The USB-7202 and USB-7204 boards, now available from Firetail , are multifunction measurement and control devices intended specifically for the Message-Based DAQ (MBD) protocol. They are the MDB equivalents of Measurement Computing’s famous USB-1608FS and USB-1208FS modules, respectively.
Both the USB-7202 and the USB-7204 are shipped as open stackable boards without enclosures. The new 7000 series product line, which includes the USB-7202 and USB-7204 boards, combines small form-factor, bus-powered USB hardware, and a light and agile software framework that can be ported to multiple operating systems. The software framework, a core technology to the series, is called Message-Based DAQ (MBD). MBD is a well-defined protocol that permits the programming of DAQ devices using simple text-based messages.
The MBD protocol greatly simplifies driver and application development because all DAQ operations are programmed through a common command interface, which is composed of a consistent, extensible firmware interface and an open-source, cross-platform API. The firmware parses text-based messages through a device driver and converts these messages into DAQ-specific commands that control the device. This concise and well-documented interface allows driver development for multiple operating systems, and also supports O/S-independent embedded systems that need to communicate only over a USB root port
The USB-7202 features:
• 8 analog input channels
• 16-bit resolution
• 100 kS/s max total throughput (200 kS/s in burst mode)
• Simultaneous sampling (1 A/D converter per input)
• One 32-bit event counter • External digital trigger input
• 8 digital I/O lines
• External pacer
• Detachable screw terminals The USB-7204 features:
• 8 single-ended or 4 differential analog inputs
• Two 12-bit analog outputs
• 12-bit (DI), 11-bit (SE) resolution adjusted in FW to display as 12-bit (SE is 12-bit, even values only)
• Up to 50 kS/s sample rate
• 16 digital I/O lines
• Detachable screw terminals Power for the USB-7202 and the USB-7204 devices comes from the +5 volt USB supply from your computer. No external power is required.
The USB-7202 and USB-7204 ship with a USB cable (2-meter length), Standoff and screws and a CD containing a Windows installer file (msi), an Archive file containing installation files for Linux OS and the MC7000 help file.
