DataBridge SDR-CF

  Serial Data Recorder

DataBridge SDR-CF

  • low-power
  • low-cost
  • small footprint
  • no development time

Acumen Instruments Corporation™'s DataBridge SDR-CF is another way Acumen Instruments makes it easy to add data storage to any device or system.

The SDR-CF captures data from any device equipped with a serial port and stores it in a PC-compatible file.

No programming required.

The SDR-CF 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. All configuration is done using terminal software via your computer's serial port.

Because the SDR-CF records data to PC-compatible files, your files appear on a standard drive letter and can be read with any common CompactFlash card reader.

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

Low power consumption.

The SDR-CF consumes less than 1 Watt, offering significant power savings over PC's, laptops, and embedded PC's, so batteries last 10 to 100 times longer and no heat is generated. The SDR-CF operates from a 7-30 VDC power supply, simplifying system integration.

The flexibility you need.

At Acumen, we know every application has unique requirements. For devices that require it, the SDR-CF can send commands to the attached device on initialization, shutdown, or at specific intervals. You also control when files are opened and closed, how files are named, and date/time stamping.

Using the SDR-CF's configuration port, you can connect to a computer to control and monitor your recording, download files, change recording settings, or communicate with your device using serial passthrough mode.

Industry-standard storage technology.

The SDR-CF gives you access to industry-standard CompactFlash solid-state storage media. You benefit from competitive pricing as well as assured compatibility with your PC.

Options for OEMs.

A board-only version of the SDR-CF, the SDR-OEM-CF, is available for integration with your product. Other OEM features include a remote panel interface connection. Customizations and quantity discounts are also available.

See it for yourself.

The DataBridge SDR-CF starter kit includes everything needed to incorporate the SDR-CF in your application today.
