The measurement processors provide the processing power and communications for the distributed Datascan systems. The modules have an integrated 16 bit ADC, and RS232 port to connect to the host computer, and a real time RS422 network to enable other processors to be connected over a distance of 1Km.
Measurement processors can be supplied with or without inbuilt scanners or I/O. Also they can be supplied with or without a network interface.
