Quick Start

Recommended Equipment

• MAX3162 EV kit

• User-supplied WindowsM 2000, Windows XPM, or

Windows VistaM PC with a spare RS-232 serial port

Note: In the following sections, software-related items

are identified by bolding. Text in bold refers to items

directly from the EV kit software. Text in bold and under-

lined refers to items from the Windows operating system.

Procedure

The MAX3162 EV kit is fully assembled and tested. Follow

the steps below to verify board operation. Caution: Do

not turn on power supply until all connections are

completed.

1) Visit www.maxim-ic.com/evkitsoftware to download

the latest version of the EV kit software, 3162Rxx.ZIP.

Save the EV kit software to a temporary folder and

uncompress the ZIP file. The EV kit software consists

of the free, open-source terminal emulator, RealTerm

(also available from http://realterm.sourceforge.net).

2) Verify that all jumpers (JU1–JU11) are in their default

positions, as shown in Table 1.

3) Move the shunts of jumpers JU7 and JU8 to the 1-2

position to enable RS-485 loopback.

4) Connect the positive terminal of the 5.0V supply to

VCC on the EV kit and connect the negative terminal

of the 5.0V supply to GND.

5) Connect the DB9 I/O extension cable between the EV

kit and the computer’s serial port.

6) Start the RealTerm software by opening its icon in

the Start | Programs menu. The RealTerm software

main window appears, as shown in Figure 1. Note:

If the serial cable is connected to a serial port other

than COM1, bring up the Port tab and open the cor-

responding serial port.

7) In the RealTerm window, click in the display area

and type on the keyboard. The digital loopback con-

nection immediately relays each character from the

receiver to the transmitter, so each character typed

on the keyboard appears in the display area.

8) Move the shunt of jumper JU3 to the 2-3 position to

disable the RS-232 transmitter.

9) In the RealTerm window, click in the display area and

type on the keyboard. With the RS-232 transmitter

disabled, characters typed on the keyboard do not

appear in the display area.

Detailed Description of Hardware

The MAX3162 evaluation kit (EV kit) provides a proven

design to evaluate the MAX3162 programmable RS-232/

RS-485/RS-422 multiprotocol transceiver. The MAX3162

EV kit is configured to bidirectionally convert between the

RS-232 and RS-485/RS-422 signals. The DB9 connector

(J1) provides the RS-232 connection to the MAX3162

and the terminal block (J2) provides the RS-485 connec-

tions to the MAX3162.
