Overview
Introduction
The intent of this document is to describe the usage and integration of best practices for
the CDIS-NCE connectivity software.
The Welch Allyn CDIS-NCE software is intended to provide bi-directional connectivity
between Welch Allyn medical devices and various Welch Allyn and non-Welch Allyn data
management systems.
The CDIS-NCE software supports the device initiated network workflow where the device
is sending data to a server. The device initiated network workflow occurs when the device
initiates communication with the server (for example verifying a patient ID, clinician ID, or
sending vitals or ECG data).
The CDIS-NCE software does not honor requests for data from the server.
Intended audience
The intended audiences of this document include:
•
Customer site IT professionals
•
Integrators (integrators or EMR developers)
•
Welch Allyn Field Engineers
•
Welch Allyn Technical Support personnel
Personnel providing integration of devices into EMR systems will need to know the
components included in the software solution (e.g. DCP, NCE, CPSAPI, FileImporter):
•
Site IT professionals will need to understand the TCP/IP Ports used in the
solution.
•
Site IT professionals may need to know basic troubleshooting.
•
Welch Allyn service personnel will need to know basic and advanced
troubleshooting.

Scalability - Vitals
Depending on network performance, a given installation may be able to handle up to 400
devices on a single instance of CDIS-NCE. When the installation requires more devices to
be connected (or the solution is not performing as needed due to network bandwidth,
network, or server performance) it is a best practice to scale up the solution by using load
balance software or hardware between the devices and the CDIS-NCE servers.

Site Maintenance Activities
The following actions may be needed to maintain the system.
NCE Server address changed
The NCE Server address change can happen for a few reasons:
•
Moving from a test environment to a production environment. The facility may have
NCE on a test server and the facility does not want to use that same server for
production.
•
The failure of a server and the resulting need to put in place a new server with a new
IP address.
•
Server software has been split across multiple servers.
To change the NCE Server address:
•
Reconfigure the DCP ordinal settings to point to the correct server(s).
•
The DCP settings are stored in the registry at:
“+.(<B/2&$/B0$&+,1(?6<67(0?&XUUHQW&RQWURO6HW?6HUYLFHV?'&3?3DUDPHWHUV”.
The configuration of DCP is set at install time, however if configuration setting
changes are needed, they can be done through the computer’s Registry.
Note The DCP Windows service (only the Windows service, not server) requires a
restart after any configuration change.
EMR Server address changed
The EMR Server address change can happen for a few reasons:
•
Moving from a test environment to a production environment, where the NCE
configuration needs to be updated to point to the EMR’s production server.
•
EMR server failure and the resulting need to put in place a new server with a new IP
address.
•
EMR server software has been split across multiple servers.
To change the EMR Server address:
1. Open the NCE Configuration Interface. See the
icon in the system tray.
2. Select “Information Network” in the Settings menu on the left column.
12
Site Maintenance Activities

For an ORU Outbound Configuration:
a.
Select Host Index representing the ORU outbound data.
b. Update the Host Address to the proper IP address.
c.
Press the “Save Settings” button on the bottom right of the configuration
interface.
4. Close the NCE configuration interface.
13
Troubleshooting
This section describes issue that could potentially cause a failure condition and steps to
diagnose the issue. Some of the topics have a drawing containing a red indication of the
interface or component that may be at fault.
Device cannot access the network
1. Ensure that the device is within range of an access point.
2. Verify the wireless settings match the network settings:
a.
SSID
b. Radio band
c.
Authentication
d. Passphrase (if needed)
e. Security protocol
3. If you are still having trouble connecting the device to a wireless network, try
connecting the device via Ethernet to determine whether the wireless network is the
issue.

Vitals sent but date-time stamp is wrong
1. Check device’s configuration:
a.
Ensure that the device’s “Time zone” is set to the correct time zone.
b. Ensure that “Emulate Spot Vital Signs LXi” is disabled.
2. Check Server’s configuration:
Ensure that the server’s time zone setting is the time zone corresponding to the
time zone of the devices connected to this server.
Collecting log files and saved or failed files
Log files can be found in the folder &?3URJUDP)LOHV[?:HOFK$OO\Q?1&(. There may
be up to two log files named 1&('HEXJ/RJW[W and 1&('HEXJ/RJW[W. These files are
critical to determine the root causes of issues. Both of these files will need to be
collected when issues arise.
If enabled, a history of the transactions can be found in the SavedCopies folder within the
path &?3URJUDP)LOHV[?:HOFK$OO\Q?1&(. When this feature is enabled in the NCE

Troubleshooting
Welch Allyn Connex® Device Integration Suite (CDIS) Network Connectivity Engine (NCE) software
Configuration, it will save data coming in from the device (DeviceToNCE); messages going
to the host (NCEToHost) containing the exact message that NCE sent to the host; and
responses received from the host (HostToNCE) containing the exact message the host
sent back to the NCE engine. This data is very helpful to diagnose formatting or other
application issues.
If enabled, any failed transactions can be found in the FailedCopies folder within the path
&?3URJUDP)LOHV[?:HOFK$OO\Q?1&(. When this feature is enabled in the NCE
Configuration, it will save data coming in from the device when a failure happens. This is
helpful to see what data was sent from the device that may have caused a failure to
happen.
Limitations
1. CDIS-NCE cannot push a file to a remote server.
If file output is desired, the files must be stored locally on the server NCE is running
within the NCE folder.
2. CDIS-NCE is supported only on Windows OS platforms.
3. Thin client (Citrix or RDP) is not supported. The CDIS-NCE solution is intended to be a
server software solution where the device(s) will connect to CDIS-NCE via a network
connection.
4. CDIS-NCE does not support a Bluetooth connection.
5. CDIS-NCE does not support ADT. CDIS-NCE only supports query-response of patient
or clinician information.
6. Sending of data (e.g. HL7 ORU) is initiated by the device only. A host system cannot
query for data from the CDIS-NCE software or directly from the device.
7. Batch workflow is not a preferred workflow since not all EMR systems can properly
handle sending a bulk set of data.
8. When a test send fails, the test data is saved on the device. The device will attempt to
resend the test data from a failed send when the device sends another (new) test. If
there is something wrong with the test data (as opposed to a wireless connectivity
issue) that caused it to fail a send on the first attempt, it will also fail on the second
attempt. To avoid an abundance of errors in the EMR, remove records from the device
that failed to send.
9. Modifications of the solution configuration (transforms or EMR data mapping) need to
be done by Welch Allyn personnel.
