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 =
V
Out
∗
1.2
∗
NominalValue
5
(8.1)
Where:
VOut is the voltage on the pin in Volts.
NominalValue is defined in the following table:
Parameter NominalValue
FWD Power
For TX50 = 50Watts
For TX300 = 300 Watts
...
REV Power Same as FWD Power
PA Volts
For TX5 = 15 Volts
For TX25 and TX50 = 24 Volts
For TX300 or greater = 48Volts
Aux Volts 15 Volts
Peak Mod 100 kHz
PA Temp 100°C
*RF Mute
* 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)
