External Data Storage Device
The CR800 and CR850 can use the SC115 2-GB Flash
Memory Drive to augment onsite data storage or to
transport data between the datalogger and PC.
CD295 DataView II Display
This two-line, 32-character
LCD displays one real-time
value, a description, and
units. It is typically
mounted in an enclosure lid,
which allows customers
to view the datalogger’s
data on-site without
opening the enclosure.
Keyboard Display
Keyboard displays are used to program the datalogger,
manually initiate data transfer, and display data. Both the
CR850’s integrated keyboard display and the CR1000KD can
show 8 lines x 21 characters (64 x 128 pixels). Their keyboard
includes 16 characters. Custom menus are supported allow-
ing customers to set up choices within the datalogger pro-
gram that can be initiated by a simple “toggle” or “pick list”.
Portable Handheld Devices
A user-supplied PDA can be used to collect and display the
datalogger’s data, transfer datalogger programs, graph data
for up to two elements, and transfer the datalogger’s data to
a PC. User-supplied PDAs require either PConnect or
PConnectCE soft ware.
Direct Links
AC-powered PCs connect with the datalogger’s CS I/O port
via an SC32B or SC-USB interface. Th ese interfaces provide
optical isolation. A battery-powered laptop can be attached
to the datalogger’s RS-232 port via an RS-232 cable; no
interface required.
Ethernet
The NL100 interface enables a CR800-series datalogger
to communicate over a local network or a dedicated Internet
connection via TCP/IP.
Multidrop Interface
The MD485 intelligent RS-485 interface permits a PC to
address and communicate with one or more dataloggers
over the CABLE3CBL cable. Distances up to 4000 feet are
supported.
Radios
Radio frequency (RF) communications are supported via
narrow-band UHF, narrow-band VHF, spread spectrum, or
meteor burst radios. Line-of-sight is required for all of our RF
options.
Telephone Networks
The CR800 series can communicate with a PC using
landlines, cellular CDMA, or cellular GPRS transceivers.
A voice synthesized modem enables anyone to call
the datalogger via phone and receive a verbal report of
real-time site conditions.
Short Haul Modems
The SRM-5A RAD Short Haul Modem supports communi-
cations between the datalogger and a PC via a four-wire
unconditioned line (two twisted pairs).
Satellite Transmitters
Our NESDIS-certi ed GOES satellite transmitter provides
one-way communications from a Data Collection Platform
(DCP) to a receiving station. We also o er an Argos
transmitter that is ideal for high-altitude and polar
applications and a METEOSAT transmitter for European
applications.
Communication Options
To determine the best option for an application, consider the accessibility of the site, availability of services (e.g., cellular
phone or satellite coverage), quantity of data to collect, and desired time between data-collection sessions. Some communi-
cation options can be combined—increasing the exibility, convenience, and reliability of the communications.
Our GOES transmitters are used for stream stage (shown), water
quality, and rainfall applications.
Campbell Scientic will install a DataView II Display in the enclo-
sure lid. Alternatively, the customer can install the display.
The SC115 is a light-weight, portable instrument that ts in a
pocket allowing easy transport between the datalogger and PC.
