1. Overview
1.1 Introduction
The FTDR-S2-WSB series Multi-Drop Self-Healing Ring Fiber Optic Modem interlinks with
RS232/RS422/2 wires RS485/4 wires RS485 interface devices over 2 single-mode optical
fiber cables. This product is intended for self-healing ring topologies. Our Multiple
Self-Healing Ring Configuration offers maximum reliability as it can recover simultaneous
faults or failures in two different locations. The Self-Healing Ring consists of two data paths,
Ring A and Ring B, with each data path running in an opposite direction to the other. Under
normal operation, only the primary data path (Ring A) is used, when there is a fault (cable
or failed device), the data path will turn around before it reaches the fault or failed unit and
use the secondary data path (Ring B) to complete the link. With this process, the data path
remains intact. The data communication protocol is transparent and compatible with all the
RS232/RS422/2 wires RS485/4 wires RS485 upper protocols.
The FTDR-S2-WSB series Fiber Optic Modem can be widely used, such as Industrial
Controls, Intelligent Transportation Systems (ITS), Industrial Networking, Supervisory
Control and Data (SCADA) and so on.

①The 2 wires RS485/4 wires RS485 output bus pull-up and pull-down resistance usually should be
switched on. But if there are several fiber transmitters or receivers, 2 wires RS485/4 wires RS485
output interfaces are connected together, only one of the 2 wires RS485/4 wires RS485 output Pull-up

②The terminators can be switched on or off according to the RS485 bus connection. When the fiber
transmitter or receiver is placed at the end point of bus, the terminators are usually switched on, but

DIP2 Switch setup table:
The master is typically the unit that is connected to the host computer/equipment. The
master switch determines the point in the ring where the data loop ends and is not
re-repeated around the ring. For example in a camera/telemetry scenario, the master would
be the unit connecting to the Matrix. The remaining nodes in the ring, with keyboards for
example, would be slaves.
DC or AC Power Supply between 12V and 24V can be used on this product.
•DC:
＋: +12VDC~+24VDC
－: Power Supply Ground
•AC:
There is no difference between ＋/－; the power supply can be connected into the
device directly.
