expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user.
1.1 RADIO AND TV INTERFERENCE
The Model 1180RC/1184RC generates and uses radio frequency
energy, and if not installed and used properly—that is, in strict accordance with the manufacturer’s instructions—may cause interference to
radio and television reception. The Model 1180RC/1184RC has been
tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart J of Part 15 of
FCC rules, which are designed to provide reasonable protection from
such interference in a commercial installation. However, there is no
guarantee that interference will not occur in a particular installation. If
the Model 1180RC/1184RC does cause interference to radio or television reception, which can be determined by turning the power off, the
user is encouraged to try to correct the interference by one or more of
the following measures: moving the computing equipment away from
the receiver, re-orienting the receiving antenna and/or plugging the
receiving equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).
In the event that the user detects intermittent or continuous product malfunction due to nearby high power transmitting radio frequency
equipment, the user is strongly advised to take the following steps:
1) Use only data cables with an external outer shield bonded to a
metal or metalized connector.
2) Configure the rear card as shown in Section 3.2 in this manual.
1.2 CE NOTICE
The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Technical
Support.
1.3 SERVICE
All warranty and non-warranty repairs must be returned freight prepaid and insured to Patton Electronics. All returns must have a Return
Materials Authorization number on the outside of the shipping container. This number may be obtained from Patton Electronics Technical
Service at (301) 975-1007, http://www.patton.com, or support@pat-
ton.com.
NOTE: Packages received without an RMA number will not be
accepted.
Patton Electronics’technical staff is also available to answer any
questions that might arise concerning the installation or use of your
Model 1180RC. Technical Service hours: 8AM to 5PM EST, Monday
through Friday.

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.
