Introducing the USB-7204

The USB-7204 is a USB 2.0 full-speed device that provides the following features:

 Eight channels of 16-bit analog input configurable for eight 11-bit single-ended inputs (represented as

12-bit data — even values only) or four 12-bit differential inputs.

 Two 12-bit analog outputs

 16 individually configurable digital I/O channels

 32-bit event counter

 Digital trigger input

 Bidirectional SYNC pin for external clocking and synchronization with another board

The USB-7204 device is compatible with both USB 1.1 and USB 2.0 ports. The speed of the device may be

limited when using a USB 1.1 port due to the difference in transfer rates on the USB 1.1 versions of the

protocol (low-speed and full-speed).

The USB-7204 is powered by the +5 volt USB supply from your computer; no external power is required. A

USB cable is shipped with the device.

Caution! There are no product safety, electromagnetic compatibility (EMC), or CE marking compliance

claims made for the USB-7204. The USB-7204 is intended for use as a component of a larger

system. MCC can help developers meet their compliance requirements. The end product supplier,

however, is responsible for conforming to any and all compliance requirements.
