CMU 100 - 4 Channels Multimode Fiber Optic to RS232

3 4 CHANNELS MULTIMODE FIBER OPTIC TO

RS232 CONVERTER

3.1 DESCRIPTION

This device contains four full duplex 820 nm wave lenght multimode fiber optic and four RS232

interface. Data is send from one fiber optic to one RS232 port and vice versa. Device has four

independent channels.

Wide power supply voltage allows connection to all common station batteries. Additionaly it can

be also connected to standard AC voltages.

This device is intended for use in cubicles and cabinets in all kinds of power production,

transmission and distribution stations. It requires no maintenace. All normaly used connectors,

switches and light indicators are accessed at the front side of the device. One light indicator

indicates power supply voltage, others indicate communication transfer.

Fiber optic communication allows longer distances between devices without electromagnetic

disturbances. Fiber optic logic can be set to positive or negative logic for transmitter and receiver

separatedly. They can be set by DIP switch at the front side of the communication interface.

3.2 TYPICAL APPLICATIONS

Typical application is allowing four pairs of devices with RS232 port, communicating between

one another, without electromagnetic disturbances.
