The DaqBoard/3000 Series boards feature a 16-bit/1-MHz A/D converter, 16 analog input channels [user
expandable up to 64], up to four 16-bit/1-MHz analog outputs, 24 high-speed digital I/O channels, 2 timer
outputs, and four 32-bit counters.

All analog I/O, digital I/O, and counter/timer I/O can operate synchronously and simultaneously,
guaranteeing deterministic I/O timing amongst all signal types. The DaqBoard/3000 Series boards include
a high-speed, low-latency, highly deterministic control output mode that operates independent of the PC. In
this mode both digital and analog outputs can respond to analog, digital and counter inputs as fast as 2µsec.

Other Hardware Features Include:

o Encoder measurements up to 20 MHz, including Z-channel zeroing
o Frequency and Pulse-width measurements with 20.83 nsec resolution
o Timing mode: can measure the time between two counter inputs to 20.83 nsec resolution
o Self-calibration

The DaqBoard/3000 series offers up to 12-MHz scanning of all digital input lines. Digital inputs and
counter inputs can be synchronously scanned [along with analog inputs] but do not affect the overall A/D
rate because they use no time slot in the scanning sequencer. For example, one analog input can be scanned
at the full 1-MHz A/D rate along with digital and counter input channels. The 1-MHz A/D rate is
unaffected by additional digital and counter channels.

Adding analog input channels to a DaqBoard/3000 Series board is easy. An additional 48 single-ended
[or 24 differential] analog input channels can be added to each board with the optional PDQ30 expansion
module.* The PDQ30 connects to the Daqboard/3000 series card via an external cable. With the
DaqBoard/3000’s 1-MHz aggregate sample rate, users can easily add multiple analog expansion channels
and still have enough bandwidth to have a per-channel sample rate in the multiple kHz range.

DaqBoard/3006 does not support PDQ30.

DaqBoard/3000 Series User’s Manual 988093 Daq Systems and Device Overviews 1-3

Signal I/O

One 68-pin connector provides access to the 16SE/8DE analog input channels, 24 digital I/O lines,
counter/timer channels, and analog outputs (when applicable). With exception of DaqBoard/3006, a
HDMI connector is also located on the orb. The HDMI provides connection for channel expansion with
the PDQ30.

Analog Input

The DaqBoard/3000 series has a 16-bit, 1-MHz A/D coupled with 16 single-ended, or 8 differential
analog inputs. Seven software programmable ranges provide inputs from ±10V to ±100 mV full scale [with
exception of DaqBoard/3006 which has a fixed single-ended range of ±10V.] Each channel can be
software-configured for a different range, as well as for single-ended or differential bipolar input.

Synchronous I/O

The DaqBoard/3000 series has the ability to make analog measurements and scan digital and counter
inputs, while synchronously generating up to four analog outputs.

Additionally, while digital inputs and counter inputs can be synchronously scanned along with analog
inputs, they do not affect the overall A/D rate because they use no time slot in the scanning sequencer. For
example, one analog input can be scanned at the full 1-MHz A/D rate along with digital and counter input
channels. The 1-MHz A/D rate is unaffected by the additional digital and counter channels.

Orb with HDMI and 68-Pin SCSI Connectors

Note: The HDMI connector is not present on the DaqBoard/3006.

Input Scanning

DaqBoard/3000 Series devices have several scanning modes to address a wide variety of applications. A
512-location scan buffer can be loaded by the user with any combination of analog input channels. All
analog input channels in the scan buffer are measured sequentially at 1 µsec per channel. The user can also
specify that the sequence repeat immediately, or repeat after a programmable delay from 0 to 19 hours,
with 20.83 nsec resolution. For example, in the fastest mode, with a 0 delay, a single analog channel can
be scanned continuously at 1 Msamples/s; two analog channels can be scanned at 500K samples/seach;
16 analog input channels can be scanned at 62.5 Ksamples/s.

The digital and counter inputs can be read in several modes. First, via software the digital inputs or
counter inputs can be read asynchronously at anytime before, during, or after an analog input scan
sequence. This software mode is not deterministic as to exactly when a digital or counter input is read
relative to an analog input channel.

In either of the two synchronous modes, the digital inputs and/or counter inputs are read with deterministic
time correlation to the analog inputs. In the once-per-scan mode, all of the enabled digital inputs and
counter inputs are read during the first analog measurement of an analog input scan sequence. The
advantage of this mode is that the digital and counter inputs do not consume an analog input time slot, and
therefore do not reduce the available bandwidth for making analog input measurements. For example,
presume all 24 bits of digital input are enabled, and all four 32-bit counters are enabled, and eight channels
of analog inputs are in the scan sequence at full 1µsec/channel rate. At the beginning of each analog input
scan sequence, which would be 8 µsec in total duration, all digital inputs and counter inputs will be
measured and sent to the PC during the first µsec of the analog scan sequence.

1-4 Daq Systems and Device Overviews

988093 DaqBoard/3000 Series User’s Manual

Another synchronous mode allows digital inputs to be scanned every time an analog input channel is
scanned. For example, if eight analog inputs are scanned at 1 µsec per channel continuously, and 24 bits of
digital inputs are enabled, then the 24 bits of digital inputs will be scanned at 24 bits per 1 µsec. If counters
are enabled in this mode, they will be scanned at once per scan, in the same manner as in the first example
above.

Note: It is not necessary to read counters as often as it is to read digital inputs. This is because counters

continue to count pulses regardless of whether or not they are being read by the PC.

Example 1: Analog channel scanning of voltage inputs

The figure below shows a simple acquisition. The scan is programmed pre-acquisition and is made up of 6
analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch25.) Each of these analog channels can have a different
gain. The acquisition is triggered and the samples stream to the PC via DMA. Each analog channel
requires one microsecond of scan time therefore the scan period can be no shorter than 6 us for this
example. The scan period can be made much longer than 6 us, up to 19 hours. The maximum scan
frequency is one divided by 6us or 166,666 Hz.

Notice that some of the analog channels in the scan group are from a PDQ30 expansion module. All
analog channels are sampled at the same rate of 1us. Analog channels on the PDQ30 can also have any of
the gain ranges applied.

DaqBoard/3000 Series User’s Manual 988093 Daq Systems and Device Overviews 1-5

Example 2: Analog channel scanning of voltage and temperature inputs

The figure below shows a more complicated acquisition. The scan is programmed pre-acquisition and is
made up of 6 analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch23.) Each of these analog channels can
have a different gain. Two of the channels (22 and 23) are from a PDQ30 expansion module. These two
channels can be programmed to directly measure thermocouples. In this mode, oversampling is
programmable up to 256 oversamples per channel in the scan group. When oversampling is applied, it is
applied to all analog channels in the scan group, including temperature and voltage channels. (Digital
channels are not oversampled.) If the desired number of oversamples is 256 then each analog channel in
the scan group will take 256 microseconds, the returned 16-bit value represents an average of 256
consecutive 1us samples of that channel. The acquisition is triggered and 16-bit values (each representing
an average of 256) stream to the PC via DMA.

Since two of the channels in the scan group are temperature channels, the acquisition engine will be
required to read a cold-junction-compensation (CJC) temperature every scan. In fact, depending upon
which PDQ30 channels are being used for temperature, there may be a CJC temperature required for each
temperature channel in the scan. Each 4 channel terminal block of the PDQ30 shares one CJC so if all
temperature channels are grouped on one (of the six) terminal blocks, then only one CJC temperature
measurement will need to be made per scan. For every PDQ30 terminal block that is measuring at least
one temperature channel, one additional CJC temperature measurement will be automatically added to the
scan group. This increases the scan period and reduces the maximum scanning frequency.

In this example, the desired number of oversamples is 256, therefore each analog channel in the scan group
requires 256 microseconds to return one 16-bit value. The oversampling is also done for CJC temperature
measurement channels. The minimum required scan period for this example is therefore 7 X 256 us or
1792 microseconds. The maximum scan frequency is the inverse of this number, 558 Hz.

Autozero may also be employed. This adds more channels to the scan group and further reduces the
maximum scan frequency. Auto zero channels read a shorted analog input that is internal to the PDQ30.
Auto zeroing reduces drift due to fluctuating ambient temperatures or ambient temperatures outside the DC
specifications.

988093 DaqBoard/3000 Series User’s Manual

Example 3: Analog and digital channel scanning, once per scan mode

The figure below shows a more complicated acquisition. The scan is programmed pre-acquisition and is
made up of 6 analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch25) and 4 digital channels (16-bits of
digital IO, 3 counter inputs.) Each of the analog channels can have a different gain and each of the counter
channels can be put into a different mode (totalizing, pulsewidth, encoder, etc.) The acquisition is
triggered and the samples stream to the PC via DMA. Each analog channel requires one microsecond of
scan time therefore the scan period can be no shorter than 6 us for this example. All of the digital channels
are sampled at the start of scan and do not require additional scanning bandwidth as long as there is at least
one analog channel in the scan group. The scan period can be made much longer than 6 us, up to 19 hours.
The maximum scan frequency is one divided by 6us or 166,666 Hz.

The counter channels could be returning only the lower 16-bits of count value if that is sufficient for the
application. They could also be returning the full 32-bit result if necessary. Similarly, the digital input
channel could be the full 24 bits if desired or only 8 bits if that is sufficient. If the 3 counter channels are
all returning 32 bit values and the digital input channel is returning a 16 bit value, then 13 samples are
being returned to the PC every scan period, each sample being 16-bits. 32-bit counter channels are divided
into two 16-bit samples, one for the low word and the other for the high word. If the maximum scan
frequency is 166,666 Hz then the data bandwidth streaming into the PC is 2.167 MSamples per second.
Some slower PCs may have a problem with data bandwidths greater than 6 MSamples per second.

DaqBoard/3000 Series User’s Manual 988093 Daq Systems and Device Overviews 1-7

Example 4: Sampling digital inputs for every analog sample in a scan group

The figure below shows another acquisition. The scan is programmed pre-acquisition and is made up of 6
analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch25) and 4 digital channels (16-bits of digital input, 3
counter inputs.) Each of the analog channels can have a different gain and each of the counter channels
can be put into a different mode (totalizing, pulsewidth, encoder, etc.) The acquisition is triggered and the
samples stream to the PC via DMA. Each analog channel requires one microsecond of scan time therefore
the scan period can be no shorter than 6 us for this example. All of the digital channels are sampled at the
start of scan and do not require additional scanning bandwidth as long as there is at least one analog
channel in the scan group. The 16-bits of digital input are sampled for every analog sample in the scan
group. This allows up to 1MHz digital input sampling while the 1MHz analog sampling bandwidth is
aggregated across many analog input channels. The scan period can be made much longer than 6 us, up to
19 hours. The maximum scan frequency is one divided by 6us or 166,666 Hz. Note that digital input
channel sampling is not done during the “dead time” of the scan period where no analog sampling is being
done either.

If the 3 counter channels are all returning 32 bit values and the digital input channel is returning a 16 bit
value, then 18 samples are being returned to the PC every scan period, each sample being 16-bits. 32-bit
counter channels are divided into two 16-bit samples, one for the low word and the other for the high word.
If the maximum scan frequency is 166,666 Hz then the data bandwidth streaming into the PC is 3
MSamples per second. Some slower PCs may have a problem with data bandwidths greater than 6
MSamples per second.

Analog Input & Channel Expansion

The DaqBoard/3000 series has a 16-bit, 1-MHz A/D coupled with 16 single-ended, or 8 differential analog
inputs. Seven software programmable ranges provide inputs from ±10V to ±100 mV full scale. Each
channel can be software-configured for a different range, as well as for single-ended or differential bipolar
input. A hybrid PGIA on the boards is guaranteed to settle to the specified accuracy while operating at the
full 1 Msample/s rate.

Adding additional analog input channels to the /3000 series boards is easy with the optional PDQ30
expansion module. The PDQ30 connects to the board via cable and does not consume a PCI slot. PDQ30
adds an additional 48 single-ended or [24 differential-ended] analog inputs for a total channel capacity of
64 single-ended [or 32 differential] inputs.

Measurement speed of PDQ30 channels is the same 1 Msample/s exhibited by the /3000 board channels.
The DaqBoard/3000 Series supports up to four boards per PC, effectively quadrupling the number of
channels.

The PDQ30 attaches via the CA-266-3 cable to the HDMI expansion connector on the orb of the
DaqBoard, with exception of the DaqBoard/3006.*

DaqBoard/3006 has no HDMI connector and is intended for small channel applications for which expansion is not a

Bus Mastering DMA

The DaqBoard/3000 series supports Bus Mastering DMA. Multiple DMA channels allow analog and
digital/counter input data, as well as analog and digital output data to flow between the PC and the
DaqBoard/3000 series without consuming valuable CPU time. The driver supplied with the
DaqBoard/3000, as well as all other third-party software support such as LabVIEW®, automatically
utilize Bus Mastering DMA to efficiently conduct I/O from the PC to the DaqBoard.

Triggering

Triggering can be the most critical aspect of a data acquisition application. The DaqBoard/3000 series
supports a full complement of trigger modes to accommodate any measurement situation.

Hardware Analog Triggering

level programmed by the user sets an analog DAC, which is then compared in hardware to the analog input
level on the selected channel. The result is analog trigger latency wh ich is guaranteed to be less than1 µs.
Any analog channel can be selected as the trigger channel, in cluding built-in or PDQ30 expansion
channels. The user can program both the trigger level, as well as the rising or falling edge and hysteresis.

Digital Triggering

latencies guaranteed to be less than 1 µs. Both the logic levels (1 or 0), as well as the rising or falling edge
can be programmed for the discrete digital trigger input.

Pattern Triggering

ability to mask or ignore specific bits.

Software-Based Channel Level Triggering

readings [analog, digital, or counter] are interrogated by the PC in order to detect the trigger event.
Triggering can also be programmed to occur when one of the counters reaches, exceeds, or is within a
programmed window.

detected on scanned digital input channel patterns as well. Normally software-based triggering results in
long latencies from the moment a trigger condition is detected until the instant data is acquired. However,
theDaqBoard/3000 Series circumvents this undesirable situation by use of pre-trigger data. Specifically,
when software-based-triggering is employed, and the PC detects that a trigger condition has occurred,
(which may be thousands of readings after the actual occurrence of the signal), the DaqBoard driver
automatically looks back to the location in memory, to where the actual trigger-causing measurement
occurred. The acquired data presented to the user begins at the point where the trigger-causing
measurement occurs. The maximum latency in this mode is equal to one scan period

Stop Trigger

. Any of the software trigger modes previously described, including scan count, can be used
to stop an acquisition. Thus an acquisition can be programmed to begin on one event, such as a voltage
level, and then can stop on another event, such as a digital pattern.

Pre-Triggering and Post-Triggering Modes

. Six modes of pre-triggering and post-triggering are
supported, providing a wide variety of options to accommodate any measurement requirement. When
using pre-trigger, the user must use software-based triggering to initiate an acquisition. Th e six modes are:

o No pre-trigger, post-trigger stop event. This, the simplest of modes, acquires data upon receipt of

the trigger, and stops acquiring upon receipt of the stop-trigger event.

h

o Fixed pre-trigger with post-trigger stop event. In t

is mode, the user specifies the number of pre-

trigger readings to be acquired, after which, acquisition continues until a stop-trigger event occurs.

o No

pre-trigger, infinite post-trigger. No pre-t

rigger data is acquired in this mode. Instead, data is
acquired beginning with the trigger event, and is terminated when the operator issues a command
to halt the acquisition.

o Fix

ed pre-trigger with infinite post-trigger. The user speci

fies the amount of pre-trigger data to
acquire, after which the system continues to acquire data until the program issues a command to
halt acquisition.

DaqBoard/3000 Series User’s Manual 988093 Daq Systems and Device Overviews 1-9

o Variable pre-trigger with post trigger stop event. Unlike the previous pre-trigger modes, this

mode does not have to satisfy the pre-trigger number of readings before recognizing the trigger
event. Thus the number of pre-trigger readings acquired is variable and dependent on the time of
the trigger event relative to the start. In this mode, data continues to be acquired until the stop
trigger event is detected. Driver support only.

Every range of a DaqBoard/3000 Series device is calibrated at the factory using a digital NIST traceable
calibration method. This method works by storing a correction factor for each range on the unit at the time
of calibration. The user can adjust the calibration of the board while it is installed in the acquisition system.
This does not destroy the factory calibration supplied with the board. This is accomplished by having 3
distinct calibration tables in the DaqBoard/3000 series on-board EPROM, one which contains the factory
cal, and two which are available for user calibration.

Digital Inputs and Outputs

Twenty-four TTL-level digital I/O lines are included in each of the DaqBoard/3000 Series boards. Digital
I/O can be programmed in 8-bit groups as either inputs or outputs and can be scanned in several modes
(see Input Scanning). Ports programmed as input can be part of the scan group and scanned along with
analog input channels, or can be asynchronously accessed via the PC at any time, including when a
scanned acquisition is occurring.

Two synchronous modes are supported when digital inputs are scanned along with analog inputs.

o Scanning digital inputs at the start of each scan sequence. In this mode the digital inputs are

scanned at the start of each scan sequence, which means the rate at which they are scanned is
dependent on the number of analog input channels and the delay period. For example, if 8 analog
inputs were enabled with a 0 delay period, then the digital inputs in this mode would be scanned at
once per 8µsec, i.e., 125 kHz.

o Scanning digital inputs synchronously with every analog input channel. In this synchronous

mode, the enabled digital inputs are scanned synchronously with every analog input channel. So in
the preceding example the digital inputs would be scanned at once per µsec, or 1 MHz. If no
analog inputs were being scanned the digital inputs could be scanned at up to 12 MHz.

Digital Outputs and Pattern Generation

Digital outputs can be updated asynchronously at anytime before, during or after an acquisition. Two of the
8-bit ports can also be used to generate a 16-bit digital pattern at up to 12 MHz. The DaqBoard/3000 Series
boards support digital pattern generation via Bus Mastering DMA. In the same manner as analog output,
the digital pattern can be read from PC RAM or a file on the hard disk. Digital pattern generation is
clocked in the same four modes as described with analog output.

The ultra low-latency digital output mode allows a digital output to be updated based on the level of an
analog, digital or counter input. In this mode, the user associates a digital output bit with a specific input,
and specifies the level of the input where the digital output changes state. The response time in this mode is
dependent on the number of input channels being scanned, and can typically be in the range of 2 to 20
µsec.

Example 5: Analog channel scanning of voltage inputs and streaming analog outputs

The figure below shows a simple acquisition. The scan is programmed pre-acquisition and is made up of 6
analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch25.) Each of these analog channels can have a different
gain. The acquisition is triggered and the samples stream to the PC via DMA. Each analog channel
requires one microsecond of scan time therefore the scan period can be no shorter than 6 us for this
example. The scan period can be made much longer than 6 us, up to 19 hours. The maximum scan
frequency is one divided by 6us or 166,666 Hz.

DaqBoard/3000 Series User’s Manual 988093 Daq Systems and Device Overviews 1-11

This example has all 4 DACs being updated and the 16-bits of digital IO. These updates are performed at
the same time as the acquisition pacer clock (also called the scan clock.) All 4 DACs and the 16-bits of
pattern digital output are updated at the beginning of each scan. Note that the DACs will actually take up
to 4 us after the start of scan to settle on the updated value. This is due to the amount of time to shift the
digital data out to the DACs plus the actual settling time of the digital to analog conversion.

The data for the DACs and pattern digital output comes from a PC-based buffer. The data is streamed
across the PCI bus to the Daqboard/3000 via DMA.

It is possible to update the DACs and pattern digital output with the DAC pacer clock (either internally
generated or externally applied.) In this case, the acquisition input scans are not synchronized to the
analog outputs or pattern digital outputs. It is possible to synchronize everything (input scans, DACs,
pattern digital outputs) to one clock. That clock can be either internally generated or externally applied.

Counter Inputs

Four 32-bit counters are built into the DaqBoard/3000 Series boards. Each of the four counters accepts
frequency inputs up to 20 MHz. The high-speed counter channels can be configured on a per-channel
basis. Possible configurations include the following modes:

Counter

o
o Period
o Pulse width
o Time between edges
o Multi-axis quadrature encoder

Reference Note:

For detailed information regarding the various counter modes refer to Chapter 5,
Counter Input Configuration Modes.

The counters can concurrently monitor time periods, frequencies, pulses, and other event driven
incremental occurrences directly from encoders, pulse-generators, limit switches, proximity switches, and
magnetic pick-ups.

As with all other inputs to the boards, the counter inputs can be read asynchronously under program
control, or synchronously as part of an analog and digital scan group based on a programmable internal
timer or an external clock source.

The boards support quadrature encoders with up to 2 billion pulses per revolution, 20 MHz input
frequencies, and x1, x2, x4 count modes. With only A-phase and B-phase signals, 2 channels are
supported. With A-phase, B-phase, and Z-index signals, 1 channel is supported.

Each input can be debounced from 500 ns to 25.5 ms (total of 16 selections) to eliminate extraneous noise
or switch induced transients. Encoder input signals must be within -15V to +15V and the switching
threshold is TTL (1.3V). Power is available for encoders, +5V at up to 500 mA.

Timer Outputs

Two 16-bit timer outputs are built into every 3000 series board. Each timer is capable of generating a
different square wave with a programmable frequency in the range of 16 Hz to 1 MHz.

asynchronously at any time. Both timer outputs can also be updated during an acquisition as the result of
setpoints applied to analog or digital inputs. See the section on pattern detection setpoints for more
information and examples.

Multiple DaqBoards per PC

The features described for DaqBoard/3000 Series boards can be replicated up to four times, as up to four
boards can be installed in a single host PC. The serial number on each board differentiates one from
another, and a user-selected name can be assigned to each board for easy recognition within the program.
When multiple boards are installed they can be operated synchronously. This is done by designating one
board as the master. The other boards [slaves] are synchronized to the master by the pacer clock which is
externally routed to the designated slave boards.

Connection Tips

CAUTION

Turn off power to the host PC and externally connected equipment prior to connecting
cables or signal lines. Electric shock or damage to equipment can result even under
low-voltage conditions.

Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)
Use care to avoid touching board surfaces and onboard components. Only handle

boards by their edges (or ORBs, if applicable). Ensure boards do not come into
contact with foreign elements such as oils, water, and industrial particulate.

System Example

A DaqBoard/3000 Series system example which includes both a PDQ30 and a DBK215 is illustrated on
page 2-4. For convenience, it has been repeated below. In regard to the PDQ30 aspect:

1) Connection from PDQ30 to DaqBoard/3000 is made via a CA-266-3 (or CA-266-6) HDMI cable.

2) PDQ30’s analog input lines connect via removable screw-terminal blocks (TB1 through TB6).

3) A pinout for PDQ30 follows shortly.

4) Users of DBK215 should refer to Appendix A.

5) Instead of connecting a DBK215 to the DaqBoard/3000 series 68-pin SCSI connector, a TB-100

terminal board option can be connected. The TB-100 option is discussed on page 2-3.

*Note: The DBK215 offers screw terminal connections and BNC connections in an enclosure. If B NC connectors and an

enclosure are not needed, a TB-100 Terminal Connector option can be connected to the 68-pin SCSI connector instead
of the DBK215. See page 2-3 for TB-100 information. Refer to Appendix A for DBK215
information.

This CAUTION symbol warns of possible equipment damage due to electrostatic
discharge. The discharge of static electricity can damage some electronic
components. Semiconductor devices are especially susceptible to ESD damage. You
should always handle components carefully, and you should never touch connector
pins or circuit compone nts unless you are follo wing ESD guidelines in an a ppr opriate
ESD-controlled area. Such guidelines include t he use of properly grounded mats and
wrist straps, ESD bags a nd cartons, and rela ted procedures.

parts. Only qualified personnel are to provide service to the devices.

User’s Manual 949290 CE-Compliance & Noise Considerations 3-1

The specific safety conditions for CE compliance vary by product; but general safety conditions include the
following bulleted items:

• The operator must observe all safety cautions and operating conditions specified in the

documentation for all hardware used.

• The host computer and all connected equipment must be CE compliant.

• All power must be off to the device and externally connected equipment before internal access to the

device is permitted.

• Ensure that isolation voltage ratings do not exceed documented voltage limits for power and signal

inputs. All wire insulation and terminal blocks in the system must be rated for the isolation voltage
in use. Voltages above 30 Vrms or ±60 VDC must not be applied if any condensation has formed on
the device.

• Current and power use must not exceed specifications. Do not defeat fuses or other over-current

protection.

Emissions/Immunity Conditions

The specific immunity conditions for CE compliance vary by product. General immunity conditions include the
following:

• Cables must be shielded, braid-type with metal-shelled connectors. Input terminal connections are to be

made with shielded wire. The shield should be connected to the chassis ground with the hardware provided.

• The host computer must be properly grounded.

• In low-level analog applications some inaccuracy is to be expected when I/O leads are exposed to RF fields

or transients, as noted on the Declaration of Conformity, if applicable to the device.

CE Rules of Thumb

The IOtech device is CE Compliant at the time it leaves the factory and should remain in compliance as long as the

conditions stated on the Decla ra tion of Conformity continue to be met.

A few general rules of thumb:

• Use short cables.

• When assembling or disassembling components, take ESD precautions,

including the use of grounded wrist straps.

• Ensure that the host computer is CE Compliant.

• Review the most recent Declaration of Conformity.

• Ensure all system components are properly grounded.
