4.6.3 LOCALLY ACCESSING THE RFL 9660
If you are at the substation, you can access the RFL 9660 locally by connecting a terminal to the LOCAL
connector on the RFL 9660's front panel. This terminal can be a dumb RS-232 terminal, a PC, or a laptop
computer with an RS-232 port running a terminal emulation program.
To access the RFL 9660 locally, use the following procedure:
1.
Connect the local terminal to the RFL 9660's LOCAL port.
For this connection, you will need a cable with a 9-pin D-subminiature (DE-9) male
connector at one end. This cable will either have a 9-pin D-subminiature (DE-9) or a 25-
pin D-subminiature (DB-25) connector, depending on what kind of mating connector
you have on your PC or terminal. A suitable ready-made cable can be purchased locally
at any electronics or computer store, or you can make your own cable using Figure 3-2
in Section 3 as a guide.
Most dumb terminals have a single RS-232 connector, and this is where you would
connect the cable. On many PC's or laptops, the cable will be connected to the COM1
port. If your PC has a mouse connected to COM1, connect the cable to the COM2 port.
Refer to the manual supplied with your PC or terminal for more information.
2.
Set the local terminal set to match the RFL 9660's local port configurations setting (2400 baud,
8 data bits, 1 stop bit, no parity).
Many dumb terminals have DIP switches you can use to set the configuration; refer to
your terminal manual for more information. If you are using a PC with a terminal
emulation program, set the configuration within the program; refer to the
documentation supplied with the terminal emulation program for more information.
3.
Make sure the RFL 9660 is turned on and ready for access.
If the RFL 9660 is turned on and no other user is accessing it, the STATUS display will
read "PL." This means the RFL 9660 is idle and polling all its ports, looking for a
connect request. (Refer to Section 3 for more information about turning on the
RFL
9660.
4. Press
the
[ENTER]
key on your keyboard a few times.
If the super-user has enabled password protection, go to step 5. If passwords are not
being used, go to step 7.
5.
The following prompt will appear on your display:
Please
enter
password
When you see this prompt, enter the password on your keyboard.
For each letter of the password you enter, the RFL 9660 will echo back an asterisk (*).
NOTE
Passwords are case-sensitive.
If the super-user stored the password as all CAPITALS, you must
enter it that way. Otherwise, the RFL 9660 will reject it.
