WARNING Changing the above parameters may adversely affect
the ability of the device to operate for extended periods under low
solar radiation conditions when used with addVANTAGE 3.x. Even
if you change them, addVANTAGE will not display the charts
accordingly: the current addVANTAGE version supports only 15-
minute data slots. Changing the storage parameter to lower than
60 or higher than 1500 will lead to a total data loss in
addVANTAGE 3.x. This warning does not apply to usage with
addVANTAGE 4.x Lite software.
COMMAND SET FREQ freq step
DESCRIPTION Sets the unit’s operating frequency.
PARAMETERS freq is the frequency and step is the channel spacing (both
expressed in Herz).
RETURNS Nothing.
REMARKS Convert values to Herz before issuing the command.
EXAMPLE To change the frequency to 467.1125 MHz with a channel spacing
of 12.5 kHz:
SET FREQ 467112500 12500
CAUTION Do not change the frequency of your device without
reason: apart from the fact it may not communicate in the network
anymore, you may also violate the applicable radiocommunica-
tions laws in your country. Depending on the destination country,
some models may also return an error message.
COMMAND SET RSSI value
DESCRIPTION Sets the Relative Signal Strength Indicator threshold.
PARAMETERS value is the RSSI setting.
RETURNS Nothing.
REMARKS The factory default is set to 58 units. The RSSI threshold is used to
detect if any radio activity is on the channel. The value set must be
approximately 30% higher than the actual measured value when no
signal is present on the channel. To measure the actual value, use
the command RSSI (see "Querying the actual configuration
parameters").
