MAX186 EV System Quick Start

The MAX186 EV system includes a Maxim 80C32 module

and a MAX186 EV kit. The two connect through a 40-pin

data connector on adjoining edges of the boards. The EV

system then connects to an IBM-compatible computer

running software provided with the MAX186 EV kit.

The personal computer and the 80C32 module are con-

nected via a standard RS-232 serial communication

port. If the serial port on the personal computer has the

standard 9-pin connector, a straight through cable is

used to attach the board. Systems with a 25-pin serial

port connector need an adapter or adapter cable (D25

female to D9 male). Both the adapter and the cable are

available at most computer supply stores.

The steps for using the MAX186 EV system are outlined

as follows:

1) Visit www.maxim-ic.com/evkitsoftware 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 MAX186 EV kit software on your comput-

er by running the INSTALL.EXE program. The pro-

gram files are copied and icons are created for

3) Connect the MAX186 evaluation board to the 40-pin

data connector on the Maxim 80C32 module.

4) Connect an 8V to 16V source to the 2-pin power

connector on the 80C32 module. The positive lead

connects to the terminal marked VIN.

5) Connect a cable from the personal computer serial

connector to the 9-pin RS-232 connector on the

80C32 module.

6) Turn on the power to the 80C32 module. The switch

is located on one edge of the board. The LED indi-

cates power from the on-board regulator.

7) Start the MAX186 program by opening its icon in

the Windows Start | Programs menu.

8) The 80C32 will transmit a logon message and RAM

test results when communications are initialized.

The MAX186 RAM resident program will then be

automatically downloaded.

9) Connect the analog inputs to the CH0-CH7 pads

and observe the readout on the screen.

MAX186 EV Kit Quick Start

This section applies only to use of the MAX186EVKIT-

DIP without the 80C32 module.

The MAX186 evaluation board can easily be configured

in the quick-look circuit of Figure 5 of the MAX186/

MAX188 data sheet. All of the necessary digital pins

are provided on the 8-pin header located along the bot-

tom edge of the board. Each pin function is indicated

by labels below the header.
