The KMX-LCD board
will not work on its own You need to have both a KeyMaker
and a KMX-LCD to have a working unit
You do NOT receive a
KeyMaker board when you buy a KMX-LCD, you will also need to buy either a KMX1
or KMX2 board in order to
have a working unit.
There is no point to purchasing
KMX-LCD on its own unless you already own or intend to buy a
KeyMaker KMX1 or KMX2
The KMX-LCD board plugs in on top
of ANY of the existing KeyMaker boards KM7, KM8, KM9, KM9A, KMX1 or KMX2 all of which

No need for a second PC AND you are not
limited to using only the Zap SVP button when you operate without a second
Nearly all functions that are available when using a
second PC are available
when using the KMX-LCD.

ones which require saving a file or retrieving a file from a PC.
leave the KMX-LCD attached even when you have the KeyMaker plugged into a
second PC as it does provide useful display of Status closer to where you
are working on the TP.
You do not need to make a separate GND
connection when the locked ThinkPad is supplying power to the KeyMaker + KMX-LCD
combination. The USB cable connected to the LOCKED TP provides the required GND
connection to the TP.
This makes unlocking a ThinkPad a LOT
You only have 2 leads to
connect SDA and SCL and together with the variable count down delay
[first available on KMX1] displayed on
the LCD you do NOT need a second person to help press the ZAP SVP button or
operate the second PC's keyboard.
Using the Joystick you can scroll through
the KeyMaker menus, select different KeyMaker functions, start or cancel operations etc.
You can adjust the KMX-LCD Contrast using
the Joystick when KMX-LCD is attached to KMX1 or later KeyMaker models.
You see useful status feedback about the
operation you are performing as well as the result being successful or not.
