MAX3160E Evaluation Kit
Quick Start
Recommended Equipment
receiver operate in full-duplex or half-duplex mode and
communicate at data rates up to 10Mbps. The
MAX3160E receiver represents a 1/8 unit load on the

RS-485/RS-422 bus. Resistors R5 and R6 provide a
configurable termination for the RS-485/RS-422 bus.
PCB pads and DB9 connector J1 are available for inter-
facing with an RS-232/RS-485/RS-422 serial line. See
Procedure
The MAX3160E 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) Verify that shunts are installed across pins 1-2 of
jumpers JU5, JU6, JU7, and JU8 (data communica-
tions equipment (DCE) mode).
2) Verify that a shunt is installed on jumpers JU3
(RS-232 mode) and JU4 (full-duplex mode).
3) Verify that shunts are not installed on jumpers JU1
(MAX3160E enabled), JU2 (fast mode), and JU9
and JU10 (RS-485/RS-422 differential I/O not termi-
nated).
4) Set the DC power supply output to 3.3V and disable
the output.
Table 5 and Figures 1, 2, and 3 for the respective sig-
nal pins or pads.
Jumper Selection
The MAX3160E EV kit utilizes several jumpers to reconfig-
ure circuit features and functionality: IC enable, slew-rate
selection, communication-protocol selection, full-duplex/
half-duplex communication, DTE/DCE connections, and
RS-485/RS-422 differential I/O termination.
Enable
The MAX3160E EV kit features jumper JU1 to enable the
MAX3160E or place the IC in shutdown mode, thus
reducing quiescent current. A SHDN PCB pad is also pro-
vided for the shutdown signal to interface with an external
controller. See Table 1 for configuring jumper JU1.
Table 1. MAX3160E Enable (Jumper JU1)
5) Set the logic function generator to a 3.3V P-P , 500kHz,
1.65V DC offset square wave and disable the output.
Terminate the function generator as needed.
6) Connect the DC power-supply positive output to the
VCC pad on the EV kit.
7) Connect the supply ground to the GND pad next to

8) Connect the logic function generator output to the
DI/T1IN PCB pad and connect ground to the GND
PCB pad.
9) Enable the power-supply output and then the func-
tion generator output.
10) Use the oscilloscope to measure the transmitter out-
put Z(B)/T1OUT at pin 3 of jumper JU5. Verify that
the waveform is a 500kHz square wave and is
approximately ±5V P-P .
Slew-Rate Selection
Jumper JU2 on the EV kit configures the MAX3160E
communication slew-rate mode. Slew-rate limited-mode
operation minimizes EMI radiation, while fast-mode
operation optimizes maximum data rates for either pro-
tocol. See Table 2 for configuring jumper JU2 and refer
to the MAX3160E IC data sheet for more information on
slew-rate configuration.

Detailed Description
The MAX3160E EV kit demonstrates the MAX3160E
RS-232/RS-485/RS-422 multiprotocol transceiver IC.
The EV kit operates from a 3V to 5.5VDC source capa-
ble of supplying 100mA.
The EV kit features jumpers to configure the communi-
cation protocol to RS-232 operation or RS-485/RS-422
operation. In RS-232 mode operation, the MAX3160E
communicates at data rates up to 1Mbps. In RS-485/
RS-422 mode operation, the differential driver and
