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.
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 of this guide is to help you install, configure and maintain your Honeywell Base Radio. 1.3 Unpacking Remove the Packing List and check off the actual equipment received.
2 Quick Start This section summarizes what must be done in order to get the device installed, configured and in operation quickly. Additional detailed information is found throughout this guide. Steps 1-3 refer to the following diagram: Figure 2-1 Overall Wiring Schematic 3 1. Wire 24VDC power to the Base Radio using the power terminals on either the WMT or the Modbus connection. Do not apply power to both sets of terminals. 2. Wire WMT RS-485 communications to the left terminal of the Base Radio.
5. The Base Radio RF settings should be configured as follows: • Set the RF Channel to any available RF CHAN that matches the one used by the Transmitters you wish to communicate with (other than RF OFF). • Set the Baud Rate to 76.8 K or to the Baud Rate used by the Transmitters with which you wish to communicate. • HI RF ID = the highest transmitter RF ID you assign to this network. 6. Configure the Modbus settings 7.
3 Installation This section discusses both the mechanical and electrical aspects of installation. It is divided into the following sections: 3.1: Mechanical Installation 3.2: Electrical Installation 3.1 Mechanical Installation In this section, the mechanical installation instructions are discussed for the various setup capabilities of the Base Radio. The subsections are as follows: 3.1.
Figure 3-1 General Layout Remember, the approximate line of sight range between a Transmitter and Base Radio is determined by the Baud Rate as listed below: • 76.8K -76.8 Kbaud, Range of 500 to 750 ft • 19.2K - 19.2 Kbaud, Range of 2,000 to 2,500 ft • 4.8K - 4.8 Kbaud, Range of 3,000 ft Note This range is reduced by the amount of RF Noise present, obstructions, and the material properties of those obstructions.
3.2 Electrical Installation In this section wiring instructions are discussed for the various setup capabilities of the Base Radio. The subsections are as follows: 3.2.1 Electrical Specifications 3.2.2: Wiring Power to the Base Radio 3.2.3 Wiring RS-485 to the Base Radio 3.2.4 Wiring the RS-485/232 Converter to the Base Radio 3.2.5 Wiring the RS-485/USB Converter to the Base Radio 3.2.6 Daisy-Chaining Multiple Base Radios to Single RS-485/Power 3.2.7 Terminating Communications Wiring to the Base Radio 3.2.
Figure 3-2 Overall Wiring Schematic Warning! Explosions may result in death or serious injury. Do not remove the instrument cover in explosive atmospheres when power and/or communications are on. To begin the electrical installation first remove the explosion proof housing cover from the Base Radio, if you have not already done so. Point the Base Radio antenna away from you and look at the green PC Board found directly underneath the NEXT and ENTER buttons.
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 proper terminal blocks • Then plug the terminal blocks back into the proper jacks on the Base Radio.
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 the power supply wires, and the other wire in the “B” (Tx-/RX-) slot of the terminal block as shown below in Figure 3-5.
To configure the 485LDRC9 to the appropriate baud rate (38.4Kbaud), a set of dip switches must be configured. These switches can be found on the side of the converter. The first four switches should be in the ON position to indicate that the communications are half-duplex. The fifth switch should also be in the OFF position as this activates the 120 Ohm termination resistor within the converter. This terminator is only useful for long RS-485 buses, or other calculated circumstances.
7. Once Windows™ has detected the USB device, click NEXT. 8. Now connect the RS-485 cable to the converter’s DB-9 terminal. 9. Click START, SETTINGS, CONTROL PANEL, then select SYSTEM, and click on DEVICE MANAGER. Verify that the converter is listed in COM PORTS as “USB to Serial Adapter”. 10. The converter installation is now complete. The PORTS section of the DEVICE MANAGER, mentioned in step 9, shows the new COM PORT number next to the “USB to Serial Adapter”.
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 DIN rail mounted 15W power, it is suggested that no more than three Base Radios be tied parallel to this supply.
Figure 3-8 Daisy-Chaining RS-485 to Multiple Base Radios 3.2.7 Terminating Communications Wiring to the Base Radio RS-485 is capable of maintaining communications over a maximum distance of 4000 feet. In most (and we recommend all) situations the unit that comprises an “end” of an RS-485 network should be terminated by a resistor wired across the A and B wires. In the case of a daisy-chained application the end unit should be terminated.
(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 across the A and B wires, as needed. An example of this is shown in Figure 3-10. Figure 3-10 Example of Correct Termination Resistor Setup 3.2.
4 General Configuration This section discusses the generalities around configuring the Base Radio via the NEXT and ENTER buttons. The subsections are as follows: 4.1: Base Radio Displayed Messages 4.1.1: The Read Only Sequence 4.2: Overall Configuration Menu Map 4.3: Setting the User Password 4.1 Base Radio Displayed Messages The Base Radio should be on if power is being supplied (See Section 3.2: Electrical Installation).
Figure 4-2 The Read Only Sequence 4.2 Overall Configuration Menu Map A complete Base Radio Menu Map is shown in Appendix B. Below is an overall view of the configuration menu to aid the user in setting up the Base Radio for proper operation.
Note The user must enter a four-digit password to enter the CONFIG and DIAGNSE. The FACTORY menu is for factory use only. The default user password is 0000. For more information on the password see Section 4.3. 4.3 Setting the User Password Each Base Radio has a password that will lock out undesired users from making changes to the Base Radio. Any user may still view some of the Base Radio settings by pressing the ENTER key during the Operations Sequence and viewing the Read Only Sequence.
5 Configuring the RF Communications In order for the Base Radio and the Transmitter to communicate they must be on the same RF Channel, and must be transmitting at the same Baud Rate. All Transmitters and Base Radios are set to RF OFF default configurations at the factory, and must be field configured for proper operation. The subsections are as follows: 5.1: RF Channel Selection 5.2: RF Baud Rate Selection 5.
5.2 RF Baud Rate Selection The RF Baud Rate refers to the speed at which the Base Radio and Transmitters communicate. There are three selectable settings with the quickest update times and longest communication ranges listed below: • 4.8K • 19.2K — Rate of 19.2 Kbaud (Update every 5 seconds) — Range of 2000 ft to 2500 ft (Line of Sight) • 76.8K — Rate of 76.8 Kbaud (Update every 1 second) — Range of 500 ft to 750 ft (Line of Sight) — Rate of 4.
5.3 High RF ID Setting The Base Radio uses this parameter along with the RF CHAN and BAUD RT parameters to set up communication with Transmitters. This setting should be a number between 1 and 100 corresponding to the Transmitter with the highest RFID on the system. Any Transmitter with an RFID set above the HI RFID setting will not communicate with the Base Radio. The factory default is 001. Figure 5-3 High RFID Setting Note that the Output Modules with firmware prior to 1.
6 Configuring the Modbus Communications The subsections are as follows: 6.1: Base Radio Setup 6.1.1: Modbus Baud Rate Setting 6.1.2: Modbus Device ID Setting 6.1.3: Modbus Parity Setting 6.1.4: Modbus Mapping Mode Setting 6.2: Modbus Communication Protocol 6.3: Modbus Commands 6.3.1: Command 03-Read Holding Registers 6.3.1.1: Base Radio Holding Registers 6.3.1.1.1: Base Radio Device Type Holding Registers 6.3.1.1.2: Base Radio Device Status Holding Registers 6.3.1.1.
distance. If you encounter communication problems between the Base Radio and server computer or existing system, try a slower baud rate setting. Once you have determined the Modbus Baud Rate you wish to use, follow the Base Radio menu map shown in Figure 6-1 to configure the Baud Rate. The factory default is 19.2 K. Figure 6-1 Menu Map to Modbus Baud Rate Setting 6.1.2 Modbus Device ID Setting The Modbus Device ID allows a PLC or DCS to find the proper Base Radio on a RS-485 Network.
• Base Radio with Modbus device ID 001 ⇒ Transmitter with RF ID 1 is found at Modbus device ID 002 ⇒ Transmitter with RF ID 2 is found at Modbus device ID 003 ⇒ Transmitter with RF ID 3 is found at Modbus device ID 004 • Base Radio with Modbus device ID 101 ⇒ Transmitter with RF ID 1 is found at Modbus device ID 102 ⇒ Transmitter with RF ID 2 is found at Modbus device ID 103 ⇒ Transmitter with RF ID 3 is found at Modbus device ID 104 More detail about the registers at each address, and their meaning, ca
6.1.3 Modbus Parity Setting The Modbus Parity distinguishes which type of parity is used to validate 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. Selecting a parity of NONE will automatically include two STOP bits as per the Modbus communications specification. Follow the Base Radio menu map shown in Figure 6-3 to configure the parity.
Follow the Base Radio menu map, shown in Figure 6-4, to configure the mapping mode. The factory default is the Device ID mode. Figure 6-4 Menu Map to Modbus Mapping Mode Setting 6.2 Modbus Communication Protocol The Base Radio connects to the Host (Master) system using Modbus over a serial RS485 line. The Base Radio supports Modbus RTU transmission mode at baud rates of 9600, 19200, 38400, 57600, or 115200 baud with even, odd, or no parity and 8 data bits.
device ID. The Base Radio uses register addresses 1 through 10 with each subsequent group of 10 registers used by a Transmitter. The RF online/offline status of a Transmitter can be determined through a number of different sources. In the Base Radio holding registers, a count of the current number of online Transmitters can be found at address 00004. Also the individual online/offline status of each Transmitter is stored in the Base Radio holding registers at addresses 00005, 00006, 00007, and 00008.

total from the subtraction and subtract the next largest number possible and so on until the result is zero. Each value that was used in the subtraction indicates that the Transmitter is online. For example: The On/Offline Status holding register contains the value 15. In this case the largest value we can subtract is 8, which leaves a result of 7. Now we can subtract 4 from 7 and get 3. Now subtract 2 from 3 and we get 1. Finally we subtract 1 from 1 and get 0, so we are done.
