DRAFTChapter 3 - Repeater Configuration 19 TDC-0613-000 10/04Communicating with a RepeaterEnding a Communication SessionAfter a short amount of time, all of the repeaters that responded to an all call will return to their programmed frequencies and continue to operate. To return a repeater to its normal operation prior to the timeout, do this:• From the Remote Unit Connection dialog, click With this ID.To return all of the repeaters that responded to normal operation, do this:• From the Remote Unit Connection dialog, click With All.4Press Enter to accept Digital mode. The All Call starts and available repeaters display in the Control Panel Remote Call list.5Select a repeater from the list and click Remote Connect. The Repeater Configuration dialog appears.Step ActionAvailable repeater
DRAFT20 Fixed Network Repeater Installation Guide TDC-0613-000 10/04Communicating with a RepeaterDisplay Current Configuration To display the current configuration of the repeater, do this.• From the Repeater Display group, click Configuration Data. The configu-ration of the selected remote unit displays.Parameter DescriptionRX Packet Type Indicates the message type that the repeater is lis-tening for: SCM, IDM or both.RX Mode Mode in which the repeater is receiving messages. Hop mode (random, sequence, or interleaved). Default is interleavedTx Mode Transmit mode determines the range of frequencies that the transmitter will use to communicate.•In-Band Communication happens between two specific frequencies. See TxI for more information.•Keep Away Communication happens any-where but between the specified frequency points. See TxK for more information.Repeater Indicates whether the repeater is forwarding raw messages. If set to off, the repeater is receiving ERT data but not forwarding that data on to a collector.Tx Power Level Amount of power that the repeater uses to forward messages. Default is 20Local ID The repeater identification number.Radio Frequency BandABIn-bandRadio Frequency BandABKeepAwayKeepAway
DRAFTChapter 3 - Repeater Configuration 21 TDC-0613-000 10/04Communicating with a RepeaterDigital Mode/Narrow Band Indicates the Band mode that repeater is connected in. Digital mode is used for configuration. Narrow band is used during general repeater operation.FPGA Reset Time Prevents radio frequency from wandering over time by resetting it periodically. Multiplied by 10, the number of seconds between receiver resets. Bubble-up Period The frequency of diagnostic message bubble-up. Multiply by 10 to get number of milliseconds.This parameter is used for Itron diagnostic purposes.Rx Start End Dwell Size Starting frequency, ending frequency, dwell length of time, and size (see Display Receiver Parameters on page 24 for more information).TxI Start End Size Trasmit in-band settings. •Start - Point A frequency•End - Point B Frequency•Size - The number of hops or steps between point a and point b. The higher the number of steps, the more granular the data.TxK Start Stop Go End Size Transmit keep away settings. •Start - Indicates the start of the band•Stop - The beginning of the keep away. Point A in the example.•Go - The amount of band to skip. Point B in the example.•End - End of the band•Size - Number of hops or steps in the entire band. The higher the number of steps, the more granular the data.Parameter DescriptionRadio Frequency BandABIn-bandRadio Frequency BandABKeep-Away
DRAFT22 Fixed Network Repeater Installation Guide TDC-0613-000 10/04Setting Communication ModeSetting Communication ModeOverview When communicating with the ERT endpoint, the repeater transmits and receives using a 900 MHz radio. The repeater transmitter and receiver can each be configured to operate on a single receive frequency or to periodically switch, or hop, to a different frequency that is defined in a hop table. For each entry in a hop table, the repeater will transmit or receive at the defined frequency, dwell at the frequency for the specified time (in milliseconds), and then hop to the next table entry frequency. Hopping can be either sequential or random.Using In-Band Transmitter Mode In-band transmitter mode narrows the frequency band by specifying two points in the band and limiting transmission to frequencies between those two points.To display the current settings for in-band mode, do this:•Click Display. The settings display in the Data view.To edit the In-Band settings, do this:•Click Edit. Change the settings as desired.To set repeater to use in-band mode, do this:•Click Apply. The repeater will use the in-band mode settings.Using Keep-Away Transmitter Mode Keep-Away transmitter mode narrows the frequency band by specifying two points in the band and limiting transmission to frequencies outside those two points.To display the current settings for Keep-Away mode, do this:•Click Display. The settings display in the Data view.To edit the keep-away settings, do this:•Click Edit. Change the settings as desired.To set repeater to use keep-away mode, do this:•Click Apply. The repeater will use the in-band mode settings.Set Bubble-Up Period You may change the diagnostic bubble-up message frequency, if desired. To set the bubble-up period, do this:•Click Set Bubble-up Period. Enter the new bubble-up rate.Change Transmitter Power Setting The radio transmission power setting may be altered according to the needs of your deployment. For example, you may wish to reduce radio power for a repeater that is close to a collector to minimize radio “noise.” To change the transmitter power setting, do this:•Click Transmit Power. Enter a new transmission power.Enable/Disable Message ForwardingFor diagnostic purposes, you may wish to prevent a repeater from forwarding, or repeating, the messages it receives from an ERT endpoint. To enable or disable message repeating, click Repeater Off or On.
DRAFTChapter 3 - Repeater Configuration 23 TDC-0613-000 10/04Configuring Receiver RadioEnable Duplicate Filter By default, a repeater does not filter duplicate readings and repeats all readings. To enable the duplicate filter, click Duplicate On. Only new readings will be for-warded.Configuring Receiver RadioSet Receiver Parameters The Set Receiver Parameters option displays the current receiver settings and allows you to adjust those settings as needed. To set the receiver parameters, do this:• From the Receiver group, click Set Parameters. The current parameters display in the data window. Enter the new parameters, as needed.View Receiver Statistics Use Receiver Statistics to view the current state of receiver settings.Receiver Parameter DescriptionStart The starting frequency for the receiver.End The ending frequency for the receiver.Dwell The number of milliseconds the repeater receiver will remain at this frequency. Multiply this value by 10 for the number of milliseconds.Steps The total number of steps between Rx Start and Rx End. Receiver Parameter DescriptionSeconds since clear Indicates the number of seconds that have passed since the last reboot. To avoid data corruption, the repeater periodically reboots to its initial state.RX Packet Type Indicates the type of packets that are repeated: SCM or IDM message packets, or both types.SCM Good/Bad RX Indicates the number of normal and corrupted SCM message packets received since the last reboot. IDM Good/Bad RX Indicates the number of normal and corrupted IDM message packets received since the last reboot. CMD Good/Bad RX Indicates the number of successful and unsuccessful commands issued since the last reboot.

The version of the selected remote unit displays.Display Receiver Parameters The Display Receiver Parameters option displays the current receiver settings. To view the receiver parameters, do this:• From the Receiver group, click Display Parameters. The current parameters display in the data window.Reset Receiver If needed, you may manually reboot the repeater. The reset command reboots the repeater and radio. To reset the receiver, do this:•Click Reset. The repeater will reboot.Calibrate Receiver Calibration returns a repeater to its default configuration. To calibrate a repeater, do this:•Click Calibrate. The repeater returns to original factory settings and reboots.Parameter DescriptionApplication Version Firmware version of the repeaterBuild Date and Time Save date and time of the firmware versionRepeater Type Type of repeater - pole-mount or sleeve-mountConfiguration Current configuration of the firmwareReceiver Parameter DescriptionStart Starting frequency for the receiverEnd Ending frequency for the receiverDwell Number of milliseconds the repeater receiver will remain at this frequency.
