PS2PROX KEY OVERRIDE OVERVIEW

The PS2PROX(-tended) is a small adapter which converts a standard PC keyboard into an RS232 output device. It is an eXtended version of the PS2PRO with more programmable keys and allowing longer strings. It can be used as delivered from the factory to output standard serial KeyCap characters associated with each keypress, or the user can reprogram keyboard keys to output alternate characters, or even strings of up to 10 characters for a single keypress.
PS2PROX can be programmed to output user-defined characters/strings for up to 93 keyboard keys, and each associated output string can be from 0 to 10 characters long. Pressing one key can then generate an output of "Hello!" for instance. Strings are created within the PS2PROX Configuration Program and associated with a keyboard key, then downloaded to the PS2PROX all from within this program. When those keys are then pressed, PS2PROX outputs the user's custom strings instead of the default KeyCap characters. These user settings are nonvolatile so they remain in effect indefinitely with or without power applied -- until the string is altered or removed by the user. If a key override is removed, the key output reverts to the factory default character output. Keyboard keys can be effectively disabled by entering a Keyboard Key to override and leaving the associated output string empty so that the key produces no output.
Custom strings can be defined for any of the keys on a standard (English) 102-key keyboard. All keys including the F1 thru F12 Function keys , all the QWERTY ASCII keys, all the numeric keypad keys, all the arrow keys and even the Insert/Pgup/DN/Delete etc keys can be overridden. . Not only can your output strings include standard printable ASCII characters, but can include non-printable 'control characters', or 8-bit characters which lie high beyond the range of the standard ASCII set. To output a hexadecimal 'character' that has no equivalent ASCII value you enter hexadecimal format {E9} for instance. Notice that within the brackets there must be a maximum of 2 hexadecimal characters only with no radix identifier. This is an 8-bit byte/character that has no ASCII equivalent. Even ASCII characters can be entered using their hexacedimal equivalents, so a space character which is a printable ASCII character for instance can be entered by pressing the space bar, or as {20} which may make strings more readable especially if your string contains 2 or more consecutive spaces.
  • Step 1  Select a Maximum Override String Length. This will also define how many keys can be overridden.
  • Step 2  Enter a Keyboard Key to Override. Click the cursor in a Keyboard Key field and press a keyboard key (on PC's keyboard).
  • Step 3  Enter an associated Override String up to the maximum number of characters allowed per your selection.
  • Step 4  Repeat entering Keyboard Keys to override, and associated strings as needed. Leave unneeded fields empty.
  • Step 5  Press the 'Send Key Outputs' button to load these into your COM port attached (and powered) PS2PROX device.
  • Step 6  Optionally SAVE these entries to a file for later use.
  • Step 7  To remove ALL key overrides and return to defaults, click the Clear All menu item, and press 'Send Key Outputs'
