iConverter®RS422/485
Serial RS-422 and RS-485 to
Fiber Media Converter User Manual
OVERVIEW:
The Omnitron iConverter RS422/485 is a manageable
serial RS-422 or RS-485 to fiber converter that transmits
serialprotocoloverfibermedia.Fibertransmissionextends
serial signals up to 120km and protects against electrical
and magnetic interference.
TheRS422/485isavailablewithasingle-mode,multimode
or single-fiber transceiver. The serial port interface is
available with a DB-9 female connector or terminal block
connector for field wiring.
The RS422/485 automatically detects the signal baud
rate of the connected point-to-point Full-Duplex RS-422
serial devices, ranging from 110 to 921,600 baud. The
RS422/485 also automatically adjusts to changes in the
point-to-point Full-Duplex RS-422 baud rate during
operation,withoutinterruptingthedataservice. Connection
to DTE or DCE Full-Duplex point-to-point RS-422 devices
is configured by an easily accessible DIP-Switch on the
front-panel.
Half-Duplex RS-485 and Full-Duplex RS-485 (sometimes
referredas Multi-point RS-422) operation is supportedvia
a configurable baud rate DIP-Switch to match the master/
slave communication timing.
A built-in remote Fiber Loop-Back DIP-Switch provides
easy validation of the fiber segment. The Loop-Back
does not interrupt signal transmission over the fiber.
Built-in configurable terminators support Full-Duplex
and Half-Duplex operations, allowing the unit to be
deployed and terminated at any node in the serial line.
The RS422/485 is designed to work in any iConverter
chassis. When installed in a multi-module chassis with an
iConverter Management Module, the RS422/485 can be
remotely monitored and managed by software control.
Management is supported on the iConverter 19-Module,
5-Module and 2-Module chassis. The 1-Module chassis
supports RS422/485 as a standalone serial to fiber
converter.
Note that software control for remote configuration
of the RS422/485 requires a multi-module chassis
with an iConverter Management Module, such as the
Network Management Module (NMM).
For more information on using and configuring the
RS422/485 via software control, please refer to the
NetOutlook™Management Software user manual.
PORTSTRUCTURE:
Front-Panel Ports:
The front-panel of the iConverter RS422/485 features
one fiber port (P1) and one RS-422/485 capable serial
port (P2). Depending on the model, the serial port is
available either as a DB-9 female connector or as a
terminal block for field wiring. Please refer to Fig. 1a, Fig.

DIP-SWITCH SETTINGS:
Front-Panel DIP-Switches
Fig. 2 Front-Panel DIP-Switches
SW1: Normal and Fiber Loop-Back “Norm - FLB”
DIP-Switch:
When the Normal and Fiber Loop-Back “Norm - FLB”
DIP-Switch is in the normal mode “Norm” position (factory
default), the Fiber Loop-Back is disabled. Setting this
DIP-Switch to the “FLB” position on the RS422/485 at
either end of the fiber segment will enable the Fiber Loop-
Back test. When Fiber Loop-Back is enabled, the local
RS422/485 with the DIP-Switch in “FLB” position is the
master,and the remote RS422/485 with the DIP-Switchin
“Norm” position is the slave. The “Tst” LED on the master
will blink rapidly (10 times per second) and the “Tst” LED
on the slave will blink slowly (once per second) if the fiber
segment passes the Loop-Back test. If the fiber segment
fails the Loop-Back test, the “Tst” LED will remain solid on
the master unit.
Note that the Fiber Loop-back test does not interfere
with serial conversion and signal transmission.
Note that if both RS422/485 on the ends of a fiber
segment are set to the “FLB” position during the
Loop-back test, then both RS422/485 would still
display valid master mode results.
SW2: Serial “DCE - DTE” DIP-Switch:
Whenthe“DCE - DTE” DIP-Switch is in the “DCE” position
(factory default), the RS422/485 is configured to connect
to Data Communications Equipment such as a modem or
printer. Setting this DIP-Switch to the “DTE” position
configures the RS422/485 to connect to Data Terminal
Equipment such as a computer or controller. Please refer
to the PORT STRUCTURE section of this manual for
more details.
Note that the “DCE - DTE” DIP-Switch is disabled if
the RS422/485 is in Half-Duplex mode or in Multi-
point mode.

Bank1 SW5: Full/Half-Duplex “FDX/HDX” DIP-Switch:
When the Full/Half-Duplex selection DIP-Switch is in the
LEFT “FDX” position (factory default), the RS422/485
operates in serial Full-Duplex mode. Configuring the
DIP-Switch to the RIGHT “HDX” position enables serial
Half-Duplex mode, often used by the RS-485 protocol.
When the RS422/485 is in Half-Duplex mode, the point-
to-point/Multi-point DIP-Switch has no effect. Configure
the Half-Duplex Baud rate with Bank 1 DIP-Switches 1
through 4.

iConvertermodulesarehot-swappableandcanbeinstalled
into any chassis in the iConverter family.
1. After configuring the DIP-Switches, carefully slide the
iConverter module into the installation slot, aligning
the module with the installation guides. Ensure that
the module is firmly seated against the Backplane.
2. Secure the module by fastening the panelthumbscrew
(attached to the module) to the chassis front.
3. Attach the serial ports via a DB-9 serial cable (or an open-
end serial cable) to a serial RS-422 or RS-485 device.
4. Attach the fiber port via an appropriate multimode or
single-modefibercabletoa100BASE-FXFastEthernet
device. The iConverter transmit (Tx) must attach to
the receive side on the other device; the receive (Rx)
must attach to the transmit side.
5. When using single-fiber (SF) media converter models,
the Tx wavelength on one end has to match the Rx
wavelength on the other. Note that based on this
guideline, the SF media converter models must be
used in pairs, such as the 8790-1 matched with the
8791-1.
