OVERVIEW:
The Omnitron iConverter RS422/485 is a manageable serial RS-422 or RS-485 to fiber converter that transmits serial protocol over fiber media. Fiber transmission extends serial signals up to 120km and protects against electrical and magnetic interference.
The RS422/485 is available with a single-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, without interrupting the data service. 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 referred as Multi-point RS-422) operation is supported via 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
iConverter Management Module, such as the
with an Network Management Module (NMM).

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 Loop­Back 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-Switch in “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 “T st” 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:
When the “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 Multi­point mode.

These DIP-Switches are deactivated when the RS422/485 is operating in point-to-point Full-Duplex RS-422 Mode. Please see the Baud Rate Configuration T able for det ails.

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 point­to-point/Multi-point DIP-Switch has no effect. Configure the Half-Duplex Baud rate with Bank 1 DIP-Switches 1 through 4.
Bank1 SW6 and SW7: “RSV” DIP-Switches:
DIP-Switches 6 and 7 in Bank 1 are reserved for factory use and must be kept in the LEFT position.
Bank1 SW8: Full-Duplex Normal/Multi-Point “NORM/MP” DIP-Switches:
This DIP-Switch has no affect if the RS422/485 is in Half-Duplex mode. When this DIP-Switch is in the LEFT
Page 6
“NORM” position (factory default), the RS422/485 operates in a point-to-point Full-Duplex mode, commonly used by the RS-422 protocol. Baud rate selection is automatic in this mode.
When this DIP-Switch is in the RIGHT “MP” position, the RS422/485 operates in a Multi-point Full-Duplex mode, often referred as Full-Duplex RS-485 or Multi-point RS-422. In this mode, Baud rate must be manually configured via Bank 1 “BAUD” DIP-Switches 1 through 4. Please see the Baud Rate Configuration Table for details.
Board-Mounted Bank 2 DIP-Switches: Note that Bank 2 DIP-Switches are not accessible via
software control, and must be configured physically.
Fig. 5 Bank 2 DIP-Switch Description
Bank2 SW1 and SW2: Head Termination “HEAD” DIP-Switches:
Bank 2 Head Termination “HEAD” DIP-Switches 1 and 2 configure the RS422/485’s termination setting by providing termination on the data line. When these
-
DIP-Switches are in the LEFT “ no termination is provided. Setting these DIP-Switches to
” position (factory default),
the RIGHT “HEAD” position provides pull-up and pull­down on the data lines. See the T ermination T able on page 8 and Fig. 6 for details.
Note that both of the Head Termination “HEAD” DIP-Switches on a RS422/485 need to be set to the same position, failure to do so will result in unpredictable behavior.
Bank2 SW3 through SW6: Mid Termination “MID/H-T” DIP-Switches:
Bank 2 Mid T ermination “MID/H-T” DIP-Switches 3 through 6 configure the RS422/485’s termination setting by
Page 7 Page 8
providing parallel terminations. When these DIP-Switches are in the “MID” position (factory default), no termination is provided. Setting these DIP-Switches to the “H-T” position provides parallel termination. See the T ermination Table and Fig. 6 for details.
Note that all of the Mid Termination “MID/H-T” DIP-Switches on a RS422/485 need to be set to the same position, failure to do so will result in unpredictable behavior.

iConverter modules are hot-swappable and can be installed
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 panel thumb screw (attached to the module) to the chassis front.
3. Attach the serial ports via a DB-9 serial cable (or an open­end serial cable) to a serial RS-422 or RS-485 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 8790-1 matched with the 8791-1.
