3.0  CONFIGURATION

This section describes the location and orientation of the Model

1140RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings. 

The Model 1140RC uses a combination of DIP switches and

jumpers that allow configuration to an extremely wide range of
applications.  Designed around a mid-plane architecture, the Model
1140RC incorporates both front and rear cards.  Configuration of both
may be necessary.  The switches/jumpers are accessible when the
cards are removed from the rack chassis.  Once configured, the Model
1140RC is designed to operate transparently, without need for frequent
re-configuration.

3.1  FRONT CARD CONFIGURATION

The Model 1140RC front card has two sets of eight switches (S1 &

S2), which are mounted on the PC board (Figure 1, below).  These
configuration switches allow you to configure the Model 1140RC for a
wide range of applications.  The ON/OFF orientation of the DIP
switches  is shown in figure 2 (below).

2.2  DESCRIPTION

The Patton Model 1140RC fiber optic rack card modem is the

rack mountable counterpart to Patton’s Model 1140 self-powered, fiber
optic modem.  Communicating full or half duplex over dual optical
fibers, the Model 1140RC supports data rates to 57.6 Kbps and
distances to 2 miles.  Both V.54 and V.52 diagnostics are built into the
unit.  Like all fiber optic modems, the Model 1140RC 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”.  Five pairs of bi-level LED indicators monitor  TD,
RD, RTS, CD, test and error.  A single LED monitors power.

The Model 1140RC is designed to mount in Patton’s 2U high 19”

rack chassis.  This 16-card chassis has a switchable 120/240 volt
power supply and mounts cards in a mid-plane architecture:  The front
“brains” half-card can be plugged into different rear “interface” cards.
The Model 1140RC is available with a choice of two interface cards:
one with SMA connectors, and one with ST connectors.  Both cards are
equipped with an HD-26 female connector for the RS-232 interface.
