1.1 RADIO AND TV INTERFERENCE
The Model 1140A 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 1140A 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 interfer-
ence will not occur in a particular installation. If the Model 1140A does
cause interference to radio or television reception, which can be deter-
mined by disconnecting the RS-232 interface, the user is encouraged
to try to correct the interference by one or more of the following meas-
ures: moving the computing equipment away from the receiver, re-ori-
enting 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).
1.2 SERVICE
All warranty and non-warranty repairs must be returned freight pre-
paid and insured to Patton Electronics. All returns must have a Return
Materials Authorization number on the outside of the shipping contain-
er. This number may be obtained from Patton Electronics Technical
Service at (301) 975-1007.
Packages received without an RMA num-
ber 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 1140A. Technical Service hours: 8AM to 5PM EST, Monday
through Friday.

2.2 DESCRIPTION
The Patton Model 1140A miniature dual fiber optic modem brings
fiber to the desktop. Combining the inviolability of fiber with the trou-
bleshooting capabilities of V.52 and V.54 diagnostics, the Model 1140A
is the best choice for your most critical RS-232 links. The Model
1140A operates async. or sync., supports data rates to 57.6 Kbps and
plugs directly into a workstation’s RS-232 port.
Like all fiber optic modems, the Model 1140A is inherently immune
to RFI/EMI noise, ground loops and transient surges. The carrier may
be switch selected as either “Continuously On” or “Controlled by RTS”,
while an easily accessible DCE/DTE switch eliminates the need for
cumbersome RS-232 crossover cables. Two easy-to-read LED indica-
tors monitor the Error and Test modes. Drawing all necessary power
from the RS-232 interface, the Model 1140A requires no AC power or
batteries to operate.
Measuring only 3.42” x 2.10” x .73”, the Model 1140A is able to fit
into tight installation spaces. On the RS-232 side, the Model 1140A
comes equipped with either a male or female DB-25 connector; on the
fiber side, it is available with a choice of SMA or ST connectors.
