1.9 Connectors
and Wiring
(pinout)
The pinout of the DB-37 37-pin female connector for the DNx-DIO-470 board is
shown in Figure 1-3.
Figure 1-3 DB-37 I/O Connector Pinout for DIO-470
For software compatibility with other UEI DIO products, the 10 output groups of
the DIO-470 are numbered from NO-0, NC-0, COM-0 through NO-9, NC-9,
COM-9. Note that the output of each channel is a set of three pins for NC con-
tacts, NO contacts, and COM.
Before plugging any I/O connector into the Cube or board, be sure
to remove power from all field wiring. Failure to do so may cause
severe damage to the equipment.
1.10 Fuses The COM connection of each DIO-470 channel is protected by a 7 A fuse. 
The fuse part number is FUSE 7A125V 6125 FAST SSQ.
Fuses can be replaced by lifting the blown fuse out of the fuse block (with
tweezers) and inserting a new one.
Fuses for channels 0 through 9 correspond to “FA0” through “FA9” labeling on
the board.
1.11 Anti-kickback
Diodes The DIO-470 can drive solenoids, motors, or other high-current inductive loads.
An anti-kickback diode must be installed (with attention to polarity) on relay
outputs to avoid voltage kickback into the DIO-470 board and other control
circuitry.
Use of the DIO-470 to drive inductive loads requires installation of anti-kickback
diodes on each output. Installation of these diodes is the responsibility of the
user. Failure to provide these diodes can cause damage to components of the
board.

United Electronic Industries, Inc.
Chapter 2 Programming with the High Level API
This chapter provides the following information about using the UeiDaq 
high-level FrameworkAPI for DNx-DIO-470 programming:
•About the High-level Framework (Section 2.1)
•Creating a Session (Section 2.2)
•Configuring the Resource String (Section 2.3)
•Configuring for Digital I/O (Section 2.4)
•Configuring the Timing (Section 2.5)
•Writing Data (Section 2.6)
•Cleaning-up the Session (Section 2.7)
2.1 About the
High-level
Framework
UeiDaq Framework is object oriented and its objects can be manipulated in the
same manner from different development environments, such as Visual C++,
Visual Basic, or LabVIEW.
UeiDaq Framework is bundled with examples for supported programming
languages. Examples are located under the UEI programs group in:
•Start » Programs » UEI » Framework » Examples
The following sections focus on the C++ API, but the concept is the same no
matter which programming language you use.
Please refer to the “UeiDaq Framework User Manual” for more information on
use of other programming languages.
2.2 Creating a
Session The Session object controls all operations on your PowerDNx device. Therefore,
the first task is to create a session object:
2.3 Configuring
the Resource
String
UeiDaq Framework uses resource strings to select which device, subsystem
and channels to use within a session. The resource string syntax is similar to a
web URL:
<device class>://<IP address>/<Device Id>/<Subsystem><Channel list>

For PowerDNA and RACKs, the device class is pdna.
For example, the following resource string selects digital output lines 0,1,2,3 on
device 1 at IP address 192.168.100.2: “pdna://192.168.100.2/Dev1/Do0:3”
// create a session object
CUeiSession session;

2.4 Configuring
for Digital I/O The DIO-470 can be configured for digital output.
NOTE: In Framework, a digital channel corresponds to a physical port on the
device. You cannot configure a session only to access a subset of lines
within a digital port.
NOTE: Sessions are unidirectional.The DIO-470 is also unidirectional, and you
only need to configure one session for output.
The following snippet configures the digital ports of a DIO-470 set as device 1:
2.5 Configuring
the Timing You can configure the DIO-470 to run in simple mode (point by point).
In simple mode, the delay between samples is determined by software on the
host computer.
The following sample shows how to configure the simple mode. Please refer to
the “UeiDaq Framework User’s Manual” to learn how to use other timing modes.
2.6 Writing Data Writing data is done using a writer object.
The following sample shows how to create a writer object and write data:
2.7 Cleaning-up
the Session The session object will clean itself up when it goes out of scope or when it is
destroyed. To reuse the object with a different set of channels or parameters,
you can manually clean up the session as follows:
// Configure session to write to ports 1 to 3 on device 1
session.CreateDOChannel(“pdna://192.168.100.2/Dev1/Do1:3”);
// configure timing for point-by-point (simple mode)
session.ConfigureTimingForSimpleIO();
// create a writer and link it to the session’s stream
CUeiDigitalWriter writer(session.GetDataStream());
// to write a value, the buffer must contain one value per channel
uInt32 data = 0x3FE;
// write one scan, the buffer must contain one value per channel
writer.WriteSingleScan(&data);
// clean up the session
session.CleanUp();

Chapter 3 Programming with the Low-Level API
This chapter provides the following information about programming the DIO-470
using the low-level API:
•About the Low-level API (Section 3.1)
•Low-level Functions (Section 3.2)
•Low-level Programming Techniques (Section 3.3)
3.1 About the
Low-level API The low-levelAPI provides direct access to the DAQBIOS protocol structure and
registers in C. The low-levelAPI is intended for speed-optimization, when
programming unconventional functionality, or when programming under Linux or
real-time operating systems.
When programming in Windows OS, however, we recommend that you use the
UeiDaq high-level FrameworkAPI (see Chapter 2).The Frameworkextendsthe
low-level API with additional functionality that makes programming easier and

3.3 Low-level
Programming
Techniques
Application developers are encouraged to explore the existing source code
examples when first programming the DIO-470. Sample code provided with the
installation is self-documented and serves as a good starting point.
Code examples are located in the following directories:
•On Linux systems: <PowerDNA-x.y.z>/src/DAQLib_Samples
•On Windows: Start » All Programs » UEI » PowerDNA » Examples
Sample code for data acquisition modes have the name of the I/O boards being
programmedembeddedinthesamplename. For example,Sample470contains
sample code for running the an DIO-470 using immediate mode.
3.3.1 Data
Collection
Modes
The DIO-470 supports the Immediate (point-to-point) acquisition mode, which
provides easy access to a single I/O board at a non-deterministic pace.
Immediate mode acquires or sets a single data point per channel and runs at a
maximum of 100 Hz.
API that implement data acquisition modes and additional mode descriptions
are provided in the PowerDNAAPI Reference Manual.
