• Manufacturer: Maxim Integrated
• Series: MAX155, MAX156r

10) Install each IC and solder in place if not in sockets.
When assembly is complete, carefully examine the
board for possible solder shorts and misinserted parts,
Verify that all ICs are in their proper position and not
reversed. Verify that all tantalum capacitors are insert-
ed with their positive pin aligned with the “+” sign on
the board. Verify that D1 is not reversed.
The MAX155 evaluation board connects to one of the
two possible serial ports (COM1 or COM2) commonly
found on an IBM-compatible personal computer. The
user must determine and supply the type of cable
needed to make the connection. The connector for
these ports can be a D9 (9-pin) or D25 (25-pin) con-
nector. The connector on the EV kit is a D9 connector.
Consult the computer user manual for the information
regarding the location and type of the serial communi-
cations connector(s) available on your system.
If the computer has a D9 connector available, a stan-
dard straight-through cable can be used. If the only
available COM port connector is a D25, an adapter is
required. The necessary adapter is commonly used
with other serial-operated devices and is readily avail-
able at computer supply stores.
The RS-232 protocol defines the function of each con-
nector pin. It requires that the equipment on one end of
a cable function as data terminal equipment (DTE) and
the other as data communications equipment (DCE).
The personal computer (PC) end is the DTE and the
MAX155 EV kit is connected as DCE.

Examine each device after soldering to ensure
there are no solder bridges shorting between pins.
Proper ESD prevention techniques should be fol-
lowed when handling any of the semiconductors.

Setup Instructions
Before doing anything else, make a copy of the disk
provided with the MAX155 EV kit, Use the copy for all
operations and keep the original in a safe place. If a
hard disk is available, all files can be copied to a direc-
tory and executed from there.
If the files are to be accessed from a floppy drive,
select the drive for default operation. For example,
enter A: to use drive A. If the files have been copied to
a hard disk, set the default directory to the one holding
the MAX155 files.
The disk contains a README file that lists any changes
to the hardware or software. Read the README file
before proceeding. The MAX155 EV Kit Users Manual,
which covers the operation of the program, is also on
the disk (MAX155EV.doc). If a printer is available, print
