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.

KeyGrabber Module

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

KeyGrabber Module

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).

Disconnect the keyboard from the computer, undo the screws, and open the keyboard

housing. You should see the keyboard cable connected to the keyboard controller.

KeyGrabber Module

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.

KeyGrabber Module

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.
