5.3.6 Comms Hardware — Overview
The CR800 can accommodate, in one way or another, nearly all comms options.
Campbell Scientific specializes in RS-232, USB, RS-485, short haul (twisted
pairs), Wi-Fi, radio (single frequency and spread spectrum), land-line telephone,
cell phone / IP modem, satellite, ethernet/internet, and sneaker net (external
memory).
The most common comms hardware is an RS-232 cable or USB cable. These are
short-distance direct-connect devices that require no configuration of the CR800.
All other comms methods require peripheral devices; some require that CR800
settings be configured differently than the defaults.
5.3.7 Keyboard/Display — Overview
The CR1000KD Keyboard/Display is a powerful tool for field use. The
CR1000KD, illustrated in figure CR1000KD Keyboard/Display
(p. 81), is purchased
separately from the CR800.
The keyboard/display is an essential installation, maintenance, and
troubleshooting tool for many applications. It allows interrogation and
configuration of the CR800 datalogger independent of other comms links. More
information on the use of the keyboard/display is available in Custom Menus —
Overview
(p. 82). The keyboard/display will not operate when a USB cable is
plugged into the USB port.
