SERIAL COMUNICATION INTERFACE

RS-232 and RS-485 are the serial interfaces commonly used when connecting devices to the computer.

RS-232 (ANSI/EIA-232 standard) is the serial connection found on IBM®.

RS-232 is limited to point-to-point connections between PC serial ports and devices.

In industrial environments, greater noise immunity, distance and multidrop capability are a big advantage.

These features are in RS-485 (EIA-485 Standard).

RS-485 is a major element and your gateway to the creation of device networks connected to e single serial port.

Connection of RS-232, RS-485 network via integrated optical interfaces

Optobox coupler is the easiest solution to exchange data between RS-232 or RS-485 network with star, ring or linear topology, acheaving an effective shield against electromagnetic interference.
Optobox provides an high failsafe capability thanks to the set-up of reduntant fiber optic cabling.
An hardware WD system checks the status of the optical path and a led display and a buzzer alert in case of invalid module status, such as:
An incorrect electrical or optical connection.Exceeded permissible transmission time for a user.

APPLICATION
Optical transmission technology, can be applied in every field of industrial automation.
- Interlinking of PLC systems with main frame computer.
- Distributed data acquisition systems.
- Building Automation.
