factory default configuration, all user interface functions are unused and have no
commands assigned to them.
The switches that control a user interface function can be either one or more DIP
switches, or a toggle switch.
If DIP switches have been assigned, then the value set on the switches
determines the selection. Each switch that has been assigned becomes one bit of
the selection value, with the least significant bit being the switch with the lowest
number (as marked on the DIP switch component). When a switch is OFF, the bit
value is 0. When the switch is on, the bit value is 1.
If a toggle switch has been assigned, then the switch increments the selection
each time is is toggled, until a selection is found with no command assigned, or
the maximum number of selections has been reached. This indicates the end of
the toggle switch function loop and the selection is reset to 0.
The UF commands are used to assign commands to the user interface functions.
For example, the command UF07,00:”M2” assigned user interface function 07,
selection number 00 to have the command M2 (set the mode of the DX-2200 to
PiP). Any previous command assignment for this user interface function and
selection is erased by this command.
The command string that is being assigned is always enclosed with quotation
marks. More than one command can be assigned in the above command using a
sem
icolon delimiter. For example UF07,00:”M2;P1” will set the mode to PiP and
also set the PiP position to predefined position P1.
Another version of the UF command supports appending additional commands to
a selection that already has a command assigned. The command
UF07:00+”PS01”, executed after the previous example, adds the command PS01
to set the PiP size to 1/16
th
of the screen width.
Executing UF07,00:”” clears any command that was previously assigned to
Selection 00 of user function 07.
When executing
the UF commands, the command response (either ‘+’ or ‘-‘)
indicates only that the syntax of the UF command was accepted. It does not
indicate the command string being assigned to the user interface function is
correct. Commands can be tested by executing them prior to assigning them to
user interface functions.

The DX-2200 provides commands to clear the user functions and restore the
default switch settings. All selections of a user functions can be cleared using the
UFnnC command where nn is the user function number. All user functions can be
cleared with the UFC command. The UR command restored the default DIP and
Toggle switch settings, but does not clear any user interface functions that the
user has configured.
