13033 1.
Typical Speed vs. Distance
Send data at speeds up to
115.2 Kbps.
Switch the RS-232
interface for DCE or DTE.
Opto-Isolation prevents
damaging ground loops.
Link up to 32 devices
together in 2-wire multipoint
applications.
Available in standalone
and rackmount versions.
Bidirectional conversion
from RS-232 (V.24) to
RS-422/485.
T
ransmit data up to 4 miles
(6.4 km) over 2- or 4-wire
lines in full- or half-duplex.
And send it at speeds up to
up to 115.2 Kbps. Use these
Converters with PCs and
other RS-232 equipment that
has the 16550 UART.
Switch settings let you
customize the Converter to
your specific application.
Now set line bias to match
your 485 equipment, set the
line termination resistors, and
switch the RS-232 interface for
DCE or DTE.
Improved surge
suppression keeps your
Converter safe from induced
surges on the RS-485 side. If
you are transmitting between
buildings, or over long
distances, order the Opto-
Isolation for protection
against ground-loop surges.
Specially designed
circuitry lets the Converter
inhibit the CTS signal if the
Transmits data fast—
up to 115 Kbps! Plus
three selectable modes
of operation.
CD signal is present. That way
a device on the 485 side can
act as a controller.
Key Features
Data Enable Mode is also
faster—up to 64 Kbps! So you
won’t lose data when you
transmit in Data Enable.
