Quick Start
Required Equipment
Before beginning, the following equipment is needed:
? One +5V 550mA current-limited power supply with
a built-in current meter
? One voltmeter
Note: Indicate that you are using the MAX13487E or
MAX13488E when contacting these component suppliers.
Note: The +5V supply powering the MAX13487E EV kit
must be current-limited at 550mA and the output load
current for the output should be limited to less than
300mA.
Detailed Description of Hardware
The EV kit features a MAX13487E IC in an 8-pin SO sur-
face-mount package and demonstrates the ESD-
?
?
One logic signal generator
One oscilloscope with a differential probe
protected MAX13487E RS-485/RS-422 AutoDirection
transceiver. The differential driver and receiver are con-
figured for half-duplex operation and communicate up
Procedure
The MAX13487E EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Connect a voltmeter to the VOUT and GND PC pads.
2) Verify that a shunt is not installed across the pins of
jumper JU1 (U2 enabled).
3) Verify that a shunt is installed across pins 1-2 of
jumper JU2 (U1 enabled).
4) Verify that a shunt is installed across the pins of
jumpers JU3 (AutoDirection enabled), JU4 (pull-
down), JU6 (pullup), and JU5 (bus terminated).
5) Connect the +5V power supply to the VIN pad.
Connect the power supply’s ground to the PGND pad.
6) Turn on the power supply and verify that the volt-
meter at VOUT reads +5V.
7) Using the logic signal generator, apply a +5V logic
signal to the TXD PCB pad and PGND.
8) Using the oscilloscope and differential probes, verify
the signal at the A-B pads (isolated side).
to 500kbps. The transceiver circuit is a 1/4-unit load on
the receiver’s bus.
The EV kit features PCB pads to ease interfacing with
the driver/receiver logic signals on the non-isolated side
using the TXD, RXD, and PGND pads, respectively. The
MAX13487E IC is powered from the isolated VOUT
supply. Photocoupler U4 provides isolation for the
receiver’s RO signal (RXD pad) and U5 provides isola-
tion for the data-in DI signal (TXD pad).
The EV kit demonstrates the MAX13487E slew-rate
limited driver, which minimizes EMI radiation.
Photocouplers U4 and U5 are rated for up to 15Mbps.
The MAX13487E receiver signal is provided at the RO
pin. The RO pin will give a logic-high if A-B > +200mV.
A logic-low is given if A-B < -200mV. Refer to the
Transmitting and Receiving sections in the Function
Tables in the MAX13487E/MAX13488E IC data sheet
for additional information on the AutoDirection circuitry
operation. Also see the AutoDirection and Receiver
Enable Selection section in this document for configur-
ing the AutoDirection and receiver operation.
