Acumen DataBridge SDR2-CF Serial Data Recorder

No programming required.

The SDR2-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 SDR2-CF records data to PC compatible files, your files appear on a standard drive letter and can be read with any CompactFlash card reader. The SDR2-CF adds support for the FAT32 file system for even greater compatibility.

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

Even lower power consumption.

The SDR2-CF 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 SDR2-CF now also operates from a wider input voltage range, further simplifying system integration.

For applications that demand it, the SDR2-CF also offers a low-power mode that further cuts power consumption and the ability to disable LED indicators for even more battery life.

The flexibility you need.

At Acumen, we know every application has unique requirements. For devices that require it, the SDR2-CF can send commands or messages to the attached device on initialization, shutdown, or at specific intervals. You also control when files are opened/closed, file naming, and date/time stamping.

With the SDR2-CF, we’ve gone a step further. The SDR2-CF now supports arbitrary data port baud rates up to 921,600 baud, the ability to send break characters to a device, and output messages with embedded binary codes.

Using the SDR2-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 SDR2-CF gives you access to industry-standard CompactFlash solid-state 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-CF, the SDR2-OEM-CF, is available for integration with your product. Customizations and quantity discounts are also available.
