1 Network Overview This chapter provides an overview of Millennial Net’s Building Automation system.
Network Overview Product Overview The Building Automation system uses Millennial Net's i-Bean® technology to allow monitoring and configuring of building thermostats over a wireless network. When installed, the i-Bean wireless network replaces the RS-485 bus typically used between the controller and the associated thermostats, eliminating the need for running cables between devices.
General Network Characteristics • WebGen Controller, model: Web-i • Tridium Controller, model: JACE-403 Gateway Server Millennial Net’s Gateway Server translates messages from the controller’s RS-485 port to Millennial Net packets for wireless transmission to a thermostat’s Sub-base Router and vice versa. The Gateway Server also manages the wireless network. Sub-base Router (mounted to back of thermostats) Millennial Net’s Sub-base Router provides each thermostat with wireless communications.
Network Overview i-Bean Network Overview Millennial Net's innovative, self-organizing i-Bean network technology combines micro-power sensor interface Sub-base Routers and Standalone Routers with a Gateway Server to form a reliable, scalable Star Mesh wireless network (see Figure 1-2). This is a unique solution for low data-rate networks that provides fault-tolerant networking.

2 i-Bean Network Hardware This chapter provides information on the parts associated with each i-Bean device and lists the technical specifications of each device. Also included here is a section containing recommendations for attaining optimal network performance.
i-Bean Network Hardware Gateway Server Shown in Figure 2-1, Millennial Net’s Gateway Server (model GS-5209Z1) translates messages from a controller’s RS-485 port to Millennial Net packets for wireless transmission to thermostats, and vice versa. Figure 2-1. Gateway Server and associated parts 1 2 4 3 Gateway Server Parts Referring to Figure 2-1, the Gateway Server assembly is shipped with the following items: 1. Gateway Server 2. Gateway Server antenna 3. RS-485 cable (DB-9 to tinned leads) 4.
Gateway Server Gateway Server Specifications Components • • • RS-485 Network Port: – DB-9 (female) – Configured internally to 9600, 8, n, 1, no flow control Power: – Jack for 12 VDC from external regulated AC adapter (included); OD 5.5 mm, ID 2.5 mm; outer connector is ground, inner is +12 V. – Slide switch turns device off and on READY LED: Illuminates solid after the device initializes (approx.
i-Bean Network Hardware Sub-base Router Shown in Figure 2-2, Millennial Net’s Sub-base Router (model RT-5209Z1) provides the following functionality: • Provides wireless communications for thermostats via unobtrusive add-on. • Converts thermostat data on RS-485 line to/from wireless, transceiving in license-free 916 MHz ISM band. • Fits between Basys model SZ1022 thermostat and wall. • Accommodates mounting to wall or junction box. • Passes wiring through the Sub-base Router to the thermostat.
Sub-base Router Sub-base Router Parts Referring to Figure 2-2, the Sub-base Router is shipped with the following: 1. Sub-base Router 2. Screws (not shown) for mounting the Sub-base Router to the thermostat. Note: For instructions on installing the Sub-base Router, refer to the Quick Start Guide for Building Automation (P/N DOC-0010). Sub-base Router Specifications Components • RS-485: Screw terminal strip for RS-485 + and RS-485 - connections.
i-Bean Network Hardware Standalone Router Shown in Figure 2-3, Millennial Net’s Standalone Router (model RT-5209Z2) provides the following functionality: • Used as repeaters to: • – Extend the range between a Sub-base Router and the Gateway Server or between Sub-base Routers. – Circumvent communication path obstacles. May be mounted wherever needed and where 120 VAC power is available. Figure 2-3.
Standalone Router Power Requirements 120 VAC, using attached plug-in regulated AC adapter Dimensions • Height: 3.7” (95 mm) plus 2.9” (74 mm) antenna height • Width: 3.4” (87 mm), including mounting flanges • Depth: 1.
i-Bean Network Hardware Performance Considerations Since the i-Bean wireless network uses radio waves to communicate between devices, there are a number of items that need to be considered when implementing this type of network. This section of the manual provides a number of suggestions that will ensure that your wireless network will operate at its peak level of performance. Warning These electronic products are sensitive to electrostatic discharge (ESD).
