Check the modulation level - if the modulation level is low, adjust the MPX output level on your audio processor (or stereo generator). The maximum modulation should not exceed 75kHz. 8. Check the documentation that came with your audio processor on how to set/check the proper pilot injection level. In this setup, the stereo multiplex is generated by an external stereo generator and is fed directly into the transmitter exciter of the transmitter stage. Note that the transmitters onboard processing will have no effect on the signal in this configuration. Transmitter with an external audio processor and RDS (inline connection) 6.2.3 1. Place the transmitter in a well ventilated space. 2. Connect the antenna to the RF output connector on the back of the transmitter. 3. Connect the MPX output of your audio processor (or stereo generator) to the MPX input of your RDS encoder. 4. Connect the MPX output of your RDS encoder to the MPX 1 input on the back of the transmitter. 5. Plug the power cord into the power supply module on the rear panel of the transmitter. 6. Connect the required remote control / monitoring ports (Ethernet, RS232, Alarms/Triggers Port). In the RF Settings menu, set MPX Source to MPX Input 1. 7. 8. Once the transmitter is operating, set the correct carrier frequency and power from the RF settings menu. Check reflected power is OK. 9. Check the modulation level - if the modulation level is low, adjust the MPX output level on your audio processor (or stereo generator), RDS encoder. The maximum modulation should not exceed 75kHz. 10. Check the documentation that came with your audio processor on how to set/check the proper pilot injection level. 11. Check the documentation that came with your RDS encoder on how to set/check the proper RDS injection level. In this setup, the stereo multiplex is generated in the audio processor, it is then fed through the RDS encoder where the RDS subcarrier is added. It is then fed directly into the transmitters exciter. Note that the transmitters onboard processing will have no effect on the signal in this configuration. Also note that the V3 transmitter includes an on-board RDS encoder so unless you have requirements particular to your existing RDS coder, you do not have to use an external unit to achieve RDS/RBDS. 6.2.4 Transmitter with an external audio processor and RDS (sidechain connection) 1. Place the transmitter in a well ventilated space. 2. Connect the antenna to the RF output connector on the back of the transmitter. 3. Connect the MPX output of your audio processor (or stereo generator) to the MPX input on the back of the transmitter. 4.

Connect the MPX output of your RDS encoder to the SCA input on your audio processor. 6. Plug the power cord into the power supply module on the rear panel of the transmitter. 7. Connect the required remote control / monitoring ports (Ethernet, RS232, Alarms/Triggers port). 8. Once the transmitter is operating, set the correct carrier frequency and power from the RF settings menu. Check reflected power is OK. In the RF Settings menu, set MPX Source to MPX Input 1. 9. 10. Check the modulation level - if the modulation level is low, adjust the MPX output level on your audio processor (or stereo generator). The maximum modulation should not exceed 75kHz. 11. Check the documentation that came with your audio processor on how to set/check the proper pilot injection level. 12. Check the documentation that came with your RDS encoder on how to set/check the proper RDS injection level. In this setup, the audio stereo multiplex is generated in the audio processor. The RDS data is fed into the audio processor where it is combined with the audio multiplex. This combined signal is fed directly into the transmitter exciter. Note that the transmitters onboard processing will have no effect on the signal in this configuration. This is the best connection in terms of pilot and RDS subcarrier phase synchronization and MPX spectrum cleanliness, if youre not using the V3s internal RDS and stereo generators. Select whether you require the unit to send the FSK ID every hour. If enabled, enter the FSK ID (applies only to translator application in the USA). Set the 100% modulation level: This will usually be 75kHz deviation and should only be adjusted under special circumstances and then with caution. Set the desired Frequency. Note that the frequency displayed in the status box will flash for a few seconds, indicating that the system is out of lock and has not yet reached that frequency. Once locked, the display will become steady. Set the required Power. The system will take time to ramp the power to the selected value. During this time, the value displayed in the status box will flash. 7.1 RF Setup Note: Never power on an FM transmitter without a suitable antenna or dummy load connected. The V3 transmitters protection circuitry will prevent any internal damage, but it is not advisable to run a transmitter without a load connected. 7.1.1 Basic setup 1. 2. 3. 4. 5. 7.1.2 Power Scheduler This feature will switch the output power of the unit to an alternate value set in Power Scheduler | Power during the selected time interval. This is to allow you to lower the power of the transmitter, for example at night, to reduce power consumption. To set up this feature, enter the Power Scheduler sub-menu:

1. 2. 3. 4. 5. Current time is the system time. This is displayed here as a reference for use when setting the start and finish times. It can be adjusted if required. In Power set the power that the unit will switch to during the scheduled interval;

RF Mute must be switched to off once the unit is set up, to allow it to transmit. Set the finish time, when the unit will switch back to its normal power level;

Set the start time at which the unit will switch to this power level;

Set Enable to On. The power scheduler is now running. Internal/External Internal/External Determines whether to synch to an external 1pps reference. 0-359 degrees, to allow the stereo pilot to be synchronised with that of other transmitters in the SFN. Determines whether to use the transmitters internal 10MHz ref, or to accept an external reference from, for example, a GPS receiver. Allows the audio to be delayed by up to 20mS in 1uS steps, to synchronise audio with other transmitters on the SFN. 7.1.3 Synchronisation The V3 transmitter includes support for synchronizing with either a 10MHz, or a 1pps external timing signal, for use in a Single Frequency Network. The Synchronisation sub menu contains the following items:

10MHz ref:

Internal 10MHz trim: Allows the internal 10MHz ref to be trimmed +/- 10ppm. 1PPS synch:

7.2 Audio Settings The Audio Settings menu contains the following parameters:

Audio Input:

D-A Failover:

Analog Ref Level:

Analog refers to the left and right XLR connectors, Digital refers to the AES/EBU digital RJ45 connector, and Tuner refers to the optional internal tuner card, if the transmitter is configured as a translator (or rebroadcaster). If the source is MPX over AES then select Digital; in this case the digital audio connector is reconfigured automatically to receive MPX over AES. This feature could, of course, be used to provide a backup audio source to the V3 transmitter. When enabled (and when Input Source is set to Digital), the unit looks for an input at the digital input connector; if a viable AES-EBU signal is not present, it will switch to the analog XLR inputs. Set to the reference level of your facility, i.e. its nominal operating level. So if your mixing desk, for example, runs at around +4dBm, set this to +4. Off / On. [to be added in a firmware update]

Analog/Digital/Tuner. Set to the reference level of your facility, as above. For example, if you run your digital mixing desk so that it peaks at -10dBfs, set this to

-10dBfs. off/50/75uS this affects the stereo generators pre-emphasis, and that of the pre-emphasised limiting employed in the audio processor. Set to suit that used in your part of the world; generally 75uS in the US and 50uS rest of world. When off, the processor is bypassed use this setting if feeding audio to the V3 transmitter from an external audio processor. If youre using the optional internal tuner with the V3 transmitter configured as a translator or rebroadcaster, you will probably want to bypass the audio processor, because presumably the receive audio is already processed. on/off. Digital Ref Level:

The V3 transmitter features a 4-band audio processor built in as standard. The processor takes its input from the Digital or analog input connectors. The following items allow setup of the processor:

Audio Processor:

The content and function of the presets is similar to those used in the BW audio processor DSPXmini Encore. Please refer to the manual for that product for a fuller description of audio processing techniques and applications. The presets have been designed to represent processing texture appropriate to the format after which they are named; However dont be afraid to use a differently-named preset to your format, if it sounds better!

Allows fine trim of overall audio level, and right channel only, to compensate for L/R imbalance. Audio Trim:

Note that if you set MPX Source (in RF Settings) to be MPX Input 1 or 2, the exciter is fed directly from these rear-panel connectors, and the output of the audio processor and internal mpx generator is ignored. However, the audio processor and mpx generator are still running, and the generated mpx signal can still be routed to the MPX 1 and or 2 output connectors. Bearing this in mind, if you wish to use an external RDS generator which needs to be fed with an mpx signal, you can route the mpx output from the MPX OUT 1 connector to the external unit, and loop back to the V3 transmitters MPX 1 input connector. In this case, you would set Input Source to MPX Input 1. The following diagram may help to explain the audio routing available:

7.3 MPX The V3 transmitter incorporates a stereo coder, otherwise known as an mpx generator

(mpx meaning multiplex, sometimes known as composite). The stereo generator includes a composite clipper. With a drive setting of 0dB, this has no effect; above that it will become active and clip the mpx signal. The clipper contains RDS/SCA protection filters, also there is a pilot protection filter option. The audio clipper protects the mpx generator from peak excursions and overshoots in the source audio. It is distortion-cancelling and anti-aliased. Furthermore, there is an overshoot compensator which handles any overshoots from the main clipper, and restricts the audio bandwidth to 15kHz. Note: The mpx generator is fed from the audio processor; the selection of which input to use is made within the Audio Settings menu (see section 7.2). Pilot Level MPX2 In Level MPX1 In Level As above, for mpx input 2;

Level adjustment of this output;

RDS Level Adjustment for external mpx input 1 reference level;

Level of the 19kHz stereo pilot, in % of total deviation;

These menu items are reproduced for the MPX 2 outputs. MPX1 Out Source MPX1 Out Level Determines what signal is available on the MPX1 Output bnc connector: MPX (internally generated, including RDS if used), Pilot (the 19kHz stereo pilot), RDS (the internally generated RDS signal, Ext 1 and 2 a loop of the signals being presented to the MPX 1 and 2 input connectors;

7.3.1 MPX generator settings The mpx generator menu contains the following sub-menus:

Inputs/Outputs Generator 7.4 RDS encoder The V3 transmitter incorporates an RDS (RBDS in the US) encoder as standard. This module allows full dynamic control of all RDS parameters, such as PI, PS and RT

(Program Identifier, Program Service station name, and Radio Text). Please note: It is possible to send data to the RDS coder via the RS232 port, or via the Ethernet connection. If this is in use, the RDS coder treats this as locally-generated. Note that these two settings are based on the 100%

Modulation setting, in RF Settings. This is usually, in FM radio, 75kHz. Therefore a standard value of 9% pilot will produce 6.75kHz deviation, a setting of 3% RDS level will add a further 2.25kHz deviation, leaving 88% for audio. If your jurisdiction allows greater than 100% modulation for sub-carriers above 38kHz, you will need to increase the 100% Modulation setting and recalculate these figures.

based processing system which improves stereo performance in less than perfect signal conditions. On/off we recommend on. Triggers 7.6 BW Broadcast V3 transmitters have a comprehensive monitoring and control system consisting of 3 alarms and 4 triggers. Pin 2 of the connector is hardwired to RF mute. Connecting this pin to ground will mute the transmitter. The alarms and triggers port can also be used to control the unit through a telemetry interface system. Trigger pins are designed to work with relay contacts to ground or 5 V drivers able to sink 15 mA (per trigger pin). GPIO / Parallel remote control port pinouts Triggers are used to control certain parameters in the V3 transmitter using pins on the GPIO / Parallel Remote Control connector (see page 10). To fire a trigger, the pin must be pulled low. There is an option in the Triggers menu, RF Mute Mode. This allows an external trigger to mute the RF to be either toggle (i.e. a momentary signal) or level a continuous signal which while held, will keep the transmitted RF muted. 7.6.1 To set up a trigger:

Connect the required trigger pin to the required source. Make sure that the voltage and current levels are compatible. Navigate to the Triggers menu item and enter the required trigger

(Trigger1,...,Trigger 4). Set Enable to on. Select the Action that the trigger will perform. Options are: Frequency Up, Frequency Down, Power Up, Power Down, RF Mute and Reboot. Frequency Up, Frequency Down, Power Up, Power Down and reboot will perform the action on falling edges of the signal on the trigger pin. 1. 2. 3. 4. 5. 6. 7. If you require email alerts, set Send e-mail to Yes. Make sure e-mails are setup correctly (Refer to the e-mails section in this manual). If Send e-mail is set to Yes, enter the (ON) Message that the trigger will send when fired. Send SNMP Trap will cause an SNMP trap to be set, per the settings in the System

| SNMP menu. 7.7 Alarms Alarms on the V3 transmitter indicate that a failure condition exists. They can be set to activate on modulation level, forward power, reverse power and PLL lock fail. Upon triggering, they will toggle the relevant pin on the GPIO/Parallel connector. They write to the system log and send an e-mail if required. Alarm pins can be configured as open-collector outputs (when working as alarms) or as analog outputs (for reporting system parameters as analog voltages). When used as alarms, 10 kOhm external pull-up resistors to 12 V should be placed on each pin to be able observe voltage changes on the pins. 7.7.1 1. To set up an alarm pin as alarm:

If required, connect the required alarm pin to the external measuring equipment. Observe correct current and voltage ratings. Note that an external pull-up resistor may be required. 2. Navigate to the Alarms folder and then enter the Alarm folder that you require

These are: RF Status, Audio Status, Unit Status, Trigger Status, Trigger Config, Alarm Status, Alarm Config, Location, Contact, Date and Time, Uptime, Network, Web Portal, Telnet, RS232, System Details. A graphical representation of the Audio Meters - Input, AGC, Limiters, Output, MPX. This brings up a box with a collection of all the logs stored in the unit. The latest log (todays log) is displayed by default. Older logs can be selected from the list. If the unit has been switched on all the time, LX.log.1 corresponds to yesterdays log, LX.log.2 corresponds to the log written two days ago and so on. Note that if the unit is switched off, It will not write to the log and it will not create a new log file for the number of days it is off, so the older log files in this case will correspond to previous logs (written several days ago). Another way of accessing the logs, which may be useful in some cases where the log file contents need to be copied, is by browsing to a specific URL:

http://IPAddress/LX.log For example, for todays log: http://192.168.5.32/TLX.log Yesterdays Previous logs: http://192.168.5.32/TX-V2.log.x log:http://192.168.5.32/TX-V2.log.1 This option allows you to upgrade the firmware of the unit. Click on Choose File and select the desired upgrade.dat file. Then click update and wait while the unit receives the new SW and upgrades the system. The webpage will refresh in 5 minutes. The upgrading process may be finished in two minutes so try refreshing the page after this time. Software upgrade files can be downloaded from http://www.bwbroadcast.com This option resets the unit, bringing all parameters to their default value. Network settings are not affected. Clicking this button closes the active web remote session. All the controls in the transmitter can be found in this section. These are the same options that can be found in the front panel control system on the transmitter itself.
