Chapter 1

Introducing the USB-CTR04

The USB-CTR04 is a USB 2.0 high-speed data acquisition device that provides the following features:

 Four counter I/O

o High-speed pulse counter for general counting applications; multiple counting modes supported o 48 MHz, programmable resolution up to 64-bits o An aggregate scan rate of 8 MB/s

 Four PWM timers with count, period, delay, and pulse-width registers  Eight individually-configurable digital I/O channels  External clock input and internal clock output  External digital trigger; software-selectable for edge or level sensitive, rising or falling edge, high or low

level

The USB-CTR04 is a USB 2.0 high speed device that is compatible with USB 3.0 ports. The device is also compatible with USB 1.1 ports, but use with this older hardware is not recommended due to longer initialization times that can occur when the USB-CTR04 is connected through USB 1.1 ports or hubs.

I/O connections are made to two banks of screw terminals. The USB-CTR04 is powered by the 5 volt USB supply from your computer.

Functional block diagram

Device functions are illustrated in the block diagram shown here.

Chapter 2

Installing the USB-CTR04

Unpacking

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the device 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.

Installing the software

Refer to the MCC DAQ Quick Start for instructions on installing the software on the MCC DAQ CD. Refer to

the device product page on the Measurement Computing website for information about the included and optional software supported by the USB-CTR04.

Install the software before you install your device

The driver needed to run the USB-CTR04 is installed with the software. Therefore, you need to install the software package you plan to use before you install the hardware.

Installing the hardware

To connect the USB-CTR04 to your system, connect the USB cable to an available USB port on the computer or to an external USB hub connected to the computer. Connect the other end of the cable to the USB connector on the device. No external power is required.

When connected for the first time, a device. When the dialog closes, the installation is complete. The successfully installed (see Figure 2 on page 7).

If the Status LED turns off

If communication is lost between the device and the computer, the Status LED turns off. To restore communication, disconnect the USB cable from the computer and then reconnect it. This should restore communication, and the Status LED should turn on.

LED indicators

The device has two LED indicators – Status and Activity.

 The  The

Refer to Figure 2 on page 7 for the location of these LEDs.

Status LED (top) turns on when the device is detected and installed on the computer. Activity LED (bottom) blinks when data is transferred, and is off otherwise.

USB connector

The USB connector provides 5 V power and communication.

Counter I/O and gating

The USB-CTR04 has a counter input (CxIN), counter output (CxO), counter gate (CxGT) screw terminal for each of its four counter channels.

Counter inputs can be read asynchronously under program control, or synchronously as part of a digital scan group. In both cases, you can configure counters so that they:

 get set to 0 after each read  count up or down and then roll over at a user-set limit  count until the user-set limit has been reached.

Counter inputs can concurrently monitor time periods, frequencies, pulses, and other event-driven incremental occurrences directly from pulse-generators, limit switches, proximity switches, and magnetic pick-ups.

Counter outputs can be used to control or transmit signals to external devices, and also to USB-CTR04 counter inputs, counter gates, or digital inputs. Counter outputs are commonly used in

mode.

Counter gates use input signals to clear a counter, change counter direction, or start/stop counting. Gate options are software-selectable and are available when counting in Totalize mode.
