Peripherals

Data Storage and Retrieval Options

To determine the best option for your application, consider the

accessibility of your site, availability of services (e.g., cellular

phone or satellite coverage), quantity of data to collect, and

desired time between data-collection sessions.

Telephone Networks use landlines, or cellular CDMA trans-

ceivers for communications between the datalogger and PC.

Our voice-synthesized modem allows a CR10X to “speak” to

you or transmit data to a computer.

Radio Frequency (RF) Communications are supported via

UHF, VHF, spread spectrum, or meteor burst radios.

Direct Links use either an SC32B Interface or an SC-USB

Interface to provide an optically isolated connection between the

CR10X and a laptop or desktop computer. The SC32B connects

to a computer RS-232 port and the SC-USB connects to a USB

port.

PDAs can set the CR10X’s clock, monitor real-time data, retrieve

data, graph data, and transfer CR10X programs. PDAs with a

Palm

OS require PConnect software (purchased separately).

These PDAs communicate with the CR10X via a direct serial

connection, spread spectrum radio, or the SC-IRDA infrared

wireless interface. PDAs with a Windows

CE OS require

PConnectCE software (purchased separately). These PDAs com-

municate with the CR10X via a direct serial connection or spread

spectrum radio.

Short Haul Modems provide local communications between the

CR10X and a PC with an RS-232 serial port.

Multidrop Interface links a central computer to one or more

dataloggers over a distance of 4000 ft.

Satellite Transmitters transmit data via the GOES, or Argos,

satellite systems. Campbell Scientific’s SAT HDR GOES trans-

mitter has been certified by NESDIS for High Data Rates (HDR).

Ethernet Communications Peripherals allow the CR10X to com-

municate over a local network or the Internet.

Storage Modules reliably store data and datalogger programs.

This allows you to transport programs between the datalogger

and PC or use the storage modules to serve as an independent

backup of the datalogger data. The storage modules are not

compatible with the Table and Pakbus datalogger operating

systems.

CR10KD Keyboard Display programs the CR10X, manually ini-

tiates data transfer, and displays data. One CR10KD can be car-

ried from station to station in a CR10X network.

Other Displays such as the DataView Display Unit and the

DSP4 Heads Up Display can be used with the CR10X. DataView

provides a two-line, 32-character LCD that displays one real-

time value, a description, and units. The DSP4 Heads Up

Display is typically used in vehicle testing applications.

Thermocouple Reference Thermistor

Campbell Scientific offers the CR10XTCR which provides a tem-

perature reference for thermocouple measurements. It requires

one single-ended analog input channel. A cover that reduces

temperature gradients along the input terminals is included.

Channel Expandability

The already formidable measurement and control capabilities

can be expanded using CSI multiplexers and Synchronous

Devices for Measurement (SDMs). SDMs are addressable

peripherals that expand digital I/O ports, plus interval channels

analog output ports, and datalogger measurement capabilities.

Up to 16 SDMs can be connected to three CR10X control ports.

Multiplexers increase the number of sensors that can be mea-

sured by a CR10X by sequentially connecting each sensor to the

datalogger. Several multiplexers can be connected to, and con-

trolled by, a single CR10X.

Enclosures

A CR10X housed in a weather-resistant enclosure can collect

data under extremely harsh conditions. The enclosure protects

the CR10X from dust, water, sunlight, or pollutants. Typically a

12” x 14” or 16” x 18” enclosure is used. They are NEMA 4X

enclosures modified for cable entry. The enclosures attach to a

flat surface, 1.00" to 1.25" IPS pipe, or vertical mast or leg of a tri-

pod or tower. These white fiberglass-reinforced polyester enclo-

sures are UV-stabilized and reflect solar radiation, reducing tem-

perature gradients inside the housing. An internal mounting

plate is prepunched for easy system configuration and exchange

of equipment in the field. A lockable hasp adds security.

Typical field-based CR10X systems include a data retrieval option, power supply, and environmental enclosure.

Peripherals that expand the CR10X's measurement and control capabilities are also available.

A satellite transmitter provides telecommunications for remote

Argentine stations where phone lines are impractical.
