In case of RS232 model  it should be set to 0x01. (default value)
Using different address can make multi drop communications like RS422 type.
Send Command Box The GUI shows the transmitted command bytes to BUC in hexadecimal format.
Received Respnse Box The GUI shows the received data bytes from BUC in hexadecimal format.
In the case of the check sum error of PC reception, GUI adds a 'False' 
to the received data. 
>>   Request Status
The GUI sends a query  by this command and it displays the current fundamental status.
Output Power Showing the transmitting RF power level in dBm.
Temperature Showing the internal sensor temperature in ℃.
Temp. Alarm In the case of exceeding a temperature limit the BUC reply "1".
LO Status In the case of unlocked state the BUC reply "1".
Check Sum When an check-sum error has occurred in BUC reception,
it notifies you only when it receives a Request Status command next.
Mute Control The mute control state (ON or OFF) is displayed. 
In the case of 'ON' the BUC reply "0".

After Transmit-On command, if there is not an error BUC sets Transmit-On.
>>   Get Attenuator
The GUI will query the current Gain Control Attenuator value.
Click the command button, and GUI replys the value.
>>   Set Attenuator
Fill the suitable numerical value for a text box in the unit of 'dB'. 
Then, click the command button.
The Data range is from 0dB to 31.5dB with 0.5dB steps.
>>   Set Carrier Frequency
This Model is not applicable.

>>   Get PS Status
The GUI sends a query  by this command and it displays the current PS status by 'Normal' or 'Fail', and voltage data in volt unit.
>>   Get Temperature status
This Model is not applicable.
>>   Get Power Monitor status
This Model is not applicable.
>>   Get Band Select
This Model is not applicable.
>>   Set Band Select
