FIM-S222

FIM-S222

Optical Fiber Interface

For use with Eclipse HX Digital Matrix systems

Interfaces with one or two digital matrix panels

Highly secure connections

24-bit digital DEMUX

48kHz audio sampling rate

Sends and receives RS-422 control data

Flat frequency response up to 20kHz, S/N >80dB

Up to 20km (12 miles) range with fiber using single mode

Up to 5km (3 miles) using multi-mode fiber

Works in demanding environmental conditions

RJ45 connectors for direct connection with matrix panels, frames and interfaces

Can be used to extend any line level 4-wire audio signal / RS-422 signal

Can be used with the earlier FIM-102D but the audio will require 5dB of gain.

Features and/or Benefits

Secure and Reliable Interfacing

Two FIM-S222 interfaces are used for connecting a matrix frame to a remotely located user panel over fiber. For each connection between the frame and interface, a port is connected to one of the two matrix connectors on the FIM-S222 using the RJ45 connectors and 4-pair CAT5 cable. At the other end, each panel is connected to one of the port connectors on the second FIM-S222 using the same cabling. Once connected, the matrix frame can see the user panels as if they were directly connected via CAT5 cable.

High-Speed Audio Stream

The FIM-S222 provides two channels of any line level audio signal plus serial RS-422 data on a single pair of fiber. The consolidated signal is sent as a 24-bit digital stream through the outgoing fiber. The incoming data from the panel is decoded by the interface and is sent to the correct RJ45 connector and then back to the matrix frame. The process is reversed by the FIM-S222 at the user panel. High speed analog-to-digital and digital-to-analog converters are present on each audio channel.
