Synchronous Devices for Measurement

The SDMs are a group of addressable peripherals that expand the CR10X, 21X, CR23X, and CR7's output and measurement capabilities. The datalogger controls the SDM output device by storing a value in a memory location which is then used by the SDM to set a voltage or relay. Measurement devices store data from sensors which are regularly read into the datalogger through a control port.
