DataBridge SDR2-USB

  Serial Data Recorder

low-power low-cost small footprint no development time

Acumen Instruments Corporation's DataBridge™ SDR2-USB is an easy way to add convenient USB data storage to any device or system.

The SDR2-USB captures data from any device equipped with a serial port and stores it in a PC compatible file on a USB memory key, hard disk, or flash card reader.

No programming required.

The SDR2-USB is a hardware solution that is ready to deploy. Unlike competing solutions, no programming is required, and you don't need to install special application software. Configuration is accomplished via a file on the storage media.

Because the SDR2-USB records data to PC-compatible files, your files appear on a standard FAT32 drive letter and can be read with any computer with a USB port.

If you already use a computer or laptop for data collection, the SDR2-USB is a convenient drop-in replacement.

Even lower power consumption.

The SDR2-USB offers significant power savings over PC's, laptops, and embedded PC's, so batteries last 100 to 1000 times longer and no heat is generated.

The flexibility you need.

At Acumen, we know every application has unique requirements. You control when files are opened/closed, new file creation, and file naming. You can also incorporate date/time stamping with custom formats and millisecond precision.

The SDR2-USB supports arbitrary data port baud rates up to 921.6 kbps and alternative data word formats (e.g. 7E1).

Industry-standard storage technology.

The SDR2-USB gives you access to industry-standard USB storage media. You benefit from competitive pricing, assured compatibility with your PC, and almost unlimited data capacity.

Options for OEMs.

A circuit board-only version of the SDR2-USB, the SDR2-OEM-USB, is available for integration with your product. Customizations and quantity discounts are also available.
