List of Tables Notes: xiv UtiliNet Technical Reference Guide
Chapter 1 Introduction This manual provides technical information for the line of radios used in the UtiliNet® Wireless System. Included are photos, specifications, diagrams, and accessories for each radio type as well as detailed information on applications using the radios and other related information.
Introduction UtiliNet Basics UtiliNet is a wireless data communications network based on spread-spectrum radio technologies. Network of Intelligent Radios UtiliNet radios form the foundation of a UtiliNet network and serve multiple functions. • Each radio can communicate to end devices for some data collection or control function.
Introduction Mesh Architecture Much like a giant net over a service area—UtiliNet radios work together to create a mesh. At each point where one thread of the net crosses over another, a node is created in the wider area network. A node could be represented by one radio attached to end-devices. Because each radio can forward messages to and respond to every other radio in the network, each radio is an equal participant in the network.
Introduction About This Manual This technical reference guide explains UtiliNet in great detail from application design through implementation and operation to after-sales services and support. Also included are a glossary of important terms and papers on extended UtiliNet topics. Chapter 1-4 Title Description 1 Introduction Provides introductory information about the Utilinet network and this manual. 2 Integrated WanGate Radio (IWR) Describes the Integrated WanGate Radio.
Introduction Icons Throughout the document, various icons are used to draw your attention to important information. Below are examples: The warning icon identifies information that is critical to maintaining the integrity of the software or data. The caution icon identifies important information. The note icon identifies information that clarifies a point within the text. Contacting Technical Support Within the United States, Cellnet technical support is available Monday through Friday, 8:00 A.M.

Chapter 2 Integrated WanGate Radio (IWR) The UtiliNet Integrated WanGate Radio (IWR) communicates via RS-232 to end devices and is designed for internal mounting, such as inside a remote terminal unit enclosure. The radio is commonly interfaced with such devices as remote terminal units (RTUs), programmable logic controllers (PLCs), and other intelligent end devices (IEDs). The Integrated WanGate has two RS-232 serial ports—a LAN Packet Protocol Port and a Transparent Port.
Integrated WanGate Radio (IWR) The radio comes with a standard N-Female antenna connector mount and mounting hardware (see Figure 2.2). Included are the following: • Integrated WanGate Radio • Two mounting brackets • Four 6-32 screws • Four 10-32 screws • Four 10-32 hex nuts • DC power connector with 48" cable • Reference mounting drawing Figure 2.2 Integrated WanGate Radio DC Version Components 120 VAC to 12 VDC Power Adapter (P/N 105690-000) This Power Adaptor Cube (see Figure 2.

Integrated WanGate Radio (IWR) Figure 2.9 Antenna Kit Components Filter (P/N 106460-000) This band-pass filter (see Figure 2.10) attenuates out-of-band signals and is used to reject interference from sources such as paging and cellular phones. It is designed to be used with the IWR (both DC and AC) and to be placed inside an RTU or like enclosure. It is a passive filter and connects in-line with the antenna coaxial cable. The coaxial cable on the filter is RG-223 and is 35" long.
