MAX1280 Evaluation Kit/Evaluation System
1) Visit the Maxim website (www.maxim-ic.com) to
download the latest version of the USBTO232 User
Guide. Follow the steps in the USBTO232 User
Guide Quick Start section and return to step 2 of
this Quick Start section when finished.
2) Carefully connect the boards by aligning the 40-pin
header of the MAX1280 EV kit with the 40-pin con-
nector of the 68HC16MODULE-DIP module. Gently
press them together. The two boards should be
flush against one another.
3) Ensure that jumper JU1 is closed and jumper JU2
is in the 1-2 position.
4) Connect a 7VDC to 20VDC power source to the µC
module at the terminal block located next to the
on/off switch, along the top-edge of the µC module.
Observe the polarity marked on the board.
5) Connect the USBTO232 board to the 68HC16MODULE-
DIP module if you have not done so already.
6) The MAX1280 EV kit software should have already
been downloaded and installed in the USBTO232
Quick Start.
7) Start the MAX1280 program by opening its icon in
the Start | Programs menu.
8) Turn on the power supply and slide SW1 to the ON
position on the 68HC16MODULE-DIP module.
Press the OK button to automatically connect and
download the KIT1280.C16 file to the module.
9) Apply an input signal between analog common
(COM) and input channel CH0. Observe the read-
out on the screen.
Recommended Equipment (RS-232-to-COM
Port/PC Connection Option)
Before beginning, the following equipment is needed:
• MAX1280 EV system:
MAX1280 EV kit
68HC16MODULE-DIP
• A small DC power supply, such as a 12VDC, 0.25A
plug-in transformer, or a 9V battery
• A user-supplied Windows 98/2000/XP computer with
an available serial (COM) port, preferably a 9-pin plug
• A serial cable to connect the computer’s serial port to
the 68HC16MODULE-DIP
Connections and Setup
The MAX1280 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power until all connec-
tions are completed.
1) Visit the Maxim website (www.maxim-ic.com/evkit-
software) to download the latest version of the EV
kit software. Save the EV kit software to a temporary
folder and uncompress the file (if it is a .zip file).
2) Install the MAX1280 EV kit software on your com-
puter by running the INSTALL.EXE program. The
program files are copied and icons are created for
them in the Windows Start | Programs menu.
3) Carefully connect the boards by aligning the 40-pin
header of the MAX1280 EV kit with the 40-pin con-
nector of the 68HC16MODULE-DIP module. Gently
press them together. The two boards should be
flush against one another.
4) Ensure that jumper JU1 is closed and jumper JU2
is in the 1-2 position.
5) Connect a 7VDC to 20VDC power source to the µC
module at the terminal block located next to the
on/off switch, along the top-edge of the µC module.
Observe the polarity marked on the board.
6) Connect a cable from the computer’s serial port to
the µC module. If using a 9-pin serial port, use a
straight-through, 9-pin female-to-male cable. If the
only available serial port uses a 25-pin connector, a
standard 25-pin to 9-pin adapter will be required.
The EV kit software checks the modem status lines
(CTS, DSR, and DCD) to confirm that the correct
port has been selected.
7) Start the MAX1280 program by opening its icon in
the Windows Start | Programs menu.
8) Turn the power on and slide SW1 to the ON posi-
tion. The program will automatically download
KIT1280.C16 to the module.
9) Apply an input signal between analog common
(COM) and input channel CH0. Observe the read-
out on the screen.
Detailed Description
MAX1280 Stand-Alone EV Kit
The MAX1280 EV kit provides a proven printed-circuit
board (PCB) layout to evaluate the MAX1280. It must
be interfaced to appropriate timing signals for proper
operation. Connect +5V to VDD1 and VDD2, and con-
nect the ground return to GND. See the MAX1280 EV
kit schematic (Figure 1). Refer to the MAX1280 IC data
sheet for timing requirements.
