KB3200 Series User’s Manual5 - 2
indicator for the “QWERTY” keyboard and the bottom left LED is the
Num-Lock indicator of the numerical keypad.
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
KB3200 series 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’s on
KB3200 series and PC or PS/2 keyboard change status accordingly. Yet,
if it is the “Caps Lock” key or the “Num Lock” key on KB3200 series
pressed, only the correspondent LED on KB3200 series will change
while the LED on PC or PS/2 keyboard remain unchanged.
C. 6 POSITION KEY-LOCK
The programmable keyboard has a six position key switch which
may also be programmed so that as the position of the key switch is
changed with a key, the key switch reports its own position (adjustable
inter-position time delays are programmed in). Further more, an enquiry
code from the host will cause the key switch to report its current
position.
This 6 position key switch effectively provides a multi-layer
capability to the keyboard. each position of the key can define separate
key sequence for each programmable key. This gives rise to the concept
of pages, so that KB3200 can be said to have 5 pages of 51 key
definitions per page and additional 2 programmable keys in numerical
keypad area. Therefor, there are in total 257 possible key definitions
programmable.
There are 4 keys supplied with each keyboard and the lock is so
designed that certain keys may only be turned to certain positions. This
architecture is similar to that found in many high end ECR systems, so it
is not surprising that the naming conventions have been borrowed as
well.
The keys are named: PRG, REG, Z, GT.
The switch positions are named: LP, L0, L1, L2, L3, L4. Among
these, the position L0 could also be referred to as “ ” which represents
