MAXREFDES24EVSYS User Manual

1 Introduction

The MAXREFDES24EVSYS design accelerator kit allows users to quickly demonstrate and evaluate the functionality of Maxim Integrated’s 4-channel analog output (AO) r eference design (MAXREFDES24 the need for a bench power suppl y, digital multimeter , or Xilinx de velopment kit. The reference board connects to a PC through an included USB-to-SPI adapter ( A universal power adapter is included for providing 24V DC power.

To exercise the AO reference design, a USB-powered signal capture board (MAXADCLITE2) utilizing one of Maxim Integrated’s 12-bit analog-to-digital c onverters (ADCs) is also included. The sim ple tool provides two inputs capable of m easuring unipolar analog control signals up to 10V (or 20mA with selectable term ination resistor).

Windows®-based grap hical user interf aces (GUIs) c ommunicate with the boards for generat ing and ca pturing various signal test patterns. An intuitive alarm interface is also provided for demonstrating the digital diagnostics capabilities of the MAX15500 output conditioners.

2 Software Description

There are two Windows G UI applications inc luded with MAXREFDES24EVSYS that can be executed direc tly from the USB flash drive after USB connections have been established with the boards and Windows completes driver installation. See the Graphical User Interfaces

• 4-Channel Analog Output GUI utilizes the U SB2PMB1 adapter for exercising the di gital interface of the MAXREFDES24 desig n. This includes the SP I port of the MAX5134 4-chan nel DAC and multiple MAX15500 output conditioners. This GUI application utilizes the .NET 4.0 platform and does not require installation of any Maxim Integrated software.

• MAXADCLite2 GUI for capturing analog test signals with the MAXADCLITE2 board in order to evaluate the performance of the AO reference design. This application does not require installation.

If only two (2) USB por ts are available, cop y the USB flash dri ve contents directly to your local har d drive or download the USB flash drive contents from www.maximintegrated.com/MAXREFDES24

3 Hardware Connections

This section describes the basic connections with the MAXREFDES24EVSYS kit.

• The user must pr ovide a Windows PC with two available USB ports and an AC outlet for operating the MAXREFDES24EVSYS kit. In addition to providing PC communications, the USB ports power the USB2PMB1 and MAXADCLITE2 boards.

• A universal AC wall adapter and test clip adapter are includ ed for providing 24V DC to the MAXREFDES24 analog output board. A ny DC supply with 20–30V DC and >150mA output capabilit ies can be substitute d for the AC wall adapter.

• The MAXREF DES24 and USB2PMB1 boards m ate together via a 12-pin Pmod Type 2A connector. For more information on the Pmod form factor, refer to the Digilent Pmod

www.DigilentInc.com.

• A pair of wires with test clips is provided for establishing an analog control signal between one of the MAXREFDES24 outputs and one of the MAXADCLITE2 inputs.

Interface Specification or visit

3.1 USB2PMB1 to MAXREFDES24

Connect the MAXREFDES24 board to the USB2PMB1 adapter as shown above. Both 12-pin connectors should be on the same side of the PCB when mated together.

3.2 24VDC to MAXREFDES24

Connect the color c oded test clips of the DC po wer adapter to the M AXREFDES24 board as shown a bove. Red clips connect to +24V and black clips connect to PGND.
