SERIAL

- Do you need to transmit RS-232 over more then 400 meters

- RF noise and EMI cause the fault of the system?

- Is it impossible to ground both cable's ends?

...wouldn't a "self-installing" cable be great?





What if such a cable were also...



- immune to electromagnetic interferences, to guarantee the trasmission, always

- unaffected by ground loops, to ease the installation

- resilient to humidity, schocks and vibrations, in order to assure reliability and duration

- tailored for 150 m (1500 ft) transmission without repeaters...

...how would you like it?

RS-232 or RS-485 up to 150 meters?

It's easy... it's plastic fiber



The serial protocol RS-232, once commonly used by PCs, is still being employed in a number of applications: from process' control in factory automation to measures in anechoic room for CE certification, from access control to remote control of dome cameras in video surveillance systems.

In order to increase transmission distance, RS-485 converters are conventionally used, which require single - or double - shield cables to avoid RF noise.

Easing the installation and reducing costs is possible, while maintaining great performances: plastic fiber applied to RS-232 and RS-485 protocols gives many advantages.

- Ease of use: termination require less than 25 seconds and can be made with common tools. Plastic fiber tolerates misalignement of connectors, hence its operation is guaranteed.

- Small size: a single plastic fiber cable has a diameter of 2.2mm and fits into any conduit, reducing installation's costs. It's ideal for museums, houses, shops, churches and where laying cables or new conduits is impossible or too expensive.

- Standard compliancy: plastic fiber is made of insulating material and can share conduits with power lines, complying with the international standards (EIA/TIA 569, CENELEC EN 50174-2).

- Instant testing: no tester or special instrument is needed to check functionality: just look if light comes out of the cable.

- Immunity from interferences: plastic fiber is immune to RF noise irradiated by electrical cables, neon and antennas.

- Safety: unlike wireless systems which are unsafe at hardware MAC, level, plastic fiber can't be tapped into and the communication can't be easily interrupted. Plastic fiber doesn't emit radiations, whose "non-harmfulness" has to be proved.

- Cable grounding: plastic fiber needs no grounding, because it doesn't conduct current and acts as an opto-isolation device.

- Savings: plastic fiber transmits video up to 300m (1000 ft) without repeaters, saving the cost of new conduits and amplifiers/equalizers.

- Strength: plastic fiber cable tolerates bending radii less than 20mm, works from -40°C to +85°C and is guaranteed for a million bending cycles.

- Electrical insulation: plastic fiber doesn't conduct current and can be used in flammable or explosive environments, no more need for EX-D conduits or expensive antideflagration cables.

- Remote power supply: the hybrid cable HyPer, which contains two copper wires and two plastic fiber cables, allows simultaneous transmission of video and power supply.
