Add GPS timing to legacy (pre-GPS) systems!

Eliminate clock drift for systems with free-running clocks by adding a GPS-NS timing card. If your legacy system has serial and digital input ports and a timer, you can upgrade your timing to GPS with a software-only solution. Simply connect the GPS-NS NMEA output to your serial port and the GPS-NS PPS output to the digital input port which controls a counter. The counter's counts is the time offset from the second (X.00000) and NMEA RMC is the time of that second. With these two numbers the time is determined to the resolution of the counter. For example, if the counter is clocked at 1 MHz, then the time is accurate to one microsecond.

NetDAS 32-channel 24-bit data acquisition

For data acquisition applications (DA) requiring high channel counts, NetDAS-32 is a cost-effective solution. Applications include wired seismic arrays in structures, laboratory sensory DA, seismic surveys or other DA where large numbers of analog sensors need digitization with GPS timing and 24-bit resolution. NetDAS offers TCP/IP connectivity via the NetDAS Tools client/server software (remote data collection, triggering, formatting, performance logging, data concentration). For about $9500, you won't find a better value!

Watchdog Power Supply

A Watchdog Power Supply (WDPS) is useful for systems that run continuously as a WDPS will automatically reboot the system if it stalls, stops or crashes. The WD is "kicked" every few seconds with a CPU generated pulse. If the pulse is missing (CPU has crashed) the power is recycled. A cold reboot is often the most effective way to recover from software bugs, power glitches, USB stack errors or any other problem that causes the program to halt. To use this WDPS just have it supply the 5VDC to your CPU and have the CPU provide a periodic pulse to the WD. Read Moreā€¦
