About the Board

This product is a PCI Express bus-compliant interface board that supports transfer by bus mastering and performs input/output between the external device and digital signal. This product features unisolated LVTTL level (Operating voltage : 3.3V) I/O 32channels and you can select input / output in 16 un its.
Bus master transfer makes it possible to sample quickly large data with transfer rate at 20MHz maximum. It can be used as a pattern generator that outputs arbitrary digital patterns at high speed. It can also be used as a general-purpose I/O board when bus mastering is not used.
Windows/Linux driver is bundled with this product. Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.

Features

- 32channels of unisolated LVTTL level I/O (32 input channels / each 16channels for I/O / 32 output channels are selected.)
This product has the 32channels (operating voltage 3.3VDC, positive logic) of unisolated LV TTL leve l I/O whose response speed is 50nsec. They can be used for 32bit input, 16bit input plus 16bit output, or for 32bit output.
Other than I/O bit, this product has the control signal (clock, start, stop and handshake signal (REQ, ACK) that can control starting and stopping the sampling (input) / generating (output)).
- Sampling and generating with transfer rate at 20MHz maximum
Bus master transfer makes it possible to sample (input) or generate (output) large data with transfer rate at 20MHz maximum. As the sampling and generating features have their own bus mastering blocks each made up of two independent channels, the board can generate 16 signals while sampling 16 signals.
- A synchronization control connector is provided for synchronized control of multiple boards.
A synchronization control connector is provided for synchronized control of up to 16 boards. It is also easy to synchronize operation with other CONTEC boards that have a synchronization control connector.
- You can use Max. 4 input signals as interrupt request signals at the time of using the general-purpose I/O.
You can use Max. 4 input signals as interrupt request signals and also disable or enable the interrupt in bit units at the time of using the general-purpose I/O.
- 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.

Step 3 Installing the Hardware

For using an expansion board under Windows, you have to let the OS detect the I/O addresses and interrupt level to be used by the board. The process is referred to as installing the hardware.
In the case of using two or more boards, make sure you install one by one with the Add New Hardware Wizard.

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 Express 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.

Synchronization Control Connectors

SC Connectors

Controlling simultaneous operations between boards or controlling in sync with events is in part dependent on software performance. In order to enhance the reliability of the entire system and to solve these problems, the board is equipped with SC (Synchronization Control) connectors.
Connecting the SC connectors allows boards of the same or different models to operate in sync with one another.
From the boards connected with the SC cable, select one master board and use others as slaves. On the master board, set the signal to be supplied to the slave boards with the software. On the slave boards, the signal from the master board can be set to either the pacer clock operation start or stop factor.
All board operations can also be stopped with a stop request from the master in case of an error, for example, or when requested from a slave board. A maximum of 16 boards can be connected including the master.
For more information on the setup procedure, see the driver software online help. When the SC is not connected, use the board with stand-alone settings.
Example 1: When clock start and stop requirements are set the same for multiple boards In order to synchronize master clock start and stop with slave boards you can build a synchronous
system which does not depend on software processing capabilities. If the board model is the same, data remains synchronized among boards even when channels are expanded. When board models are different, data still remains compatible since operating clock start and stop are dependent on the master.
(1) Connect the SC cable. (2) Designate master/slave with the software. (3) Assign to the connectors the clock start and stop signals to be output from the master. (4) Set up slave boards so they can utilize all signals. (5) Start in order of slave to master boards.
CAUTION
- When the clock signal is assigned to a synchronization control connector, the maximum clock frequency available is 5 MHz.
- When each signal is assigned to a synchronization control connector, the slave board causes a delay of about 100nsec.
43
Page 51
3. External Connection
Example 2: When controlling slave operations with master's internal events By outputting an internal event (interrupt) occurring on the master board, the slaves can start operating
in sync with that signal. (1) Connect the SC cable.
(2) Designate master/slave with the software. (3) Assign to the connector the event signal to be output from the master. (4) Set signals from the master to the start requirements on the slave boards. (5) Start in order of slave to master boards.

Connecting the SC Connectors (CN2,CN3)

This board is equipped with sync signal control connectors (CN2 and CN3) for connecting a sync signal cable. When the cable is connected, multiple boards can operate in sync with one another.
Connection Procedure Connect the sync signal cable when two or more boards need to operate in sync with one another.
Connect CN2 with a smaller ID number to CN3 with a greater ID number with the cable. You should only use the cable that came with the board.

4. Function

4. Function

This section describes the features of the product.

Function Outline

Overview

As this product supports transfer by bus mastering, it can be used as a pattern generator that samples or outputs arbitrary digital patterns at high speed. It can also be used as a general-purpose I/O board when bus mastering is not used.

Sampling function / generating function

This product can be used in three I/O modes: 32channels input, 16channels input/output, 32channels output. As the sampling and generating features have their own bus mastering blocks each made up of two independent channels, the product can generate 16 signals while sampling 16 sign als. For sampling and generating, this product can input and output patterns at up to 20 MHz using the internal clock. If it is too late for transfer because of failing to seize a bus, it causes an error and stops transfer because it uses bus mastering. Note that it depends, for example, on the operating status of applications on the PC whether the product can perform continuous transfer at 20 MHz. For sampling and generating, this product can input/output data in various combinations of the start, clock, and stop conditions.

Bus Master Transfer

Bus mastering by this product enables DMA for direct transfer between the product and the memory space allocated for the application when the PCI Express bus is free. For the application's memory space, a static area is specified, which is allocated by normal definition of a variable. Under the Windows operating system, memory space for applications is represented by logical addresses and physical addresses make up noncontiguous address spaces. This product transfers data continuously to the noncontiguous address space. Bus mastering enables transfer to up to 64 megabytes of physical memory space. When the area for an application to transfer data to is set, the amount of allocatable memory depends on the type of the OS and on the actual memory size of the PC.
For bus mastering, the product supports one-time transfer and ring transfer different in how it uses memory. During one-time transfer, the product completes transfer when it reaches the end of the allocated memory area. During ring transfer, the product starts transfer over again from the beginning of the allocated memory area when it reaches its end. Ring transfer continues until a stop condition is satisfied or until it is terminated by software.
45
Page 53
4. Function

Interrupt (at the time of bus master transfer)

The product provides the following two interrupt functions during bus mastering:
- Causes an interrupt each time the specified number of items are transferred.
- Causes an interrupt upon completion of transfer. These interrupts can be posted to applications by using the function of API-PAC(W32). If transfer is completed with an error when no bus can be seized or when it is missed, for example, this
product stops the transfer and generates a transfer completion interrupt. You can tell whether a transfer error has occurred by checking the status.

These types of status can be obtained by using the function of API-PAC(W32). The 32bit or 64bit transfer count can be obtained by using the function of API-PAC(W32). The transfer count is obtained as the number of data items already transferred to user application memory in input mode or as the number of data items already output to an external device in output mode.
Indicates that bus master transfer has been completed.
Indicates that PIO input/output has been started.
Indicates that PIO input/output has been stopped.
Indicates that a start signal has been input in external start mode.
Indicates that a start signal has been input twice or more in external start mode. Transfer can continue with no problem.
Indicates that the FIFO buffer is empty. This is mainly because of a heavy load on the system that makes it late for bus master transfer. Take action such as decreasing the transfer rate or system load.
Indicates that the FIFO buffer is full. This is mainly because of a heavy load on the system that makes it late for bus master transfer. Take action such as decreasing the transfer rate or system load.
Indicates a buffer overflow. The number of data items to be transferred exceeds the buffer size. Increase the buffer size. Indicates that the start and stop signals have been input at the same time in external start mode. Check how the external start and stop signals are input. Indicates that the next clock signal is input during data input in external clock. If the status is set, sampling cannot be done by using the specified external clock. Consider decreasing the period of external clock. Indicates that a stop trigger from the slave has caused forced termination. Check for any error on the slave side.
Indicates that a stop trigger from the master has caused forced termination. Check for any error on the master side.

4. Function

General-purpose I/O function

Data input

When input data is high level, [1] is input to the corresponding bit. When input data is low level, in contrast, [0] is input to the corresponding bit.

Data output

When [1] is output to the corresponding bit, [High level] is output. When [0] is output to the corresponding bit, in contrast, [Low level] is output.
CAUTION
- The entire product is set for input immediately after the power is turned on.
- It is Low level after setting to output.

Monitoring the output data

The product can read the status of the current output data without affecting the output data.
49
Page 57
4. Function

Interrupt Control Function

The product can use up to four input signals as interrupt request signals at the time of using the general-purpose I/O.
DIOA00 to DIOA03 can be used as interrupt request signals. The product can generate an interrupt request signal to th e PC when the input signal change from Low
to High.

Disabling/enabling Interrupts

Interrupt mask bits can be used to disable or enable the individual bits for interruptions. Once a certain bit has been interrupt-disabled, no interrupt occurs even when the corresponding input signal changes its level. To let interrupts occur, enable the corresponding interrupt mask bit for interruptions.
CAUTION
All of the interrupt mask bits are interrupt-disabled when the power is turned on.

Clearing the Interrupt Status and Interrupt Signal

Interrupt status bits are used to identify the input signal bit being used for requesting an interrupt. When an interrupt status is input, the interrupt request signal and the in terrupt status are cleared automatically.
CAUTION
- All of the interrupt status bits are set to 0 when the power is turned on.
- As long as the interrupt mask bit is set to disable interrupts, no interrupt status bit can be set even when the input signal changes.
