1.1 RADIO AND TV INTERFERENCE

The Model 1140 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 tele-
vision reception. The Model 1140 has been tested and found to com-
ply 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 1140 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

2.2 DESCRIPTION
The Patton Model 1140 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 1140
is the best choice for your most critical RS-232 links. The Model 1140
operates async. or sync., supports data rates to 38.4 Kbps and plugs
directly into a workstation's RS-232 port.
Like all fiber optic modems, the Model 1140 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 1140 requires no AC power or
batteries to operate.
Measuring only 3.42" x 2.10" x .73", the Model 1140 is able to fit
into tight installation spaces. On the RS-232 side, the Model 1140
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.
