GETTING STARTED
1.1 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 dual 9-36VDC or 36-75VDC power inputs
to a single input of 110-370VDC or 90-264VAC, 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 Ωterminations
•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.

Fiber repeater
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.

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.

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.

1.4 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.

2.3 Power Supply Connections
The Phillips Screw Terminal Block, located on the bottom of the unit, has Phillips screws
with compression plates, allowing either bare wire connections or crimped terminal lugs.
The use of #6 size ring lugs is recommended to ensure secure and reliable connections
under severe shock or vibration. The terminal block comes with a safety cover which
must be removed before connecting any wires. This cover must be re-attached after
wiring to ensure personnel safety.
The iSC2F supports a single power supply (PWR1) with 4 options:
1. LV: Dual Input 9-36VDC
2. MV: Dual Input Supply 36-75VDC
3. HV: Single universal Input 110-370VDC
4. HV: Single universal Input 90-264VAC.

3 PWR1 (N) – Neutral Connect to the Neutral of the DC power supply 1 or
(Neutral) terminal of an AC power source.
4 G – Chassis Ground
Connected to the ground bus for DC inputs or Safety
Ground terminal for AC Units. Chassis Ground
connects to both power supply surge grounds via a
removable jumper.
Note:
Options 1,2, and 3 don’t include terminal blocks. The DV power connection should be done
based on the diagram of the supplied chassis.
Power Supply Connection
Chassis Ground Connection
The iSC2F chassis ground connection, located next to the terminal block, uses a #6-32
Screw. We recommend terminating the ground connection using a #6 ring lug, and a torque
setting of 15 in.lbs (1.7Nm).
100-240VAC rated equipment: A 250VAC appropriately rated circuit breaker must be
installed.
Equipment must be installed according to the applicable country wiring codes.
110-370VDC rated equipment: A 370VDC appropriately rated circuit breaker must be
installed.
A circuit breaker is not required for DC power supply voltages of 9-48VDC.
Equipment must be installed according to the applicable country wiring codes.

Hardware Installation
The ISC2F is designed for maximum mounting and display flexibility. It can be equipped with
connectors that allow it to be installed in a DIN rail.
3.1 DIN Rail Installation
For DIN rail installations, the ISC2F can be equipped with a DIN rail bracket pre-installed
on the back of the chassis. The bracket allows the device to be slid onto a standard 35
mm (1.4 in) DIN rail.
To mount the device to a DIN rail, perform the following:
1. Align the slot in the bracket with the DIN rail.
2. Pull the release on the bracket down and slide the device onto the DIN rail. If
necessary, use a screw driver to unlock the release. Let go of the release to lock the
device in position.
