Setting Method

Condition is set by selecting the property window.
Set the items that need to be changed in order from the above properties.

Property window

①. Device

A list of devices that can be used with this software will be displayed in the list, so select the device you want to use.

[Mode]
②. Mode

Select Generating/Sampling.

[Clock]
③. Clock

Settings	Description
Internal clock	Perform Generating at the timing of the internal clock. In this case, set the following clock values.
External clock	Perform Generating at the timing of the external clock.
Handshake	Perform generating using handshake with external equipment.

④. Clock value

This setting takes effect when you select the internal clock as the clock.
Specify the internal clock value in the unit specified in "Clock unit".

Device name	Settable range
DIO-32DM3-PE	20nsec≦ Clock value ≦ 21sec(5nsec unit)
PIO-32DM(PCI) DIO-32DM2-PE	50nsec≦ Clock value ≦ 107sec(25nsec unit)

* If the number of transferred data exceeds the size of the FIFO of the device,
it depends on the PC, but the actual settable range is about 100ns or more.

⑤. Clock unit

Settings	Description
1s	Set the internal clock in seconds.
1ms	Set the internal clock in milliseconds.
1μs	Set the internal clock in microseconds.
1ns	Set the internal clock in nanoseconds.

[Start condition]
⑥. Start condition

Select the conditions to stop data transfer.

Settings	Description
Software	Data transfer starts unconditionally when the Start Device Operation button is pressed.
Rising edge of external trigger	After the Start Device Operation button is pressed, data transfer starts at the rising edge of the external start signal.
Falling edge of external trigger	After the Start Device Operation button is pressed, data transfer starts at the falling edge of the external start signal.

[Stop condition]
⑦. Stop condition

Select the conditions to stop data transfer.

Settings	Description
Software	When the stop button is pressed, the device operation ends. In the generating mode, the data in the range specified by "Transfer start position" and "Transfer end position" is repeatedly output. Even if other conditions are selected, it will stop when the stop button is pressed.
Rising edge of external trigger	Data transfer is stopped at the rising edge of the external stop signal.
Falling edge of external trigger	Data transfer is stopped at the falling edge of the external stop signal.
Transfer completed with specified number	Transfers data for the specified number of clocks. In generating mode, please specify "Repeat times".

⑧. Transfer start position

Specify the position of the buffer to start the transfer.

Device name	Recognized Memory	OS	Available range
DIO-32DM3-PE	-	All supported OS	0≦ Transfer start position ≦ 536,870,911 *2
PIO-32DM(PCI) DIO-32DM2-PE	The memory less than 4G Byte	All supported OS *1	0≦ Transfer start position ≦ 16,515,071 *2
	The memory more than 4G Byte	Windows10 Version 1607 or earlier	0≦ Transfer start position ≦ 262,143 *2
	The memory more than 4G Byte	Windows10 Version 1703 and later	0≦ Transfer start position ≦ 524,287 *2

⑨. Transfer stop position

Specify the position of the buffer to end the transfer.
Must be set after the transfer start position.

Device name	Recognized Memory	OS	Available range
DIO-32DM3-PE	-	All supported OS	1≦ Transfer stop position ≦ 536,870,912 *2
PIO-32DM(PCI) DIO-32DM2-PE	The memory less than 4G Byte	All supported OS *1	1≦ Transfer stop position ≦ 16,515,072 *2
	The memory more than 4G Byte	Windows10 Version 1607 or earlier	1≦ Transfer stop position ≦ 262,144 *2
	The memory more than 4G Byte	Windows10 Version 1703 and later	1≦ Transfer stop position ≦ 524,288 *2

⑩. Repeat

The data in the range specified by "Transfer start position" and "Transfer end position" is output repeatedly for the specified number of times.
To enable this setting, you need to select "Transfer completed with specified number" as the stop condition.

Device name	Available range
DIO-32DM3-PE	1≦ Repeat times ≦ (536,870,912(20000000H) ÷ ([Transfer stop position] - [Transfer start position] + 1))
PIO-32DM(PCI) DIO-32DM2-PE	1≦ Repeat times ≦ (16,777,215(FFFFFFH) ÷ ([Transfer stop position] - [Transfer start position] + 1))

[Buffer size]
⑪. Buffer size

Specify the size of the buffer for transfer. You can edit the data for the size set here.

Device name	Recognized Memory	OS	Available range
DIO-32DM3-PE	-	All supported OS	1≦ Buffer size ≦ 536,870,912 23 The maximum value is equivalent to 2Gbyte/4byte (1 data)
PIO-32DM(PCI) DIO-32DM2-PE	The memory less than 4G Byte	All supported OS *1	1≦ Buffer size ≦ 16,515,072 *2 The maximum value is equivalent to 63Mbyte/4byte (1 data)
	The memory more than 4G Byte	Windows10 Version 1607 or earlier	1≦ Buffer size ≦ 262,144 *2 The maximum value is equivalent to 1Mbyte/4byte (1 data)
	The memory more than 4G Byte	Windows10 Version 1703 and later	1≦ Buffer size ≦ 524,288 *2 The maximum value is equivalent to 2Mbyte/4byte (1 data)

*1 : If the [Memory Reclaiming] function is enabled in the BIOS settings of the PC (motherboard) on which the board is mounted, the settable range will be the same as when recognizing memory of 4 GByte or more.
*2 : Depending on how the buffer area is mapped to the physical address space, it may not be possible to set the maximum value.
*3 : For DIO-32DM3-PE, if the buffer size is set to less than 2048, the transfer rate will decrease due to hardware restrictions.
