Overview
Although RS-232 serial ports are found on almost every
computer, because of their slow transmission speeds, limited
range, and limited networking capabilities, they are not an
effective solution for industrial strength long distance
communications systems
Systems based on the RS-485 standard, however, utilize
different voltage lines for the data and control signals, so they are
not subject to the RS-232 limitations
The IC-485S / IC-485SI is a bidirectional converter that
transparently converts RS-232 signals to RS-485 signals (and
vice versa) The IC-485S / IC-485SI provides Point-to-Point;
Multidrop; and Simplex operations over distances of up to 1200
m (4000 ft ), thus permitting the creation of reliable long distance
data communications systems using standard computer
hardware

Switch Configuration
The IC-485S / IC-485SI’s operating mode parameters are set
with two slide switches:

SW1 sets the Device Mode

SW2 sets the Transmitting and Receiving Mode

Terminology
Explanations of the SW! and SW2 terms are given in the table
below:
Term Ex lanation
DCE Data Communications Equipment; if the IC-485S /
IC-485SI is going to be plugged into a DTE
device, the IC-485S / IC-485SI must be set to
DCE
DTE Data Terminating Equipment; if the IC-485S / IC-
485SI is going to be plugged into a DCE device,,
the IC-485S / IC-485SI must be set to DTE
TxON,, RxON This setting is used in Point-to-Point operations,,
in which the unit is always in Transmitting and
Receiving Mode
TxRTS, RxRTS This setting is used in Multidrop operations, in
which the unit is in Transmitting Mode when the
RTS signal is high, and is in Receiving Mode
when the RTS signal is low
TxRTS, RxON This setting is used in Multidrop Full Duplex
operations to monitor the RS-485 line signals
Receiving Mode is always ON Transmitting mode
only occurs when the RTS signal is high
- 10 -
Operating Modes
The IC-485S / IC-485SI supports four operating modes: Point-to-
Point; Multidrop; Simplex; and Monitor (IC-485S only) Point-to-
Point and Multidrop can be configured for Full or Half Duplex
Each of the operating modes is explained in the sections that
follow
Point to Point
A Point-to-Point configuration is one in which two devices,
located at two different places are linked for communication by a
pair of IC-485S or IC-485SI units There are two configurations:
Point-to-Point Full Duplex, and Point-to-Point Half Duplex
1. Point-to-Point Full Du lex

Point-to-Point Full Duplex uses reverse four wire cabling
as shown in the diagram below:

For both IC-485S / IC-485SI units, set SW1 to DCE or DTE
depending on what type of device the IC-485S / IC-485SI
will plug into (if it will plug into a DCE device, configure it
for DTE, and vice versa)

For both IC-485S / IC-485SI units, set SW2 to TxON,
RxON
