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.
