Battery Base Options

The alkaline base option includes 10 D-cell batteries with a

10 Ahr rating at 20°C. The rechargeable base option provides

an internal 7 Ahr sealed rechargeable battery that can be

trickle-charged via vehicle power, solar panels, or ac power.

For charging the battery via ac power, a 110 Vac wall charger

is offered for US customers or other countries with 110 Vac

outlets. A 100 to 240 Vac wall charger is also available. When

using vehicle power, our DCDC18R Boost Regulator is used

to increase the vehicle’s supply voltage to charging levels

required by the CR23X. The low-profile (no battery) option

requires a user-supplied dc source. It is preferred when the

system’s power consumption, (e.g. satellite transmitters)

needs a user-supplied deep-cycle battery or when it’s advan-

tageous to have a thinner datalogger.

Transient Protection

Rugged gas tubes protect the analog inputs from electrical

transients. The CR23X is Compliant under the European

Union’s EMC Directive.

Operation in Harsh Environments

Standard operating range is -25° to +50°C; an extended range

of -40° to +80°C is available. A CR23X housed in a weather-

resistant enclosure with desiccant is protected from humidity

and most contaminants.

Data Storage and Retrieval Options

Storage Modules reliably store data and datalogger programs.

The data and programs can be downloaded later to a PC.

Direct Links use the CR23X's RS-232 port to connect the data-

logger to a computer. The CR23X can be connected to the

computer over distances up to 50 feet.

Short Haul Modems provide local communications between

the CR23X and a PC with an RS-232 serial port.

Multidrop Interfaces link a central computer and up to 200

dataloggers on a single coaxial cable.

PDA Handhelds can communicate with the CR23X via a seri-

al cable and PConnect Software.

Ethernet Communication Peripherals allow the CR23X to

communicate over a local network or the Internet.

Radio Frequency (RF) Communications are supported via

UHF, VHF, or spread spectrum radios.

Telephone Networks use landlines or cellular transceivers for

communications between the datalogger and PC. Our voice-

synthesized modem transmits the CR23X’s data by voice.

Satellite Transmitters transmit data via the GOES, Argos, or

INMARSAT-C satellite systems.

Channel Expandability

SDMs and multiplexers expand the already formidable mea-

surement and control capabilities of the CR23X. SDMs are

addressable peripherals that expand digital control ports, ana-

log output ports, and measurement capabilities. Multiplexers

allow sharing of switched excitation channels and analog

inputs, thereby increasing the number of sensors that can be

measured. Several SDMs or multiplexers can be connected to

one datalogger.

Software Packages

PC200W Starter Software allows you to transfer the datalog-

ger's program and collect data via a direct communications

link. PC200W is available at no charge from

http://www.campbellsci.com/resource.html

LoggerNet and PC208W are our full-feature software

packages. They support:

• Direct and telecommunications links

• Datalogger programming for most commercially available

sensors, SDMs, multiplexers, and relays

• Real-time data display

• Report generation

Real-Time Data Monitor (RTDM) allows experienced users to

create custom graphic screens. RTDM supports automatic

generation of JPEG output for Internet display. A similar soft-

ware package, RTDMRT, was developed for customers who

require display-only capability. RTDMRT allows you to dis-

play screens that were created using RTDM.

Peripherals and Software

CR23X-based systems typically include a data retrieval option and may include measurement and control peripherals.

Our software supports datalogger programming, communications between the CR23X and PC, and data display.

A GOES

satellite system

provides data

retrieved from a

weather station on

Nevado Sajama,

Bolivia, to climate

researchers in the

United States.
