Zone Support
MeterLink® is the component of OneTouch® DataLink® that establishes a connection
between a meter and the OneTouch® DataLink® Data Management System. Each MeterLink® instance allows up to 500 connections, both client connections (serial clients, OneTouch® DataLink® Wireless Units) and server connections (OneTouch® DataLink® Sync, serial servers, and terminal servers). Server connections are limited to 200, as they are always open and thus use more resources. To use more connections you must create another instance of
MeterLink®.
SureStep® meters synchronize their clocks with the MeterLink® that they communicate with. In order to support multiple time zones, a MeterLink® instance must be created on a
different computer for each time zone. The following configurations are possible: • Multiple MeterLink® Instances on a Server.
• MeterLink® on Multiple Servers for Multiple Time Zone Support.

Verify System Requirements
Verify that the intended computer(s) meet the system requirements for OneTouch®
DataLink® Web, which are the same requirements as those for Windows Server 2003/2003 R2/2008/2008 R2.
Verify Installed Components
First install OneTouch® DataLink® Web on the host computer. See Chapter 2 and Chapter 3, as appropriate for specific installation instructions.
STEP 1.
Creating a Replicated Connectivity Account
The OneTouch® DataLink® Web connectivity account is a single user allowing a Terminal Services Remote Desktop connection to the OneTouch® DataLink® Data Management System. A user (eg, a point-of-care coordinator) uses this account to start up and shut down the OneTouch® DataLink® Data Management System and to manage meter connectivity. Normally with OneTouch® DataLink® Web, only one connectivity account is created to run and manage MeterLink®. To exceed the current connection limitations of MeterLink® you must create multiple instances of it. Each instance of MeterLink® runs in its own unique connectivity account. You can then remotely log on to different connectivity accounts as needed to centrally manage the different instances.
1. Log on as an Administrator and, using Terminal Services, ensure that all OneTouch® DataLink® Web remote users are logged off. Shut down all OneTouch® DataLink® components (MeterLink, Results Processing, Activity and Error Logging) if they are running.
2. Use the Control Panel’s Regional and Language Options dialog box to examine the number and date preferences; change them as needed for the Connectivity Account. Make sure the clock is set correctly and the correct time zone is chosen.
3. To create a replicated connectivity account, click Start, and then point to Administrative Tools > Computer Management.
4. In the left pane of the Computer Management applet, expand System Tools and then Local Users and Groups. Click Users. A list of users appears in the right pane.
For a domain account use Administrative Tools > Active Directory Users and Computers on the domain controller to get to Users rather than the Local Users and Groups.
5. Right-click Users, then select New User in the pop-up menu.
6. In the New User dialog box, enter the user name, full name, description, and password, and then confirm the password. The user name may be any appropriate unique name (the instructions that follow assume DataLinkConnect2 is the user name entered). For the full name and description, DataLink Web Connectivity 2 and DataLink Web
Connectivity Services 2, respectively, are recommended. Enter a password and select the options required by your organization. Click Create to create the user. To return to the Computer Management applet, click Close.
7. In the pane which lists the users, right-click the user just created, then click Properties. 8. In the Properties dialog, click the Member Of tab, then click Add.
9. In the Select Groups dialog, click Advanced. 10. In the dialog that appears, click Find Now.
12. In the Select Groups dialog that appears, click OK. You are returned to Member Of, which now lists the Remote Desktop Users group. If other groups are also listed, select and remove them as needed.
13. Click Apply to make the user part of the Remote Desktop Users group. If your organization requires further user account property modifications, apply them here. 14. Click the Sessions tab, and then set all options to Never. Also, select the Disconnect
from session and from any client options. Click Apply. To close the Properties applet, click OK. Close Computer Management.
15. Create the Connectivity Account’s user profile by logging onto the Application Server as the Connectivity Account user.
16. Log off and then log on again as an administrator.
STEP 2.
Create Another Instance of MeterLink®
You do not have to re-install OneTouch® DataLink® Data Management System to create another instance of MeterLink®; a copy of the existing MeterLink® installation can be made. 1. Navigate to the OneTouch® DataLink® installation folder where MeterLink® is installed.
The default folder is C:\Program Files\LifeScan\MeterLink. 2. Right-click MtrLink.exe and select Copy.
3. Navigate to the LifeScan folder (the default folder is C:\Program Files\LifeScan), right- click and select New > Folder. Give the folder a unique name (eg, MeterLink2).
4. Navigate to the new folder (eg, C:\Program Files\LifeScan\MeterLink2). 5. Right-click and select Paste to make a copy of MtrLink.exe.
6. To begin creating a new MTRLINK.INI file, double-click on MtrLink.exe. Double-click on the MeterLink® icon in the system notification area of the taskbar and log on by selecting File > Administrator Access (password is surelink).
7. Add a temporary serial client connection. From the Connections menu, select Add Network Device Connection. For Device Type select Serial Server. Enter any values for the other fields (all fields require an entry). Click OK.
8. Shut down MeterLink®, select File > Exit. When prompted about closing, click Yes. This will create the MTRLINK.INI file.
9. To change the MeterLink® port selection, navigate to the folder with the new copy of MeterLink® (eg, C:\Program Files\LifeScan\MeterLink2) and open the MTRLINK.INI file with Notepad.
10. Scroll down and find the [SocketClientServerInfo] section. Change the Port value from 3001 to another number, eg, 3002. Increase this value for every new instance of MeterLink®, ie, 3001, 3002, 3003 etc.
11. Save and close the MTRLINK.INI file.
NOTE: The SocketClientServerInfo Port number is what MeterLink® uses for client connections; you are configuring it to be different for each MeterLink® instance. This new port number must be used when you configure a serial client or a OneTouch® DataLink® Wireless Unit to communicate with this new MeterLink® instance. Existing devices must also be reconfigured to match the port number of the MeterLink® instance they are intended to communicate with.
12. Double-click on MtrLink.exe. Double-click on the MeterLink® icon in the system notification area of the taskbar and log on by selecting File > Administrator Access (password is surelink).
13. To remove the temporary serial client connection, from the Connections menu, select
Remove Connection.
14. Shut down MeterLink®, select File > Exit. When prompted about closing, click Yes.
STEP 3.
Configure the Instance of MeterLink®
To ensure MeterLink® will start automatically for the new connectivity account, navigate to the new instance’s folder (eg, C:\Program Files\LifeScan\MeterLink2).
1. Right-click on MtrLink.exe and select Create Shortcut. 2. Right-click on the newly created shortcut and select Cut.
3. Navigate to the Startup folder of the newly created connectivity account. If you are using Windows Server 2003/2003 R2, the folder is:
C:\Documents and Settings\DataLinkConnect2\Start Menu\Programs\Startup If you are using Windows Server 2008/2008 R2, the folder is:
C:\Users\DataLinkConnect2\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup 4. Right-click and select Paste.
When you are done creating new MeterLink® instances, use the OneTouch® DataLink® Web logon page and log on to the new connectivity account to start the new instance of
MeterLink®. Consult the OneTouch® DataLink® Connection Guide to add connections. When you are done creating new MeterLink® instances, you can restart the other connectivity accounts by similarly logging in.
