GETTING STARTED

Introduction

The iSC2F is a cost-effective single serial media converter solution for the conversion between serial RS232/RS485/RS422 interfaces and optical fiber. The iSC2F has been designed for power substation applications and rolling stock applications and is fully compliant with the IEC 61850-3 and IEEE 1613 standards.
The iSC2F accepts a wide input voltage range from single input of 11-36VDC (Opr), 24VDC (Nom); 36-75VDC (Opr), 48VDC (Nom); or single input 88-300VDC (Opr), 100-240VDC (Nom); or 85-264VAC (Opr) 50/60Hz, 100-240VAC (Nom), which makes it suitable for harsh operating environment. These features combined with a wide operating temperature of -40°C to 85°C help protect mission- critical applications from network interruptions or temporary malfunctions.

The iSC2F supports the following functions:

• Two-wire RS232 compliant (TX, RX)
• Two-wire RS485 half-duplex compliant (D+, D-)
• Four-wire RS485/422 full-duplex compliant (TX+, TX-, RX+, RX-)
• Switch selectable 120  terminations
• Up to 5 km multimode fiber
• Selectable Fiber Repeater Mode (fiber in -> fiber out)
• TX/RX LED indicators on RS232/485/422 Traffic
• Configurable RS485 half-duplex turn-around time
• 1200-115200 baud supported

The ISC2F is equipped to provide conversion from serial (RS232, RS485, or RS422) to fiber optics or between serial standards (RS232 to RS485 / RS422).

Serial to fiber optical conversion connections can be:

• Point-to-Point
• Fiber Repeater Mode
• Standard Serial Connection

By using the DIP switches, iSC2F can be used in the following operating modes.

Configuring the Device
The ISC2F can be configured using the Mode DIP switch located on the right side off the enclosure. Use the DIP switch to change the operating mode of the ISC2F.

The configuration settings are as follows:

Switch| ON| OFF|

---|---|---|---
1| RS232 to fiber| RS485/422 to fiber
2| RS232-to-RS485/422

conversion enabled

| RS232-to-RS485/422

conversion disabled

3| Full-duplex| Half-duplex (RS485 only)
4| 120 Ω terminations

enabled

| No 120Ω termination
5| Fiber repeater enabled| Fiber repeater disabled
6| 1200 – 2400 baud| n/a
7| 4800 – 9600 baud| n/a
8| 14400 – 19200 baud| n/a

baud

| n/a

Serial-to-Fiber Conversion—Point-to-Point

1. RS232 device
2. iSC2F
3. RS485 Device/ Network

Note that the distance between the two ISC2F devices should be less than 5 km (3.1 mi).

RS232 Device

Note : Position 3 applies to RS485 only.

RS422/RS485 Device

In this mode, serial data is converted directly into light signal and transmitted over multi-mode fiber optics. The serial standard is selected by Position 1 of the DIP switches: OFF (default) is for RS485/RS422, and ON is for RS232. Position 2 should be OFF for serial to fiber conversion. Position 6-10 should be configured if RS485 communications are used, to have the appropriate turn-around timer shown below selected. Positions 6-10 do not impact communications in full-duplex mode.

Fiber Repeater Mode

When a distance that is more than 5 km (3.1 mi) has to be supported, iSC2F must be used in Fiber Repeater mode. This mode supports extended distance between serial devices.

1. RS232 device
2. iSC2F
3. RS485 Device/ Network

The repeat function will optically re-transmit any data received on the optical receiver, in addition to any connected serial devices. As a result, any data transmitted from the master, will be re-transmitted optically to the slave. In this case, the distance between master and slave can be extended over the 5 km (3.1 mi).
This topology can be used for RS232, RS485 or RS422. In all cases, all repeater devices should have the repeat function—DIP position 5 ON.

Serial Standard Conversion

1. RS232 device
2. iSC2F
3. RS485 Device/ Network

In this mode of operation, RS232 voltage levels are converted to the appropriate RS485 or RS422 signaling levels depending on the DIP switch configuration. In this mode of operation position 2 of the DIP switches must be in the ON position when operation position of switch 1 is OFF.
Position 6 – 10 of the DIP switches must reflect the proper operating baud rate.

NOTE

In this mode of operation, no isolation is provided between RS232 device and the RS485/422
network– both devices share the same common terminal. It should be noted that the common terminal on RS232 devices is connected to ground. In some instances (i.e. when connecting to large RS485 networks), it may be preferential for the user to leave the RS485/RS422 shield terminal unconnected to the ISC2F in this mode.

Communication Ports

The iSC2F can be equipped with various types of communication ports to enhance its abilities and performance. To determine which ports are equipped on the device, refer to the factory data file available in specification.

Fiber Optic Ports

Fiber optic ports are available with ST (Straight Tip) connectors. Make sure the Transmit (Tx) and Receive (Rx) connections of each port are properly connected and matched to establish a proper link.

Laser Radiation – IEC 60825-1 Clause 7.2-7.7

Caution: Laser

This product contains a laser system and is classified as a CLASS 1 LASER PRODUCT. Use of controls and adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

General Fiber Optics Cables Handling Instruction

• Wear finger cots or gloves. Your hands may look clean, but dirt and oils on them can damage the fiber and contaminate connectors.
• Never use the fiber pigtail to pick up or support the weight of the device. Keep both the device and the optical connector together in your hand(s).
• The fiber is made of a very pure expensive glass. Treat it with the same care that would be used when handling expensive crystal glass.
• Do not allow kinks or knots to develop in the fiber. Do not pull on the fiber when kinks or knots are present. Pulling will only cause knots, kinks, and curls to tighten and exceed the minimum bend radius.
• Always use the correct tools for stripping and cleaving the fiber. It will save time and reduce breakage caused by scratches.
• Follow all ESD precautions.

Serial Terminal

The ISC2F is equipped with a seven-terminal Phoenix-style connector. This connector can accommodate one RS232 connection, and one RS485/422 connection. The following is the pin-out for the serial terminal:

Pin #| Signal|
