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.
