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 communication options can be combined—increasing the exibility,
convenience, and reliability of the communications.
Keyboard Display
The CR1000KD can be used to program the CR1000, manually initiate
data transfer, and display data. The CR1000KD displays 8 lines by 21
characters (64 by 128 pixels) and has a 16-character keyboard. Custom
menus are supported allowing customers to set up choices within the
datalogger program that can be initiated by a simple toggle or pick list.
One CR1000KD can be carried station to station in a CR1000 network.
Mountable Displays
The CD100 and CD295 can be mounted in an enclosure lid. The
CD100 has the same functionality and operation as the CD1000KD,
allowing both data entry and display without opening the enclosure.
The CD295 displays real-time data only.
iOS Devices and Android Devices
An iOS device or Android device can be used to view and collect
data, set the clock, and download programs. To use an iOS or An-
droid device, go to the Apple Store or Google Play and purchase our
LoggerLink Mobile Apps.
Direct Links
AC-powered PCs connect with the datalogger’s CS I/O port via an
SC32B or SC-USB interface. These interfaces provide optical isolation.
A battery-powered laptop can be attached to the CR1000’s RS-232
port via an RS-232 cable—no interface required.
External Data Storage Devices
A CFM100 or NL116 module can store the CR1000’s data on an
industrial-grade CompactFlash (CF) card. The CR1000 can also store
data on an SC115 2 GB Flash Memory Drive.
Short Haul Modems
The SRM-5A RAD Short Haul Modem supports communications
between the CR1000 and a PC via a four-wire unconditioned line
(two twisted pairs).
Multidrop Interface
The MD485 intelligent RS-485 interface permits a PC to address and
communicate with one or more dataloggers over the CABLE2TP
two-twisted pair cable. Distances up to 4000 feet are supported.
Internet and IP Networks
Campbell Scientic oers several interfaces that enable the CR1000
to communicate with a PC via TCP/IP.
Radios
Radio frequency (RF) communications are supported via narrow-
band UHF, narrowband VHF, spread spectrum, or meteor burst radios.
Line-of-sight is required for all of our RF options.
Telephone Networks
The CR1000 can communicate with a PC using landlines, cellular
CDMA, or cellular GPRS transceivers. A voice synthesized modem
enables anyone to call the CR1000 via phone and receive a verbal
report of real-time site conditions.
Satellite Transmitters
Satellite transmitters oered by Campbell Scientic include a
NESDIS-certied GOES transmitter, an Argos transmitter, an Iridium
transmitter, and an Inmarsat BGAN satellite IP terminal. Satellite te-
lemetry oers an alternative for remote locations where phone lines
or RF systems are impractical.
The CD100 has a
vacuum ourescent
display for respon-
sive use through a
very wide operating
temperature range.
This weather station at Denali National Park, Alaska, transmits data
via a GOES satellite transmitter.
