Base System

CR9032 CPU Module

 is 32-bit CPU module provides system control, data

processing, and communications.  e CR9032 features

a clock speed of 180 MHz and 128 Mbytes of internal

SDRAM for data and program storage. It also includes

an RS-232 DCE port, 10baseT/100baseT port, CS I/O

port, and a PC-card slot.  e CS I/O port supports

communications with our SDM device at rates up to

115,200 bps.  e PC-card slot accepts one Type I,

Type II, or Type III PCMCIA card. CompactFlash

cards are supported with an adapter. Industrial grade

Compact-Flash cards o ered by Campbell Scienti c

store 256 Mbytes, 1 Gbyte, or 2 Gbytes of data.

Power Supply

 e power supply consists of the sealed rechargeable

battery module, universal ac adapter, and CR9011 Power

Supply Module.  e battery module has a 14 Ah rating for

the CR9000X and a 7 Ah rating for the CR9000XC.  e

batteries are recharged using the universal ac adapter, a dc

input, or another external source.

 e CR9011 module controls the current  owing to

the charging source. A relay included in the CR9011

allows the datalogger to turn the power on and o .

 is conserves power and increases the battery’s life.
