FIGURE OV1-2. CR5000 Panel and Associated Instructions.
OV1.1.2 Signal Grounds ( )
The Signal Grounds ( ) should be used as the reference for Single-ended
Analog inputs, Excitation returns, and sensor shield wires.
Signal returns from the CAO and Pulse channels should use the
located on the CAO and Pulse terminal strip to minimize current flow through
grounds on the analog terminal strips.
the
OV1.1.3 Power Grounds (G)
The Power Grounds (G) should be used as the returns for the 5V, SW12, 12V,
and C1-C8 outputs. Use of the G grounds for these outputs with potentially
large currents will minimize current flow through the analog section, which
can cause Single-ended voltage measurement errors.
OV1.1.4 Ground Lug
The large ground lug is used to connect a heavy gage wire to earth ground. A
good earth connection is necessary fix the ground potential of the datalogger
and to send to earth transients that come in on either the G or
are shunted to ground via the spark gaps protecting other inputs.
CR5000 Overview
terminals
terminals or
OV1.1.5 Power In
The G and 12V terminals on the unplugable Power In connector are for
connecting power from an external battery to the CR5000. These are the only
terminals that can be used to input battery power; the other 12V and SW-12V
terminals are out only. Power from this input will not charge internal CR5000
batteries. Power to charge the internal batteries (17-28 VDC or 18 VRMS AC)
must be connected to the charger input on the side of the LA battery back.
OV1.1.6 Switched 12 Volts SW-12
The SW-12 terminals provide an unregulated 12 volts that can be switched on
and off under program control.
OV1.1.7 Switched Voltage Excitation (VX)
Four switched excitation channels provide precision programmable voltages
within the ±5 Volt range for bridge measurements. Each analog output will
provide up to 50 mA between ±5 V.
OV1.1.8 Switched Current Excitation (IX)
Four Switched Current Excitation channels provide precision current
excitations programmable within ±2.5 mA for resistance or bridge
measurements.
OV1.1.9 Continuous Analog Outputs (CAO)
Two Continuous Analog Outputs (CAO) with individual outputs under
program control for proportional control (e.g., PID algorithm) and waveform
generation. Each analog output will provide up to 15 mA between ±5 V.
OV-3
CR5000 Overview
OV1.1.10 Control I/O
OV1.1.11 Pulse Inputs
OV1.1.12 Power Up
There are 8 digital Input/Output channels (0 V low, 5 V high) for frequency
measurement, digital control, and triggering.
Two Pulse input channels can count pulses from high-level (5 V square wave),
switch closure, or low-level A/C signals.
The CR5000 allows shutting off power under program control. The Power Up
inputs allow an external signal to awaken the CR5000 from a powered down
state (PowerOff, Section 9). When the CR5000 is in this power off state the
ON Off switch is in the on position but the CR5000 is off. If the "<0.5 " input
is switched to ground or if the ">2" input has a voltage greater than 2 volts
applied, the CR5000 will awake, load and run the “run on power-up” program.
If the "< 0.5" input continues to be held at ground while the CR5000 is
powered on and goes through its 2-5 second initialization sequence, the
CR5000 will not run “run on power-up” program.
OV1.1.13 SDM Connections
The Synchronous Device for Measurement (SDM) connections C1,C2, and C3
along with the adjacent 12 volts and ground terminals are used to connect
SDM sensors and peripherals.
OV1.2 Communication and Data Storage
OV1.2.1 PCMCIA PC Card
One slot for a Type I/II/III PCMCIA card. The keyboard display is used to
check card status. The card must be powered down before removing it. The
card will be reactivated if not removed.
CAUTION
OV1.2.2 CS I/O
OV1.2.3 Computer RS-232
Removing a card while it is active can cause garbled data
and can actually damage the card. Do not switch off the
CR5000 power while the card is present and active.
A 9-pin serial I/O port supports CSI peripherals.
OV-4
RS-232 Port
OV1.3 Power Supply and AC Adapter
The CR5000 has two base options the low profile without any power supply
and the lead acid battery power supply base. The low profile base requires an
external DC power source connected to the Power In terminal on the panel.
The battery base has a 7 amp hour battery with built in charging regulator and
includes an AC adapter for use where 120 VAC is available (18 VAC RMS
output). Charging power can also come from a 17-28 VDC input such as a
solar panel. The DCDC18R is available for stepping the voltage up from a
nominal 12 volt source (e.g., vehicle power supply) to the DC voltage required
for charging the internal battery.
OV2. Memory and Programming Concepts
OV2.1 Memory
The CR5000 has 2MB SRAM and 1MB Flash EEPROM. The operating
system and user programs are stored in the flash EEPROM. The memory that
is not used by the operating system and program is available for data storage.
The size of available memory may be seen in the status file. Additional data
storage is available by using a PCMCIA card in the built in card slot.
CR5000 Overview
OV2.2 Measurements, Processing, Data Storage
The CR5000 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.
Processing Task: Measurement Task:

CR5000 Overview
OV2.3 Data Tables
The CR5000 can store individual measurements or it may use its extensive
processing capabilities to calculate averages, maxima, minima, histogams,
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.
