Confi guring the KE18 Jumpers
The KE18 is designed to be easy to use. There are 3 jumpers located on
the board which allow for selection of various modes. These jumpers
must be set before using the product.
Jumper 1
This jumper selects the repeat function of the inputs on the KE18’s
I/O header.
With this jumper in place, inputs will send a single keystroke to the PC
when activated regardless of the length of time they are held on.
When this jumper is open, inputs on the KE18’s I/O header will repeat
their defi ned keystroke for the duration the input is held active or until
another input is activated.
Jumper 2
This jumper controls the scanning mode for the I/O header on the
KE18.
If this jumper is in place, the KE18 will scan the I/O header as 18
individual inputs (pins “A” through “R”). Keystrokes to the PC are
activated in the 18 input mode by making a connection between an
input pin and one of the logic ground pins (“Gnd”), provided at each
end of the I/O header.
With this jumper open, the KE18 scans the I/O header as a 9 Column
by 9 Row matrix. In this mode, keystrokes to the PC are generated by
connecting a switch such that one Row pin (“J” through “R”) and one
Column pin (“A” through “I”) are shorted together when the switch is
activated.
NOTE:
See the Keycode Lookup Tables on page 6 for keystrokes
available in each of these modes.
