Chapter 5. COMMUNICATION
5.1 INSTALLATION
The RS-232 port of PT630 can communicate with the serial port of a host computer. There are
two ways to carry out communication sessions:
(1) LOCAL : Directly connect to the serial port of your computer system.
(2) REMOTE : Connected by two attached modems and one telephone line.
5.1.1 LOCAL CONNECTION:
In the Local connection method, the PT630 is directly connected by a null modem cable to the
serial port of the host computer. This is the way to
download
or
upload
files
from/
to
your
PT630. Note that the communication parameters must be matched on your PT630 and host
computer, otherwise, the communication will fail.
