Page 7: Section 1: Introduction
Introduction 1.1: USING THIS MANUAL This manual is designed to assist in installing, operating, and maintaining Accutech Model WI-BR-I-XP, WI-BR-I-XP-MOD and WI-BR-I-XP-AO Base Radios. The manual is broken into sections as follows: Section 2: In a Hurry? This section summarizes what must be done in order to get the device in- stalled, configured and in operation quickly. -
Page 8: About The Device
902MHz to 928MHz. These devices require no wires, permits or licenses, and are easily setup and installed right out of the box. The Accutech Base Radio may be used to communicate with many Field Units in various applications. You can use this device for long-term moni- toring in remote locations, for short-term data gathering on process condi- tions, or to quickly test the economic viability of a new installation. -
Page 9: Section 2: In A Hurry
Base Radio (WI-BR-I-XP-MOD only) (See Diagram below) Place terminating resistor in terminal only if Base Radio will be used as an End Unit (See side Diagram) Wire the Analog Output Loop (WI-BR-I-XP-AO only) (See Diagram) Caution If the Base Radio is not energized for more than 30 minutes, the Field Units should also be turned off to preserve battery life. -

Page 19: 3: Modbus Parity
Section 6: Configuring the Modbus Communications The Modbus Parity distinguishes which type of parity is used to validate 6.1.3: Modbus Parity Setting each packet of information on the RS-485 Network. The type of parity required is usually indicated by the user’s PLC. Selecting EVEN or ODD parity will automatically include one STOP bit per frame. -
Page 20: Modbus Communication Protocol
Accutech Wireless Base Radio User Manual The Base Radio connects to the Host (Master) system using Modbus over 6.2: Modbus Communication a serial RS-485 line. The Base Radio supports Modbus RTU transmission Protocol mode at baud rates of 9600, 19200, 38400, 57600, or 115200 baud with even, odd, or no parity and 8 data bits. -
