6.1.1 CRBasic Dataloggers
SDM is a Campbell Scientific communication protocol used between a
Campbell Scientific datalogger and a smart sensor. This protocol uses SDM
dedicated control ports (CR3000, CR5000, and CR9000X) or multipurpose
control ports (CR1000, CR800/850) to communicate with the CSAT3. SDM
protocol allows synchronized measurement and rapid communication between
a datalogger and the CSAT3. The CRBasic datalogger instruction, CSAT3 () is
used to communicate with the CSAT3 over the SDM bus.
6.1.2 EDLOG Dataloggers
SDM is a Campbell Scientific communication protocol used between a
Campbell Scientific dataloggers and a smart sensor. This protocol uses SDM
dedicated control ports (CR23X) or multipurpose control ports (21X or
CR10(X)) to communicate with the CSAT3. With a 21X, single ended analog
input channel 1 (labeled 1H) and a 10 K resistor is used in conjunction with
control port 1. SDM protocol allows synchronized measurement and rapid
communication between a datalogger and the CSAT3. The EDLOG datalogger
instruction, SDM-CSAT3 (P107), is used to communicate with the CSAT3
over the SDM bus.
6.1.3 CR9000
SDM communications between the CR9000 and CSAT3 is achieved via the 9
pin CSI serial I/O port on the 9080 peripheral and memory card. The CR9000
instruction CSAT3() is used to communicate with the CR9000 over the SDM
bus.
