on set the device to remote configuration mode.
Manual set-up
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 using a small screwdriver (e. g. if you choose
channel no. 24 to be the first EtherSound channel, set the left switch to “2”, the right one to “4”). The other
channels will then be assigned subsequently (e. g. second channel = 25, third channel = 26 and so on…).
