Evaluates: MAX14890E 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 singleended 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(R) form-factor for easy software evaluation and development. Features Four Configurable Differential or Single-Ended Receivers SPI or Pin-Controlled Operation USB-PC Connection Proven PCB Layout Fully Assembled and Tested 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. Ordering Information appears at end of data sheet. 7) Verify that ZO is switching as expected. 8) Repeat with the A, A, B, B, DIY, and Y inputs.

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(R) or Arduino board (Figure 2). 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. Table 1.

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 Configuring 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. 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/270 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 200 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. Table 2.
