A daemon (pronounced DEE-muhn) is a program that runs continuously and exists for the purpose of handling periodic service requests that a computer system expects to receive. The daemon program forwards the requests to other programs (or processes) as appropriate. Reference: https://whatis.techtarget.com/definition/daemon

A computer daemon is a constantly running program that triggers actions when it receives certain input. For example, a printer daemon spools information to a printer when a user decides to print a document. A daemon running on a mail server routes incoming mail to the appropriate mailboxes. Web servers use an "HTTPD" daemon that sends data to users when they access Web pages. Reference: https://techterms.com/definition/daemon

• Then, press enter through the remaining demonsdaemons.
• Select 2 again and you should see the following:

• Select R to restart the selected demondaemon.
• Press enter through the remaining demons daemons again and the demons daemons should be running.

Examples of various types of programs and interfaces

Try communicating with the piece of equipment again. If it still fails, check the cabling and connectors.

Cabling

• Ensure that the connector is securely snapped to the port on the Rocket or Digi Port.
• Ensure that the connector is securely snapped to the connector on the equipment.
• Make sure that no rust has developed on any of the connectors.

Connectors

• Refer to and follow the instructions on the Machine Interface Setup document for proper connectors and configurations for all equipment.
• If there are still problems communicating, open an Optifacts support ticket for proper escalation.
