Aurora Interface and Diagnostics (AID) Tool
The Aurora Interface and Diagnostics (AID) Tool is a device
that is a member of the Aurora network. The AID Tool
is used to troubleshoot
equipment which uses the
Aurora control via Modbus
RTU communication.
The AID Tool provides
diagnostics, fault
management, ECM setup,
and system configuration
capabilities to the Aurora
family of controls. An AID
Tool is recommended,
although not required. The AID Tool simply plugs into the
exterior of the cabinet in the AID Tool port.
