E65 Bus Systems

The layout of the ISIS takes the form of a star pattern. The Safety Information Module (SIM)

is at the centre of the system. Arranged radially around it are the satellite modules.

Each of the eleven satellites is connected to the SIM by a fibre-optic cable. Each of the

satellites contains a transmitter/receiver module.

The SIM contains twelve transmitter and receiver modules. All information from each of the

satellites is made available to every other satellite by the SIM. Each individual fibre-optic

cable in the

byteflight

bus system is used for bi-directional data transmission.

Function

Transmitter/Receiver Module (SE)

The transmitter/receiver module is a module that can convert electrical signals into optical

signals and transmit them via optical fibers. Every satellite has an electrical-optical

transmitter/ receiver module.

The transmitter/receiver modules are connected individually via the

byteflight

to the

Intelligent Star Coupler in the SIM. The SIM also contains a transmitter/receiver module for

each satellite.

All information transmitted across the

byteflight

is in the form of data telegrams sent by

means of light pulses. The transmitter/ receiver modules in the SIM receive the light pulses

from the various satellites. The Intelligent Star Coupler sends the data telegrams to all satel-

lites. Data transmission is possible in both directions.
