1.1.1. System assembly 

z  Use a 50 Ohm coaxial cable to connect the U.FL connector on the reader board   
z  Use DC power supply or a stabilized laboratory power supply with current rating 

of at least 1000 mA at output voltage with a voltage setting of 5 Vdc for supply 
the JIG board. Use RS-232 cable to connect PC and the JIG board. 

1.1.2. Stand-alone operation 

When power is supplied to the board, Reader automatically starts stand-alone 
operation. In this operation Reader continuously searches transponders in 
antenna field. 

1.1.3. Operation of the board PC based with graphic user interface control 

You have to set the RS-232 port properties first. In the Windows Start menu, 
open Control Panel/System/Hardware/Device Manager/Ports. Double click on 
the COM port and open the 'Port Settings' tab, choose 115200 bits/s, 8 Data bits, 
No parity, 1 Stop bit, No Flow control. In case the COM port is assigned a very 
high number (above 6) use Advanced options to assign it a lower number. 

Once this is complete you can connect reader board to a PC with the RS-232 
cable and start GUI program. The GUI should automatically detect the COM 
port number that the board is attached to. If it is different from the one that you 
have manually selected, please select the COM port that you used in the settings.
