Installation Using a Physical Serial Port

If your server has two physical serial ports, we recommend that you connect the PMS system to COM Port 2. For systems with only one physical serial port, it is necessary to reprogram COM Port 1 from its default assignment for the NuPoint UM PPP service (an external dial-up modem service).  

Notes:

To connect the PMS to a physical serial port  on the single-node NuPoint UM system:

  1. Connect a null modem serial cable between the PMS COM Port and a NuPoint UM COM Port.  Make note of which NuPoint UM COM port you use.

  2. Log in to the Web Console.

  3. From the navigation tree, click Offline Configuration > Edit Offline Configuration. The Offline Configuration navigation tree opens.

  4. When prompted to Duplicate Active Configuration, click Yes.

  5. In the navigation tree, click External Applications.

  6. Do one of the following:

  7. To connect to COM1:  

  1. Click Save.

  2. In the navigation tree, select Commit Changes and Exit. Confirm the commit. Your changes are now saved to the duplicate (inactive) configuration. Configuration changes will not take effect until you have activated the inactive configuration.
