DA12-8(PCI) 1
Digital to Analog Output Board for PCI
8ch type
DA12-8(PCI)
*Specifications, color and design of the products are subject to
change without notice.
This product is a PCI bus-compliant interface boards that
performs digital-to-analog conversion.
This product performs D-A conversion using 8 output channels
at a conversion speed of 10 sec [100KSPS] and a resolution
of 12 bit.
Using the bundled driver library [API-PAC (W32)], you can
create Windows application software for this board in your
favorite programming language supporting Win32 API
functions, such as Visual Basic or Visual C++.
Support for unipolar and bipolar output ranges
An output range can be set for each channel by software.
Two output modes selectable
This product offers a choice of two output modes selectable.
One updates only the output voltage of a specified channel and
the other updates the output voltages of all channels.
Capable of updating the output voltage using a sampling
clock
This product can update the output voltage periodically using
the internal sampling clock or in synchronization with external
events using an external sampling clock.
Safety design to adjust output voltage to 0V when power
supply is turned on
To prevent the unstable voltage and the connected device of
D/A converter from fault and malfunctions when the power
supply is turned on, the circuit is designed to adjusts output
voltage of the analog output to 0V.
Optional units
Using optional units facilitates connections.
For more details on the option, please refer to “Cable &
Connector” or “Accessories (Option)”.

Neither connect outputs to each other. Doing either can
result in a fault.
The sections below describe how to connect the signals using
flat cable and shielded cable.
The following figure shows an example of optional flat cable
(PCA37P) connection.

The following example connects a signal source to this product
using a shielded cable such as a coaxial cable (PCC16PS)
available as an option.
Use shielded cable if the distance between this product and
external device is long or if you want to provide better
protection from noise.
Use the core of the shielded cable to connect the analog output
of CN1 to the input of the external device and use the shield
braid to connect the CN1's analog ground to the external
device's ground.

Digital Multi-Meter etc.
CAUTION
If this product and the target receive noise or the distance
between this product and the signal source is too long,
data may not be input properly.
The maximum output current-carrying capacity of the
analog output signal is ±5 mA. Check the specifications
of the target before connecting this product to it.
Do not connect any of the outputs and power outputs to the
analog or digital ground.
Do not connect the analog output signal to the other analog
output signal and output signal of external device. Doing
so may malfunction.
Do not plug or unplug the interface connector to or from
while the PC or external device power is turned on. Doing
so may malfunction.
The DA converter may cause glitches as it contains no
deglitcher.
The analog output signal may temporarily vary in output
voltage when the power is turned on or when the range is
switched. If this variation in output voltage is a problem,
insert, for example, a relay between this product and the
external device.
This section shows how to connect the control signal(“External
Trigger Input”, “Settling Busy Output” and so on) by using a flat
cable.
All the control signals are TTL level signals.
