SIN/COS INTERFACE ADAPTER TO PC-USB 2.0
SYSTEM EXAMPLE
Rev A2, Page 6/9
iC-tools SC can be used to transfer position data of a
magnetic interpolator (e.g. iC-MH8) to a windows pc.
The iC-MH8 offers analog pins to grip the differential
sine and cosine signals generated by the built-in Hall
sensor. These pins must be connected to the iC-tools
SC in the following manner.
shaft is used to generate the magnetic field. The mo-
tor power is also reclaimed from the iC-tools SC.
When connected to a windows pc, the iC-tools SC is
automatically installed to the operation system. There
is no need for any hardware drivers! After the iC-tool
SC is detected by your computer, the iC-tools SC soft-
ware can be downloaded at the iC-tools internet page.
Setup.exe starts the easy installation process, which
includes all information nedded.
Figure 5: Connection of System Components
First, the ground pins of the iC-tools SC should be con-
nected to the reference potential of the iC-MH8 chip.
To find the correct pins, there is a short connector de-
scription at the bottom of the iC-tools SC. The field
power supply (5V) can be used to power the iC-MH8.
Thus, there is no need for any another power sources
besides USB. As Figure 5 shows, the iC-MH8 outputs
PSOUT, NSOUT, PCOUT and NCOUT have to be con-
nected to the corresponding pins at the iC-tools SC
connector. If there is no need for the index signal, IDX-
and IDX+ can be put to ground. The general I/O pins
can be left floating as well.
Figure 7: Main Window
When the installer is finished, the program can be
started by clicking the iC-tools SC logo in the windows
start menu. The iC-tools SC must be plugged into the
USB port now. The iC-tools main window appears as
shown in Figure 7. The iC-tools SC can be renamed
by clicking into the ID label at the bottom. So, it is pos-
sible to choose a meaningful expression for that chan-
nel. This function helps to find a specific device, when
using multiple iC-tools SC at once. Before starting an-
alyzing sensor signals, the device has to be setup cor-
rectly. This can be done by clicking onto the arrow next
to the ID label. The appearing system window allows
to change the Periods per revolution. For the MH8
demoboard, it has to be changed to 1, because the
magnet has one terminal pair only. The Millimeter per
period configuration does not have to be altered. It
is only important for systems with linear sensor tech-
nology. The other configuration options can be left un-
changed as well.

Figure 8: Increments
Figure 6 shows a real world example of the iC-tools
SC. As described above, the iC-tools SC is connected
to the differential analog interface of a iC-MH8 demo
board. A standard 14 pin ribbon cable is used to con-
nect the two devices. A motor with a magnet at the
First, the display window should be opened as shown
in Figure 8 by clicking on the tool button B in Figure
7. The default configuration shows the incremental po-
sition. If the motor is running and everything is setup
correctly, the increment should increase. If the value
