1. Introduction
Overview
This user manual describes the Avago HEDS-8937 pro-
grammer kit. The AEAT-6600-T16 magnetic encoder
programming kit features real-time monitoring and
programming of the 32-bit OTP memory within the
AEAT-6600-T16 magnetic encoder IC. The HEDS-8937
kit includes the IC interface hardware that is supported
by PC software.The IC interface hardware is a microcon-
troller system that links the AEAT-6600-T16 encoder to
the PC through a USB cable. This user manual describes
the hardware and PC software setup and gives instruc-
tions on PC software operation.

Figure 2. Components of the programmer kit
The USB cable (5) connects a PC USB port to the program-
mer (1).
Figure 3 shows the AEAT-6600-T16 programmer. The
red LED will light up when the programmer is powered
by connecting the programmer kit to the PC via the USB
cable. The green LED will blink when there is communi-
cation between the PC and encoder. The programmer’s
current consumption is less than 200 mA. The program-
mer incorporates a 100 mA current limiting circuit to
the IC adapter socket. If the current consumption for the
encoder being programmed or monitored exceeds 100
mA, the programmer will turn o the power supply to the
encoder. Figure 3. HEDS-8937 programmer top cover

3. Software Installation
The installation CD contains this user manual and the programmer application software. To install the application
software, browse to the software folder ‘Avago Magnetic Programmer’ and double-click the ‘Setup.exe’ icon in the
folder. The installation will run automatically. Figures 6, 7 and 8 illustrate the software installation.
Figure 6. Software installation startup screen. Click OK to start the installation.
Figure 7. Installation folder selection screen. Click ‘Change Directory’ to change the default installation folder.
Click the installation icon to continue.

Figure 8. Click 'Continue' to add the software under the default program group
The installation process will continue after the step shown in Figure 8, and nally a‘Setup successful’pop-up message
will indicate completion of the installation.
Locate the software by selecting: Start > All Program > Avago > Avago HEDS-8937 Application Kit (by default) or
other Start Group specied in the step shown in Figure 8.
To uninstall the software, open the Window’s Control Panel. Run ‘Add or Remove Program’ and locate ‘Avago
HEDS-8937 Application Kit’. Click 'Change / Remove", and follow the screen instructions to remove the software.

4. Software Application
4.1 OTP Programming
To run the application software, point to: Start > All Program > Avago > Avago HEDS-8937 Application Kit. After
selecting the software, the screen in Figure 9 will appear.
The software has three tabs: OTP Programming, Zero Position Programming and IC Monitoring. OTP programming
allows programming the OTP memory and zero position programming denes the zero position. The IC monitoring
tab displays the current encoder measurement.
Figure 9 shows the OTP programming tab. In the OTP programming tab, the software guides the OTP programming
step-by-step. When the ‘Detect IC’ button is clicked on the OTP programming tab, the software will locate the pro-
grammer and check for the presence of the AEAT-6600-T16 encoder.
Figure 9. OTP programming tab
Press this button to link the
software to the programmer.
OTP register values are available once encoder IC
presence is detected. The current SSI reading and
equivalent mechanical degree reading will also be
shown here.
Select OTP programming, Zero Position
Programming and IC Monitoring.

4.2 IC Detected
After the ‘Detect IC’ button is clicked and IC presence is detected, the screen in Figure 10 appears.

Select either one of the
programming modes
8
The contents of the OTP memory are displayed in the‘Conguration Bit in OTP’frame. The indicated OTP memory is in
binary followed by the equivalent hexadecimal value.The symbol‘/’separates the binary and hexadecimal values. The
SSI ABS measurement is the position value captured when the ‘Detect IC’ button is clicked. ‘Mech Degree’ indicates
the equivalent mechanical angle calculated from the SSI ABS value.
If the encoder is detected, the ‘Select Programming Method’ frame appears. Select one of the output modes. This
selection enables the OTP conguration registers to be congured.
If ‘Absolute Output Only” is selected, only the ‘Absolute Resolution Setting’, ‘PWM Period Selection’, ‘PWM Output
Enable’, ‘Output Direction Invert’ and ‘Speed Mode’ selection options are enabled. The ‘Write OTP’ button will be
visible as well.

Figure 13. Incremental output only setting
If ‘Incremental Output Only’ is selected, the ‘UVW Pole Pair Setting’ / ‘Index Pulse Width’, ‘Incremental Resolution
Setting’, ‘Zero Position Setting’, ‘Index Output logic’, ‘Incremental Mode’ and ‘Incremental Output Enable’ selection
options are enabled. The ‘Write OTP’ button will be visible as well.

If ‘Both Absolute and Incremental Output’ is selected, all the OTP conguration settings will be enabled (except the
Zero Position Setting). A pop-up message box, as shown in Figure 14 will appear.
