The TX-V2
The BW Broadcast TX-V2 is the latest development in a high specification range of FM transmitters over 15 years in the making.
Its broadband ”no-tune” design allows 87.5 - 108MHz operation without requiring tuning or
calibration. The inclusion of four-band DSPX audio processing means stations without a dedicated processor sound great, right out of the box. Those who already have external processing benefit from BW Broadcast’s unique dual-loop virtual VFO exciter and field proven
ultra-low distortion modulator integrated into a great performing, highly stable FM transmission system.
Features such as slide-in power supplies, and unique solder-free Gold-Clamp transistors (on
most models) make in-field maintenance simple.
A high resolution OLED screen displays RF, audio and system parameters. The control wheel
and three front panel buttons allow easy navigation of the menus. Help tips for every parameter make setup simple.
Every TX-V2 Transmitter features a LAN connection for Ethernet local or remote control. The
LAN connection also supports SNMP, telnet, and email alerts via either SMTP or BW Broadcast’s mail server. Where a LAN connection is not available, the RS232 connection can be
used.
Intelligent alarms and email alerts ensure busy engineers can manage their stations with minimal intervention. A real time clock and comprehensive logging is available for those who
like to see more detailed status. Also present are 4 rear panel opto-isolated triggers that allow external equipment to control the transmitter.
It is advised that this manual is read to learn all of the advanced features of the TX-V2 Transmitter.

Installation
6.1 Quick Start
N.B. Never power on an FM transmitter without a suitable antenna or dummy load connected.
The V2 Transmitter’s protection circuitry will prevent any internal damage, but it is not advisable to run an FM transmitter without a load connected.
Setting up a V2 Transmitter couldn’t be any easier. First connect either analogue audio to
the left and right back panel connectors (10 and 11), digital audio AES/EBU into the left hand
connector (10) or feed the MPX input (13) from an audio processor. Connect the RF output
(18) to a 50Ohm antenna of the correct power handling capability. Connect the required
remote control / monitoring ports (Ethernet, RS232, Alarms/Triggers Port).
The transmitter’s frequency and power are both set from the RF Settings menu:
Input selection, pre-emphasis, processing and the stereo parameters are set in the audio settings menu:
Input Selects analog or digital input to the transmitter’s built in stereo encoder/audio processor. For analog, connect to left and right XLR Inputs. For digital, connect an AES/EBU connection to the left hand XLR input.
Pre emphasis Sets pre emphasis to off, 50µS (Europe/Japan) or 75µs (Americas).
Processing Preset Selects the processing preset on the integrated 4-band DSPX audio processor.
25
Encoder Selects the stereo generator mode, from either: Stereo, Mono L+R, Mono L, Mono R
and Swap L + R.
MPX Source Selects if the MPX source for the exciter is internal or external. If using the V2 transmitter with no external equipment (RDS, audio processor etc) then set to internal. If using any
external equipment set to external. When set to internal, the MPX In and MPX Out connectors
are internally connected. which routes the internal stereo generator directly to the exciter.
When set to external, the internal the internal stereo generator and audio processor are still
functioning, but the MPX in and MPX out connections are not internally connected, allowing
MPX signals to be routed to and/or from external equipment.

The about menu contains the version numbers of the different parts of the system. These values should be available when contacting support.
7.5.13
Reboot
This parameter will reboot the unit.
7.5.14
Factory Reset
Performs a factory reset, setting all the parameters to its default value except for Network settings. All user changes will be lost.
7.6 Web Remote
V2 Transmitters provide a graphical web based interface for ease of use and control. This
can be accessed by navigating to the IP address of the unit in any standard web browser.
After entering the login details for the unit, the user can then read and write all parameters
and also perform firmware upgrades. All parameters are saved and updated dynamically
as they are changed in the remote. The system serves a mobile-optimised version when accessed from a mobile web browser.
7.6.1 Autentication
Browse to the IP of the unit (Navigate to System ⇒ Ethernet in the FP. Refer to the Ethernet
section in this manual to set up Ethernet). You will be required to authenticate by entering the
password. This password must match the one selected in the FP (System ⇒ Users ⇒ Password). The default password is ”pass”.
41
7.6.2 Web Remote Interface
The user interface is divided in several sections: Status Bar, Alarms and Notifications, Navigation Bar and Transmitter Controls.
Status Bar
The Status Bar displays the current status of the Transmitter (Frequency, FWD power in Watts,
REV power in Watts, peak Deviation in kHz).
Alarms and Notifications
The Alarms and Notifications Section displays the status of the alarms and the number of
times that the alarms were fired in the last 24 hours. The Notifications section reports the number of emails sent by the unit within the last 24 hours.
Navigation Bar
This Bar Contains shortcuts that bring up the relevant windows connected to the feature:
42
A Status/Config
This Brings up a box with all the relevant Status and configuration settings. There 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.
B Audio Meters
This Brings up a box with a graphical representation of the Audio Meters (Input, AGC,
Limiters, Output, MPX).
C Log Files
This brings up a box with a collection of all the logs stored in the unit. The latest log (today’s log) is displayed by default (TX-V2.log). Older logs can be selected from the list. If
the unit has been switched on all the time, TX-V2.log.1 corresponds to yesterday’s log,
TX-V2.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/TXV2.log
For example (IPAddress = 192.168.5.32). For today’s log:
http://192.168.5.32/TX-V2.log
Yesterday’s log:
http://192.168.5.32/TX-V2.log.1
Previous logs:
http://192.168.5.32/TX-V2.log.x
D Reboot
This will reboot the unit.

7.9 Parameters
This section contains a list of all the parameters in the unit and all of their possible values. This
should must be used as a reference when controlling the unit via text based access (Telnet
or Serial RS232) or the Web API.
When setting the value of a parameter, trying to set a value greater than the allowed maximum will result in the maximum value being set. When setting a value less than the allowed
minimum, the minimum value will be set. When setting a parameter to a value which does
not align to the step size of that particular parameter, the closest lower value multiple of the
step size will be set.
Setting values allows the use of prefixes. available prefixes are: m (mili = *0.001), k or K (kilo =
* 1000), M (Mega = * 1000). These can be used when setting a parameter value. E.g.:
Setting the frequency to 98 MHz:
”set transmitter.frequency 98M”
”set transmitter.frequency 98000K”
”set transmitter.frequency 98000000”

Parameter Guide
8.1 RF Settings
8.1.1 Frequency
This sets the transmission frequency. The range for this parameter depends on the Band. For
normal Band II transmitters the range is 87.5 MHz to 108 MHz. The normal step size is 50 kHz.
Other frequency ranges and step sizes are also available on request. Please contact a sales
representative for more information.
8.1.2 Power
This sets the RF output level in watts. The range and the step size for this parameter depend
on the model of the transmitter. The following table lists all the ranges for the different models
in Watts:
Transmitter Model

Note that when setting the power, the unit will automatically adjust the power output to
reach the selected value. This may take a few seconds. During this time, the FWD power indicator in the Status Box will flash to indicate that the unit is still adjusting to reach the selected
power.
8.1.3 MPX Source
This selects the source for the exciter. Options are Internal or External. Internal selects the internal generator, i.e. the output from the internal audio processor. This option must be selected when the digital or analog inputs are used. External selects the MPX BNC input. This
option must be selected when the transmitter is used with an external audio processor connected to the MPX BNC input.
62
8.1.4 FSK (for translators in the USA)
V2 Transmitters support automatic station identification using frequency shift keying (FSK). FSK
sends a user defined ID once every hour using Morse code and shifting the carrier frequency
up by 12.5kHz at 20 words per minute.
FSK ID
If enabled, the FSK ID will be sent once every hour. The required station ID must be entered in
FSK ID (up to 16 characters).
8.1.5 RF Mute on Silence
This selects the time after which the transmitter’s RF output will be muted if the transmitter is
transmitting silence. Options are: off, 1 min, 10 min, 30 min and 1h. The transmitter identifies
silence as a signal that produces a deviation of less than 30 kHz for the time period selected.
The Status box will indicate that the output of the transmitter is muted:
8.1.6 RF Mute (Manual)
This will manually mute the transmitter. The Status box will indicate that the output of the transmitter is muted as shown in the picture above.
8.1.7 Power Scheduler
This feature allows the unit to be configured for transmitting different RF power levels at different times of the day. The unit will normally transmit the signal at the power specified in RF
Settings ⇒ Power. If the power scheduler is disabled, the unit will keep transmitting at this
power level all of the time. If the Power Scheduler is enabled, the unit will switch to the selected scheduled power (Power Scheduler ⇒ Power) when the time matches the Start Time
and will return to normal power when the time matches Finish Time.
This feature is intended to allow users to lower the power of their transmission at night time to
reduce power consumption and avoid increasing the range of the transmission due to the
change in atmospheric conditions. Please adhere to your licensing restrictions on power.
63
Enable
Enables/disables Power Scheduling.
Power
Selects the power that the transmitter will produce during the scheduled interval.
Start Time
Selects the time at which the output power will change from normal power to scheduled
power.
Finish Time
Selects the time at which the output power will change from scheduled power to normal
power.
Current Time
Current time set in the unit. It can be modified to adjust the time in the Real Time Clock.
8.2 Audio Settings
8.2.1 MPX Source
This is the same parameter as described in RF Settings. It has been placed in the Audio settings menu for convenience of access. This selects the source for the exciter. Options are
Internal or External. Internal selects the internal generator, i.e. the output from the internal
audio processor. This option must be selected when the digital or analog inputs are used. External selects the MPX BNC input. This option must be selected when the transmitter is used
with an external audio processor connected to its MPX BNC input.
8.2.2 Audio Input
Selects Digital or Analog as the audio input. These are the XLR connectors in the back panel.
Note that the MPX Source parameter must be set to Internal to use the analog or digital inputs.
64
8.2.3 Processing Preset
BW Broadcast’s range of award winning DSPX audio processors has become known for their
features, performance and value for money. Integrated within all V2 Transmitters is the 4band DSPXmini FM SE. This parameter selects the audio processing preset that the internal audio processor will use. Options are: Bypass, AC, CHR, Tight, Hot, Loud, Smooth, Clean, Bright,
RockNRoll, Low Bass, Urban, Talk, Classic Bright, Classic Bright2. Each processing preset provides a different overall sound. Try and experiment with different presets to find out which
one is more suitable for your program material. Each processing preset is loaded live as the
user scrolls through the menu allowing for easy comparison between them. A dedicated metering screen (Audio Status) indicates the input levels, 4 band automatic gain control and
limiters, along with audio level and MPX level meters. The Bypass preset can be used to bypass the internal processing. This is useful when using an external audio processor connected
to the digital/analog inputs. In this case, an 8dBu signal on the back panel analogue input
(or -18DBFS on AES inputs) should be used to align to the safety clipper thresholds of the internal processor. Make sure Pre-emphasis is off when using the Bypass preset. Another option
for bypassing the internal audio processor is to use the external MPX input. In this case, the
MPX Source parameter must be set to External.
8.2.4 Pre-emphasis
This parameter allows you to select the desired preemphasis characteristic (off, 50us or 75us).
Make sure Pre-emphasis is Off when using an external processor connected to the analog or
digital inputs and select Bypass as the Processing Preset.
8.3 Triggers
V2 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). Triggers are used to control certain parameters on the V2 Transmitter using the relevant pins on
the rear alarms and triggers connector. To fire a trigger, the pin must be pulled low.
Figure 8.1: Alarms and Triggers Port
8.3.1 Enable
Enables/disables the trigger.

8.3.2 Action
Selects what the trigger will do when it is detected. Options are: Frequency Up, Frequency
Down, Power Up, Power Down, RF Mute, Switch to Int MPX, Switch to Ext MPX, Switch to Mono,
Switch to Stereo, Reboot. Frequency Up, Frequency Down, Power Up, Power Down and Reboot will perform the action on falling edges of the signal at the trigger pin. RF Mute acts
based on voltage levels. RF Mute will be engaged for as long as the trigger signal is pulled
low and unmute when the signal is high.
Note that the RFMute pin (Pin 2) mutes the unit unconditionally. (Triggers set to RFMute will
not be able to unmute the unit if this pin is connected to ground).
8.3.3 Send e-mail
Selects if an e-mail will be sent when the trigger is fired. Make sure that the unit is connected
to the network and that E-mails have been set up correctly System ⇒ E-Mail to use this feature.
8.3.4 (ON) Message
Sets the message that will be sent when the Trigger changes to ON. This parameter accepts
text up to 300 characters.
Sample e-mail:
”Trigger 1 transitioned to ON.
Equipment: TX-V2, Serial Number #8790

8.4 Alarms
Alarms on the V2 Transmitter are used to indicate that
a failure condition is met. They can be set to trigger
on Modulation level, Forward power, Reverse power
and PLL lock fail. Upon triggering they will toggle the
relevant pin on the rear alarms and trigger connector. They will also write a notification to the RS232,
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 Analogue outputs (for reporting system parameters as analogue
voltages). When used as alarms (open-collector outputs), 10 kOhm external pull-up resistors to 12 V should
be placed on each pin to be able observe voltage
changes in the alarm pins.
Figure 8.2: Alarms and Triggers Port
8.4.1 Type
Alarms can be configured as either alarms (open collector pins that will show ’0’ volts or open
collector depending on the result of the condition tested); or as analogue outputs, which will
report a parameter as an analogue voltage. The parameter Type allows this selection by providing the options Alarm and Analogue Out.
Alarms pins as Alarms
A Type
When the alarm Type is set to be Alarm, the system will look at the specified failure condition in the Source parameter and trigger the alarm if the condition has been present
for longer than the specified On Delay time or release the alarm if the condition has not
been present for longer than the specified Off Delay time.
B Source
Selects the failure condition that alarm will watch for. Options are: Mod Level <, Mod
Level >, Fwd Power <, Fwd Power >, Rev Power <, Rev Power > and PLL Lock Fail.
- Mod Level observes conditions in the modulation (or deviation) level of the transmitted
signal.
- Fwd power observes conditions in the Forward power
- Rev power observes conditions in the Reverse power
- PLL Lock Fail observes if the PLL lock has failed and the system cannot tune to the required frequency.
67
C Threshold
Selects the threshold value that will be used to detect the error condition. This doesn’t
apply to the PLL Lock Fail alarm.
D Pin Polarity
Selects whether the alarm output pin is active high or active low. When +ve is selected,
the output will act as a 430 Ohm resistor to ground when the alarm is active and as a 100
KOhm resistor to ground when the alarm is not active and vice-versa if -ve is selected.
E On Delay
Selects how long the failure condition must be present for before the alarm is fired. This
can be set from 2 seconds to 600 seconds.
F Off Delay
Selects how long the failure condition must have stopped for before the alarm is released. This can be set from 2 seconds to 600 seconds.
G Send e-mail
Selects if an e-mail will be sent when the alarm state changes. Ensure that the unit is
connected to the network and that E-mails have been set up correctly System ⇒ EMail to use this feature.
Examples of alarm uses and set-up
Example 1: We would like the system to fire alarm A with normal polarity when the forward
power has dropped below 40.5 watts for longer than 20 seconds. We would like the alarm to
be release if the power rises above 40.5 watts for longer than 10 seconds.
Setup:
1. Navigate to Alarms ⇒ Alarm A
2. Select Type = Alarm
3. Select Source = Fwd Power <
4. Set Fwd Power Threshold to 40.5W
5. Set Pin Polarity to +ve
6. Set On Delay to 20s
7. Set Off Delay to 10s
8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is enabled (consult the relevant section in this manual)
68
Example 2: We would like the system to fire alarm B with inverted polarity when the modulation level has dropped below 30 kHz for longer than 15 seconds and release alarm B when the
modulation level rises above that level for 5 seconds. This is a way of detecting that silence
being transmitted.
Setup:
1. Navigate to Alarms ⇒ Alarm B
2. Select Type = Alarm
3. Select Source = Mod Level <
4. Set Modulation Threshold to 30kHz
5. Set Pin Polarity to -ve
6. Set On Delay to 15s
7. Set Off Delay to 5s
8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is enabled (consult the relevant section in this manual)
Example 3: We would like the system to fire alarm C with normal polarity when the reverse
power increases above 10.35 watts for longer than 20 seconds. We would like the alarm to
be release if the reverse power decreases below 10.35 watts for longer than 10 seconds.
Setup:
1. Navigate to Alarms ⇒ Alarm C
2. Select Type = Alarm
3. Select Source = Rev Power >
4. Set Fwd Power Threshold to 10.35W
5. Set Pin Polarity to +ve
6. Set On Delay to 20s
7. Set Off Delay to 10s
8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is enabled (consult the relevant section in this manual)
69
Alarms pins as Analogue Outputs
When the alarm Type is set to be Analog Out, the alarm pin will report the status parameter
selected in Source as an analogue voltage on the alarms pins. This setup is typically used
to connect the unit to remote control equipment (also known as telemetry interfaces). The
Souce can be set to any of the following parameters: Fwd Power, Rev Power, PA Volts, Aux
Volts, Peak Modulation, PA Temp, RF Mute.
Use the following equation to translate voltage levels into parameter values:
CurrentValue =
VOut ∗ 1.2 ∗ NominalValue
5
(8.1)
Where:
VOut is the voltage on the pin in Volts.
NominalValue is defined in the following table:
Parameter
FWD Power
REV Power
PA Volts
Aux Volts
Peak Mod
PA Temp
*RF Mute
NominalValue
For TX50 = 50Watts
For TX300 = 300 Watts
...
Same as FWD Power
For TX5 = 15 Volts
For TX25 and TX50 = 24 Volts
For TX300 or greater = 48Volts
15 Volts
100 kHz
100°C
* This parameter does not use the above equation.
Its representation is:
If RF Mute = On, VOut = 5 Volts
If RF Mute = Off, VOut = 0 Volts
For example, if the measured Voltage level is 4.166 Volts on a TX50 reporting Forward Power,
the actual current value will be:
Power (watts)= (4.166*1.2*50)/5 = 49.992 Watts (Approx. 50 Watts)

V2 FM Transmitter Troubleshooting
Guide
There is no or low RF output power
• Please ensure that you are using the correct mains voltage as specified in the transmitter’s technical manual.
• On the menu, check that the unit is not set to RF mute or that the alarm ports at the back
are not set to RF mute.
• If the unit has a slide-in power supply, please check that the power supply is pushed in
correctly at the back of the unit.
• Check that the set power on the menu to the desired RF power. (BW Broadcast transmitters are set to minimum output power when they leave the factory. This can be adjusted on the front panel via RF settings ⇒ Power. You may want to increase this parameter to the desired power.
• Check that the Power Scheduler feature is disabled (if not required). Or set-up correctly
if required. Check that the System time is correct. All these settings are contained in the
folder: RF Settings ⇒ Power Scheduler
VSWR fault light is on
• The front panel VSWR fault LED illuminates when there is high reverse RF power from the
antenna. This is usually caused by factors external to the transmitter. In this case, please
check the antenna, cable and connectors, as well as the antenna itself.
I am not able to change any settings on the unit (Passcode)
• This usually means that the front panel screen has been locked with a 4 digit passcode.
The original 4 digit code has to be entered before any settings can be changed. Once
the correct code is inserted, press the middle button on the right hand side to confirm
the passcode.
I have no modulation
• Please check that the correct input source has been selected on the front panel controller Audio Settings ⇒ MPX Source. If you are using the digital or analog inputs (XLR
connectors), this option must be set to Internal. If you are using the external MPX BNC
input, this option must be set to External.
79
Modulation level is too low
• Most professional signal sources will be able to drive BW Broadcast transmitters to full deviation. Some battery-powered or weaker sources, such as PC sound cards, may not be
able to provide enough drive to achieve full modulation in the transmitter. If using the
XLR inputs and the internal audio processor then we advise that you check the meters
screen in the Front Panel (Please press the bottom button on the right until meters screen
appears). Assuming that the transmitter preset is not set to Bypass, then you should be
able to observe movement on the meters labeled ”LIM” and ”AGC”. If you they do not
move, then you should increase the level in your audio source so that they do.
If you are not able to increase your audio level from your external audio source you can
increase it by adjusting the level pot located on the left hand side of the 2 BNCs on the
rear panel.
I am using the MPX input and have strange sound issues
• Ensure that Audio Settings ⇒ MPX Source is set to External.
• Leaving it switched to Internal will feed the internal stereo generator audio into the exciter. This will result in distortion and interference with the signal you are feeding from
your external composite source connected to the MPX input of the transmitter.
Transmitter occasionally changes RF power
• Please check tat the Power Scheduler feature is not enabled (RF Settings ⇒ Power
Scheduler). If this feature is required, ensure it is correctly set-up and the time in the system is correct. Please refer to Operation Guide ⇒ RF Settings ⇒ Power Scheduler on
this manual to properly configure this feature.
Temp fault light is on
• Please ensure that the fans are running and not obstructed and the transmitter is in a
well ventilated area.
