2.2 DESCRIPTION
The Patton Model 1094 Synchronous Short Range Modem
is designed for point-to-point, high speed communication over 4-wires
(two twisted pair). Supporting switch-selectable data rates of 384 and
768 kbps, the Model 1094 is perfect for connecting two bridge/routers,
or for similar campus applications at distances up to 4.9 miles (7.9 km).
The Model 1094 incorporates built-in V.54 loopback tests, a V.52 BERT
pattern generator and seven front panel LED indicators. Data integrity
is enhanced by automatic equalization and gain control. The Model
1094 also incorporates transformer isolation and surge protection to
guard data and connected equipment against the hazards of ground
loops and transient surges. Clocking options include internal, external
and receive recover clock.
The Model 1094 features replaceable DCE-DTE QuickConnect™
interface modules. Several different modules are available (call Patton
Sales for details). Line connection is made by RJ-45 jack. Internal AC
power supply options include 120 or 230VAC (switchable), 85-256VAC
(universal) or 48VDC.
3.0 CONFIGURATION
The Model 1094 is equipped with one set of eight DIP switches,
and one set of four DIP switches (all externally accessible). These DIP
switches allow configuration of clock source, carrier control, loopback
tests and data rate. This section describes switch locations and
explains all possible configurations.
3.1 EXTERNAL DIP SWITCH SETTINGS
The Model 1094’s DIP switches are located on the underside of
the unit (see Figure 1, below). Figure 2 shows the orientation of the
switch set. All possible settings for the Model 1094’s DIP switches are
presented in the summary table and descriptions on the following
pages.
