Campbell CR1000X - 2.4 Communications Ports; 2.4.1 USB Port; 2.4.2 Ethernet Port; 2.4.3 C Terminals for Communications

2.4 Communications ports
The datalogger is equipped with ports that allow communications with other devices and
networks, such as:
l Computers
l Smart sensors
l Modbus and DNP3 networks
l Ethernet
l Modems
l Campbell Scientific PakBus® networks
l Other Campbell Scientific dataloggers
Campbell Scientific datalogger communications ports include:
l CS I/O
l RS-232/CPI
l USB
l Ethernet
l C terminals
2.4.1 USB port
One USB port supports communicating with a computer through datalogger support software or
through virtual Ethernet (RNDIS), and provides 5 Vdc power to the datalogger (powering
through the USB port has limitations - details are available in the specifications). The datalogger
USB port does not support USBflash or thumb drives. Although the USB connection supplies 5 V
power, a 12 Vdc battery will be needed for field deployment.
2.4.2 Ethernet port
The RJ45 10/100 Ethernet port is used for IP communications.
2.4.3 C terminals for communications
C terminals are configurable for the following communications types:
l SDI-12
l RS-232
l RS-485
l TTL (0 to 5 V)
l LVTTL (0 to 3.3 V)
l SDM
