_______________________________________________________________________________________

MAX1132 Stand-Alone EV Kit

The MAX1132EVKIT provides a proven PCB layout to

facilitate evaluation of the MAX1132. It must be inter-

faced to appropriate timing signals for proper opera-

to AGND (Figure 1). Refer to the MAX1132 data sheet

for timing requirements.

MAX1132 EV System

The MAX1132EVC16 EV system operates from a user-

supplied +7VDC to +20VDC power supply. Windows

98/2000/XP-compatible software running PC interfaces

to the EV system board through the computer’s serial

communications port (virtual COM port). See the Quick

Start section for setup and operating instructions.

Quick Start

Recommended Equipment—USB Port PC

Connection Option

Before you begin, the following equipment is needed:

•

MAX1132EVC16 (contains MAX1132 EV kit board,

68HC16MODULE-DIP, and USBTO232)

•

Small DC power supply, such as a 12VDC, 0.25A

plug-in transformer, or a +9V battery

•

PC-compatible computer running Windows 2000/XP

with an available USB port to connect to the

USBTO232 board

•

USB cable included with the USBTO232

Procedure

Caution: Do not turn on the power until all the con-

nections are completed.

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

connector of the MAX1132 EV kit with the 40-pin

connector of the 68HC16MODULE-DIP module.

Gently press them together. The two boards should

be flush against one another.

3) Check the jumper settings (Table 1).

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 mod-

ule. Observe the polarity marked on the board.

5) Connect the USBTO232 board to the 68HC16MOD-

ULE-DIP module if you have not done so already.

6) The MAX1132 EV kit software should have already

been downloaded and installed in the USBTO232

Quick Start.

7) Start the MAX1132 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 KIT1132.C16 file to the module.

9) Apply the input signal across the pins of JU2.

Observe the readout on the screen.

Recommended Equipment—RS-232/COM

Port PC Connection Option

Before you begin, the following equipment is needed:

•

MAX1132EVC16 (contains MAX1132EVKIT board

and 68HC16MODULE-DIP)

•

Small DC power supply, such as a 12VDC, 0.25A

plug-in transformer, or a +9V battery

•

PC-compatible computer running Windows

98/2000/XP with an available serial communications

port, preferably a 9-pin plug

•

Serial cable to connect the computer’s serial port to

the 68HC16MODULE-DIP

Procedure

Caution: Do not turn on the power until all the con-

nections 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 MAX1132 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

connector of the MAX1132 EV kit with the 40-pin

connector of the 68HC16MODULE-DIP module.

Gently press them together. The two boards should

be flush against one another.

4) Check the jumper settings (Table 1).

5) Connect a +7VDC to +20VDC power source to the

68HC16MODULE-DIP module at the terminal block

J2 located next to the ON/OFF switch. Observe the

polarity marked on the board.

6) Connect a cable from the computer’s serial port to

the 68HC16MODULE-DIP module. If using a 9-pin

serial port, use a straight-through, 9-pin female-to-
