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...
Page 9 - Compatibility
The Honeywell Base Radio may be used to communicate with many Transmitters in various applications. You can use this device for long-term monitoring in remote locations, for short-term data gathering on process conditions, or to quickly test the economic viability of a new installation. The purpose ...

Once you have located these terminal blocks you can wire the Base Radio accordingly. The best way to wire the Base Radio is to: Remove both terminal blocks from the jacks on the Base Radio • • • • Insert the wire through the conduit hole on the bottom right of the Base Radio Secure the wire into the...

software may require the use of an RS-485 to RS-232 converter, as most PCs cannot be wired directly to RS-485. To wire the RS-485 cable to the Base Radio we recommend using a 22AWG twisted pair shielded wire. Place one of the twisted pair wires in the “A” (Tx+/Rx+) slot of the same terminal block as...
Page 20 - Figure 3-7 Daisy-Chaining Power to Multiple Base Radios
3.2.6.1 Daisy-Chaining Power to Multiple Base Radios A consideration when daisy-chaining power to multiple Base Radios is the power draw at power supply. Each Base Radio will typically draw 200mA @ 24VDC. This means a single Base Radio will draw a typical average power of 4.2W. If using the supplied...

Page 22 - Figure 3-10 Example of Correct Termination Resistor Setup
(recommended in section 3.2.1) the value of the resistor should be a 120 Ohm ¼ watt resistor. To terminate a Base Radio, place one end of the resistor in the open terminal block’s B slot and place the other end of the resistor in the open terminal block’s A slot. Doing so will place the resistor acr...
