The top left LED is for stand-by indication, the top right LED is the power-on
indicator and the bottom right LED is the Cap-Lock indicator for the “QWERTY”
keyboard. For the KB136 manufactured after year 1999, another LED at the bottom
left is added to indicate Num-Lock status of the numerical keypad as shown in the
right in Fig. 6-2.
The two top LED’s work exactly in the way the host system (e.g. PST1000 or
PST6000 series) defines. In other words, the description in the user’s manual of the
system applies for these two LED’s.
For the “Caps Lock” or “Num Lock” LED at the bottom, the function as of a
normal standard PC or PS/2 keyboard applies if the KB136 is operating alone without
an external PC or PS/2 keyboard connected. When an external PC or PS/2 keyboard is
connected, pressing the “Caps Lock” key or the “Num Lock” key on the PC or PS/2
keyboard will have both the correspondent LED on KB136 and PC or PS/2 keyboard
change status accordingly. Yet, if it is the “Caps Lock” key or the “Num Lock” key
on KB136 pressed, only the correspondent LED on KB136 will change while the
LED on PC or PS/2 keyboard remain unchanged.
6 POSITION KEY-LOCK
The 6 position electronic key-lock in KB136 is identical to the one in KB112.
