Black Box IC108A User manual

Send data at speeds
up to 115.2 kbps.
Switch the RS-232
interface for DCE or
DTE.
Version available with
opto-isolation to
prevent damage from
ground loops.
Link up to 32 devices
together in 2-wire
multipoint appli-
cations using IC109
models.
Bidirectional conver-
sion from RS-232 (V.24)
to RS-422/485.
Choose standalone or
rackmount versions.
T
ransmit data up to 4000 ft.
(1219.2 m) over 2- or 4-wire
lines in full or half-duplex.
And send it at speeds 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 one of the Opto-
Isolation models for protection
against ground-loop surges.
Transmits data fast—up to 115 kbps!
Plus three selectable modes of operation.
KeyFeatures
RS-232↔RS-485/422CONVERTERS
Specially designed circuitry
lets the converter inhibit the CTS
signal if the CD signal is present.
That way, a device on the 485 side
can act as a controller.
Data Enable Mode is also
faster—up to 64 kbps! So you
won’t lose data when you
transmit in Data Enable.
IC109A-R3 and IC109C protect one segment of your extended network
from problems that arise on the other. Inside the RS-232↔485/422
Converter Plus with Opto-Isolation, optical-isolation circuits convert
electrical signals to light and back again, to keep signal noise and
ground loops from crossing between segments of your RS-485
installation. That means the electrical noise from your factory floor
won’t affect your office communications, and the difference in ground
potential over long distances and between buildings won’t damage your
sensitive equipment.

In the application shown, an
industrial controller is used
to gather information from
several remote program-
mable logic controller
stations (PLCs). A system
protocol has been defined so
that all the PLCs receive the
information sent by the
industrial controller, but only
the remote station specific-
ally addressed will respond.
In this system, the industrial
controller and all the remote
stations are DTE devices.
