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.
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.
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.
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 4- band DSPXmini FM SE. This parameter selects the audio processing preset that the internal au- dio processor will use.

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 connec- tor.
Page 68
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.
Page 69
Example 2: We would like the system to fire alarm B with inverted polarity when the modula- tion 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.
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.
