Jan 2005: The CXLDK is an easy-to-use accelerometer development system that provides a simple way to interface to any Crossbow accelerometer with a PC, laptop, or other RS-232 enabled hardware. (Dec 2008: limited availability)
The CXLDK is an easy-to-use accelerometer development system that provides a simple way to interface to any Crossbow accelerometer with a PC, laptop, or other RS-232 enabled hardware. The CXLDK combines an on-board 12-bit A/D, voltage regulator and RS-232 communications port. The CXLDK data acquisition includes ACCEL-VIEW graphical valuation software for immediate evaluation of data in vibration, acceleration, and tilt sensing applications. The CXLDK is shipped complete with the cables, connectors, and power supply necessary to start development immediately.
The host PC or workstation computer communicates with the CXLDK via RS-232 at 38.4 K baud. The host PC issues a request for a sample by sending an ASCII 'G' (Get Data) to the CXLDK. The CXLDK responds with a packet of voltage data in the format described in Table 1 of the PDF data sheet. The maximum sampling rate of the board is 200 Hz.
ACCEL-VIEW evaluation software uses National Instrument's LabVIEW programming language. Writing custom software for the CXLDK is simply a matter of calling the serial I/O routines provided in standard 'C' function libraries. These routines are platform (DOS, Win, UNIX) specific.
The CXLDK ships with a small DC power supply and DB-9 (malefemale) RS-232 cable. Because the maximum sampling rate of the CXLDK is 200 Hz, the CXLDK is not appropriate for high bandwidth sensors such as our HF series accelerometers. But, you can use these sensors if an anti-aliasing filter is added to the output of the HF sensor to limit the bandwidth to below 100 Hz.
