Benefits and features

Allows up to 15 additional devices to be connected to a datalogger

Fully compliant with the RS-232/RS-485/RS-422 standards

Simple connection to Campbell Scientific dataloggers using the SDM port and communications protocol

Can collect large amounts of data without hindering other processes within the datalogger

Supports `talk-through’ mode that facilitates testing and diagnostics

Currently compatible with CR6, CR800/850, CR1000, CR3000, CR5000 and CR9000X dataloggers

Uses simple CRBasic programs

Includes transient and surge protection on the serial port interface, eliminating the need for separate transient protection

Acts as an RS-485 interface for sensors with only a digital output (e.g., sonic and road weather sensor) providing a straight-forward and low power alternative to other RS-485
