Other radio related Effect and description of command
SL@R? Display field strength of the last received message (the value is an average of
many measurements made during the same reception).
Response ”-xx dBm”, where xx is a decimal value of the field strength and it is
between –80 dBm and –118 dBm. Value available 7s after reception.
SATELLINE-3AS Epic returns the stronger value of two receivers.
SL@P=xxxxx Set the RF output power, where xxxxx is the decimal value of the intended
power in milliwatts. If the given value does not correspond to one of the
programmed power levels, the output power is set to the nearest possible
value.
SL@P? Requests the RF output power.
Response ”xxxxx mW”, where xxxxx is a decimal value the output power of the
transmitter.
SL@T=-xxx Set the minimum power level of the signal to be received (="Signal Treshold
level), where xxx is a decimal value of the new intended level in dBm.
