TX V2 FM Broadcast Transmitter
Introduction
Introduction
The BW Broadcast 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 (not present on all
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 without
having to refer to the technical manual
Every 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 V2 Transmitter.

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&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 50Ω antenna of the correct power handling capability.

Remote Control
Telnet
For text based access via a local network or the internet, Telnet can be used to connect to the unit.
On the unit, navigate to
System → Telnet
Ensure enable is set to enabled, and note the port number (23 by default).
Connect to a unit using a standard telnet client.
The IP address of the unit can be found either in the System → Ethernet menu or on the Config meters screen.
Once connected, the unit can be controlled using the same commands as RS232/Serial.
Telnet is password protected, but as with most terminal systems, no indication is given that characters have been
accepted. Type the user name and password (default admin and pass) and press enter to log on to the unit.
HTTP
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.
Email Alerts
V2 Transmitters allow the sending of emails to provide notification of an alarm or external trigger being activated.
The transmitter can either send emails via a user defined SMTP server or an SMTP server hosted by BW
Broadcast.
To send email, the V2 Transmitter needs to be configured with your SMTP server details:
1. Navigate to System → Email.
2.
a. If using your own SMTP server, set the Host and Port to that of the network SMTP server. Set
the From, Username and Password fields to that of the email account to be used as the
sender. Set the recipient or recipients for the emails. If sending to multiple email addresses,
separate with a comma. If the SMTP server requires no authentication the Username and
Password fields must be left blank. The user can set the maximum number of emails sent per
day, and see the total number of emails sent so far today. If the limit is reached, the V2
Transmitter will send an email informing the user.
b. If you do not have access to an SMTP server, emails can be sent via a SMTP server hosted
by BW Broadcast. To select this option use
send via→ BW Broadcast
3.
To test the server settings, navigate to
Test → Recipients
and enter the appropriate email address. Select Test and select Yes.
Once the SMTP server settings have been entered the email setting must be activated on the Alarm and Trigger
menus for the V2 Transmitter to send emails on Alarm and Trigger events.
For alarms:
Alarms → Alarm [A-C] → Send e-mail Yes.
For triggers:
Triggers → Trigger [1-4] → Send e-mail Yes.

To perform a software upgrade:
1. Log into the V2 Transmitter using the HTTP web remote.
2. Click System settings on the sidebar
3. Click Upload Firmware
4. Click Browse and navigate to the upgrade .bin file on the PC
5. Click Open
6. Click Upload
Alarms and 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.
Alarms
Alarms on the V2 Transmitter give an indication when a certain 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 and
will also write to the system log.
1. Ground
2. RF Mute
3. Alarm C
4. Trigger 2
5. Trigger 4
6. Alarm A
7. Alarm B
8. Trigger 1
9. Trigger 3
To set an alarm:
1.
2.
3.
4.
Navigate to Alarms in the Main Menu
Select the appropriate alarm you wish to set (A-C)
Set Type to “Alarm”
Set the parameters for the alarm
a. Select the parameter you wish to trigger the alarm on, the available parameters are Modulation
level, Forward power, Reverse power and PLL lock fail.
b. If Modulation level, Forward power or Reverse power are selected, set the threshold value for
the alarm to trigger.
c. Set the pin polarity which selects whether the output pin on the rear connector is active high or
active low.
d. Set the on/off delays which set how long the error condition must occur for before an alarm is
triggered and how long the error condition must have stopped for before an alarm is untriggered. Setting a short on delay combined with a long off delay will cause the alarm to trigger
and stay high if there is an intermittent fault.
e. Select if the unit will send an email when the alarm is triggered. Information on email settings
can be found in the Email section of the System menu.
Alarms as Analog Outputs
Alarms can be configured to report status parameters as analog voltages on the alarms pins. This setup is
typically used to connect the unit to remote control equipment (also known as telemetry interfaces).
To set an alarm as analog output:
1.
2.
3.
4.
Navigate to Alarms in the Main Menu
Select the appropriate alarm you wish to set (A-C)
Set Type to “Analog Out”
In source, select the parameter that you wish to report as an analog voltage on the alarm pin
19
TX V2 FM Broadcast Transmitter
Alarms and Triggers
Use the following equation to translate voltage levels into parameter values:
CurrentValue =
∗ 1.2 ∗ NominalValue
Where:
“VOut” is the voltage on the pin in Volts
“NominalValue” is defined in the following table:
Parameter
NominalValue
FWD Power
For TX50 = 50 Watts
For TX150 = 150 Watts
Same as FWD Power
For TX5 = 15 Volts
For TX25 = 24 Volts
For TX50 = 24 Volts
For TX150 or greater = 48 Volts
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
REV Power
PA Volts
Aux Volts
Peak Mod
PA Temp
*RF Mute
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
= 49.992 Watts Aprox. 50 Watts

Logging
Triggers
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 is pulled low. If multiple triggers are fired the lowest number gets
priority i.e. 1 = highest priority, 4 = lowest priority.
1.
2.
3.
Navigate to Triggers in the Main Menu
Select the appropriate trigger you wish to set (1-4)
Set the parameters for the alarm
a. Enable the trigger in the menu
b. Set the parameter you wish to change using the trigger
c. Select if an email is sent when the trigger is fired
d. Set the message to be sent in the email when the trigger is fired.
Pin 2 of the alarms and triggers connector is hard wired to the RF Mute on the transmitter. When this pin is pulled
low, the V2 Transmitter will mute the RF output.
Logging
V2 Transmitters have three methods of logging, regardless of the log location, the format is the same.
V2 Transmitters will output a list of important parameter all meter settings and alarm & trigger statuses 2 minutes
after a parameter change and then at hourly intervals. These can be either received via RS232, UDP or saved to
a file on the device. Each method can be enabled or disabled in the system → Log menu.
To access the logging via RS232, simply connect the device using the instructions for the RS232 remote and
ensure RS232 logging is enabled in
System → Log → RS232 Enabled
Similarly for file logging
System → Log → File Enabled
To access via UDP, again ensure that UDP logging is enabled and all settings are correct in
System → Log → UDP
To access the file log, first the user must log into the device using the http remote, and then navigate to http://[IP
address of TX V2]/TX V2.log (e.g. http://192.168.0.131/TX V2.log). A new log file is created every 24 hours and
all files are kept for 31 days. To access a previous days log file, use http://[IP address of TX V2]/TX V2.log.[n]
where [n] is the number of days since the log file, e.g.
http://192.168.0.131/TX V2.log.1 is yesterday
http://192.168.0.131/TX V2.log.2 is two days ago
http://192.168.0.131/TX V2.log.7 is one week ago
