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.

Overview

Performance guidelines
This section describes a few topics to consider when setting up the connected solution
(e.g. NCE software specifications, type of server hardware, number of virtual machines,
number of devices connected per virtual machine, etc.). Please consider the following
when configuring the system as it will have some impact on performance based on the
type and number of devices used in the environment.
For applications that are made up of only episodic devices (e.g. spot check), one CDISNCE server can be used for up to the specified number of devices per the technical
specifications.
For applications that combine episodic and continuous devices, the following actions are
recommended:
1. The technical specifications are followed for deterministic performance and high data
reliability.
2. The NCE software is connected to a host capable of receiving and processing
concurrent messages on the same IP/port.
3. Configure the NCE’s continuous host index’s maximum concurrent connections
setting as equal to the number of continuous devices connected to the instance of
NCE.
4. Configure the HL7 integration engine to have one connection per continuous device
plus one additional connection for every 10 episodic devices.
For example:
a.
If the environment has 250 devices connected to the same IP/Port of the HL7
integration engine and 30 are continuous and 220 episodic, then NCE’s
continuous host index’s max concurrent connections and the HL7 integration
engine’s max connections should both be set to 52 = (30 + 220 / 10).
b. If the environment has 42 devices and all 42 devices can work as continuous
monitors, then the configuration must be set for the worst case. NCE’s
continuous host index’s max concurrent connections and the HL7 integration
engine’s max connections should both be set to 42.
5. If the environment has 288 devices and all may be used as a continuous device,
based on the technical specifications, six NCE servers are required to support the six sets
of 48 continuous devices. Virtual servers can be used, however each virtual server needs
to meet the technical specifications, so the server hardware needs to scale to support all
six virtual images.

Scalability - Vitals
Depending on network performance, a given installation may be able to handle up to the
specified number of 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:
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Welch Allyn
DCP\Parameters”
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 Welch Allyn 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.
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.
3. Close the NCE configuration interface.

Collecting log files and saved or failed files
Log files can be found in the folder &?3URJUDP)LOHV[?:HOFK$OO\Q?1&(. There may
be many log files named 1&('HEXJ/RJ*W[W. These files are critical to determine the root
causes of issues. These files will need to be collected when issues arise.
If enabled, a history of the transactions can be found in the SavedCopies folder within the
path &?3URJUDP)LOHV[?:HOFK$OO\Q?1&(. When this feature is enabled in the NCE
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.

Advanced troubleshooting
Please use this section to try to answer a few service related questions.
Note
To fully debug:
•
Log level must be set to 9 prior to the occurrence of the fault, and
•
SavedCopies files is enabled and set to at least 7 days and at least 1000 files.
Problem
I can’t download a patient list to the
device
Solution
The reason for failed transactions can be identified by
using the NCE log files and the saved transaction files.
I scanned a patient ID but the device is Note: Default log file location: C:\Program Files
not showing the patient’s demographics. (x86)\Welch Allyn\NCE
I took vitals but it failed to send.
1. Select the log file containing data around the time of
the failure
2. In Notepad++ enter “Response Type = NACK” into
the Find dialog
3. Press “Find All in Current Document”. This will
display all the failures in this log file
4. Note the MessageContext number next to the line
containing “Response Type = NACK”
Look in the file and find where the log file shows
“Attempting to transform XML data using provided .xsl
sheet” and matches the same MessageContext
number.
If the next line shows “Connecting to information host”
and matches the same MessageContext number then
this NACK was a failure from a message sent to the host
system (e.g. EMR).

5. Around this area in the log there will be 3 lines that
say “XML formatted device data saved locally to
file”. These lines point to the saved transaction
files:
a.
DeviceToNCE.xml
Data sent from device to NCE in the WACP

Patient List: Contains data that the device sent
for the query; e.g. org; location
Patient ID: Contains data that the device sent
for the query; e.g. patient ID

data
b. NCEToHost.txt
Data sent from NCE to host in the host format
(e.g. HL7)
Patient List: Contains data that is sent to the
host for the query; e.g. org; location
Patient ID: Contains data that is sent to the
host for the query; e.g. patient ID
Vitals Send: Contains patient data; clinical data

How can I tell the % of successful
messages and the % of failed
messages?
21
Searching data within the NCE log file can help
determine the quality and reliability of the
communications.
1. Select the log file containing data around the time
statistics would like to be captured. Typically the
latest log file is sufficient.
2. Find the number of messages sent to all hosts
(Patient List, ClinicianID query, Vitals, etc.)
a.
In Notepad++ enter “Connecting to information
host” into the Find dialog
b. Press “Find All in Current Document”. The
number reported at the bottom of the display is
how many messages were sent from NCE to all
hosts.
3. Find number of successful responses from all hosts
a.
In Notepad++ put “ACK received from external
host” into the Find dialog
b. Press “Find All in Current Document”. The
number reported at the bottom of the display is
how many successful responses were returned.
4. Find number of unsuccessful responses from all
hosts
a.
In Notepad++ put “Response Type = NACK”
into the Find dialog
b. Press “Find All in Current Document”. The
number reported at the bottom of the display is
how many unsuccessful responses were
returned.
Successful % = “ACK received from external host” /
“Connecting to information host” * 100
Failure % = “Response Type = NACK” / “Connecting to
information host” * 100
NOTE: It is possible that Successful % + Failure % do
not add up to 100% exactly because #5 is a measure of
message success at the transmission level, while #6
could be a transmission or an application error. However
these measures can give an indication for how
successful the interface is during the time represented
by the log file.

That statement does not clarify if the failures are
network-related or if the failures are data-related. If
timeouts occur between NCE and one or more hosts,
the host was not available when the problem occurred
at the device.
1. Select the log file containing data around the time

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.
