Open a communications software to serial ports, we recommended to use RealTerm free download on 
the following link: 

http://sourceforge.net/projects/realterm/files/Realterm/

 

All the examples cited in this manual have been performed with Realterm. 

Many  communication  programs  are  available  for  serial  ports  suitable  for  this  purpose,  however,  in 
order  to  exclude  errors  introduced  by  them  and  to  get  adequate  support  from  the  vendor,  it  is 
recommended to perform the experiments described below using Realterm, at least until it reaches an 
appropriate level of confidence with the XTR-8LR100 form or XTR-8LR10. 
 

4.

 

Start the program and set the communication parameters as shown below. 
Communication speed 115200 bps, the START bit, 8 data bits, and a STOP bit, no parity. Select the 
port  number  that  has  been  associated  with  XTR-8LR-USB,  in  this  case  the  port  associated  with  the 
XTR-8LR-USB  is the "Port 109". 
After each change of the working parameters of the serial port, remember to press the button "Change" 
to  Realterm,  the  set  values  are  visible  at any  time  in the small  box at  the  bottom  right  of  the  screen 
Realterm.
