PowerDNA DIO-403 Layer -2-
1.1 Device architecture
Architecturally, the DIO-403 is divided into a non-isolated logic part and an
isolated part with I/O buffers.
Every line is protected from overvoltage and electrostatic discharge by a Harris
SP720 overvoltage & ESD electronic protection array. One 22Ωcurrent limiting
resistor limits current in every line.
I/O lines are neither pulled-up nor pulled-down. Thus, connected equipment
should actively drive these lines high or low. An unconnected or not driven input
line will remain in an arbitrary state.
The layer employs 16,543 buffers with two-by-eight architecture. Thus, the user
can select lines to be input or output with the granularity of eight lines at a time.
1.2 Layer capabilities
The DIO-403 layer is capable of single read/write into the registers as well as
continuous clock reads and writes.
Current firmware supports single read/writes only.

1.3 Layer connectors and wiring
Wiring of DIO-403 is very simple. The user should wire input and output lines
relative to DGND.
TRIGx line is an input for external trigger.

2 Programming using the UeiDaq Framework
This section describes how to program the PowerDNA DIO-403 using the
UeiDaq’s framework API.
The 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.
The following section will focus on the C++ API but the concept stay the same no
matter what programming language you use.
Please refer to the “UeiDaq Framework User Manual” to get more information on
using other programming languages.
2.1 Creating a session
The Session object controls all operations on your PowerDNA device. Therefore,
the first task is to create a session object:
CUeiSession session;
2.2 Configuring the resource string
The 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, the device class is pdna.
For example, the following resource string selects digital input channels 0,1,2,3
on device 1 at IP address 192.168.100.2: "pdna://192.168.100.2/Dev1/Di0:3"
session.CreateDIChannel("pdna://192.168.100.2/Dev1/Di0:3");
2.3 Configuring the timing
You can configure the DIO-403 to run in simple mode (point by point) or
buffered mode (ACB mode).
In simple mode, the delay between samples is determined by software on the host
computer.
In buffered mode, the delay between samples is determined by the DIO-403 on-
board clock.
