Connecting 2-wire Equipment

When connecting 2-wire equipment the following functions should be taken into consideration:

  • Auto-null

Every time equipment is changed on a 2-wire port you should auto-null.

  • Enable/Disable the partyline power
  • Line Termination.

These functions can be found in the 2-wire port settings page of the CCM. Navigate to Device > Ports on any unit in the Link-Group.
