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...
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. Unpacking Remove the Packing List and check off the actual equipment received.
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: Wire 24VDC power to the Base Radio using the power terminals on either the WMT or the Modbus connection.
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.
The Honeywell Base Radio is a rugged device, which provides optimal performance when installed with careful consideration. Installation practices greatly affect the life that you can expect from your Honeywell Base Radio. The main considerations for installation are covered below.
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 •...
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...
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.
3.2.2 Wiring Power to the Base Radio The Honeywell Base Radio is designed to use a 24 VDC power supply at a minimum of 0.5 Amps. Honeywell offers a DIN rail mountable 100-240VAC 50/60Hz to 24VDC transformer for this purpose, AIC #. For more information, contact your Honeywell Representative.
3.2.4 Wiring the RS-485/232 Converter to the Base Radio Honeywell offers an optically isolated, surge protected, DIN Rail mountable RS-485/232 converter, AIC #. Because there are many RS-485/232 Converters available, please see your converter’s instruction manual for details as this section will only discuss the wiring of the B&B 485LDRC9 converter.
Note The RS-485 cable should NOT be connected to the RS-485/USB converter before the converter drivers have been installed. Honeywell also offers a non-optically isolated RS-485 to USB converter. The USB Converter provides easy connectivity between the PC and standard communication ports, not requiring PC reconfiguration, assignment of IRQs, or jumper settings.
Once Windows™ has detected the USB device, click NEXT. Now connect the RS-485 cable to the converter’s DB-9 terminal. 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”.
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.
(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.
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 Base Radio Displayed Messages The Base Radio should be on if power is being supplied (See Section 3.2: Electrical Installation).
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. Figure 4-2 The Read Only Sequence Figure 4-3 Overall Configuration Menu Map...
The password is a four-digit password. The factory default is 0000. If you wish to select a different password, follow the Base Radio Menu Map shown in Figure 4.5 to change it. If you forget your password you must call your Honeywell Sales Representative to have it reset.
Once you are in the RF Channel menu, you can increment it by pressing the NEXT button. When selecting the RF Channel, do not choose an RF Channel that is currently being used by other Honeywell Wireless Systems as this can cause communication problems.
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 — Rate of 4.8 Kbaud (Update every 20 seconds) —...
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.
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...
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.

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 6-4, to configure the mapping mode. The factory default is the Device ID mode. Figure 6-4 Menu Map to Modbus Mapping Mode Setting Modbus Communication Protocol The Base Radio connects to the Host (Master) system using Modbus over a serial RS- 485 line.
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.
Subfunction Code Note that identical information is returned for any device ID that the Base Radio has control of (i.e. including Transmitters mapped to virtual device IDs when operating in the device ID mapping mode (See Section 6.2). 6.3.3 Command 11- Get Com Event Counter This command returns a two-byte status word and the device’s event counter.
6.3.6 Command 43- Read Device ID This command returns identification information relating to the device. The conformity level of this command is level 01, basic identification (stream access only). As with most of the other diagnostic commands, identical information is returned for any device ID that the Base Radio is controlling (including Transmitters mapped to virtual device IDs when operating in the device ID mapping mode).
