2.2 DESCRIPTION
The Model 1180RC/1184RC Single Fiber Rack Card Modem
accomplishes point-to-point RS-232/V.35 communication over a
single
optical fiber. Mounting in Patton’s cluster box and 1000R16P rack system. the Model 1180RC supports synchronous data rates to 256 Kbps,
and asynchronous data rates to 38.4 Kbps, and the Model 1184RC
supports synchronous data rates to 128 kbps and asynchronous data
rates from DC to 19.2 kbps.The Model 1180RC/1184RC automatically
adapts to hardware or software flow control. Synchronous timing can
be set for internal, external or receive loopback clock.
The Model 1180RC/1184RC features extended data rate circuitry
that allows for single fiber distances between 2.5 and 5 Km. Optical
fiber may be connected to the Model 1180RC/1184RC using an ST or
SMA type interface.The Model 1180RC/1184RC encodes the electrical
signal using 3B4B modulation. The electrical signal is then converted
to an optical signal and transmitted using an 880 nm light emitting
diode, communicating over a single 62.5µ multi-mode fiber.
The Model 1180RC/1184RC features two test modes: local and
remote loopback. These loopback tests are activated via the serial
communication interface on the rear card. The local loopback test
monitors the RS-232/V.35 to modem connection. The remote loopback
test monitors the condition of the connection between the modems.

3.0 CONFIGURATION
This section describes the location and orientation of the Model
1180RC/1184RC’s configuration switches and jumpers. Separate
descriptions are provided for the front “brains”card and the rear “interface” card.
3.1 FRONT CARD CONFIGURATION
The Model 1180RC/1184RC front card uses two sets of DIP
switches that allow configuration to a wide range of applications. DIP
switch set S1 has 4 switches and allows selection of data rates. DIP
switch set S2 has 8 switches and allows selection of clocking, handshake and test mode parameters.
Figure 1 (below) shows the location of switch set S1 and S2 on
the 1180RC/1184RC front card. Figure 2 (below) shows the orientation
of DIP switch set S2 (S1 is identical).
3.1.1 SWITCH SET S1 OVERVIEW
DIP switch set S1 has 4 switches and is used to select the data
rate. Below are Table 1 (Model 1180RC) and Table 1A (Model 1184RC)
which shows each possible data rate and switch settings.
Important: When the data rate is followed by “dbl”, the space
between data packets is doubled. This means communication distances up to 5Km are possible. When the data rate is followed by “std”,
the space between data packets is standard. This means communication distances are limited to 2.5 Km.

3.1.2 SWITCH SET S2 OVERVIEW
DIP switch set S2 has 8 switches and is used to specify clocking,
handshake and loopback modes. Table 2 (below) shows each setting
at a glance.
3.1.3 DETAILED SWITCH SETTINGS - S2
Whereas DIP switch set S1 is dedicated specifying data rates,
switch set S2 has multiple functions. Please refer back to Table 2,
above for an overview of all possible S2 configurations.
S2-1 & S2-2: Transmit Clock Selection
Switches 1 and 2 are used to specify the clocking method. The
Model 1180RC/1184RC can provide an internal clock, receive a clock
loopback, or receive an external clock. Internal clocking is the normal
(default) method.
S2-1 S2-2
On off = Internal Clock
(default setting)
off off = Received Loopback Clock
off On = External Clock
S2-3: Handshake Mode
The setting for switch 3 determines whether the Model
1180RC/1184RC operates in RTS/CTS (hardware) handshaking mode
or standard modem handshaking mode. In RTS/CTS mode, when one
unit drops RTS, CTS will drop on the other unit. In standard modem
mode, handshaking only functions on the local loops (between each
Model 1180RC/1184RC and its own DTE device).
S2-3

3.1.4 REVERSIBLE “DAUGHTER BOARD”
The Model 1180RC/1184RC supports both RS-232 and V.35 electrical interfaces for the terminal connection port. Which electr ical interface is active is determined by the orientation of the small reversible
daughter board on the front card (see Figure 3, below). The daughter
board is clearly marked “This side up for RS-232” and “This side up
for V.35”. Note: When plugging the daughter board into the socket, the
arrow should always point toward the
front panel
of the PC board.
3.2 REAR CARD CONFIGURATION
The Model 1180RC/1184RC is compatible with four single-fiber
rear interface cards. Figure 4 (below) shows a rear view of each of
the cards.

4.0 INSTALLATION
This section describes the functions of the Model 1000R16P rack
chassis, tells how to install front and rear Model 1180RC/1184RC
cards into the chassis, and provides instructions for connecting the
interface cables.
4.1 THE MODEL 1000R16 RACK CHASSIS
The 1000R16 Rack Chassis (Figure 8, below) has sixteen short
range modem card slots, plus its own power supply. Measuring only
3.5” high, the 1000R16 is designed to occupy only 2U in a 19” rack.
Sturdy front handles allow the 1000R16 to be extracted and transported conveniently.
4.1.1 THE RACK POWER SUPPLY
The power supply included in the Model 1000R16 rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by thumb screws and the rear card by
conventional metal screws.
Switching the Power Supply On and Off
The power supply on/off switch is located on the front panel.
When plugged in and switched on, a red front panel LED will glow.
Since the Model 1000R16P is a “hot swappable” rack,
it is not neces-
sary for any cards to be installed before switching on the power supply
.
The power supply may be switched off at any time without harming the
installed cards.
4.2 INSTALLING THE MODEL 1180RC/1184RC INTO THE CHASSIS
The Model 1180RC/1184RC is comprised of a front card and a
rear card. The two cards meet inside the rack chassis and plug into
each other via mating 50 pin card edge connectors. Use the following
steps as a guideline for installing each Model 1180RC/1184RC into the
Model 1000R16P rack chassis:
1. Slide the rear card into the back of the chassis along the metal
rails.
2. Secure the rear card using the metal screws provided.
3. Slide the front card into the front of the chassis. It should meet the
rear card when it’s almost all the way into the chassis.
4. Push the front card
gently
into the card-edge receptacle of the
rear card. It should “click” into place.
5. Secure the front card using the thumb screws.
NOTE: Since the Model 1000R16P chassis allows “hot swapping”
of cards, it is
not necessary to power down
the rack when you
install or remove a Model 1180RC/1184RC.
4.3 WIRING THE MODEL 1180RC/1184RC
Each of the rear interface cards compatible with the Model
1180RC/1184RC has one terminal interface port (DB-25 or M/34) and
a single multimode fiber port (ST or SMA). This section describes connection procedures for the terminal cable and fiber cable.
Figure 8. Model 1000R16 rack chassis with power supply
WARNING! There are no user-serviceable parts in the
power supply section of the Model 1180RC/1184RC.
Voltage setting changes and fuse replacement should
only be performed by qualified service personnel.

4.3.1 TERMINAL INTERFACE CONNECTION
The Model 1180RC/1184RC is wired as a DCE, and allows for
three possible terminal interface connections:
• RS-232C/V.24 (electrical) + DB-25 female (physical)
• V.35 (electrical) + DB-25 female (physical)
• V.35 (electrical) + M/34 female (physical)
To select the appropriate
electrical
interface, please refer to
Section 3.1.4 of this manual. To select or constr uct a cable with the
appropriate
physical
interface pin-outs, please refer to the diagrams in
Appendix B and Appendix C of this manual.
4.3.2 FIBER CONNECTIONS
The Model 1180RC/1184RC is designed to work with the standalone Model 1180, or with another Model 1180RC/1184RC. In either
case, you will need one unit at each end of a
single
fiber cable. This
cable connects to the Model 1180RC/1184RC using either an ST or an
SMA connector. Figure 9 (below) shows a close-up of each of these
connector types.
The cable must be multi-mode 50 or 62.5µ, for
optimal performance, use 62.5µ.
5.0 OPERATION
Once you have configured each Model 1180RC/1184RC and connected the cables, you are ready to operate the units. This section
describes the LED status monitors, the power-up procedure, and the
use of the built-in test modes.
5.1 LED STATUS MONITORS
The Model 1180RC/1184RC features eleven front panel status
LEDs that indicate the condition of the modem and communication link.
Figure 10 shows the front panel location of each LED. Following
Figure 10 is a description of each LED’s function.
• The green “PWR” LED glows when power is applied to the modem
card through its mid-plane chassis connection.
• The green “TD” and “RD” indicators blink to show positive state
data activity. The Red “TD” and “RD” indicators blink to show negative state data activity. Solid red indicates an idle state.
• The green “RTS”and “CD” indicators glow solid to show the con-
trol signal is on. The red “RTS” and “CD” indicators glow solid to
show the control signal is off. When the 1180RC/1184RC is connected to a DTE, RTS will glow green. CD will glow green for an
incoming signal from the line.
• The green “Test” LED glows when either test mode is activated.

5.2 POWER-UP
There is no power switch on the Model 1180RC/1184RC: Power is
automatically applied to the 1180RC/1184RC when its card-edge connector makes contact with the chassis’ mid-plane socket, or when the
chassis’ power supply is turned on.
Note:The 1180RC/1184RC is a
“hot swappable”card—it will not be damaged by plugging it in or
removing it while the rack is powered up.
When the local and remote
Model 1180RCs/1184RCs are
both
powered up, and are passing data
normally
, the following LED conditions will exist:
• PWR = green
• TD & RD = flashing red and green
• RTS & DCD = green
• TEST = off
5.3 LOOPBACK TEST MODES
The Model 1180RC/1184RC offers two loopback test modes to
evaluate the condition of the modems and the communication link (see
Figure 11, below). Both tests can be activated physically from the front
panel, or via the RS-232/V.35 interface.
5.3.1 ANALOG LOOPBACK
The Analog Loopback test checks the operation of the local Model
1180RC/1184RC, and is
performed separately on each unit.
Any data
sent to the local Model 1180RC/1184RC in this test mode will be
echoed (returned) back to the user device. For example, characters
typed on the keyboard of a terminal will appear on the terminal screen.
To perform an analog loopback test, follow these steps:
1. Activate Analog Loopback. This may be done in one of two
ways:(1) by moving the front panel toggle switch RIGHT to
“Analog”, (2) by raising the LAL signal pin on the RS-232/V.35
interface. Note: Make sure switch SW1-7 is enabled. Once
Analog Loopback is activated, the Model 1180RC/1184RC
transmit output is connected to its own receiver. The “TEST”
LED should be lit.
2. Verify that the data terminal equipment is operating properly
and can be used for a test.
3. Perform a BER (bit error rate) test on the system, using external test equipment.
4. Perform a BER test on each unit. If the BERT test equipment
indicates no faults, and the data terminal indicates a fault, follow the manufacturer’s checkout procedures for the data terminal. Also, check the RS-232/V.35 interface cable between
the terminal and the Model 1180RC/1184RC.
5.3.2 REMOTE LOOPBACK
The Remote Loopback test checks the performance of both the
local and remote Model 1180RCs/1184RCs,
and
the communication
link between them. Any characters sent to the remote Model
1180RC/1184RC in this test mode will be returned back to the originating device. For example, characters typed on the keyboard of the local
terminal will appear on the local terminal screen
after
having been
passed to the remote Model 1180RC/1184RC/1184RC and looped
back. To perform an RDL test, follow these steps:
1. Activate Remote Loopback. This may be done in two ways:
(1) by moving the front panel toggle switch LEFT to “Remote”,
(2) by raising the RDL signal pin on the RS-232/V.35 interface. Note: be sure that DIP switch SW1-8 is enabled.
2. Verify that the DTE equipment on the local end is operating
properly and can be used for a test.
3. Perform a BER test on the system, using external test equipment.
4. If the remote BER test indicates that errors
are
present, and
the local analog loopback/BER tests showed that both Model
1180RCs/1184RCs were functioning properly, this suggests a
problem with the FIBER between the two modems. If you still
have errors, call Patton Technical Support at (301) 975-1007.
