Section 5. Overview
The CR800 is equipped with hardware ports that allow communication with other
devices and networks, such as:
• PC
• Smart sensors
• Modbus and DNP3 networks
• Ethernet
• Modems
• Campbell Scientific PakBus networks
• Other Campbell Scientific dataloggers
• Campbell Scientific datalogger peripherals
Communication ports include:
• CS I/O
• RS-232
• SDI-12
• SDM
• CPI (requires a peripheral device)
• Ethernet (requires a peripheral device)
• CS I/O Port

(p. 553).
• One nine-pin port, labeled CS I/O, for communicating with a PC or
modem through Campbell Scientific communication interfaces, modems,
or peripherals. CS I/O comms interfaces are listed in the appendix
Serial I/O Modules — List
(p. 563).
Note Keep CS I/O cables short (maximum of a few feet).
5.1.1.4.1 RS-232 Ports
Note RS-232 communications normally operate well up to a transmission
cable capacitance of 2500 picofarads, or approximately 50 feet of
commonly available serial cable.
