Section 3. SWITCH AND PORT CONFIGURATION
3.1 INTRODUCTION
The procedures in this section will tell you how to configure the RFL 9660 and its ports to match your terminal
and your substation equipment. These procedures can be used when first installing the RFL 9660, or any time
the RFL 9660 configuration settings need to be changed or verified.
NOTE
When using the procedures in this section to change the RFL 9660's configuration settings, always
keep a record of the changes you made. This record will be useful if it becomes necessary to re-
program the RFL 9660.
3.2 CONTROLS AND INDICATORS
You will be using many of the RFL 9660's controls and indicators while setting its switch and port configuration.
These controls and indicators are shown in Figure 3-1 and described in Table 3-1.
3.3 MAKING CONNECTIONS TO THE LOCAL TERMINAL
To configure the RFL 9660, you will have to connect 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. For the rest of this section, the PC or terminal connected to the LOCAL connector
will be called the "local terminal."
To connect the local terminal to the RFL 9660's local port, you will need a cable with a 9-pin D-subminiature
(DB-9) male connector at one end. The other end of this cable will either have a 9-pin D-subminiature (DB-9) or
a 25-pin D-subminiature (DB-25) connector, depending on what 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 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.
Once the local terminal is connected to the LOCAL connector, it can be set to match the factory default settings
for the RFL 9660's local port configuration (9600 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. If you would rather change
the local port's configuration to match that of your PC or terminal, refer to Section 8 for information on how to set
SET-UP switch S1 on the CPU module.
