4.1.5 SDM Channels
SDM (Serial Device for Measurement) devices expand the input and output
capacity of the CR1000. Brief descriptions of SDM device capabilities are found
in the appendix Sensors and Peripherals
.
These devices connect to the CR1000
through digital I/O ports C1, C2, and C3 C3.
4.1.6 Input Expansion Modules
Modules are available from Campbell Scientific to expand the number of input
and digital I/O ports on the CR1000. The appendix Digital I/O (Control Port)
Expansion
(p. 563)
lists available modules.
4.2 Hands-On: Measuring a Thermocouple
This tutorial is designed to illustrate the function of the CR1000. During the
exercise, the following items will be described:
• Attaching a thermocouple to analog differential terminals
• Creating a program for the CR1000
• Making a simple thermocouple measurement
• Sending data from the CR1000 to a PC
• Viewing the data from the CR1000
