4.6.1 What You Will Need
The following items are used in this exercise. If you do not have all of these
items, you can provide suitable substitutes. If you have questions about
compatible power supplies or serial cables, review and Power Supplies — Details
(p. 94)
or contact Campbell Scientific.
• CR800 datalogger
• Power supply with an output between 10 to 16 Vdc
•
Thermocouple, 4 to 5 inches long; one is shipped with the CR800
• Personal computer (PC) with an available nine-pin RS-232 serial port, or
with a USB port and a USB-to-RS-232 adapter

Note If the CR800 datalogger is to be connected to the PC during normal
operations, use the Campbell Scientific SC32B interface to provide optical
isolation through the CS I/O port. Doing so protects low-level analog
measurements from grounding disturbances.
