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"). |
