Symptom
If an NGP panel communicates with a Communication Server running on a computer with a single-core processor, that NGP panel might not come online.
This might occur if the computer is either a physical machine with a single-core processor, or a virtual machine with a single processor core assigned to it.
Resolution
To work around this issue, add the following line to the ACS.INI file on the computer running the Communication Server, under the
[CommunicationServer]
section:ComPortThreadLoopDelay=5
Save and close the ACS.INI file, then restart the LS Communication Server service.
Applies To
NGP
Additional Information
Note that computers with multiple-core processors are not affected by this issue.
