2.2  Installing the GUI
>>   Copy all files from the CD to a directory on the control computer.
>>   Execute the /T8318_EP001_9/Installer/Setup.exe  file.  You should see the following screen.
>>   Click install.
>>   The program uses Microsoft.net Framework. This software will be installed if the
      setup does not detect it.
　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　
2.3  Starting the GUI
>>   Go the Start Menu
>>   Select the All Programs Menu
>>   Select ' BUC_EP001_10'  and
     You can see the following screen.
>>   Select COM Port Number  and
>>   Click the ' OPEN '
　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　
>>    If the GUI has established connection thru Serial to the BUC,
      You can see the following control screen.
　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　
2.4  Operating the GUI
>>   General
Send Command Box The GUI shows the transmitted command bytes  to BUC in Hexadecimal format.
Received Response 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 will query the BUC and display the current status.
BUC Address BUC Address is a fixed value for the moment.
Output Power Showing the transmitting RF power level in dBm 
Temperature Showing the internal sensor temperature in ℃ 
Temperature 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 the check sum error of BUC reception, the BUC reply "1" 
Mute Control The mute control state (ON or OFF) is displayed. 
In the case of 'ON' the BUC reply "0".
Power Class Showing the BUC's power class. (See 3.4  BUC Power Class)
Firmware Ver. Showing the BUC's firmware version.
　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　
>>   Set Mute Control
Click a check box(On/Off), when you change into a mute control state to ON or OFF.  (GUI sends mute control command To BUC.)
When you click the command button, GUI sends the same command to BUC again.
>>   Set Gain Control 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 15.5dB and 0.5dB steps.
>>   Get Gain Control Attenuator
The GUI will query the current Gain Control Attenuator value.
Click the command button, and GUI replies the value.
>>   Request Status Option
Check a check box ( Repeat ) in executing the command repeatedly. 
Then, GUI shows a text box for the setup of a time interval. 
Input the suitable numerical value for the text box in the unit of 'second'. 
Then, click the command button and start logging.
GUI creates a log file ( Status.csv ) to the desktop of your control PC.
Since the log file is created in append mode, data is not overwritten even if it resumes logging. 
　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　
3. PROGRAMMING INFORMATION
This section describes:
>>    Detailed description about communication specification.
3.1    Communication Protocol
3.1.1   COM port setting
Specify the serial port property for RS232 as follows.
Baud rate 9600
Data bit 8
Parity none
Stop bit 1
Flow control none
3.1.2    Procedure
A communicative start is always a control computer and a BUC always waits for the command. 
If the command from the controller is received, the BUC will start requested processing. 
The BUC will reply to the controller, after processing is completed. 
3.1.3    Frame format
Transmission and reception are the same frame structure.
Byte# Contents of the byte description 　 　 　 　 　
1 Address of BUC ・Fixed 0x01**
2 Command / Data byte 1 ・2nd byte : Command byte in Transition frame.
The first Data byte in Reception frame.
3 Data byte 2
・Command byte is assigned to each function.
4 Data byte 3 ・Data bytes １−５ are defined by each function.
