1 Introduction
1.1 Using this Manual
This manual is designed to assist in installing, operating, and maintaining Honeywell
Model WBR-AK Base Radios. The manual is broken into sections as follows:
2 Quick Start
This section summarizes what must be done in order to get the device installed,
configured, and in operation quickly. However, it does not provide detailed or how-to
information to perform the tasks outlined.
3 Installation
This section explains mechanical installation and correct wiring for power and
communications. Also covered in this section are instructions for “daisy-chaining” multiple
Base Radios together on the same power and communications supplies. Proper
termination of the communications is also covered.
4 General Configuration
In this section the general configuration options such as password protecting, and
selecting a user password are discussed. Also covered is the importance of the Number
of Wireless Instruments (HI RFID) setting, as well as the configuring of this setting.
5 Configuring the RF Communications
This section covers the setup of the Base Radio RF Communications that allow the Base
Radio to communicate with Transmitters that have been placed in service.
6 Configuring the MODBUS Communications
This section covers the various Base Radio settings that must be configured for Modbus
communication such as baud rate, parity, device ID’s, and register mapping modes. Also
covered in this section is a brief discussion of the Modbus communications protocol and
Modbus commands that are used with this device.
Modbus register locations are also discussed within this section.
7 Technical Specifications
This section explains the technical specifications that are associated with this device,
such as power characteristics, accuracy, and operating characteristics.
1.2 About the Device
The Honeywell Base Radio is a reliable Radio Frequency (RF) transceiver with a variety
of available outputs contained in an explosion proof housing useable in many hazardous
and hard-to-reach areas. The time and expense of running wires often makes it difficult to
measure parameters that have an economic impact on your plant operation, but the Base
Radio allows you to quickly and accurately monitor those devices at a fraction of the cost,
giving you bigger and faster returns on your instrumentation investments.
The Base Radio communicates in a secure, frequency digital protocol over a band of
frequencies from 902 MHz to 928 MHz. These devices do not require permits or licenses
and are easily setup and installed right out of the box.
