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 it 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.
4.8.1.13.3.1 User Interface Commands
The UF commands are used to assign commands to the user interface functions. For example, the
command UF07,00:"S1V" assigns user interface function 07 selection number 00 to perform the command
S1V (toggle the visibility of Text Field 1). 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 semicolon delimiter. For example
UF07,00:"S1V;S2V" will toggle the visibility of Text Field 1 and 2.
Another version of the UF command supports appending additional commands to a selection that already
has a command assigned. The command UF07:00+"S3V", executed after the previous example, adds the
command S3V to the previous commands.
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.

ONFIGURATION
The DX-2200-TI 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 restores the default
DIP and Toggle switch settings, but does not clear any user interface functions that the user has configured.

ECOMMENDATIONS FOR

ONFIGURATION
Assign either one set of DIP switches, or one toggle switch to a user interface function. Assigning more than
one toggle switch, or both DIP and toggle switches to the same function will usually have undesirable
results.
Don’t assign Toggle Commands to DIP switches. For example, don’t assign ‘S1V’ to a DIP switch. Use ‘S1S’
and ‘S1H’ instead to show or hide a text field.

User Interface commands
USn:ff Assign DIP switch number n to user interface function ff for all operating modes.
n must be one digit and ff must be two digits.
USnMmm:ff
Assign DIP switch number n to user interface function ff for operating mode mm
only. The assignments for other modes remain unchanged.
ff and mm must both be two digits.
