A-2-2 Connect the serial setup terminal
On the X0 RJ45 connector is an optional serial communications port with RS232/
485 protocol. Depending to the terminal used to setup the system, the user must:
•Set the X0 port as RS232;
• Provide the proper connection cable;
• Set the correct communications parameters;
• Run the communications program.
RS232 Serial Communications Connection
To connect a VT100 terminal or a PC with Hyper Terminal program, connect the
X0 connector to an RS232 cable with the following characteristics:
Setting the
comm.s
parameters
At this point the HyperTerminal must be configured in order to communicate with
the correct COM Serial port. When the Personal Computer has no serial port, the
connection can be done through a USB-Serial adapter; in this case the number of
the COM port linked to the USB connector can be found in:
Start\ControlPanel\System\Hardware\Peripherals\Ports (COM and LPT)
Using the COM port number open a new session of HyperTerminal and set the
default communication parameters in order to match those of the service port:
During the configuration session it will be possible to change the baudrate, stop bit
and parity (see
“Serial Setup Menu” on page 12 for details). When the
communications parameters of the system are changed, the communications
parameters of the terminal (or PC) must be changed accordingly. The setup is
performed by browsing the menus sent to the VT100 terminal or to the terminal
emulation program (HyperTerminal) by the system.
