System
This window displays the firmware version
currently running on the DC-One.
RS232 Port
An RS 232 (DB-9 or ‘D-Sub’) connection
is provided on the back panel to link to
another DC-One to enable Master/Slave
operation. Use the <SELECT> key to
navigate to the MODE parameter and use
the up/down VALUE arrows to choose
between RS232 and Contacts.
Contacts allow control
messages to select individual
presets (per pin 1-9) using a
remote device. The additional
CONTACTS parameter is used
as a display only and
corresponds to the binary
values of individual pins, ie -
on/off.
