This section distinguishes between Operator Interfaces and Field Interfaces to the BAS. The Operator Interface refers to the main 'front-end' method for accessing and operating the BAS. The Field Interfaces typically access the BAS from the controller-level and have limited functionality, and may include HID, LDP, and ZBI as described below. This section describes the devices only; OI functionality is generally covered in the Software, while Field Interface functionality is detailed further in the individual Controllers
Operator Interfaces (OI)
Dedicated Operator Workstation (OWS)
Dedicated PC(s) with proprietary workstation software

Additional Information
Includes a listing of available Gateways, Routers and other devices that provide additional communications flexibility into and out of the BAS. Repeaters, bridges, standard modems and the like are typically not included here. Note: If in use by the BAS, the Internet/building IT Network is extremely open and non-proprietary. If a vendor uses the IT Network, CI devices such as IP routers and hubs can be purchased from third parties.
