CR1000 Enhancements Over CR10X Datalogger Campbell Update 1st Quarter 2005

Hardware

Two additional differential analog input channels (four single-ended)
Range on all analog input channels increased to ±5 V
50/60 Hz rejection uses full cycle integration
Pulse inputs have 24-bit counters; maximum input frequencies do not require special configuration
Switched 12 V does not require use of control port
Custom ASIC chip gives the eight control ports the capability for:
- Pulse counting: all eight ports support direct input of high frequency signals or switch closures, low level AC possible with LLAC4
- Pairs of ports can be configured as COM ports with the capability for serial communications:
  - 300 to 115200 baud
  - Smart sensor input, no SDM-SIO4 needed
  - Short distance wired network (up to 50 feet)
  - CR1000-to-CR1000 communications
RS-232 communication interface port (not isolated) in addition to CS I/O
Parallel interface port for CompactFlash Storage Module
Standard memory equivalent to CR10X-2M, 4 M optional
Four times the processing speed
Lower quiescent current
Battery-backed clock is accurate to 3 minutes per year
