CHAPTER 4

Performing Advanced Functions

 

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").
