Overview
The CR9000X is a modular, multi-processor system that provides precision measurement capabilities
in a rugged, battery-operated package. The system makes measurements at a rate of up to 100 K
samples/second with 16-bit resolution. The CR9000X Base System includes CPU, power supply, and
A/D modules. Up to nine I/O modules are inserted to configure a system for specific applications.
The on-board, BASIC-like programming language includes data processing and analysis routines.

communication to a PC via the built-in 10BaseT/100BaseT Ethernet port or the
RS-232 port. The CR9032 also has built-in Serial Device for Measurement
(SDM) terminals and a CSI 9-pin port for communication with Campbell
Scientific peripherals. The SDM 12 volt supply is current limited to 1.85
amps. The main processor is a 180 MHz Hitachi SH-4 microprocessor. The
module has 128 MB SDRAM and 2 MB Flash EEPROM.

CR9011 Power Supply Module and AC Adapter
The CR9011 Power Supply Module provides regulated power to the CR9000X
from the internal battery modules. It also regulates battery charging from
power supplied by the AC adapter, a DC input, or other external sources. The
AC adapter may be used where AC power is available (100 - 240 volts) to
provide power to the CR9000X and charge its batteries.

The CR9011 has a relay that allows shutting off power under program control.
The Power Up inputs allow an external signal to awaken the CR9000X from a
powered down state (PowerOff, Section 9). When the CR9000X is in this
power off state the On/Off switch is in the on position but the internal relay is
open. The power LED is not lit. If the "<0.5 " input is switched to ground or
if the ">2" input has a voltage greater than 2 volts applied, the CR9000X will
awake, load the program in memory and run. If the "< 0.5" input continues to
be held at ground while the CR9000X is powered on and goes through its 2-5
second initialization sequence, the CR9000X will not run the program in
memory. The CR9011's 12VOUT supply is current limited to 300 mA.

connectors combine with the case design to reduce temperature gradients for
accurate thermocouple measurements. Resolution on the most sensitive range
is 1.6 µV.

Overview
CR9051E Fault Protected 5 V Analog Input Module
The number of channels and measurements are the same as for the CR9050
Analog Input Module. Each input channel is fault-protected so as to permit
over-voltages between +50 V and –40 V without corruption of measurements
on other input channels. All the CR9051E input channels become open
switches when the CR9000X is powered off. The CR9051E is recommended
over the CR9050E for applications where fault voltages beyond ±9 V could
come in contact with the inputs, or when the CR9000X could be powered off
while still connected to sensors that have power applied to them. The
CR9051E supports the same instruction set as the CR9050.

The CR9058E is a 10-channel, differential input isolation module. Each

OV1.3 Communication Interfaces
The CR900X's CPU module (CR9032) has built-in RS-232 and Ethernet ports,
thus eliminating the need for expensive external communication interfaces.
Any terminal emulator program can be used to set up the CR9000X's IP
address parameters. Hyper Terminal is an example of an available terminal
emulator. The port settings should be:
Bits per Second: 115,200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: Hardware
OV-7
Overview
PC9000's Terminal Mode can also be used. Set the Comm window to your
computer’s Comm port and set the baud rate to 115200. With a serial cable
hooked between your PC's and CR9000X's RS-232 ports, press the test button
to ensure that you have established communications. Close the Comm window
and open PC9000's terminal emulator (Tools/Diagnostics/Terminal Mode).
Click in the Low Level I/O box. Press enter a few times until a CR9000>
prompt is returned. Press C and enter. The IP port configuration options will
be shown. See Sections QS1.5 and QS1.6 for additional information about
setting up the IP Port for the CR9000X and for your computer.
OV2. Memory and Programming Concepts
OV2.1 Memory
The CR9032 CPU Module in the CR9000X base system has 128 MB SDRAM
and 2 MB Flash EEPROM. The operating system, user program listing(s), and
calibration files are stored in the flash EEPROM. When the CR9000X is
powered up, the operating system, the compiled program, and any calibration
files are uploaded into SDRAM. The size of available memory may be seen in
the status file. Additional data storage is available through the use of a
PCMCIA memory card in the built-in card slot.
OV2.2 Measurements, Processing, Data Storage
The CR9000X divides a program into two tasks. The measurement task
manipulates the measurement and control hardware on a rigidly timed
sequence. The processing task processes and stores the resulting
measurements and makes the decisions to actuate controls.
The measurement task stores raw Analog to Digital Converter (ADC) data
directly into memory. As soon as the data from a scan is in memory, the
processing task starts. There are at least two buffers allocated for this raw
ADC data (more under program control), thus the buffer from one scan can be
processed while the measurement task is filling another.
When a program is compiled, the measurement tasks are separated from the
processing tasks. When the program runs, the measurement tasks are
performed at a precise rate, ensuring that the measurement timing is exact and
invariant.

OV2.3 Data Tables
The CR9000X can store individual measurements or it may use its extensive
processing capabilities to calculate averages, maxima, minima, histograms,
FFTs, etc., on periodic or conditional intervals. Data are stored in tables such
as listed in Table OV2-1. The values to output are selected when running the
program generator or when writing a datalogger program directly.

This overview points out the main PC9000 functions and where to find them.
PC9000 has extensive on-line help to guide the user in its operation. Install
PC9000 to get the details. A CR9000X is not necessary to try out the
programming and real-time display options; the demo uses canned data for
viewing. Without a CR9000X, there are no communications with the

General CR9000X & CR9000XC Specifications
We recommend that you confirm system
configuration and critical specifications with
Campbell Scientific before purchase.
Electrical specifications are valid over a -25° to +50°C range unless otherwise specified; testing over -40° to
+70°C available as an option, excluding batteries. Non-condensing environment is required. To maintain specifications, Campbell Scientific recommends recalibrating dataloggers every two years.

Sensor connections use CR9052EC Easy Connectors for CR9052DC. The Easy Connectors consist of a terminal strip that is
easily disconnected from the CR9052. Customers needing to monitor several locations intermittently have found it useful
to buy several CR9052ECs and simply move the CR9000 and on-board CR9052DC(s) between monitoring locations.
