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.
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.
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 by 21 char-
acters (64 by 128 pixels). Their keyboard includes 16 characters.
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”.
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, Android Devices, and PDAs
An iOS device, an Android device, our Archer-PCON Field PC, or a
user-supplied PDA can be used to view and collect data, set the
clock, and download programs. To use an iOS or Android device,
go to the Apple Store or Google Play and purchase our LoggerLink
Mobile Apps. User-supplied PDAs require either PConnect or
PConnectCE software.
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 isola-
tion. A battery-powered laptop can be attached to the datalogger’s
RS-232 port via an RS-232 cable; no interface required.
Internet and IP Networks
The NL240 or NL201 interfaces enable the CR800-series datalogger
to communicate with a PC 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 CABLE2TP
two-twisted pair 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, cellu-
lar 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 communications
between the datalogger and a PC via a four-wire unconditioned line
(two twisted pairs).
Satellite Transmitters
Our NESDIS-certied GOES satellite transmitter provides one-way
communications from a Data Collection Platform (DCP) to a receiv-
ing station. We also oer an Argos transmitter that is ideal for high-
latitude applications.
The SC115 is a light-weight, portable instrument that ts in a pocket
allowing easy transport between the datalogger and PC.
Our GOES transmitters are used for stream stage (shown), water qual-
ity, and rainfall applications.
