Function

-

Driver

Multi

Line

Use this line driver in just about any

RS-232 UTP or STP application.

Key Features

Speeds up to 38.4 kbps.

Distances up to 6 miles (9.7 km).

Async or sync operation, point-to- point or multipoint.

Operating asynchronously or synchronously, the Multi- Function Line Driver supports data rates up to 38.4 kbps and distances up to 6 miles (9.7 km).

The line driver will operate over 4 wires in point-to-point or multipoint environments. In synchronous mode, the Multi-

Function Line Driver supports internal, external, or receive loopback clocking.

Two V.54 and two V.52 BER test modes can be activated via the RS-232 interface. Built-in LEDs let you monitor test mode operation. With transformer

isolation and surge protection, your data is safe.

The Multi-Function Line Driver is designed to plug directly into the RS-232 interface. Twisted-pair wire is connected using an RJ-45 connector or terminal blocks with strain relief.

Transformer isolation and surge protection.
