8.PC COMMUNICATION METHOD
(a) Power meter is compatible with RS232
communication.
(b) The basic transmission protocol is as follows :
Transmission protocols can be conrmed from a
hyper terminal.
(1) Communication port : connect to a created port
in the case of a serial communication port.
(2) Transmission speed : 9600
(3) Parity : none
(4) Stop bit :1
(5) Flow control : none
(6) Normal mode :
When the english capital letter "C" is transmitted
from a PC is pressed, data will be consecutively
received and "COMM" will be displayed on the
product's screen. When the english capital letter
"P" is transmitted, the communication will be
cancelled.
(7) Log mode :
When the english capital letter "L" is transmitted
from a PC is pressed, data will be consecutively
received and "COMM" will be displayed on the
product's screen. When the english capital letter
"P" is transmitted, the communication will be
