Product description

3.2

Method of operation

The ISD systems each comprise two units with different carrier frequencies. Each of the

components contains an optical data transmitter and receiver as well as a bidirectional,

electrical data interface (

Fig. 3-2

).

Fig.

3-2: Block diagram: operating principle of the ISD system

With one pair of devices, data can be transmitter and received simultaneously, i.e. data

transfer is possible in both directions. Different carrier frequencies prevent mutual optical

interference.

The data levels pending at the electrical interface of a transmitter (input) are transferred

optically to the opposite station using the FSK modulation method. The receivers on the

other side then reconvert the optical signals to electrical data levels and output them via

the electrical data interface (output).

If you are using the RS 485 interface, both units are ready to receive (RR) in the idle

state. The station which first receives data on the electrical interface determines the

direction of transmission until the data string has been transmitted. Both stations are

ready to receive again once transmission has been completed (automatic direction

switching). The data transfer rate must only be set on the ISD if you are using the

RS 485 interface.

The light path between the two units is monitored constantly. An LED on the front of each

unit signals interruptions in the light path and inadequate reception conditions. A

switching output, which is active when the light path is unobstructed (free), is provided in

addition to the LED.

Each of the device units in the ISD 230 system is also equipped with a switching output

which is deactivated under poor transmission conditions (e.g. lenses contaminated). The

transmitter on every unit can be deactivated via a switching input.
