the KE-USB36.
Note: The KE-USB36 allows up to 6 keystroke inputs to be
activated simultaneously. This limitation does not include inputs
defined as Shift keys, Ctrl keys, Alt keys, Win GUI keys, or Mouse
Left, Middle, or Right Buttons.
Keyboard Status Light Signals
Keyboard status light drive is available with the KE-USB36. The unit
provides a 6 pin header for connection of the Num Lock, Caps
Lock, and Scroll Lock
status LEDs. As shown
below, the Anode and
Cathode connections for
these diodes are labeled
on the board near the 6
pin LED header.
As with the input header, this LED header is .100" spaced pins,
which is suitable for a variety of connectors. Soldering to the pins
is also an acceptable way to attach wires for connection to your
LEDs.

Status LED Header

The KE-USB36 will drive on LED
directly from each Anode/Cathode
pair of wires. At 5 volts, the drive
current is approximately 10 ma
for each LED. The KE-USB36 has
current limiting resistors on the unit,
so connection to the user's LED may
be made directly.
