Each band selection will determine the frequenciesthat will be used in the hop patterns. This option is recommended if slave radio receipt of data is critical. The master will broadcast each message only once. This option is recommendedif slave receipt of data is not system-critical and higher network speed is necessary. An example of the window is shown in Figure This window will define a default serial port configuration for every radio in the network.
Ifany radio requires different serial port parameters than those defined here, it can be individuallyprogrammed see Paragraph 4. Each setting is discussed in greater detail below. If the serial port settingsdo not exactly match, the radio will not communicate correctlywith the connected serial device.
Baud RateThe baud rate determines the speed at which the serial port on the radio will send data tothe serial device connected to it. The baud rate is different from and independent of the overthe-airdata rate. The RAD -Link software allows the user to select baud rates of , , , , ,, or bps.
It is important that this value is matched up with the speed of theserial device that will be connected to the radio. ParityParity is an error detection method that appends a bit to the end of each packet to causethe number of high bits in a packet to be either even or odd.
There are three choices for the parity field. The usercan select between None no parity , Odd or Even. Data BitsThis determines how many bits will form each character of data.
The field is selectablebetween 7 or 8 data bits. This field must be set identically in both the radio and the serialdevice. Stop BitsThe stop bit is used to indicate the end of a character. Either 1 or 2 stop bits can be selected. This field must be set identically in both the radio and the serial device. Most serialprotocols use 1 stop bit. HandshakingHandshaking uses additional pins on the RS connector to ensure each device is readyto accept data prior to beginning a new transmission.
The transmitting device asserts avoltage on the RTS pin when it is ready to transmit, and the receiving device asserts a voltageon the CTS pin when it is ready to receive the transmission. This field can be set to Hardware or None. If hardware handshaking is enabled on theradio, it must also be enabled on the serial device. Refer to Section 3, Figure for more information on wiring radios to serialdevices that support handshaking.
Handshaking will prevent the buffer on the radio from overflowing when the serial port baudrate is faster then the over-the-air data rate. Handshaking becomes moreimportant at higher baud rates because of the difference between the over-the-air data rateand the serial port data rate.
Buffer ModeBuffer mode determines if the receiving radio buffers data before sending it to its serial port. The two options are Off Character or On Packet.
If Off is selected, the radio will immediatelysend data out to its serial port as soon as it is received over the air. If On is selected, the radio will buffer the data until a complete packethas been received before sending the data out to its serial port. This mode is required by theModbus protocol and must be selected when the serial device is using this protocol.
Keep thedata file in a location that is easily accessed and retrievableby anyone needing to configure or monitor the network. A window willopen showing the first radio to be programmed. From this window, a name and locationinformation for a specific radio can be entered. Configure Individual Radio Window4. NoteIt is a good idea to physically label the radio you wish to programwith its name and location information.
This will make iteasier to distinguish between the master, repeater and slaveradios during installation and commissioning. This is important if you ever need to replace or reconfigure aradio since a network has the capability of containing up to radios. If you have not doneso already, it is recommended that you physically label the radio with its name and locationinformation as well.
Because of this, it is important to make sure the file isavailable to anyone who will need to maintain or configurethe network. Once the upload is successfully completed, the messageshown in Figure will appear. Cycle the power on the radio to reset the timer. This feature was implemented to allow these radio models tobe compatible with legacy telephone modems for use in hybridnetworks which have both telephone and radio modems.
NoteSometimes the system cannot connect to the radio. If this occurs,a message will be displayed indicating the error. Refer toParagraph 4. At this time, remove the serial cable and connect it to the next radio. Repeat theprocedures outlined in Paragraphs 4. Once radio configuration is complete, the software will display a message indicating theradios are ready for installation in the field as shown in Figure Network Setup Complete Message4.
The Connection Helper window will open asshown in Figure Connection Helper WindowFollow the troubleshooting steps outlined below to establish communications with theradio. You may also follow the instructions in the Connection Helper window as shown inFigure If the radio has been powered on less than 5 minutes and the radio is connectedto the correct serial port, the PC may have different serial port settings.
From this window, you can add and configure individual radios. This method is only recommended for advanced users or those wishing to add radios to ordelete radios from an existing network.
The window will have fourtabs that will allow you to configure different aspects of the radio. The details of each tab aredescribed in the following paragraphs. Radio Configuration Window4. The Radio Name field allowsyou to rename the radio or select between the other radios in the Radio Profiles List. Values between 0and are possible for this field. Radio VersionThe version field indicates the software version running in the radio.
This field cannot beedited by the user. Selecting a Radio TypeThe Radio Type field allows you to select the type of radio you are using on your network.
These tabs are discussedin detail in Paragraphs 4. Selecting the Number of Times to Retry Failed MessageThis field allows the user to set the number of times a message will be retransmitted beforethe radio accepts failure and discards the message. A low number decreases the chancethat a failed message will get through to the recipient but does not tie up radio resourceswith a high number of retransmits.
A higher number will increase the chance that the messagewill reach the recipient but ties up radio resources for much longer in the event that therecipient is not operational or present. The radio will retransmit the message the specifiednumber of times before moving to the next transmit task.
Values between 0 and are possible. It is left to the user to decide how many times a transmission will be repeated beforethe transmitter accepts failure. This decision must be made based on what is most importantto the network: reliability or speed. Selecting an Auto-Routing ModeThe Auto-Routing option is available for radios that have been designated as either masteror repeater. It will notwork with other protocols. Auto-Routing works by monitoring the PLC address within each command and notingwhich slave radio transmitted the data.
The master radio then creates a table that correlateswhich slave radio is connected to the PLC. During the first round of polling, the master radiomonitors communications and builds the table. In subsequent polls, the master requests anacknowledgment that the target slave radio has received its message. If all retries fail, the master willgive up. NoteDuring initial bench testing, it is recommended that Auto-Routing be turned off.
This is recommended because anychanges made to radio IDs or PLC addresses may preventthe network from functioning until after a flush has occurredand new tables have been established. It isnecessary to reconstruct the table periodically in the event that a repeater has lost power orsuffered a failure and data has to be rerouted through a different repeater.
This field allows the radio to lock onto a specific radio such as the Masteror a Repeater or to any of the other radios in the system Roaming.
By choosing theroaming option, should a connection fail between two radios, the radio will search for otherradios in the network to move the data to the intended target. This parameter is not availablewhen configuring a master radio. With large networks networks may contain up to slave radios ,it may be difficult to remember where all the radios are located, their service history, radiousage, etc.
The Notes section provides a place for this information to be recorded separatelyfor each radio. Keep thedata file in a location that is easily accessed and retrievableby anyone needing to configure the network. Radio Configuration Window, Notes Tab4.
NoteRefer to Paragraph 4. Referto Paragraph 4. These fields control themain serial port and the emulation mode settings. NoteRS is a 2-wire, half-duplex standard whereas RSis a 4-wire, full-duplex standard. Neither protocols supporthardware handshaking. Once programmed, youwill no longer be able to program the radio through the RSport. This process isdescribed in the following paragraphs. Remove the plastic housing from the radio.
Set Switch 1 of bank 3 to the ON position. Ensure that all other switches are in their OFF positions. Apply power to the radio for 10 seconds and then remove power. Set Switch 1 back to the OFF position and reinstall the plastic housing.
NoteResetting the Main Serial Port may cause other settings tochange. Review all settings prior to programming the radio. Often you will need to use the Auto-Configure option describedin Paragraph 4.
Then whileholding the latches depressed, slidethe plastic housing down to exposethe DIP switches. Bank No. In installations where the radio will be connected to line power, full time operationis recommended. This will ensure the radio does not miss any messages while it isasleep. In installations where the radio must be battery powered, part time operation throughthe use of Sleep Mode is recommended.
A watchdog function will continue to operateoff of an internal battery. Although the radio will still sleep if all external power is removed, itwill not be able to wake and perform normal radio functions until external power is restored.
For this reason, removing power from a radio that is asleep is not recommended. The sleepmode settings are shown in Figure Setting the Radio TimeFigure The first is to highlight separately the firstand last two digits of the Time field and enter in a valid time in the range of This provides themost reliable communication at the expense of power consumption.
Values between 0 and seconds are possible. Use this mode when the radio is connected to a PLC and is operating offof battery power since it uses the least amount of power. Specify how long you wish the radio to sleep by entering avalue in the adjacent field. Values between 0 and 65, seconds are possible. NoteNo communications can occur with a radio when it is asleep,to include programming.
A radio can only be programmed,transmit or receive data when it is fully operational. Store to ProjectButtonFigure If the PC fails to connectto the radio, refer to Paragraph 4. Repeat the steps outlined in Paragraphs 4.
SeeFigure Project Wizard Welcome WindowFigure Troubleshoot Existing Installation Window4. When selecting this option, the PC must be connected to the master radio to enable thesoftware to access the network. If the PC cannot connect to the radio network, refer to Paragraph 4. Once the PC scans and retrieves the data from the network, you will be able to adjust theparameters by clicking on each of the radios in the spreadsheet.
The Radio Configurationutility will appear, allowing you to view and adjust network parameters. These windows are only available when a project is open. Additional shortcuts to common functions are available along the left side of the main projectwindow. NoteSome of the functions described in the following sections areonly available after the software has been registered.
This window lists each radio that has beenadded to the current project. The following are several functions that can be performed fromthe Radio Profiles List. Opening a Blank ProjectFigure This opens a new project with a single master radio in the Radio Profiles List. Deleting a Radio from a ProjectTo delete a radio from a project, right click on the name of the radio in the Radio Profiles Listwindow and select Delete Radio Configuration.
NoteSeveral radio functions are available either by right clicking onthe name of a radio and selecting the appropriate function, orby left clicking on a radio to highlight it and selecting the desiredfunction from the Radio menu located on the Menu Bar. Choose a directory and enter a file name. Opening a ProjectTo open an existing project, save and close any existing project and click File and selectOpen Project. Browse and select the file you wish to open.
An example of the report format is shownin Figure Example Report4. Click to select or deselectthe various program options you wish to turn on or off. The temperature scale canbe toggled between Fahrenheit and Celsius for monitoring. This will prevent unauthorizedchanges to the radio settings. Type in a password, then retypeit for confirmation. The password should be at least 4 characters or more in length andcan contain combinations of letters and numbers.
You canchange the settings manually to match the settings of the connected radio. The computerwill search through a list of possible serial port settings until a match is found.
Oncethe current settings have been determined, communication between the computer and radionetwork is possible. Clicking on this opens a new project and starts the project wizard. Clicking on this opens a dialog box to search for an existing project. Save this ProjectThis option saves the current project to a file. Add a Radio to Current ProjectClicking on this will add a new non-configured radio to the end of the project list. Generate ReportRefer to Paragraph 4.
Clicking on this starts the wizard to create a new network or modify an existing one. Start Network MonitoringNetwork monitoring retrieves diagnostic data from all radios in the network. This featurerequires a software license. See Section 10, Paragraph Stop Network MonitoringClicking this stops the retrieval of diagnostic data from the network.
Search Network for New Radio sThis feature will scan the radio network for any radios that may not be shown in the currentproject. Read Configuration From Radio This will download the parameters from the connected radio.
Edit Radio ConfigurationThis opens the configuration dialog box for the radio that is currently highlighted in the project. Edit Network ConfigurationChanging the network configuration affects all radios in the network.
It is also possible to change the network to allow or disallow repeaters. This is useful in environments where legacy devices may be operating in the sameband as the radio networks. The primary serial port is selected through the use of internal DIP switches. To change the primary serial port settings, press inward on the detents on either side of theradio underneath the terminal blocks and slide down the plastic housing to expose the DIPswitches.
Set the DIP switches according to the labels printed on the circuit board. Once the primary port has been specified, the other port automatically becomes the secondaryor remote diagnostics port with fixed port settings of 19,, N, 8 and 1. To access the DIP switches, press inward on theindents on either side of the plastic housing just below the terminal blocks and slide downthe plastic housing.
With power removed from the radio, adjust the DIP switches accordingto Figure Reassemble the radio and reapply power for the changes to take effect. SeeFigure for DIP switch settings. For example, ifthe master radio is programmed with a security ID other thanthe factory default, and the slave radio is programmed usingthe DIP switches, they will not be able to communicate witheach other because the security IDs will not match.
The remote diagnostics port is always the port located on the side of theradio with the DIN connector. A cable that adapts a 9-pin, D connector to the DIN connectorcan be ordered part number Alternately, if you wish to build your own cable, theconnections are shown in Figure They feature an 8-position rotary switch onthe top of each module for addressing. It can either accept powered loops orprovide the power for a loop. The power supply for the loops is common to the radios powersupply.
It can either accept powered loops or providethe power for a loop. Each current loop is optically isolated from each other. Internallythere are 4 DIP switches that determine what happens to each current channel if the radiolink is lost — either fail to 2 mA or maintain the last known value. Each input requires a voltage to trigger it. Eachchannel is optically isolated. Each output is a normally open dry contact. Internallythere are 8 DIP switches that determine what happens to each channel if the radio linkis lost — either fail open or maintain the last known value.
Internally there are DIP switches that determine the fail conditionof the outputs in a similar fashion as described in the above modules. A 5-position DIP switch inside themodule is used to set the mode of each channel, as well as the input impedance, coupling,speed, and input type single-ended or differential.
It is compatible with the following commonpulse generating devices. A 4-position DIP switch insidethe module is used to set the mode of each channel as well as the speed high or low. When acurrent signal is applied to one radio, its exact value is replicated at the remote radio, andsimilarly with discrete signals. In point-to-point emulation mode, there can be only one masterradio and only one slave radio. For example, if threeanalog input modules are connected to one radio, the other radio must have three analogoutput modules connected to it.
Refer to Section 4, Paragraph 4. Remove the plastic housing from the output modules and set the fail condition DIPswitches as desired for each channel. Refer to Paragraph 5. Wire the analog and discrete signals. Next, connect the antennaand apply power. Refer to Sections 3 and 9. There can beonly one master and up to slave radios. When data is sent into the master radio, it appearson the serial port of all slave radios.
Every device must have a different address programmedinto it. In this mode, themaster PLC controls all commands and initiates all requests for data. See Figure By using a request command Modbus or a message instruction AB , you can read and write to registers on each slaveradio.
A slave radio can alsofunction as a repeater for a more distant slave radio s. Whena command from the master PLC is broadcast through the master radio to all slave radios,the slaves will then read the address to determine if they should respond. Within each commandthere will be a read or write request to certain registers.
The RSSI is presented as a positivenumber. If a value of —dB is shown there is noradio link. The value for the master radio is the average of allthe slaves polled. The internal temperature is expressed indegrees Celsius and the power supply voltage in volts.
In the addressmaps above there are references to module numbers. These module numbers refer to theposition of the rotary switch.
Each module must have a different number. Pulse Input ChannelsIf the input channel is set to frequency mode, the value displayed in the corresponding registerwill be the input signal frequency in Hz kHz. The first LSW register keeps the currentcount up to 32, Refer to the address map in this section to determinethe correct register. NoteIf you have a pulse input channel set to counter mode, you mayneed to periodically reset the register to prevent overflow. Refer to the address mapto determine which register.
Pulse Output ChannelsIf the output channel is set to frequency mode, the value entered in the corresponding registerwill be the output signal frequency in Hz kHz. Because the MSW exceeds the maximumpulse frequency that the module can produce, any values written to it will be ignored.
If the pulse output channel is set to counter mode, each channel will have a bit register two consecutive bit registers assigned to it. The counter mode has two different types ofoperations: 1 absolute count; and 2 differential count. The two modes are described in thefollowing paragraphs. For example, if the previous value in the register was 5 and a new value of 15 iswritten, 10 pulses will be produced.
However, if a new value of 3 were written, thepulse module would produce enough pulses to wrap the bit register arounduntil it is reset to 0 and then delivers 3 more pulses. Therefore, the pulse registershould be cleared periodically. For example if a value of 10 was written to the pulse output register, 10 pulseswould be produced. If a new value of 5 were written, 5 more pulses would beproduced. To initialize absolute or differential counts, refer to the address map to determinewhich registers are used to control the operation mode.
Absolute mode is initializedby writing 0 to both control registers; differential mode is specified by writing1 to the least significant word LSW and 0 to the most significant word MSW.
This should be done with a singlemessage instruction. NoteWhen counter mode is selected, if the number of counts to bedelivered has not been completed before a new pulse countis written to the register, the new counts will be added to theexisting count. The options are Maintain Last State or Fault off,to a current value of approximately 2 mA By releasing the top part of the housing, you canaccess the internal DIP switches.
By releasing the top part of the housing, you can access the internal DIPswitches. By releasing the top part of the housing, you can access the internal DIP switches. Solid State SwitchBFigure Backup PowerThe digital pulse input module will retain its pulse count if power is removed, however, it willnot record any new pulses.
Terminals 5 and 6 of the module are used for connecting thebackup power supply to the module. If primary power through the bus connector from theradio is lost, the backup power supply will allow the module to continue to record pulses. The backup power terminals will not supply power to the transceiver or any other module onthe bus connector.
This would apply where there is aDC bias voltage added to the pulse input voltage, where the DC bias exceeds 3.
