The CR9000 was a modular, multiprocessor system that provided precision measurement capabilities in a rugged battery-operated package. Its Base System included a CR9031 CPU module, CR9041 A/D module, CR9011 power supply module, 2 Mbytes SRAM memory, 2 Mbytes Flash Memory, power supply module, and PC9000 Support Software for Windows. The on-board, BASIC-like programming language included data processing and analysis algorithms. Up to nine I/O modules (purchased separately) could be inserted into a CR9000 to configure a system for specific applications.

I/O Modules

Contemporary I/O modules can be used with either the CR9000 or CR9000X.


The CR9000 came with PC9000 software, which has been replaced by RTDAQ software. RTDAQ software is not compatible with the CR9000. However, customers can upgrade a CR9000 datalogger to a CR9000X datalogger by replacing the CR9000's CR9031 CPU module with the contemporary CR9032 CPU module.


Connection to a PC was accomplished via Ethernet, TLink fiber optic, parallel port, or serial interface using peripheral products. Most of these peripheral products are now retired.
