The fiber optic systems DL-232 connect systems with a RS232 interface via fiber optics. The DL-232 allows communication via software-handshake (Xon/Xoff).
This innovative system allows creating optical point to point and bus structures.
The ruggedness to electrical and magnetic interferences, the potential separation of transmitter and receiver as well as ranges up to 40km between two fiber optic systems are important performance features of the transmission with POF, HCS and multimode or singlemode fiber optics.
LEDs and potential free contacts of a differential relay signalize defective states

LDM80
Signal Powered Fiber Optic Modem
DESCRIPTION
The LDM80 is a small, inexpensive fiber optic transmitter/receiver completely powered by the host RS-232 port. The enclosure for the LDM80 is a conductive shell which greatly reduces RF radiation and susceptibility. The rugged metal enclosure is small enough to mount on the back panel of typical computer equipment saving valuable desk and floor space. A pair of these units allows most RS-232C cable links to be replaced and extended with a duplex fiber optic cable. The normal 50-foot (15m) RS-232 limit may be extended to 2.2 miles (3.5 km). Fiber optic data communications provide complete EMI/RFI rejection, isolation, elimination of ground loops, and reduced error rates. Data security is enhanced by almost nonexistent electromagnetic emissions. The RS-232 connection is through male or female EIA 25-pin connectors. The fiber optic connection is through ST connectors.
The LDM80 is equivalent to a 3-wire, full duplex, RS-232 circuit. Handshake signals are locally connected as in Figure 1. Indicating LEDs come on during a "SPACE" on transmit or receive data. A TD/RD reversing DIP switch is provided for connection to DTE (Data Terminal Equipment) or DCE (Data Communication Equipment) ports.

RD300-OF & RD320-OF series
Serial RS232/RS422/RS485 to multimode or single mode fiber optic media converter.
Our devices features a self configuration mechanism based on a CPLD component freed you from the tiresome operation which consist in the serial parameters setup, product is "Plug & Play".
Using fiber optic enables to use a higher communication bandwidth while offering a total immunity against EMI/RFI interferences and an increased security as well.
The optical fibre still offers other advantages : use without risk in an explosive environment, no EMC emission, no ground loops, immunity against lightning and high voltage environments, they are finally lighter, less cumbersome, inert and corrosion resistant ...

Introduction
The ICF-1150 series support 2 serial ports, with a D-sub connector for RS-232 communication and a removable terminal block for RS-422 or RS-485 communication. The 3 ports (2 serial ports and one fiber port) are completely independent. When an ICF-1150 converter receives data from any one port, it will send the data out through the other 2 ports. For example, once the ICF-1150 converter receives a command from the remote master through the fiber port, it will convert the signal and send the command through the RS-232 and RS-422/485 ports at the same time. If the user is monitoring a system running on an RS-485 network, there is no need to use an additional RS-232 to RS-485 converter to connect the laptop computer’s serial port to the RS-485 bus.
Features
• RS-232, fiber, and RS-422/485 3-way communication
• Rotary switch to change the pull high/low resistor value
• Extend RS-232/422/485 transmission up to:
1. 40 km with single-mode
2. 5 km with multi-mode
• 3-way Galvanic Isolation (for "I" model only)
• -40 to 85°C wide temperature models available
• Class I, Div. II certification (Pending)

Fiber Optic Converters
Extend Communications Up to 9 Miles!
Any two pieces of asynchronous serial equipment can communicate at half or full duplex over two fibers at rates up to 460 kbps for RS-422/485 or 115.2 kbps for RS-232 with a pair of these converters. Fiber lines are inherently resistant to EMI/RFI and transient surges, so they are ideal for data communications near heavy electrical equipment and other electrical or radio interference.
Standards can be mixed and matched so RS-232 devices can be connected to RS-422/485 devices, replacing a converter and isolator. When working with RS-485 signals, B&B Electronics’ Automatic Send Data control eliminates the need for driver software. Serial connections are on terminal blocks; multimode fiber side has two ST connectors. Requires external power supply not included.
