MAX6960 Evaluation Kit/Evaluation System
The MAX6960 evaluation kit (EV kit) provides a proven
design to evaluate the MAX6960 8 x 8 graphic LED tile
display driver. The EV kit board contains four MAX6960
LED display drivers, four 2.4in 8 x 8 bicolor LED tiles, a
4MHz oscillator, and logic buffers. Each MAX6960 EV
kit can be cascaded to support up to a total of 20
MAX6960 devices. The EV kit also includes Windows®
98SE/2000/XP-compatible software, which provides a
simple graphical user interface (GUI) for exercising the
MAX6960’s features.
The MAX6960 evaluation system (EV system) consists
of a MAX6960 EV kit and a companion Maxim
CMODUSB serial interface board. The Maxim
CMODUSB serial interface board allows an IBMcompatible PC to use its USB port to emulate a serial
interface that is compatible with the MAX6960. Order
the MAX6960EVCMODU for a complete PC-based evaluation of the MAX6960. Order the MAX6960EVKIT if you
already have a MAX6960 compatible serial interface.
The EV kit includes a preinstalled MAX6960ATH.

6) Connect the included USB cable from the PC to the
CMODUSB board. A Building Driver Database window pops up in addition to a New Hardware Found
message. If you do not see any window that is similar
to the one described above after 30 seconds, remove
the USB cable from the CMODUSB board and reconnect it again. Administrator privileges are required to
install the USB device driver on Windows 2000 and
XP. Refer to the document Troubleshooting USB.PDF
included with the software for more information.
7) Follow the directions of the Add New Hardware
Wizard to install the USB device driver. Choose the
Search for the best driver for your device option.
Specify the location of the device driver to be
C:\Program Files\MAX6960 using the Browse button.
8) Start the MAX6960 EV kit software by opening its
icon in the Windows Start menu | Programs | Maxim
MAX6960 Evaluation Kit. If the 16-color demo mode
is visible, then quick start is complete.
Loading Scripts (Optional)
1) Press the Load 8-bit Write Script button on the 8
and 16-bit addr modes tab.
2) Load the script file 1bit_step1_box.cm2 located in
the C:\Program Files\MAX6960 directory.
3) Press the Run 8-bit Write Script (16bytes) button in
the 8-bit Write Script window.
4) Press the Load Next Script button and load the
script file 1bit_step2_box.cm2 located in the
C:\Program Files\MAX6960 directory.
5) Press the Run 8-bit Write Script (16bytes) button in
the 8-bit Write Script window.
Detailed Description of Software
The evaluation software’s main window shown in Figure
1 displays tabs for 8-bit, 16-bit, and 24-bit addressing
modes as well as individual tabs for each register in the
MAX6960’s register address map (0x00 through 0x0F).
Table 1 describes the controls that are always present
on the evaluation software’s main window.
The 8 and 16-bit addr modes tab, shown in Figure 1,
allows the user to execute 8-bit and 16-bit address mode
operations. The 8-bit address mode is the quickest
method of updating a plane of display memory in the
MAX6960 and is write only. During the 8-bit address

Automatically sets the global driver devices and the global driver rows registers of the master
MAX6960 to the correct values when cascading boards.
Resets all the registers to the software reset settings.
For example:

• 4 driver devices (N-1) → Register 0x0E = 0x03
• 2 driver rows (N-1) → Register 0x0F = 0x01
Resets all the registers to the IC power-on reset (POR) settings shown in the MAX6960 data

3) Connect the MAX6960 EV kit’s 40-pin female connector (J1) to the CMODUSB board’s 40-pin male
connector (P4).
4) Install the MAX6960 evaluation software on your computer by running the INSTALL.EXE program on the
installation CD-ROM. It is highly recommended to use
the default installation path. If you desire to modify
the default path, do not use a depth of more than two
subdirectories. The program files are copied and
icons are created for them in the Windows Start
menu | Programs | Maxim MAX6960 Evaluation Kit.
5) Connect the 5V power supply between the MAX6960
EV kit’s +5V and GND pads.Turn on the 5V power supply. Do not connect the USB cable before this step.

mode, data is written to the display memory using indirection through the global display indirect address register. This display indirect address is autoincremented
after each 8-bit write to allow continuous image data
dumps into the plane of display memory in the MAX6960.
The 16-bit address mode is capable of reading or writing command/data bytes to the MAX6960’s registers. A
16-bit write can be global (updates all MAX6960s with
the same data) or local (only one MAX6960). A 16-bit
read always uses indirection through the global driver
indirect address register to select only one MAX6960.
Refer to the Register Addressing Modes section of the
MAX6960 data sheet for additional information.

The 24-bit addr modes (1 bit/pixel) tab shown in
Figure 2, and the 24-bit addr modes (2 bit/pixel) tab
shown in Figure 3, allow the user to execute 24-bit
address mode operations. A 24-bit operation is always
a direct read or write of address/data to the MAX6960’s
display memory because the memory address is
included in the 24-bit operation. Refer to the Register
Addressing Modes section of the MAX6960 data sheet
for additional information.

Maxim reserves the right to change the implementation
of this module at any time with no advance notice.
CMODUSB Power Supply
The CMODUSB board uses a MAX1658 linear regulator.

Cascading MAX6960
EV Kit Boards
The MAX6960 EV kit board was carefully designed to
cascade up to five MAX6960 EV kits. Tables 3 through
19 explain the functionality of each jumper when using
only one MAX6960 EV kit and Table 20 shows a summary of all the default settings. The 5V supply
requires a current capability of 2.5A per MAX6960
EV kit. For example, five cascaded MAX6960 EV kits
require a 5V supply capable of supplying 12.5A. If the
digit 0 and digit 1 segment current settings are
changed from 40mA to 20mA on all MAX6960 devices,
then the current requirement is cut in half. For example,
one MAX6960 EV kit would require 1.25A and five
MAX6960 EV kits would require 6.25A.

Cascading Three MAX6960 EV Kit Boards
Table 22 shows the jumper settings when cascading
three MAX6960 EV kits. The 5V supply requires a current capability of 7.5A when cascading three MAX6960
EV kits. If the digit 0 and digit 1 segment current settings are changed from 40mA to 20mA on all MAX6960
devices for all three MAX6960 EV kits, then the current
requirement is 3.75A.

Table 24 shows the jumper settings when cascading
five MAX6960 EV kits. The 5V supply requires a current
capability of 12.5A when cascading five MAX6960 EV
kits. If the digit 0 and digit 1 segment current settings
are changed from 40mA to 20mA on all MAX6960
devices for all five MAX6960 EV kits, then the current
requirement is 6.25A.

Figure 4. EV Kit Software Warning Message
Solution 1:
• Is the red power LED lit on the CMODUSB? If not,
unplug and plug in the USB cable.
• Is the USB cable connected? If not, plug in the USB
cable.
• Has the USB driver been installed? If not, refer to
step 6 in the Quick Start section or the
Troubleshooting USB.PDF included with the software.
Problem 2: Not all the LEDs light up.
Solution 2:
• Are the jumpers in the correct settings? If not, see
the Cascading MAX6960 EV Kit Boards section for
correct jumper settings.
• Are the global driver devices and global driver rows
registers configured correctly? If not, select the number of MAX6960 EV kits being used in the Cascaded
Boards: drop-down menu.
Note: Bolded text indicates changes from the default settings.
