Model 4137 Interface Converter Application:

The HP VersaLink Fiber to RS232 Converters are used to connect fiber optic linked Video Lottery Terminals to a controller having an RS232 interface port. While RS232 is a versatile communication standard, conversion to a fiber optic communication standard also allows data transmission that is no longer susceptible to electrostatic or electromagnetic fields. Additionally, the ports of the connected terminals are protected from damage by potential differences (ground variations) that often exist between them.


The illustration shows a Controller connected to the Model 4137 RJ45 port and Video Gaming Machines linked to the HP/Agilent Versatile Link connectors via HP Versatile Link Plastic Core Cables.
