SAFETY SUMMARY

The following safety precautions must be observed at all times during operation, service, and
repair of this equipment. Failure to comply with these precautions, or with specific warnings
elsewhere in this manual, violates safety standards of design, manufacture, and intended use
of this product. RFL Electronics Inc. assumes no liability for failure to comply with these
requirements.

GROUND THE CHASSIS

The chassis must be grounded to reduce shock
hazard and allow the equipment to perform
properly. Equipment supplied with three-wire ac
power cables must be plugged into an approved
three-contact electric outlet. All other equipment
is provided with a rear-panel ground terminal,
which must be connected to a proper electrical
ground by suitable cabling. Refer to the wiring
diagram for the chassis or cabinet for the location
of the ground terminal.

DO NOT OPERATE IN AN
EXPLOSIVE ATMOSPHERE
OR IN WET OR DAMP AREAS

Do not operate the product in the presence of
flammable gases or fumes, or in any area that is
wet or damp. Operating any electrical equipment
under these conditions can result in a definite
safety hazard.

KEEP AWAY FROM
LIVE CIRCUITS

Operating personnel should never remove
covers. Component replacement and internal
adjustments must be done by qualified service
personnel. Before attempting any work inside the
product, disconnect it from the power source and
discharge the circuit by temporarily grounding it.
This will remove any dangerous voltages that
may still be present after power is

removed.

DO NOT SUBSTITUTE PARTS
OR MODIFY EQUIPMENT

Because of the danger of introducing additional
hazards, do not install substitute parts or make
unauthorized modifications to the equipment. The
product may be returned to RFL for service and
repair, to ensure that all safety features are
maintained.

READ THE MANUAL

Operators should read this manual before
attempting to use the equipment, to learn how to
use it properly and safely. Service personnel must
be properly trained and have the proper tools and
equipment before attempting to make adjustments
or repairs.

Service personnel must recognize that whenever
work is being done on the product, there is a
potential electrical shock hazard and appropriate
protection measures must be taken. Electrical
shock can result in serious injury, because it can
cause unconsciousness, cardiac arrest, and brain
damage.

!

Throughout this manual, warnings appear before
procedures that are potentially dangerous, and
cautions appear before procedures that may result
in equipment damage if not performed properly.
The instructions contained in these warnings and
cautions must be followed exactly.

"One Phone Line Connects

All

Substation Devices"

The RFL 9660 Digital Switch provides a convenient way to connect intelligent relays, smart meters, sequence­of-event recorders, digital fault recorders (DFRs), or similar devices to a central intelligent digital switch.Through
the use of third-party software packages, the RFL 9660 is able to communicate with Intelligent Electrical
Devices

(IED's). Once connected, the user can access and interrogate up to 32 individually
programmable RS-232 ports. This allows maintenance personnel to instantly access substations from their
desks, without having to make a field trip.

Only a single phone line is required to connect to the RFL 9660; this reduces the number of phone lines
required for polling substation equipment.

By

replacing the internal modem with a direct digital interface, the

RFL 9660 can also be connected to an existing substation digital network.

Diaital Switch

Regular telephone line sharing switches require a
separate modem at each device. For example, an
installation with eight devices would require eight modems.
To eliminate expensive modem costs, the RFL 9660 has
been designed to contain its own integrated modem. It's
all that's needed to interface all your recorders, relays,
solid-state meters, or similar equipment.

The RFL 9660 eliminates:

Separate phone lines
Individual telephone modems
Expensive modem installation and
maintenance costs.

In order to prevent unauthorized access, the RFL 9660
features three different levels of security and an
access alarm output. In the first level of security, each
device port can be protected with a password. The

second level adds a log-on password that must be used
when the switch is first called. The third level has a
callback feature that causes the RFL 9660 to call the
user back at a preset telephone location before
access is allowed.

Any installation where ambient noise levels

Any installation where it is difficult to run

Section 2. INSTALLATION

WARNING

THE RFL 9660 MUST BE PROPERLY GROUNDED AS DESCRIBED IN THIS SECTION BEFORE
ATTEMPTING TO PLACE THE SWITCH IN SERVICE. IMPROPER GROUNDING MAY RESULT IN
SYSTEM MALFUNCTIONS, EQUIPMENT DAMAGE, OR ELECTRICAL SHOCK.

CAUTION

During normal operation, the switching of relay contacts can produce voltage spikes. These spikes
can travel down the relay output leads and induce currents in other leads. These induced currents can
result in corrupted data. To reduce this possibility, use shielded cable for all connections to the
RFL 9660's PORT connectors. Shielded cable should also be used for the connections between the
RFL 9660 and the local DTE when the direct digital interface is used. As an added precaution, do not
bundle data, relay output, and power leads into the same harness - keep them as far apart as
possible.

Before attempting to make power connections, make sure the power switch on the RFL 9125 power
supply module is in the off (down) position. Also, make sure the power supply can operate at the
available station battery voltage. This can be determined by checking the numbers next to the model
designator on the module handle. If you connect the wrong voltage to the power supply, component
damage will result.

2.1 INTRODUCTION

This section contains installation instructions for the RFL 9660, including unpacking, mounting, and wiring.
Figure 2-7 at the end of this section summarizes the information in this section.

2.2 UNPACKING

Each RFL 9660 is packed in its own shipping carton:

1. Open each carton carefully to make sure the RFL 9660 is not damaged.

2. After removing the RFL 9660 from the carton, carefully examine all packing material to make sure no
items of value are discarded.

3. Carefully remove any packing materials inserted into the RFL 9660 to hold circuit board modules in
place during transit.

4. Make sure all front-panel modules are fully seated in the chassis. The quarter-turn fasteners securing
each module in place should all be in the locked position (screwdriver slots vertical).

If you notice any signs of shipping damage, immediately notify RFL Customer Service at the phone number
listed at the bottom of this page. Save all the packing material and the shipping carton, in case a damage claim
needs to be filed with the shipping company that delivered the unit.

2.3 MOUNTING

After unpacking, the RFL 9660 must be securely mounted. The RFL 9660 chassis has two mounting ears (one
on each side). Hole sizes and spacings conform with EIA standards, so the RFL 9660 can be mounted in any
standard 19-inch rack or cabinet. Figure 2-2 provides complete mounting dimensions.

2.4 VENTILATION

The specified operating temperature range for RFL 9660 equipment is -30oC to +65oC (-22oF to +149oF).
Operation at higher temperatures may affect system reliability and performance. Systems installed in enclosed
cabinets should be ventilated to keep the temperature inside the cabinet within limits.

2.5 CONNECTIONS

Electrical connections are made to the RFL 9660 through the terminal blocks and connectors on its rear-panel
I/O modules. (See Figure 2-1.) The following paragraphs provide basic descriptions of all the connections that
must be made.

Figure 2-1. Rear view of typical RFL 9660 Digital Switch

2.5.1 MAKING CONNECTIONS TO TERMINAL BLOCKS

The terminal blocks on the RFL 9660's rear-panel I/O modules are conventional screw-type barrier blocks.
Depending on local practice, you can either strip the wires you connect to them, or terminate the wires in spade
lugs.

To connect wires to the terminal block on the PWR/ALARM I/O (Part Number 104400) or AC/ALARM I/O (Part
Number 104400-1), you will have to remove the protective cover from the terminal block by pulling it out of the
standoffs holding it in place. After all connections have been made to the terminal block, reinstall the protective
cover by lining up its mounting holes with the standoffs on the I/O module. Once the holes and standoffs are
lined up, push down on the protective cover to secure it in place.

2.5.2 ALARM, REMOTE DISCONNECT, GROUND, AND POWER CONNECTIONS

All alarm, remote disconnect, ground, and power connections are made to the RFL 9660 through terminal block
TB1 on the PWR/ALARM I/O module. Figure 2-3 shows the connections that must be made on dc-powered
units; Figure 2-4 shows the connections for ac-powered units.

NOTES:

1. The ALARM relay changes state when the RFL 9660 detects a loss of power,a CPU failure, or a fiber optic failure.

2. The ACCESS relay changes state whenever the RFL 9660 grants a user access to the switch.

3. When the remote disconnect input is active, the RFL 9660's modem will hang up and de-select the active port.
Input voltages from 42 Vdc to 142 Vdc can be accepted.

4. The grounding wire should be kept as short and straight as possible, to keep its resistance and inductance
to a minimum.

2.5.3 TELEPHONE CONNECTIONS

The RFL 9660 is equipped with a two-wire I/O module. The substation phone will not be disabled once the
RFL 9660 is connected to the telephone line; you will still be able to make outgoing calls.

The RFL 9660's modem will automatically answer after four rings (two rings on "double-ring" telephone
systems). This number of rings is programmable up to 255; consult the factory if you wish to make a change.

2.5.3.1 Two-Wire Connections

RFL 9660 units equipped with VF 2W I/O Two-Wire Telephone Interface Modules (Part Number 104860-1) have
two RJ-11 telephone jacks on the rear. Connect the incoming telephone line to the LINE jack. Connect a
standard telephone deskset to the PHONE jack. (See Figure 2-5.) Telephone line cords are not provided with
the RFL 9660. They can be purchased locally, or obtained from your local telephone company.

2.5.4 RS-232 PORT CONNECTIONS

If your RFL 9660 is equipped with one or more RS-232 I/O modules (Part Number 104420), there will be a
series of 9-pin D-subminiature (DB-9) male DCE connectors on the rear of the RFL 9660. Each of these
connectors provides all connections for one RS-232 port. Port assignments are shown in Table 12-1 in
Section 12. Space is also provided in the table for you to write in the name or description of the device
connected to each port, along with its communications characteristics. You will need this information when you
use the procedures in Section 3 to set the switch and port configuration.

Terminal assignments for the device port connectors are shown in Figure 2-6. You do not have to make
connections to all pins. Wiring will depend on the specific device being connected to the port. Refer to
Section 16 for application notes for the specific device you are wiring, or refer to the manual supplied with the
device.

2.5.5 CONNECTIONS TO DIRECT DIGITAL INTERFACE

If your RFL 9660 is equipped with a direct digital interface I/O module (Part Number 104455) instead of a
modem module and telephone interface module, there will be a 25-pin D-subminiature connector (DB-25 male)
on the rear panel. A cable must be connected between this connector and the local DTE. The DTE can be either
an external modem or a communications network multiplexer. Pin assignments for this connector are shown in
Figure 2-7.

NOTE

Unless specified at time of order, the direct digital interface port is set for 2400 baud, eight data bits,
one stop bit, and no parity. If the DTE or modem you are connecting to requires a different setting, go
to Section 8 and reset DIP switch S3 on the CPU module before attempting to use the RFL 9660.

2.5.7 CONNECTIONS TO FIBER OPTIC MASTER AND REMOTES

If your RFL 9660 is equipped with a fiber optic master I/O module (Part Number 104430), you will have to
connect fiber optic cables between it and the fiber optic remotes. This forms the fiber optic ring, as shown in
Figure 2-9. Each fiber optic cable in the ring can be as long as 2000 meters (1.24 miles).

Figure 2-9. Fiber optic connections between master and remotes in fiber optic ring

At each fiber optic remote in the ring, power connections are made and cables are connected between the fiber
optic remotes and the RS-232 devices that are being connected to the fiber optic ring. To make these
connections, proceed as follows:

1. At the RFL 9660, connect the outgoing fiber optic cable to the TX fiber optic connector on the fiber
optic master. Connect the incoming fiber optic cable to the RX fiber optic connector.

2. Make the following connections and DIP switch settings at each fiber optic remote:
a. Connect the outgoing fiber optic cable to the TX fiber optic connector on the back of the fiber

optic remote. Connect the incoming fiber optic cable to the RX fiber optic connector.

RFL 9660 RFL Electronics Inc.

April 24, 2007 2-11 [phone]

b. Connect station battery positive to terminal TB1-4 on the terminal block. Connect station battery
negative to terminal TB1-3. Connect chassis common to the center terminal on TB1 (the one
with the ground symbol beneath it).

If you have up to three fiber optic remotes at the same site, you can use the setup

shown in Figure 2-10 to drive two 9-volt remotes from the power supply in one

48-volt or 125-volt remote. To avoid large voltage drops in the connecting wires, this
method should only be used with fiber optic remotes that are near each other.
Long wire runs would drop the supply voltage to a level that is too low for reliable
remote operation.

Figure 2-10. Power connections between three fiber optic remotes at the same site

RFL 9660 RFL Electronics Inc.

April 24, 2007 2-12 [phone]

c. Connect the RS-232 device to the 9-pin D-subminiature (DE-9) connector on the back of the
fiber optic remote.

Terminal assignments for the device port connectors are the same as those
shown in Figure 2-6 for the RFL 9660's rear panel PORT connectors.

You do not have to make connections to all pins. Wiring will depend on the
specific device being connected to the port. Refer to Section 16 for application
notes for the specific device you are wiring, or refer to the manual supplied with
the device.

d. Set TX PWR switch S2 for the required optical output power.
S2 has four possible settings, producing four different power levels:

Output S2-1 S2-2

-16 dBm OFF OFF

-13 dBm ON OFF

-11 dBm OFF ON

-10 dBm ON ON
When setting S2, remember that OFF is up, and ON is down.
e. Set ADDRESS switch S1 for remote module's address.

S1 sets up a binary number that represents the port number assigned to the
device. (See Table 2-1 for the proper settings for each of the RFL 9660's 32 port
numbers). When setting S1, remember that OFF is up, and ON is down.

f. Repeat steps 2a through 2e at all other fiber optic remotes.

2.6 SYSTEM EXPANSION

Your RFL 9660 was shipped with the correct number of device I/O modules for the number of device ports you
ordered. Up to four device I/O modules can be installed in the RFL 9660, for a maximum capacity of 32 device
ports.

When installing additional device I/O modules, the following rules apply:

1. The bottom I/O module slot must always be occupied.

2. Additional device I/O modules must be installed from bottom to top; do not skip any I/O module slots.

3. An RFL 9660 may contain both RS-232 and fiber optic device I/O modules. If both types are to be
installed, the RS-232 I/O modules must be at the bottom, with the fiber optic module on the top.

4. If you are adding an RS-232 I/O module to an RFL 9660 that already has a fiber optic I/O module, the
fiber optic I/O module must be moved up one slot and the RS-232 I/O module installed below it. If the
RFL 9660 has already been programmed for the devices connected to the fiber optic loop, it will have
to be re-programmed, since the fiber optic devices have now been moved up eight port numbers. The
address settings on the remote fiber optic modules must also be changed.

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 re­program 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.

3.4 TURNING ON THE RFL 9660

To turn on the RFL 9660, simply place the rocker switch on the RFL 9125 power supply in the ON (up) position.
It will initialize and run through a diagnostic routine; this will take about 90 seconds. When the letters "PL"
appear in the STATUS display, the RFL 9660 is ready for use. "PL" means the RFL 9660 is polling its local and
modem ports, looking for a connection.

RFL 9660 RFL Electronics Inc.

October 1, 1999 3-3 [phone]

3.5 MASTER RESET

The RFL 9660's master reset function returns all switch configuration settings (such as passwords, callback
strings, delay times) to their factory-default values. This will erase any new configuration settings stored in the
RFL 9660's memory, and return all switch configuration parameters to the settings they had when the RFL 9660
left the factory. The master reset can also be used to reset all port parameters (such as baud rate, flow control,
port label) to their factory default settings.

If you need to initiate a master reset, use the following procedure:

1. Turn off the RFL 9660 by placing the power switch on the power supply in the off (down) position.

2. Press and hold in the REMOTE LOCAL switch on the front of the RFL 9660.

3. While holding in the REMOTE LOCAL switch, turn on the RFL 9660 by placing the power switch on the
power supply in the on (up) position and look at the STATUS display.

After about two seconds, the STATUS display will read "rC," meaning the switch
passwords are about to be reset. The display will change to "00" once the passwords
are reset.

4. If you only want to reset the passwords, release the REMOTE LOCAL switch when "00" appears on the
STATUS display and go to step 5. If you also want to reset all the configuration parameters, keep
holding the REMOTE LOCAL switch.

After about eight more seconds, the STATUS display will read "rP," meaning the
configuration parameters are about to be reset. The display will change to "00" once the
configuration parameters are reset.

5. Watch the STATUS display.
When the RFL 9660 has completed its reset routine and is ready for use, the STATUS
display will read "PL." This means that the RFL 9660 is idle (not being accessed), but
polling its local and modem ports for connection.

3.6 LOCALLY ACCESSING THE RFL 9660

Once you have connected the local terminal to the RFL 9660's local port and the RFL 9660 is turned on, you
can access the RFL 9660 by pressing the [ENTER] key on the terminal keyboard. When you do, the following
message will appear on your display:

Site ID.
Enter <CR> for access.

When you press the [ENTER] key, the following prompt appears:
LOCAL> _

Your local terminal is now accessing the RFL 9660. Each time you press a key on the local terminal's keyboard,
the green DATA indicator on the RFL 9660's CPU module will light. This shows that the RFL 9660 is receiving
data from the local terminal.

If the RFL 9660 does not respond, check the connections between the local terminal and the RFL 9660's local
port. If the connections are good, make sure the terminal's configuration setting match that of the RFL 9660's
local port (2400 baud, 8 data bits, 1 stop bit, no parity). If the connections are good and the configuration
settings match, the RFL 9660 may require servicing. (See Section 12.)

If this is the first time you are using the RFL 9660 (or if passwords have not been enabled), you will be logged
on as the "super-user." If you press the [H] and [ENTER] keys, a list of super-user commands will appear. (See
Figure 3-3.) The relationships between these commands are shown in Figure 3-4.

Esc -Abort command
H -Help
D -Run diagnostics
I -Port Information
Q -Quit session
Port #/Label -Port selection
P -Program port
C -Configure switch
S -Save changes
R -Reset port parameters
U -Update hardware
MODEM -Connect Local port to Modem port.

LOCAL> _

Figure 3-3. List of super-user commands

If passwords have been set up and you did not use the super-user password, you will be logged on as a regular
user; pressing the [H] and [ENTER] keys will display a list of general access commands, as described in
Section 5. If this happens, terminate the session by pressing the [Q] and [ENTER] keys, and start another
session by pressing the [ENTER] key again. When the prompt appears asking for a password, enter the super-
user password. You cannot perform the procedures in this section unless you are logged on as a super-

user.

NOTE

"Esc" and "Q" are universal commands. "Esc" will abort any command entry if it is pressed before you
press the [ENTER] key. "Q" will terminate the session; it will also move you from the configuration
modes back to the regular mode. The "S" command saves any changes you have made to the switch
or port configuration settings. Always save your changes before you quit the session; otherwise, your
changes will be erased.

3.8 SETTING PASSWORDS

Passwords can be used to control access to the RFL 9660. When passwords are used, nine regular users (and
one super-user) will be able to use the RFL 9660. Each time someone calls into the RFL 9660, they will be
asked to enter their password. They will have to enter it correctly to use the RFL 9660. In addition, the
RFL 9660 keeps track of how many times each user calls in.

CAUTION

The super-user password (Password #3) must be entered before you enable passwords. If you
enable passwords w ithout a super-user password in the RFL 9660's memory, all future super­user access will be prohibited. A master reset will have to be performed to correct this
condition; this will erase all switch and port configuration settings.

There are ten passwords, numbered 1 through 10. Password 3 is reserved for the super-user.
All other passwords are for regular users. If passwords are not set up, all users will be able to
access the RFL 9660 as super-users. This is not recommended, because super-users can
make configuration and port changes.

Passwords are case-sensitive. Once you enter a password, it must be entered the same way
each time it is used; otherwise, the RFL 9660 will not accept it.

To set and enable passwords, use the following procedure:

1. Press the [C] and [ENTER] keys.

The "LOCAL>" prompt will change to a "CONFIG>" prompt. This shows that the
RFL 9660 is in the configuration mode.

2. Press the [H] and [ENTER] keys.
A list of configuration commands will appear on the terminal screen, as shown in
Figure 3-5. Listed next to each command is its meaning, range limits, and default
settings. You should not have to change most of these parameters, unless the
equipment in your installation requires longer delay times. (Refer to Section 5 for
more information on the configuration commands.)

3. The super-user password must be set first. To do this, enter the following command:
CONFIG> PW 3 desired password [ENTER]
The password can be any character string (letters, numbers, or symbols) up to seven characters long.

The password should not be something obvious, like a location name or a substation number; that
would make it easier for unauthorized persons to access the switch.

4. Once the super-user password is set, set all the regular user passwords you need by entering the
following command:

CONFIG> PW password number, space, desired password [ENTER]
Like the super-user password, user passwords can be any character string (letters, numbers, or

symbols) up to seven characters long, and should not be something obvious. Only set up as many
passwords as you need; unused passwords can be set up later if you need to add more users.

5. To view all the passwords you have set up, press the [S] and [ENTER] keys.

A list of all current configuration settings will appear on your display, as shown in
Figure 3-6. The passwords you entered are listed at the top. If any password needs to be
changed, re-enter it by repeating step 4.

7. Save the changes you have made by pressing the following command:
CONFIG> CS [ENTER]
The following message will appear:

Please wait.............

Periods will be added to the line as the changes are being stored. When storage is complete, the
"CONFIG>" prompt will reappear.

8. Exit the configuration mode by pressing the [Q] and [ENTER] keys.

The "CONFIG>" prompt will change back to the "LOCAL>" prompt. This shows that the
RFL 9660 has left the configuration mode.

The passwords have now been set. To start using passwords, press the [Q] and [ENTER] keys to terminate the
current session, and then press the [ENTER] key again to access the RFL 9660 and start another session. The
RFL 9660 will ask you for your password; enter the super-user password you just entered (Password 3) and
then press the [ENTER] key. The RFL 9660 will log you on as User 3 and return the "LOCAL>" prompt to your
terminal.

Once passwords are set up and enabled, the RFL 9660 keeps track of how many times each password is used
to access the RFL 9660. This information is displayed in the "Use" column of the list of current selections. (This
is Figure 3-5, displayed by using the "S" command while in the configuration mode). The RFL 9660 will tally
65,536 uses for a password before it is reset to zero.

3.9 ADDING CALLBACK STRINGS TO PASSWORDS

"Callback strings" can be added to any or all RFL 9660 passwords. These strings will tell the RFL 9660 to hang
up and call the user back at a certain preprogrammed phone number. This is an extra precaution that helps
prevent unauthorized switch access.

The following control codes may be embedded in a callback string:

\H Hang up and pause 30 seconds.
\N Insert a carriage return.
\D Wait until carrier is detected or 60 seconds has passed, If carrier is detected, pause for another

5 seconds.

\, Pause 5 seconds.
\. Pause 60 seconds.

\X "X" is a number from 1 to 9. The callback string will be repeated this many times or until a

carrier is detected. The the RFL 9660 will parse the remainder of the string.

RFL 9660 RFL Electronics Inc.

October 1, 1999 3-11 [phone]

A typical callback string is shown below:
\HATDT5551234\N\D\4
\H This tells the RFL 9660 to hang up and wait 30 seconds.
ATDT5551234 This tells the RFL 9660 to tone-dial "555-1234."
\N This tells the RFL 9660 to insert a carriage return.
\D This tells the RFL 9660 to wait until carrier is detected or 60 seconds. If carrier

is detected, the RFL 9660 will pause 5 more seconds.
\4 This tells the RFL 9660 to repeat the string up to 4 times if carrier is not

detected within 60 seconds.
\N This tells the RFL 9660 to insert another carriage return.
Spaces are not permitted in a callback string.
To enter a callback string for any of the active passwords, use the following procedure:

1. Press the [C] and [ENTER] keys.

The "LOCAL>" prompt will change to a "CONFIG>" prompt. This shows that the
RFL 9660 is in the configuration mode.

2. Set a callback string by entering the following command, followed by the [ENTER] key. Do not include
any spaces in the callback string:

CB space, password number, space, desired callback string [ENTER]
For example, to have the RFL 9660 hang up and call the user at 555-1234 when Password #2 is

entered, you would enter the following command:
CB 2 \HATD5551234\N\D\4 [ENTER]

3. Repeat step 2 for any other passwords that require callback strings. You can always add more callback
strings later if needed.

4. To view all the callback strings you have set up, press the [S] and [ENTER] keys.

A list of all current configuration settings will appear on your display, as shown in
Figure 3-7. The callback strings you entered are listed at the top, next to their passwords.
If any callback string needs to be changed, re-enter it by repeating step 2.

5. When all the callback strings you need are entered correctly, save them by entering the following
command:

CONFIG> CS [ENTER]
The RFL 9660 will send the following prompt to your terminal:

Are you sure? (Y/N) _

3.10 SETTING PORT CONFIGURATIONS

Each of the RFL 9660's device ports must be set to match the interface requirements of the device connected to
it. During installation (Section 2), you listed these devices in the table in Section 12, next to the port to which
they are connected. If you have not finished filling in this table, do it now. You will need this information during
the following procedures. (Refer to the manufacturer's documentation for the device connected to each port or
the application notes in Section 15 of this manual for the information you will need to complete the table in
Section 12.)

3.10.1 ENTERING THE PORT CONFIGURATION MODE

To set port configuration, you most enter the port configuration mode. To do this, you must be logged on to
the RFL 9660 as a super-user, with the "LOCAL>" prompt on your terminal. If the "CONFIG>" prompt is

shown, you are still in the switch configuration mode; press the [Q] key to return to the "LOCAL>" prompt.

1. Press the [P] and [ENTER] keys.

The RFL 9660 will send the following prompt to your terminal:
LOCAL> Port # _

2. Enter the number of the port to be programmed, and then press the [ENTER] key.
If you enter a number that is greater than the number of ports the RFL 9660 has, the following error

message will appear:
Cannot select port > than (maximum number of ports)
If you enter a number between one and the maximum number of ports the RFL 9660 has (8, 16, 24, or

32), a port information display similar to the one shown in Figure 3-8 will appear.

If you have a printer connected to your terminal, it would be helpful to print out this
screen. You would then have a hard copy to refer to during the rest of this procedure.

3. To change any of the entries on the port information display, press the [Y] and [ENTER] keys.
The port information display will reappear, with a list of selections at the bottom. (See
Figure 3-9.) Below the list of selections, the "LOCAL>" prompt will change to a
"PORT n >" prompt, with "n" being the number of the port you selected during step 2.
Each time you change one of the port configuration settings, this screen will be re­ displayed with the change you made entered on it. To correct a change, simply make
the change again.

If you don't want to change any of the settings, press the [N] and [ENTER] keys. The
"LOCAL>" prompt will reappear and you will no longer be in the port configuration
mode.

3.10.2 SETTING THE PORT LABEL

The port label is a unique character string that can be used to identify the device attached to one of the
RFL 9660's ports. Once set, the port label can be used to select the port you want to access. When you are
granted access to the port, the port label will appear at the top of the port information display, next to the port
number. Port labels are also listed on the port summary table when it is displayed. (See Section 4.)

To enter or change a port label, use the following procedure:

1. Press the [A] and [ENTER] keys. The following prompt will appear on your display:

Old label was old label - will be blank if there is no old label
Please enter new label, up to 30 characters. _

2. Enter the new port label, followed by the [ENTER] key.
Port labels can be any combination of letters, numbers, symbols, and spaces that is
30 characters or less.

NOTE

Like passwords, port labels are case-sensitive. Once you enter a port label, all users must enter it

the same way you did; otherwise, the RFL 9660 will not accept it.

3.10.3 SETTING THE COMMUNICATIONS PARAMETERS

The "M" selection lets you set the port's communication parameters to match those of the device connected to
it. It is usually best to match the port's communication parameters to the device, rather than modifying the
device's parameters to match the port. (Refer to the application notes in Section 15 or the manual supplied with
the device for more information on the settings you will have to make. If you cannot find the information you
need in either place, contact the device's manufacturer.)

To set the communication parameters, press the [M] and [ENTER] keys. The following prompt will appear on
your display:

Baud: 0 = 300 1 = 1200 2 = 2400 3 = 4800 4 = 9600 5 = 19.2K: _

Enter the number that matches the baud rate of the device connected to the port, and then press the [ENTER]
key. The following prompt will appear on your display:

Data bits: 7 or 8: _

Enter the number that matches the number of data bits for the device connected to the port, and then press the

[ENTER] key. The following prompt will appear on your display:
Parity: 0=none, 1=even, 2=odd: _

Enter the number that matches the parity of the device connected to the port, and then press the [ENTER] key.
The following prompt will appear on your display:

Stop bits: 1 or 2: _

Enter the number that matches the number of stop bits for the device connected to the port, and then press the
[ENTER] key. The updated port information display and list of selections will be re-displayed, containing the
new parameter settings.

3.10.4 SETTING THE PORT PASSWORD

The port password is a character string that must be entered before a user is allowed to access a device port. If
a password is set for a device port, all users will be asked to enter the password each time they try to access
the port. They will not be granted access unless they enter the password correctly.

To enter or change the password assigned to the selected device port, press the [D] and [ENTER] keys. The
following prompt will appear on your display:

Enter new password: _
The port password can contain up to seven characters. Port passwords do not have to be unique; in fact,

groups of devices can be assigned the same port password. For example, you may want to give all the relays at
the substation the same password, so only the relay engineers can access them. Once you have entered the
port password, press the [ENTER] key.

NOTE

Port passwords are case-sensitive. Once you enter a port password, all users must enter it the

same way you did; otherwise, the RFL 9660 will not accept it.

3.10.5 SETTING PORT FLOW CONTROL

The "j," "k," and "l" selections allow you to set flow control for the port. "Flow control" governs the rate at which
information passes between the RFL 9660 and the device connected to the port. Without flow control, data to
and from the device might be corrupted. The flow control setting must be set to match the flow control
requirements of the device connected to the port. (Refer to the manual supplied with the device or contact its
manufacturer for more information.)

The RFL 9660 uses character-based flow control for "outbound" messages from the RFL 9660 to the device.
Messages going from the device to the RFL 9660 ("inbound" messages) are fed to a 256-character buffer. The
RFL 9660 will exercise its flow control for inbound messages after 128 characters are sent to the buffer. This
gives the sending device 128 characters to start using its flow control. If the buffer fills up before the device halts
its output in response to the RFL 9660's handshake, data corruption will occur.

To set flow control for the port, use the following procedure:

1. Press the [L] and [ENTER] keys.

The following prompt will appear on your display:
0 None

1 RTS/CTS
2 DSR/DTR
3 XON/XOF

_
This selection lets you specify the flow control method the port will use.

2. Select the flow control method you want from the list on the screen, enter the number next to it, and
then press the [ENTER] key.

RFL 9660 RFL Electronics Inc.

October 1, 1999 3-17 [phone]

3. Press the [K] and [ENTER] keys.
The following prompt will appear on your display:

Enable XON/XOFF at Modem & Local [Y]: _
This selection lets you determine whether the LOCAL and MODEM ports will use

XON/XOFF flow control when communicating with this port. As shown in the prompt,
this can be set to "Y" or "N," with "Y" being the default value.

4. Press the [Y] key to enable XON/XOFF flow control, or the [N] key to disable it. Once you have entered
your choice, press the [ENTER] key.

Only set this selection to "N" (disable XON/XOFF flow control) if the device connected
to the port uses the XON/XOFF characters for data, and not for flow control. If you are
not sure about how to set this parameter, set it to "Y" (enable XON/XOFF flow control).

If you enter an "n," the following prompt will appear on your display above the list of
selections:

Do NOT operate Modem/Local ports above 9600 baud (if the new modem is
installed)

5. Press the [J] and [ENTER] keys.
The following prompt will appear on your display:

Monitor Local port DTR {Y/N} [Y]: _
This selection lets you determine whether the DTR line will be monitored at the LOCAL

port. As shown in the prompt, this can be set to "Y" or "N," with "Y" being the default
value.

6. Press the [Y] key to enable DTR line monitoring, or the [N] key to disable it.
If you enable local port DTR monitoring, the RFL 9660 will disconnect the user if the
DTR line goes active. Set this selection to "N" (disable DTR monitoring) if the
application software for the device connected to this port toggles the DTR line during
communications sessions. Failure to do this will cause the RFL 9660 to disconnect
while you are running the application program.

7. Once you have entered your choice, press the [ENTER] key.

3.10.6 SETTING CALLOUT FUNCTIONS

The callout functions will only have to be set if you want the device connected to the port to dial out through the
RFL 9660. An example of this would be a digital fault recorder (DFR) that would dial up a specific phone number
when a fault is detected. The callout functions include the following:

o Call Out
o Call Request
o Call String
o Call Priority

If the Application Note or device manual indicates that any of these functions should be reset, use the following
procedure; otherwise, go on to the next procedure.

1. Press the [C] and [ENTER] keys.

The following prompt will appear on your display:
Request Enable (Y/N) _
This selection lets you control whether the DTE connected to the port can call out

through the RFL 9660.

2. Press the [Y] key to enable callout requests, or the [N] key to disable it. Once you have entered your
choice, press the [ENTER] key.

3. Press the [B] and [ENTER] keys.

The following prompt will appear on your display:
0 None

1 RTS+DTR
2 DTR+RTS
3 RTS
4 DTR

Enter Mode (0 - 4): _
This selection lets you specify the call request method. This controls how the port

device request lines will request connection to the RFL 9660.

4. Select the call request method you want from the list on the screen, enter the number next to it, and
then press [ENTER].

5. Press the [E] and [ENTER] keys.

The following prompt will appear on your display:
Enter new dialback string (<=40 chars.): _

This selection lets you store a call string for the port. This is a character string containing a telephone
number and modem commands that the port can use to dial out. The following control codes may be
embedded in the callback string:

\H Hang up and pause 30 seconds.
\N Insert a carriage return.

RFL 9660 RFL Electronics Inc.

October 1, 1999 3-19 [phone]

\D Wait until carrier is detected or 60 seconds has passed, If carrier is detected, pause for
another 5 seconds.

\, Pause 5 seconds.
\. Pause 60 seconds.
\X "X" is a number from 1 to 9. The callback string will be repeated this many times or

until a carrier is detected. The the RFL 9660 will parse the remainder of the string.
A typical dialback string is shown below:
\HATDT5551234\N\D\4

\H This tells the RFL 9660 to hang up and wait 30 seconds.
ATDT5551234 This tells the RFL 9660 to tone-dial "555-1234."
\N This tells the RFL 9660 to insert a carriage return.
\D This tells the RFL 9660 to wait until carrier is detected or until

60 seconds has passed. If carrier is detected, the RFL 9660 will pause
5 more seconds.

\4 This tells the RFL 9660 to repeat the string up to 4 times if carrier is
not detected within 60 seconds.

6. Once you have entered the new call string, press the [ENTER] key.

7. Press the [I] and [ENTER] keys.

The following prompt will appear on your display:
Port's priority {0 is lowest} (0 - 9): _
This selection lets you assign a call priority level to each port.

8. Enter the priority level you want (a low number for low priority, a high number for top priority). Once you
have entered the priority level, press the [ENTER] key.

A high-priority call will not terminate a low-priority call that is already in progress. If a
port with a high priority initiates a call at the same time as a port with a low priority, the
higher priority call will go through first.

3.10.7 SETTING SPECIAL PORT CONFIGURATION FUNCTIONS

The following function settings normally do not have to be changed. The factory default settings should work
with most substation devices. These special functions include the following:

o Remote String (future enhancement)
o Port String (future enhancement)
o Modem String (for changing the internal modem's configuration upon output selection)

If the Application Note or device manual indicates that any of these functions should be reset, use the following
procedure; otherwise, go on to the next procedure.

1. If you need to enter a modem string, press the [F] and [ENTER] keys. If you don't need to enter a
modem string, go to step 4.

The following prompt will appear on your display:
Enter modem setup string (<=30 chars.): _
This selection lets you store a modem string for the port. This is a character string that

the port uses to send setup commands to the modem.

2. Enter the desired modem string. The following control codes may be embedded into the modem string:

\N Insert a carriage return.
\D Wait until carrier is detected or 60 seconds has passed, If carrier is detected, pause for another

5 seconds.

\, Pause 5 seconds.
\. Pause 60 seconds.
\+ Pause five seconds, send the "+++" modem escape code, and then pause five more seconds.

This control code is used to send the escape code through one modem to another. (If you
inserted the "+++" escape code into the callback string, it would be intercepted by the first
modem, placing it in the command mode.)

\X "X" is a number from 1 to 9. The modem string will be repeated this many times or until a
carrier is detected. The the RFL 9660 will parse the remainder of the string.

A typical modem string is shown below:
\+AT\X1 O\,
\+ This tells the RFL 9660 to pause five seconds, send the "+++" modem escape

3.11 USING THE RFL 9660 AS A SUPER-USER

Once the basic switch and port configuration settings have been made, the RFL 9660 is ready for regular use.
There may be cases where some of the configuration settings will have to be changed to make the RFL 9660
compatible with the equipment in your substation or your telephone system. If you need to make additional
configuration setting changes, refer to Section 5 for more detailed information.

Once passwords are set up and enabled, people who access the RFL 9660 as regular users can only use the
general access commands described in Section 5 of this manual. They will not be able to use any of the super­user commands, and will not be able to change any of the configuration settings.

NOTE

When you are finished using the RFL 9660, use the "Q" command to terminate the session and then
disconnect the terminal and cable from the RFL 9660's LOCAL connector.

Section 4. USING THE SWITCH

4.1 INTRODUCTION

The commands in this section can be used by all RFL 9660 users to run diagnostic checks, access device
ports, and display port information. If you are logged onto the RFL 9660 as the "super-user," you can also use
the configuration commands described in Section 5 of this manual.

To use the general access commands, you must have a PC with a 286 (or better) processor and a Hayes­compatible modem. The PC must be equipped with either Microsoft Windows (Version 3.1.), or a terminal
emulator program. A mouse is optional but its presence will simplify use, especially when running Windows.
Windows is recommended because it contains a terminal emulator and has multi-tasking capabilities. However,
some application software packages for substation equipment contain emulation programs, eliminating the need
for a separate program.

4.2 SETTING UP THE MODEM

Before trying to access the RFL 9660 from a remote PC or terminal, you must have a Hayes-compatible
modem. This can be a plug-in card inside your PC, or an external modem. The following settings must be
changed on your modem to make it compatible with the RFL 9660. Refer to the manual furnished with your
modem for more information on how to make these settings.

AUTO-ANSWER The modem's auto-answer function must be enabled. This will allow the RFL 9660 to
call your modem if the RFL 9660's callback feature has been enabled. You can enable
auto-answer by issuing an "ATS0=2" command; this will tell your modem to answer a
call after two rings.

DTR You must set your modem to ignore its DTR (Data Terminal Ready) line. This will stop
your modem from hanging up when you are switching between application programs.
You can tell your modem to ignore the DTR line by issuing an "AT&D0" command.

ERROR DETECTION If your modem supports v.42 or MNP error detection, it should be enabled; this is what

the RFL 9660 uses. If your modem uses any other form of error detection, it must be
disabled.

4.3 USING MICROSOFT WINDOWS TO LOAD AND RUN APPLICATIONS

The following procedure will set up Microsoft Windows for use with the RFL 9660. Windows is optional, but it is
recommended because of its multi-tasking capabilities. This will make it easy to switch from one application
software package to another while you are accessing the RFL 9660.

If you want to use Windows to load and run your applications software and you don't have Windows installed on
your PC yet, install it now. Refer to the documentation supplied with your Windows diskettes for instructions on
how to do this.

RFL 9660 RFL Electronics Inc.

April 24, 2007 4-1 [phone]

The following procedure was written for users with some experience with Microsoft Windows. If you have never
used Windows before, refer to the manuals supplied with Windows for information on running the Windows
Tutorial. Make sure you are comfortable with the Windows Tutorial before trying to use Windows to access the
RFL 9660.

The "Accessories" window will appear on top of the "Switch Applications" window.

6. Click on the "Window" menu name, and then click on "Tile" in the menu that appears.

This will "tile" the open windows (display them next to each other, rather than on top of
each other). This will allow you to move icons from one window to another.

7. Click on the "Terminal" icon in the "Accessories" window, and drag it over to the "Switch Applications"
window. When it is in the "Switch Applications" window, release the mouse button.

8. Look for all the other switch application icons in the "Accessories" window. When you find one, click on
its icon and drag it over to the "Switch Applications" window. When it is in the "Switch Applications"
window, release the mouse button. Repeat this process for all switch application icons.

9. If you have some applications software programs that you haven't loaded into your PC yet, load them
in now and place their icons in the "Switch Applications" window. Refer to the manuals supplied with
your Windows diskettes for more information on how to do this.

Windows is now set to run with the RFL 9660. All the application software programs and the Windows Terminal

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.

Your local terminal is now accessing the RFL 9660. Each time you press a key on the

local terminal's keyboard, the green DATA indicator on the RFL 9660's CPU module will
light. This shows that the RFL 9660 is receiving data from the local terminal.

If the RFL 9660 does not respond, check the connections between the local terminal and
the RFL 9660's local port. If the connections are good, make sure the terminal's
configuration setting match that of the RFL 9660's local port (2400 baud, 8 data bits,
1 stop bit, no parity). If the connections are good and the configuration settings match,
the RFL 9660 may require servicing. (See Section 11.)

8. If you are receiving "LOCAL>" prompts and you would like to see a list of all the commands available

to you, press the [H] and [ENTER] keys.

A list of general access commands will appear on your display, with the "LOCAL>"

The following information appears in the port summary table:
# Port number (1 to 32). As more device port modules are added to the RFL 9660, more

lines will appear on this table, one for each installed port.

TYPE Type of connection ("RS232" for RS-232, or "FO" for fiber optic).

LABEL The name assigned to the port by the super-user. This is an optional field that may

contain up to 30 ASCII characters.

NOTE

Port labels are case-sensitive. If the port label was entered as all CAPITALS, you will have to enter

it that way for the RFL 9660 to accept it.

MODE Request connect method assigned to this port:
0 Port Callout not enabled.
1 RTS + DTR
2 DTR + RTS
3 RTS
4 DTR
9 Disabled by the switch. This means that a device timeout occurred and the RFL 9660

disabled the callout feature for that port. When this happens, the super-user will have
to use the "P" command to manually reset the port callout feature. (See Section 5.)

RFL 9660 RFL Electronics Inc.

DTR This is an activity indicator; it will be "0" if DTR is not active, and "1" if it is active.

RTS This is an activity indicator; it will be "0" if RTS is not active, and "1" if it is active.

CallBack This is an enable indicator; it will be "Y" if callback is enabled, and "N" if it is not.

Q - QUIT SESSION

To disconnect your terminal from the RFL 9660 and end the session, use the "Q" command.
Format: REMOTE> Q [ENTER]
If you are using the Microsoft Windows Terminal Emulator, you can also disconnect your PC

from the RFL 9660 by clicking on "Phone" in the menu line, and then clicking on "Hang Up" in
the menu that appears. This will make your modem go on-hook.

Whichever method you use, the following message will appear on your display:
User terminates the session
The RFL 9660's STATUS display will read "hu," meaning that the RFL 9660 has begun its

hang-up sequence. When it is completed, the STATUS display will read "0" for a few seconds,
and then "PL." The RFL 9660 is then ready to start another session.

Port #/Label - PORT SELECTION

To connect your PC or terminal to one of the device ports on the back of the RFL 9660, enter
the port number or its label, and then press the [ENTER] key.

Format: REMOTE> port number or label [ENTER]
If you enter a number that is greater than the number of ports the RFL 9660 has, the following

error message will appear:
Cannot select port > than (maximum number of ports)
If you enter a number between one and the maximum number of ports the RFL 9660 has (8,

16, 24, or 32), the RFL 9660 will connect your terminal to that port.
If the super-user has enabled passwords, the following prompt will appear on your terminal:

Please enter password:

RFL 9660 RFL Electronics Inc.

April 24, 2007 4-32 [phone]

Enter the password on the keyboard, one letter at a time. 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.

When you finish entering the password, press the [ENTER] key. If the RFL 9660 accepts the
password, your terminal will be connected to the device port. If it does not accept your
password, you will have to re-enter it.

Once your terminal is connected to the device port, the RFL 9660 is transparent to the
system and will only respond to the deselect code sequence ("BYE"). If this code interferes with
any of the application programs, notify the super-user. Only the super-user can change this
code. (See Section 5.)

4.8 DESELECTING A PORT

When you are finished using the device port, type in the deselect code, without pressing the [ENTER] key. (The
deselect code is usually "BYE," unless the super-user has stored another code in the RFL 9660's memory.)

Format: BYE (no [ENTER])
When the RFL 9660 receives the deselect code, it will disconnect you from the port (after a delay period that

can be changed by the super-user). Your normal prompt will appear again, and will be able to select another
port, or use any of the other general access commands. Also, other users will be able to use the device port you
were using.

If you forget to enter the deselect code and simply stop using your terminal, a timer inside the RFL 9660 starts
keeping track of the time. This timer is set at the factory for 10 minutes; it can only be reset by the super-user.
Once this timer times out, the RFL 9660 will disconnect your terminal from the device port. The RFL 9660 does
this to prevent one user from tying up a device and keeping other users from accessing it.

NOTE

The RFL 9660 will not respond if CTS/RTS or DTR/DSR flow control is involved and there is no device
connected to the selected port. You will have to wait for the timeout period to pass before the port will
be de-selected.

4.9 CONNECTING THE LOCAL AND MODEM PORTS

The "MODEM" command only appears if your PC is connected to the RFL 9660's front-panel LOCAL connector.
It allows you to connect the local port to the modem port for calling out to another substation. This also allows
you to change the factory-set configuration of the RFL 9660's modem (for example, the number of rings before
auto-answer).

To connect the local and modem ports, type in the word "MODEM," and then press the [ENTER] key.
Format: LOCAL> MODEM [ENTER]
The following prompt will appear on your display:

Local port connected to Modem port!
To alter type (deselect code)

When you are finished dialing out, type in the deselect code ("BYE"). The RFL 9660 will hang up and disconnect
the local port from the modem port. While it is doing this, the following message appears on your display:

Please wait...
When the RFL 9660 is ready for normal operation again, your normal prompt will reappear.

Section 5. CONFIGURATION COMMANDS

5.1 INTRODUCTION

In many installations, the person responsible for the RFL 9660 Digital Switch will want to control how the
RFL 9660 is configured and how users may gain access to it. This person (or some other authorized person)
would use the configuration commands in this section to control these functions. Since the people that normally
access the RFL 9660 are called "users," the person that uses the commands in this section is called the "super­user."

The configuration commands described in this section are only available to the system super-user. You may
wish to remove this section from the users' manuals. This would help prevent unauthorized modifications to the
system configuration.

NOTE

The super-user's password is always Password #3. If you do not enable password protection,
all users will be able to use the configuration commands described in this section. Since this is
not recommended, set up and enable passwords. (See Section 3.)

5.2 ACCESSING THE RFL 9660 AS A SUPER-USER

As a super-user, you can access the RFL 9660 either locally or remotely. To access it locally, follow the
instructions in Section 3 of this manual. To access it remotely with a PC and dial-up modem, refer to Section 4.

5.3 SUPER-USER COMMANDS

Besides the general access commands described in Section 4 of this manual, the RFL 9660 has configuration
commands that can only be used when you are logged on as a super-user. To view a list of these commands,
press the [H] and [ENTER] keys. This will tell the RFL 9660 to send a list of all super-user commands to your
