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
PC with CyberStation Software
"Thin" Client Browser Netscape/Internet Explorer/Mozilla - Requires Web.client server software running on a PC on the IT network
"Thick" Client Browser Limelight Software for PC
Product Application(s): N.A.
Handheld Interface Devices (HID)
PDA-Based
Proprietary
Local Display Panel (LDP) Optional enclosure mounted display 4 line x 16 character display (w/19 button input, or 2 line x 16 character display, or 8 line x 3 character display, or 8 LED bar display, and/or Voice module - 50 custom messages (3.5 minutes total)
Zone Based Interfaces (ZBI)
Thermostat with communication port to access local controller/network
Other thermostat types available (without communication ports)
Interface to BAS Networks Primary network ues IP protocol and is compatible with IT network/ Internet
Compatible with the building's IT network? Yes
Protocol(s) BACnet, Proprietary over EIA 485
Cabling and Speeds EIA-485 19.2 kbps 10 BaseT
Expansion Capability Information not provided
Additional Information
Peer-to-Peer or Polling? Peer-to-peer
Protocol(s) Infinet over EIA-485
Cabling and Speeds EIA-485 19.2 k baud
Expansion Capability Information not provided
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.
Model (Device) Application
Model (Device) Net Controller
Application The NetController is designed for integrated communication between Infinet and Continuum controllers. The NetController has 4 EIA-485/EIA-232 serial ports for Infinet, modems, printers, 10 BaseT and 10 Base FL (fiber)and third party devices.
