IT6100B  configure  with  three  type  of  communication  interface  RS232,  USB  and 
GPIB for user adopting any of it flexible. 

5.1 RS232 interface 

There  is  a  DB9  connector  at  the  rear  of  the  power  supply,  when  connect  to 
computer,  you  need  to  connect  a  cable  with  COM  port  on  both  side;  active

RS-232 data format 

RS-232 data is a 10-bit word which has a start bit and a stop bit. The start bit and 

stop bit can not be edited. However, you can select the parity items with
