The MAX9257A/MAX9258A EV kit software contains
four tab sheets: ECU Control, Deserializer
MAX9258A, Serializer MAX9257A, and Camera
Control.
Warning: When the MAX9257A/MAX9258A UART baud
rate ranges are changed, they do not take effect until
the next control channel is entered. The ECU baud rate
should not be changed during the current control chan-
nel.
The ECU Control tab sheet (Figure 3) lets the ECU con-
figure the MAX9258A, MAX9257A, and the camera.
The ECU UART baud rate can be selected by choosing
the appropriate baud rate in the Select ECU UART
Baud Rate drop-down list. By default, the UART speed
is 400kbps. In base mode, the UART baud rate should
not be higher than 4.25Mbps.
Except for the menu-driven commands that can be
generated on the Deserializer MAX9258A, Serializer
MAX9257A, and Camera Control tab sheets, the ECU
commands can be written by typing commands in the

box. Similarly, the ECU commands can be read by typ-
ing commands in the ECU Reads N Bytes from
MAX9257A/58A/Camera edit box. The write or read
commands are not executed until the corresponding
Write or Read button is pressed. Follow the instructions
displayed on the software GUI.
When the EV kit is powered up the first time, and the
MAX9257A is configured to be powered up remotely by
the ECU (REM is high), press the ECU Wakes Up
MAX9257A button to wake up the MAX9257A. Refer to
the Remote Power-Up of the MAX9257A (REM = Pulled
Up to V
data sheet for timing requirements of the remote wake-
up.
Check the Prefix a SYNC frame everytime a
read/write command is sent checkbox when a SYNC
frame is desired before sending a command to the
MAX9258A, MAX9257A, or the camera. A SYNC frame
is needed only once every control channel.
Check the Postfix an END frame everytime a read/write
command is sent checkbox when an END frame is
desired after sending a command to the MAX9258A,
MAX9257A, or the camera. Do not send END frame after
a READ command. In a real application, the ECU can
send END frame after the READ operation is completed.
Press the Reset the EVKIT button to reset the EV kit
software and hardware. The user must manually dis-
connect and reconnect the power supply to reset the
EV kit hardware.
On the Deserializer MAX9258A tab sheet (Figure 4), the
ECU can write or read all registers on the MAX9258A by
pressing the Write or Read buttons on the right of each
register. Refer to the MAX9257A/MAX9258A IC data
sheet for the definition of each register.
Four registers on each of the MAX9258A and
MAX9257A should have the same values. They should
be configured simultaneously for the SerDes pair to
work properly. Check the Write Both 9258A&9257A
checkbox to enable the write operation of the two
devices on the same control channel.
On the bottom-left side of the software window, press
the Reset MAX9258A GUI button to set all of the GUI
values to the MAX9258A power-on-reset values. No
operations are executed on the actual MAX9258A
device. The other four buttons: Read MAX9258A &
9257A, Write MAX9258A & 9257A, Read MAX9258A,
and Write MAX9258A let the user read or write to the
MAX9258A and the MAX9257A simultaneously or indi-
vidually.
