About the Product

This product is a PCI bus supported board that extends the analog signal input functions of a PC.
Equipped with four channels of 16bit analog input, this product is an individual isolation model that
provides isolation for the bus line with PC and between channels. Voltage input and current input are
set for each channel by jumper, while the voltage range is set by software. Windows/Linux driver is
bundled with this product.

Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.

Features

- Analog input 4channel, 16bit-resolution, conversion speed 20μ sec[50KSPS] /ch
This product has the Analog input (4channel, 16bit, 20μ sec[50KSPS] /ch).

Additionally, the voltage input/current input switch is set by jumper and current range (voltage : ±10V,
±5V, 0 - +10V, 0 - +5V) is set by software for each channel.

- Individual isolation model that provides isolation for the bus line with PC and between channels.
The isolation amplifier provides electric isolation between channels as well as between the inside of the

board (PC) and the input circuit. This allows signals with different ground levels to be input to the
channels. The isolation voltage is 500V.

- Control of sampling start/stop can be selected by software, comparison of converted data, external
trigger or other factor.

Control of sampling start can be selected by software, comparison of converted data, or external trigger
(timing of a control signal entered from outside).
Control of sampling stop can be selected forcibly by completion of sampling sessions, comparison of
converted data, external trigger, or software.

A sampling cycle can be selected from the internal clock (high precision timer mounted on the board) or
an external clock (control signal entered from outside).

- Windows/Linux compatible driver libraries are attached.

Using the attached driver library API-PAC(W32) makes it possible to create applications of
Windows/Linux. In addition, a diagnostic program by which the operations of hardware can be
checked is provided.

- LabVIEW is supported by a plug-in of dedicated library VI-DAQ.

2. Setup

Step 3 Installing the Hardware

Windows needs to detect the I/O address and interrupt used by the board. This is called hardware
installation.

When using more than one board, install the boards one at a time and do not install the next board until
setup is complete for the previous board.

Turning on the PC

Turn on the power to your PC.

CAUTION

- The board cannot be properly installed unless the resources (I/O addresses and interrupt level) for
the board can be allocated. Before attempting to install the board, first determine what PC
resources are free to use.

- The resources used by each board do not depend on the location of the PCI bus slot or the board
itself. If you remove two or more boards that have already been installed and then remount one of
them on the computer, it is unknown that which one of the sets of resources previously assigned to
the two boards is assigned to the remounted board. In this case, you must check the resource
settings.

Setup Troubleshooting

Symptoms and Actions

The board cannot be initialized. [Windows NT 4.0]
The driver may not yet be activated. When your PC is running under Windows NT 4.0, set the PnP OS

option in the BIOS Setup menu to “NO”.
For details on BIOS settings, refer to the user’s guide for your PC.

The board cannot input or output data normally

- Run the Diagnosis Program to check whether the board has been registered correctly and whether
any initialization error has occurred.

- Check the settings and connections of the board. Also check the input and output ranges. When
your board uses jumpers to set the input/output ranges, correct data cannot be obtained unless the
ranges have been adjusted. When no connection has been made, input data remains indeterminate.
The channel to be used must be wired. The channels not to be used must be connected to the
analog ground.

- If there is no appropriate signal source available at voltage input, either connect a cell or connect
the channel to the analog ground to check for 0V.

The board works with the Diagnosis Program but not with an application.
The Diagnosis Program is coded with API-TOOL functions. As long as the board operates with the

Diagnosis Program, it is to operate with other applications as well. In such cases, review your program
while paying attention to the following points:

- Check the return values of functions.

- Check the Driver No. and Board No.

The OS won't normally get started or detect the board.
[Windows Vista, XP, Server 2003, 2000]

Turn off the power to your PC, then unplug the board. Restart the OS and delete the board settings of
API-TOOL Configuration. Turn off the PC again, plug the board, and restart the OS. Let the OS detect
the board and use API-TOOL Configuration to register board settings.

Surge Voltage Countermeasures

When connecting a load that generates surge voltages and inrush currents, such as an induction load
(relay coil) or an incandescent light bulb, to the digital output, appropriate protection must be provided
in order to prevent damage to the output stage or a malfunction due to noise. The rapid shutoff of a
coil, such as a relay, generates a sudden high-voltage pulse. If this voltage exceeds the voltage
tolerance level of the output transistor, it can cause the transistor to gradually deteriorate, or even
completely damage the transistor. Therefore, when driving an induction load, such as a relay coil, you
should always connect a surge-absorbing device. The following illustrates a surge voltage
countermeasure that can be employed:

4. Functions

1. Setting the Conversion Conditions

First, set the conditions for executing analog input.

Resolution
“Resolution” signifies the number of bits used by an analog input device to represent analog signals.

The higher the resolution, the more finely the voltage range is segmented, allowing the device to
convert analog values to digital equivalents more precisely.
A device with a resolution of 12bit divides the range width into 4096 segments.
When the device covers the range of 0 - 10V, the minimum unit of converted voltages is
10÷4096≈2.44mV.
If the device has a resolution of 16bit, it is 10÷65536≈0.153mV instead.

AI-1604CI2-PCI : The resolution is 16bit.

Input Mode
Input mode of this product is single-ended input. There is no necessity for setting by software.

Channel
“Channel” represents individual channel No. for analog input signal.

For channel No., see “How to connect the connectors” - “Connector Pin Assignment” in Ch apter 3
"External Connection".
For the channel selection, specify the channel No. or the number of channel which you want to convert A
into D (channel consecutive from channel 0)

AI-1604CI2-PCI

46

4. Functions

Channel conversion order
Normally, when converting more than one channel during one sampling session, the channels are

converted starting from channel 0, as shown below.
The channel conversion order for this product is fixed. It does not require any software setting.

Range
“Range” means the range of voltages at which analog input can be performed.

The input range can be selected by setting the upper and lower input signals.
AI-1604CI2-PCI : The range is specified by setting both the jumpers and software.

Please refer to the “Chapter2 Setup - Setting the Hardware - Setting the Analog Input”.

Memory
Device’s or driver’s input data storage memory is used to enable advanced analog input processing at

high speed. For the memory, the FIFO or ring format can be selected by means of software.
AI-1604CI2-PCI : The product uses the memory for storing converted data on the driver.

- FIFO format
In the FIFO (First In First Out) format, input data items are read from memory in the same order in
which they were written to the memory. Input data items are fed out of the memory sequentially,
where the oldest one is always read from the memory. The status monitor and application
notification functions are provided, which check and report the state in which the memory has
stored a fixed amount of data or in which the memory has become full.
The FIFO memory is used to obtain all input data from analog input in a short or infinite period of
time.

AI-1604CI2-PCI

47

4. Functions

- Ring format
In the ring format, the memory contains storage areas arranged in a ring. Input data items are
written to the memory sequentially. When it stores data exceeding the limit, it overwrites the area
storing the previous item of input data. The status monitor and application notification functions
are provided, which check and report the state in which data has been written to certain areas of
memory.
The ring memory is used to obtain data where conversion has stopped due to some event, usually
without obtaining data in the normal state.

AI-1604CI2-PCI

48

4. Functions

Repeat
“Repeat” indicates the number of repetitions of sampling to be executed, from when the sampling start

condition is satisfied until the end of sampling, including delayed sampling.
The number of repetitions is set by means of software, for which conversion is repeated. You can set
an infinite number of repetitions, in which case the conversion is terminated by the software abort
command.
Input data items are stored to the memory sequentially. The repetition state can be subject to status
monitoring and application notification.

This product does not support the Repeat feature when the sampling start condition is "software".

Clock
The sampling clock controls the sampling frequency. You can select both the internal sampling clock and

the external sampling clock. The sampling clock is selected by means of software.

- Internal sampling clock
The clock signal from the device clock generator is used.

- External sampling clock
The edge of the digital signal input from an external device is used for the sampling clock.

AI-1604CI2-PCI

49

4. Functions

Start Condition
The condition for controlling the start of sampling can be selected from among software, input data

comparison and an external trigger. The conditions for controlling the start and stop of sampling are
completely independent of each other; they can be set separately.

- Software
This product starts sampling and storing input data to memory immediately after the operation start
command is issued.

- Input data comparison
When the operation start command is issued, this product compares the analog signal input through
a specified channel to the value of the preset comparison level. If the analog signal satisfies the
condition, this product starts storing input data.
Level comparison conditions are set as two conditions: level and direction.

The above sketch shows that the level comparison condition is satisfied in the rising direction.

The start condition is satisfied when the analog signal at the specified channel passes the
comparison level in the rising direction. Input data items are stored to memory, starting with those
at solid dots.

The above sketch shows that the level comparison condition is satisfied in the falling direction.

The start condition is satisfied when the analog signal at the specified channel passes the
comparison level in the falling direction. Input data items are stored to memory, starting with

4. Functions

Stop Condition
The condition for controlling the stop of sampling can be selected from among the last sampling count,
input data comparison, an external trigger, and software abort.
This product stops sampling whenever an error occurs irrespective of the stop condition setting.

- Last sampling count
This product stops sampling after storing input data to memory for the specified number of times of
sampling.

- Input data comparison
Once this product has started sampling, it compares the analog signal input through a specified
channel to the value of the preset comparison level. If the analog signal satisfies the condition,
this product stops sampling.
Level comparison conditions are set as two conditions: level and direction.

The above sketch shows that the level comparison condition is satisfied in the rising direction.

The stop condition is satisfied when the analog signal at the specified channel passes the
comparison level in the rising direction. Input data items are stored to memory, ending until those
at solid dots.

The above sketch shows that the level comparison condition is satisfied in the falling direction.

The stop condition is satisfied when the analog signal at the specified channel passes the
comparison level in the falling direction. Input data items are stored to memory, ending until
those at solid dots

If you set the level comparison directions to both directions, the start condition is satisfied when the

analog signal passes the level both in the rising and falling directions.

- External trigger
This product starts waiting for an external control signal after the specified number of samples have
been performed. Sampling stops when the external control signal (falling edge) is input.

- Software
Sampling continues indefinitely in this mode. Sampling only stops in response to a sof tware
command or an error.

AI-1604CI2-PCI

51

4. Functions

Delay
Delayed sampling is performed after the sampling stop condition is satisfied.

When a sampling stop condition other than the software about command is satisfied, this product
performs sampling for the specified number of times of delayed sampling to store input data to memory.
If you set the number of times of delayed sampling to 0, this product stops sampling the moment the
sampling stop condition is satisfied.

Event
“Event” works as a function for reporting the occurrence of a certain product state to the application.

The following events can be used in combination depending on the specifications and purpose of the
application.

- “AD conversion start condition satisfied” event
This event occurs when the AD conversion start condition is satisfied. The event is nullified when
the conversion start condition is “software”.

- “Repeat end” event
This even occurs whenever a repetition is completed.

- “End of device operation” event
This event occurs when the entire operation including repetitions is completed.

- “Stored specified sampling times” event
This event occurs when sampling has been performed for the number of times set by software.

- Overflow event
This event occurs at an attempt to store input data with the memory full.

- Sampling clock error event
This event occurs when conversion stops as an error occurs due to a sampling clock period that is
too short.

- AD conversion error event
This event occurs when conversion stops due to an AD conversion error.

2. Starting/Stopping Operation

Sampling is started by the software command.
Once started, sampling can be stopped by the software command at any timing.

4. Functions

3. Monitoring the Status and Acquiring Data

Software commands are used to monitor the operation status of the device and to acquire input data
from memory. Status monitoring and data acquisition can be performed even during sampling.

Status
The current state of the device can be checked by obtaining the device status.

The following types of device status are available:

- Device operating
The “device operating” status remains ON, after the execution of the sampling start command until
this product completes conversion, aborts operation due to an error, or stops sampling in response
to the command.

- Waiting for start trigger
This status remains ON, after this product starts sampling until the start trigger is input, if the
conversion start condition is an external trigger or level comparison. The status is set to OFF
when the input trigger is input to start conversion.
The status is set to ON whenever this product enters the conversion start wait status even when
repeated operation has been set.

- Specified sampling data stored
This status is set to ON when input data stored in memory has reached the amount corresponding to
the preset number of times of sampling.
If the memory format is FIFO, the status is set to OFF when the amount of input data in the memory
falls below the value corresponding to the preset number of times of sampling as data is acquired.
Once the status is set to ON when the memory format is ring, it remains ON until it is reset.

- Overflow
An overflow error occurs when an attempt is made to store input data to memory while it has been
full of input data.
When the memory format is FIFO, this product stops conversion.
When the memory format is ring, this product continues conversion while overwriting existing data
with new one.

- Sampling clock error
This error occurs when the sampling clock period is too short.

- AD conversion error
If the “device operating” status remains ON (without terminating conversion) for an extended
period of time, the driver regards that state as an operation error and sets this status to ON. This
error stops sampling.

Sampling
The number of sampled items of input data stored in memory can be obtained by the software

command.

Repeat
The current repeat count can be obtained by the software command.

AI-1604CI2-PCI

53

4. Functions

Data acquisition
The conversion data stored in memory can be retrieved using a software command.

The figure below shows the correspondence between the sampling count and the conversion channel for
the conversion data stored in memory.

Input data is acquired differently depending on the memory format used.

- Data acquisition in FIFO format
When FIFO memory is used, the oldest data is always read first.
The following sketch shows an image of data acquisition in FIFO format.
When data is acquired from the memory, the free memory space increases by that data size. When
data is acquired next, the oldest one of the existing data items is taken from the memory in the same
way.
The FIFO memory deletes data once that data is acquired.

AI-1604CI2-PCI

54

4. Functions

- Data acquisition in ring format
When ring memory is used, data is read always with respect to the current input data write position.
The following sketch shows an image of data acquisition in ring format.
The sampling count obtained is always the number of times of sampling for up to the latest data
(shaded portion below).
The larger the number of samples taken, the older the data item acquired first.
As the ring memory retains data even after that data is acquired, you can fetch the same data any
number of times.

4. Functions

Conversion data
The following equation represents the relationship between input data and voltage.
Voltage = Input data x (Max. range value – Min. range value) ÷ Resolution + Min. range value

The value of resolution for the 12bit device is 4096

<±10V range>
The table below shows the relationship between A-D conversion data and voltage.
