Configuring Mirth Channels

Depending on the configuration you set up, you will need either four or two Mirth channels.

For a high-availability environment, Vocera recommends the following configuration:

In this configuration, two CWE servers are behind a load balancer, and Mirth Connect is installed on each of these servers. For each copy of Mirth, you must create the following channels:

These channels are provided with the installation package for CWE. On each copy of Mirth, follow the instructions in Importing an Existing Channel to import the channels, and then configure the channels as follows:

  1. In the HL7Receiver_Parser channel, click the Source tab. In the Listener Port field, type the port that the patient gateway is using. If you are connecting to a Philips system, in the Send ACK radio button list, select No.
  2. In the JSONCreator channel, click the Destinations tab. In the Host Address field, type the IP address of the load balancer. Set Keep Connection Open to Yes if you want to maintain a persistent connection to the JsonReceiver channel (Vocera does not recommend this).
  3. In the JsonReceiver channel, click the Destinations tab. The path specified in the Directory field is set to C:/Vocera/mVisum Alerts/MVisum Message Generator/HL7 by default. If you have installed CWE in a folder other than C:/Vocera, update the Directory field accordingly.
  4. In the Monitor channel, click the Destinations tab. The path specified in the Directory field is set to C:/Vocera/mVisum Alerts by default. If you have installed CWE in a folder other than C:/Vocera, update the Directory field accordingly.

For an environment that is not high availability, Vocera recommends installing Mirth on the server on which you have installed CWE:

On this Mirth server, you must create two channels:

Import these channels from the installation package for CWE, and then follow these instructions to configure them:

  1. In the HL7Receiver_Parser channel, click the Source tab. In the Listener Port field, type the port that the patient gateway is using. If you are connecting to a Philips system, in the Send ACK radio button list, select No.
  2. In the JSONCreator channel, click the Destinations tab and make the following changes:
    • Make a copy of the contents of the Template field.
    • In the Connector Type field, select File Writer.
    • In the Directory field, type <installdir>/mVisum Alerts/MVisum Message Generator/HL7. Replace <installdir> with the folder in which you have installed CWE (the default is C:/Vocera).
    • In the File Name field, type ${UUID}.json - this ensures that the output is a JSON file.
    • In the Template field, paste the text that you copied earlier.

After you have configured your Mirth channels, you can add additional alarm reasons or alarm levels if needed. See Configuring a New Alarm Reason and Configuring a New Alarm Level for more information.
