The format for entering keystrokes and keystrokes combinations is as described in the following table.
Key code Definition
+ Generate a keystroke message with the following key being pressed.
- Generate a keystroke message with the following key being released.
+- Generate a keystroke message with the following key being pressed and released.
* Wait 250 milliseconds before initiating the next keystroke message in the keystroke
combination. If the key code is followed by a number, wait as many milliseconds as the
number specifies. This is particularly helpful when sending switch commands to chained
switches, and a delay is needed to wait for a higher level switch to complete switching, before
sending a switch command to a lower level switch,
Table 1. UL2-DVI Keystroke Modifiers
The UL2-DVI requires abbreviations it recognizes for the keys on the keyboard. These are described in
Appendix C. These abbreviations are used in the Keyboard Control screen to indicate the keys to be pressed
and released.
The UL2-DVI assumes that any key whose key release has not been specified in the keystroke sequence with
the “-“ key code will be automatically released when the sequence is completed. It is not necessary to explicitly
specify the key release at the end of a combination.
Examples for some keystroke combinations are given below.
 +Ctrl+Alt+Del means that the Ctrl, Alt and Del keys are to be simultaneously pressed to generate the
Ctrl+Alt+Del command. It is not necessary to enter “-Ctrl-Alt-Del” since all keys are understood to be
released at the end of the sequence.
 The keystroke combination “Ctrl+Alt+12” will be entered either as “+Ctrl+Alt+1-1+2” or “+Ctrl+Alt+-1+2”.
The “1” key has to be released before the “2” key is pressed. However, the Ctrl and Alt keys should remain
pressed until the combination is complete.
Note that there are no spaces between the individual components of the keystroke combinations. A space
between the components would cause the combination to be unrecognized by the UL2-DVI. If a space is
required in the combination, it can be introduced by inserting “+Space” into the combination at the appropriate
location.
To use the Keyboard Control screen, enter up to eight different keystroke sequences into the fields provided.
The first three fields are pre-populated with the combinations for the Ctrl+Alt+Del, Alt+Tab and Win keystroke
combinations. These keystroke combinations are the most commonly used since they are trapped by the
connecting computer when pressed from the keyboard, and not transmitted to the UL2-DVI. However, they can
be removed if desired to accommodate other keystroke combinations. To send one of the stored keystroke
combinations to the UL2-DVI, press the Send button next to it. Multiple keystroke combinations can be sent to
the UL2-DVI by pressing the Send button for each of them.
