OVERVIEW:

The Omnitron iConverter RS232 is a manageable serial
RS-232 to fiber converter that transmits serial signals
over fiber media. Fiber transmission can extend serial
signals up to 120km and is immune from electrical and
magnetic interference. The RS232 is available with a
single-mode, multimode or single-fiber transceiver. The
serial port is available with a DB-9 female connector or
terminal block connector.

The RS232 automatically detects the signal baud rate of
the connected serial device, ranging from 110 to 921,600
baud. The RS232 automatically adjusts to changes in
the connected device’s baud rate during operation, without
reconfiguration or interruption.

Connection to DTE or DCE devices is configured by an
easily accessible DIP-Switch on the front-panel. A built­in remote Fiber Loop-Back DIP-Switch provides easy
validation of the entire fiber segment from either terminal
RS232 converter, without having to enable this function
on both converters.

The RS232 is designed to work in any
When installed in a multi-module chassis, the RS232 can

The
all support the software control feature. The 1-Module
chassis supports RS232 as a standalone serial to fiber
converter.

Note that software control for remote configuration
of the RS232 requires a multi-module chassis with

iConverter Management Module, such as the

an
Network Management Module (NMM).

RS232 via software control, please refer to the

PORT STRUCTURE:

Front-Panel Ports:

The front-panel of the
fiber port (P1) and one RS-232 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 and Fig. 1b for connector pin-out
assignment.

DIP-SWITCH SETTINGS:

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 RS232 at either
end of the fiber segment will enable the Fiber Loop-Back
test. When Fiber Loop-back is enabled, the local RS232
with the DIP-Switch in “FLB” position is the master, and
the remote RS232 with the DIP-Switch in “Norm” position
is the slave. The “Tst” LED on the master will blink rapidly
(10 times per second) and the “T st” 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 Loop­back test, the “Tst” LED on master unit will remain solid.

Note that the Fiber Loop-back test does not interfere
with serial conversion and signal transmission.

Note that only one RS232 on either end of the fiber
segment needs to be set to “FLB” position during
the Loop-back test.

SW2: Serial “DCE / DTE” DIP-Switch:

When the “DCE / DTE” DIP-Switch is in the “DCE” position
(factory default), the RS232 is configured to connect to
Data Communications Equipment such as a modem or

printer. Setting this DIP-Switch to the “DTE” position
configures the RS232 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.

MOUNTING AND CABLE ATTACHMENT:

iConverter modules are hot-swappable and can be installed

into any chassis in the

iConverter family.

1. After configuring the DIP-Switches, carefully slide

iConverter module into the installation slot, aligning

the
the module with the installation guides. Ensure that
the module is firmly seated against the Backplane.

2. Secure the module by fastening the panel thumb screw
(attached to the module) to chassis front.

3. Attach the serial ports via a DB-9 serial cable (or an
open-end serial cable) to a serial RS-232 device.

4. Attach the fiber port via an appropriate multimode or
single-mode fiber cable to a 100BASE-FX Fast Ethernet
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 8770-1 matched with the
8771-1.
