Chapter 1

Introducing the USB-4302

The USB-4302 is a USB-based high-performance, low-cost counter/timer device.

The USB-4302 is designed with a 9513 counter/timer chip. The 9513 chip has five independent 16-bit counters (65,536 counts). Each counter has an input source, internal count register, load register, hold register, output, and gate.

The 9513 is software-programmable for event counting, pulse and frequency measurement, alarm comparisons, and other input functions. The 9513 can generate frequencies with either complex duty cycles, or with one-shot and continuous-output modes. For detailed information on the 9513 counter/timer, refer to the 9513 data sheet at www.mccdaq.com/PDFmanuals/9513A.pdf.

You can chain up to five 9513 counters together using software to enable a 32-, 48-, 64-, or 80-bit counter that does not require hardware connections. The gate source and gating functions are software-programmable.

An eight-bit, high-current digital output port provides logic-level control, and can be used to switch solid state relays. An eight-bit digital input port can be used to sense contact closures and other TTL level signals.

All I/O connections are made to a 37-pin connector. The USB-4302 is powered by the +5 volt USB supply. No external power is required.

Software features

For information on the features of InstaCal and the other software included with your USB-4302, refer to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.

Check www.mccdaq.com/download.htm for the latest software version.

Connecting a USB-4302 to your computer is easy

Installing a data acquisition device has never been easier.

 The USB-4302 relies upon the Microsoft Human Interface Device (HID) class drivers. The HID class

drivers ship with every copy of Windows that is designed to work with USB ports. We use the Microsoft HID because it is a standard, and its performance delivers full control and maximizes data transfer rates for your USB-4302. No third-party device driver is required.

 The USB-4302 is plug-and-play. There are no jumpers to position, dual in-line package (DIP) switches to

set, or interrupts to configure.

 You can connect the USB-4302 before or after you install the software, and without powering down your

computer first.

When you connect an HID to your system, your computer automatically detects it and configures the necessary software. You can connect and power multiple HID peripherals to your system using a USB hub.

 You can connect your system to various devices using a standard four-wire cable. The USB connector

improves upon serial and parallel port connectors with one standardized plug-and-port combination.

 Data can flow two ways between a computer and peripheral over USB connections.

Additional documentation

In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at

www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf). This booklet supplies a brief description of

the software you received with your USB-4302 and information regarding installation of that software. Please read this booklet completely before installing any software or hardware.

Unpacking the USB-4302

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the USB-4302 from its packaging, ground yourself using a wrist strap or by simply touching the computer chassis or other grounded object to eliminate any stored static charge.

If any components are missing or damaged, notify Measurement Computing Corporation immediately by phone, fax, or e-mail:

 Phone: 508-946-5100 and follow the instructions for reaching Tech Support.  Fax: 508-946-9500 to the attention of Tech Support  Email: techsupport@mccdaq.com
