Installation
Overview
The Mac-Lab\CardioLab Data Pipe service application has two features: data pipe and waveform
data server. The service application is installed together with the CardioLab application to the
Acquisition system.
The data pipe feature sends waveform data from an Acquisition system to a connected client
computer. The feature consists of the service application that runs on the Acquisition system
and an application that runs on a connected client computer. The client application is provided
as source code that needs to be compiled using Microsoft Visual C++ 2010 Express on the
client computer. The client application sample code receives the waveform data and saves it
to a binary data file.
The waveform data server feature sends waveform data, patient demographics, channel
configuration, and other information to a client, when requested. The feature consists of the
service application that runs on the Acquisition system and an application that runs on a
connected client computer.
Data Pipe Installation – Client Sample Application
The data pipe sample application source code is provided along with Microsoft Visual C++ 2010
Express solution and project files. Copy the client application folder from the Data Pipe Installation
CD onto the client computer. After downloading Microsoft Visual C++ 2010 Express, the solution
file can be opened. The source code will build without modification.
Uninstall
To uninstall the client components, delete the folders copied to the client system during installation.

2088535-017B EN Mac-Lab/CardioLab Data Pipe Reference Manual 2-1
Developing with the Client Sample Application
Overview
The command line in Microsoft Visual C++ 2010 Express must be set up before the application will
start. This can be done by right-clicking the MLCLDataPipeSampleApp project name and
selecting Properties. Navigate to the Configuration > Debugging page and put the command
line in the Command Arguments text box
The sample application saves waveform data (for the channel indice(s) specified on the command
line) to a binary file. Each data point is saved in a double precision floating point format. The binary
file has the following format and can be read into a signal processing application if desired.
Binary File Format:
[channel0, sample0][channel1, sample0][channel2, sample0] [channel0, sample1][channel1,
sample1][channel2, sample1] [channel0, sample2][channel1, sample2][channel2, sample2]

Command Line Set Up
For the data pipe component of the sample application to work, the following command line
parameters are required.
Developing with the Client Sample Application
-localIP The -localIP command line parameter identifies the IP address of the network adapter to use for sending/receiving data
-channel The -channel command line parameter identifies the channels to save to the binary data file. This parameter can be
between the client and Acquisition system.
listed multiple times on the command line if more than one channel is to be saved. The data pipe sends all channel data
that is actively being saved on the Acquisition system. The value associated with the -channel command line parameter
is the channel index as shown in the study configuration on the Acquisition system.
For the DICOM component of the sample application to work the following command line
parameters must be supplied in addition to the -localIP and -channel parameters.
-acqIP This is optional. If this command line parameter is not present then the data pipe application must be running on the
-clientAETitle The -clientAETitle command line parameter identifies the AE title of the client application for DICOM communications.
-acqAETitle The -acqAETitle command line parameter identifies the AE title of the Acquisition DICOM application. The value for this
-acqDICOMPort The -acqDICOMPort parameter is the port that the Acquisition system’s DICOM application uses for network
Acquisition system with a study open for DICOM functionality to work.
The AE title listed for the ultrasound or x-ray system on the Acquisition system must match the value provided for this
parameter. The ultrasound or x-ray system's AE title can be found by going to the Administration > System Settings
page. On the System Settings page select the 'Connectivity' page and the 'Remote Hosts' tab.
parameter must match the Acquisition system's local AE title. The Acquisition system's local AE title can be found by
going to the Administration > System Settings page. On the System Settings page, select the 'Connectivity' page
and the 'Local Host' tab
communication. The value for this parameter must match the DICOM port listed on the Acquisition system. To find the
DICOM port on the Acquisition system, go to the Administration > System Settings page. On the System Settings
page select the Connectivity page and the Local Hosts tab
Optional Parameters
-outputFile The -outputFile parameter specifies the file to save binary data to on the client system. If this parameter is not supplied,
the data is saved to a file called output.dat in the application’s working directory.
-timeout The -timeout parameter specifies how long (in seconds) the application tries to find the data pipe before reporting an
error. This parameter defaults to 10 seconds. During this time the client application is waiting to receive a broadcast
message from the Acquisition system.
Example command line (data pipe functionality only):
-localIP 192.168.6.6 -channel 1 -channel 2 -channel 6
The command line above will use the client application to save channels 1, 2, and 6.
Example command line (data pipe and DICOM functionality):
-localIP 192.168.6.6 -channel 1 -channel 2 -channel 6 -acqIP 192.168.6.5 -clientAETitle
DataPipeClient -acqAETitle DataPipeAcq -acqDICOMPort 1224
The command line above will use the client application to save channels 1, 2, and 6 as well as
enable the application’s DICOM functionality.

Sample Rates
CardioLab study configurations can be setup for 1K, 2K, or 4K sample rates. The actual sample
rates are:
1K Study: 977Hz
2K Study: 1953Hz
4K Study: 3906Hz
This information is provided for use in signal processing applications.
Study Configuration Notes
When using the data pipe, the ECG signals in the study configuration should have Always Save
turned on.
Changing a study configuration is not supported while connected to the data pipe. Study
configuration changes are not identifiable in the client application. With the sample application, this
will result in an output binary file with data from two different study configurations. The point where
the study configuration changed is not identifiable in the output binary file.
If a study configuration change is needed, close the client application first. Start the client
application again with a new output binary file after the study configuration has been changed.

Network
Set Up
To use the data pipe feature, the Acquisition system and the client application must be on the
same subnet to communicate with each other. The recommended way of doing this is connecting
the Acquisition system and client computer with an Ethernet cable. If a mapping system is not
present, the mapping system Ethernet port can be used. Otherwise, the client system can be
placed at an IP address anywhere on the Local Area Network that shares the same subnet as the
Acquisition system.
1. Select Start > Control Panel > Network and Sharing Center > Change adapter settings.
2. Right-click the network adapter in use and select Properties.
3. Select the Use the following IP address radio button and assign an IP address and subnet
mask.

Acquisition System Client System
IP: 192.168.5.2 (default mapping system address) IP: 192.168.5.6
Subnet: 255.255.255.0 Subnet: 255.255.255.0
Acquisition System Client System
IP: 192.168.0.1 (LAN address assigned by hospital IT) IP: 192.168.0.10 (hospital IT assigned address on same
Subnet: 255.255.255.0 Subnet: 255.255.255.0
4. Open a command prompt on each system and enter ping [other system’s IP] to verify
connectivity.
Troubleshooting
Firewalls may be blocking communications between the two systems. To use the data pipe
feature, the Mac-Lab/CardioLab Data Pipe must be able to send broadcast messages from the
Acquisition system to the client system to begin creating a connection. Make sure that the firewall
is not blocking communications.
The following ports are used for data pipe communication:
Example IP Address / Subnet Mask Pair Using the Local Area Network
LAN subnet)
10300: Broadcast message received on client on this port.
10301: Port that Acquisition system uses for TCP communication.
10304: Port that client system uses for communication with the Acquisition system.
