MULTI-FUNCTIONLINEDRIVER
Multi-Function
Line Driver
Use this line driver in just about any
RS-232 UTP or STP application.
KeyFeatures
perating asynchronously or
Osynchronously, 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 wire is connected using an RJ-45
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
