Operating System/Logic Control

 e on-board operating system includes measurement,

processing, and output instructions for programming

the datalogger.  e programming language, CRBASIC,

uses a BASIC-like syntax. Measurement instructions

speci c to bridge con gurations, voltage outputs, thermo-

couples, and pulse/frequency signals are included.

Processing instructions support algebraic, statistical,

and transcendental functions for on-site processing.

Output instructions process data over time and control

external devices.  ese instructions include averages,

maximums, minimums, standard deviation, histograms,

rain ow histograms, level crossings, and FFTs.

Enclosure Options

8253 Fiberglass Environmental Enclosure

 e environmental enclosure is designed for  eld applica-

tions where the enclosure will be exposed to the elements.

A CR9000X housed in this enclosure is protected from

water, dust, and most environmental pollutants.

8255 Lab Enclosure

 e Lab Enclosure is for applications where the

CR9000X will reside inside a building.

Measurement and Control Peripherals

 e following peripherals expand the capabilities of

the CR9000X series:

• AM25T Multiplexer increases the number of ther-

mocouples/voltages that can be measured. Combi-

nations of both can be made on each AM25T.

• SDM-CAN Interface allows the datalogger to

sample data directly from a CANbus network.

• SDM-INT8 Eight Channel Interval Timer ex-

pands the number of pulse channels in the sys-

tem and outputs period, pulse width, frequency,

counts, and interval time.

• SDM-SIO4 Serial Input/Output Module pro-

vides four con gurable serial RS-232 ports for

connectingour GPS sensor or other devices that

transfer data in a serial manner.

Although the following peripherals do not support the

maximum measurement rate, the CR9000X series is

also compatible with:

• SDM-CD16AC 16-Channel AC/DC Relay Controller

• SDM-CVO4 4-Channel Current/Voltage

Output Module

• AM16/32B Multiplexer

Data Storage and Retrieval

Data storage and retrieval options commonly used

with the CR9000X series include:

• PCMCIA Cards or CompactFlash® (CF) Cards

can be used to augment the datalogger’s storage

capacity or to transport data or programs from the

datalogger to a PC.

• Ethernet Cables connected to the on-board 10baseT/

100baseT port transmit data to a PC with an Ethernet

port via a local network or the Internet.

• PC or laptop can be connected directly to the dat-

alogger’s RS-232 port (no interface required).  is

port provides electrical isolation. Alternatively, the

PC or laptop can be connected to the CR9000X’s

CS I/O port via an SC32B or SC-USB interface.

Although the following peripherals do not support the

maximum measurement rate, the CR9000X series is

also compatible with:

• Telephone modems (landline and cellular)

• Spread spectrum radios

The SDM-CAN allows a vehicle’s on-board diagnostic system to

output standardized data streams that are synchronized with

other measurements and stored in the CR9000X.

The CR9000XC includes a non-corrosive, sealed, aluminum

enclosure that provides protection from water, dust, and most

environmental pollutants.
