MAX14890E Evalution Kit
General Description
The MAX14890E evaluation kit (EV kit) is a fully assembled
and tested PCB that contains the MAX14890E incremental
encoder interface. The MAX14890E incremental encoder
receiver contains four differential receivers and two single-
ended receivers for RS-422, HTL, TTL, and digital signals.
Power for the transceiver can be provided from a single
+5V source or from an on-board 24V to 5V step-down
circuit. The MAX14890E EV kit includes terminal blocks
for motor and power connections.
On-board switches and jumpers are included to configure
the MAX14890E in pin-control mode. The evaluation
board is also designed with the Arduino® form-factor for
easy software evaluation and development.

Quick Start
Recommended Equipment
●MAX14890E EV kit
● 5V, 500mA power supply
● Function generator or logic signal generator
● Oscilloscope
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation before exercising the full
features of the device:
1) Verify that all the jumpers are in their default positions,
as shown in Table 1.
2) Set the DC power supply to +5V and connect between
the VCC and GND test points on the EV kit.
3) Connect the function generator to the Z input on the T3
block terminator. Connect the Z input to ground. Set the
function generator to generate a ±2V 100kHz signal.
4) Connect the oscilloscope to the ZO output.
5) Turn on the power supply.
6) Turn on the function generator.
7) Verify that ZO is switching as expected.
8) Repeat with the A, A, B, B, DIY, and Y inputs.

MAX14890E Evalution Kit
Detailed Description
The MAX14890E EV kit is a fully tested circuit board
demonstrating the capabilities of the MAX14890E
incremental encoder interface.
The EV kit includes an on-board 24V-to-5V step-down
supply, fault indicator LEDs, jumpers for pin-mode control,
and SPI-connections. The board is designed to operate
either as a stand-alone board or with an external mbed®
or Arduino board (Figure 2).
Powering the Board
The MAX14890E operates from a single +5V supply. A
separate logic-supply (VL) is also available. Apply +5V
to VCC (TP1) to power the board using a single supply.
Shunt the J1 jumper to connect VL to VCC, or apply a
separate voltage as low as 1.62V to VL (TP2) for a separate
logic-supply.
The EV kit also includes a 24V step-down circuit. To
power the board from an external +24V source, ensure
that the J1 jumper is open and connect the +24V supply
and GND lead to the T6 terminal block. Put a shunt across
the J2 jumper to power VCC with the +5V generated from
the step-down circuit.

Mode Selection
The MAX14890E operates in either pin-control or SPI
mode. The MAX14890E EV kit is designed to operate as
a stand-alone board in pin-control mode, but can also be
evaluated in SPI mode. Pin-control mode is the default
state of the board.
Ensure that all switches are in the off state (to the left) for
pin-control mode.
To evaluate the board in SPI mode, set all of the
switches on the S1 switch to the on state (to the right).
The MAX14890E EV kit has been designed to connect
directly to an Arduino or mbed LPC1549Xpress board
for easy software evaluation. See Maxim Integrated’s
website for sample code and application notes.
Pin-Control Mode
Conguring the RxA, RxB, RxZ, and RxY
Receivers
On-board jumpers are available for pin-control mode
configuration. J12 sets the SNGL/CLK input. J13 sets the
TTL/SDI input. J8 sets the DI/TTLY input. See Table 2 for
receiver configuration settings.
Conguring the RxD2 and RxD3 Receivers
On-board jumpers are used to set the DI/TTL2 (J9) and
DI/TTL3 (J10) inputs in pin-control mode. These inputs
configure the D2 and D3 receivers, respecitively (Table 3).
Cable Termination
Transmission line termination is required for RS-422,
HTL, and TTL high-speed signals on long cables. The
EV kit includes selectable termination for each of the the
RxA, RxB, RxZ, and RxY receivers. For HTL signals,
100pF/270Ω AC-termination with a series RC is available.
For RS-422 and TTL signal levels, close the associated
jumper (Table 4) to enable the on-board 200Ω termination
for each receiver.
Fault Indicators
The MAX14890E detects common RS-422/HTL/TTL/DI
faults. These faults include low differential input signals,
open-wire, short-circuits, and inputs voltages that are
outside the normal operating voltage range (below -18V
and +18V). The EV kit includes on-board LEDs for visual
indicators when a fault condition occurs on any of the
RxA, RxB, RxZ, RxY, RxD2, and RxD3 receivers. LEDs
turn on when a fault condition occurs.
