Hardware installation
Embedding the KeyGrabber Module inside a PS/2 or USB keyboard is a one-time process
and has to be done by the user. Data typed on this keyboard will be logged by the module
whenever the keyboard is powered. The same keyboard must be used to retrieve recorded
data afterwards. It is the user’s responsibility for connecting the KeyGrabber Module correctly,
following the detailed guide below.
Disclaimer
The manufacturer and/or seller of the KeyGrabber Module will take no responsibility for
the following events:
•damage to the KeyGrabber Module, keyboard, or computer caused by incorrect
installation or misuse
•loss of warranty for the keyboard or computer
•any other damage or harm caused by not following the installation instructions
•failure of user installation
Please note that the instructions and images below are provided only as an example. The
internal keyboard component and cable layout may vary for different keyboard manufacturers.

Overview
The KeyGrabber Module has to be located between the keyboard controller (inside the
keyboard) and the keyboard PS/2 or USB cable. This requires cutting the four main USB
signal lines (VCC, GND, D+, D-) or PS/2 signal lines (VCC, GND, CLK, DATA) and
connecting them to the KeyGrabber Module from both sides.

Checklist
Before starting, make sure you have everything that’s
necessary to successfully mount the KeyGrabber Module
inside the keyboard. First of all, disconnect the keyboard
from the computer, undo the screws, and open the keyboard
housing. Make sure there is enough space inside the keyboard
for the KeyGrabber Module.
Then, make sure you have all the parts and tools necessary to
perform the installation process:
•KeyGrabber Module circuit miniboard
•Two 4-pin 0.1" connectors (supplied with the module)
•Short-circuit tester or ohmmeter (present in most
multimeters)
•Pliers or crimp tool
•Glue or resin

Preparing the keyboard
A standard USB or PS/2 keyboard is connected with the computer using 2 power lines, and 2
signal lines. The KeyGrabber Module should connect to these lines both on the PS side, and
on the keyboard side. In some cases two additional unused lines and shielding are present
(leave these unconnected).

Identify the connector at the keyboard controller first. Use the short-circuit tester to determine
which wires are connected to the pins at the keyboard USB or PS/2 plug. An example is
shown on the picture below. Note, that only the pins at the USB or PS/2 connector are
determined. The pins inside the keyboard are unknown, and must be examined with the
short-circuit tester.
Note down the cable configuration, identifying the wires by their colors. Only the four main
signal lines are significant. The NC lines and shielding may be ignored.

Preparing the connectors
Find a spot for mounting the KeyGrabber Module inside the keyboard. Then, cut the four main
signal wires in a way which will allow connecting to the module from both sides. It may be
necessary to peel the cable coating, as shown on the image below. If the shielding and NC
lines are present, there is no need to cut them.
Prepare the wire tips. Crimp the provided connector sockets over the wire tips with the pliers
or crimp tool.
Finally, assemble the black 0.1” connectors, inserting the sockets into the casing. The
connector pinout must match the module pinout on both sides, as shown on the picture
below.
