MAX3161E Evaluation Kit
RS-232/RS-485/RS-422 Protocol Selection
EV kit jumper JU3 sets the communication protocol to
either RS-232 or RS-485/RS-422. See Table 3 for
configuring jumper JU3. For additional protocol-config-
uration information, refer to the Functional Diagrams
section of the MAX3161E IC data sheet.
RS-485/RS-422 Communication Mode
EV kit jumper JU4 configures the MAX3161E IC’s RS-485/
RS-422 communication mode to full duplex or half
duplex. To receive RS-485 data, disable the RS-485
outputs by driving the DE485/T2IN PCB pad low. See
Table 4 to configure jumper JU4 for the desired mode
of communication.
Header J2 is labeled for full-duplex RS-485/RS-422
communication; however, the driver outputs (Y and Z)
are multiplexed with the receiver inputs (A and B) dur-
ing half-duplex communication. Refer to the Half-
Duplex RS-485/RS-422 Operation and MAX3161E
Functional Diagram sections of the MAX3161E IC data
sheet for further details.

DTE/DCE Connections
The EV kit features jumpers JU5, JU6, JU7, and JU8 to
configure the RS-232 connector J1 as a data terminal
equipment (DTE) or as a data communications equip-
ment (DCE) connector. See Table 5 for configuring the
respective jumpers for DTE or DCE connection mode.
RS-485/RS-422 Termination
EV kit jumpers JU9 and JU10 configure the RS-485/RS-
422 termination. JU9 sets the input termination with
resistor R6. JU10 sets the output termination with resistor
R5. See Table 6 for the RS-485/RS-422 termination
options.
EV Kit I/O Connections
The MAX3161E EV kit features PCB pads for interfacing
with logic signals and DB9 connector J1 to interface
with an RS-232 serial line. Terminal block J2 eases con-
nection to an RS-485/RS-422 bus. See Figures 1 or 2 for
RS-232 or RS-485/RS-422 transceiver functional modes.
The RS-232/RS-485/RS-422 input range is ±25V and
the output range is ±5V.
