Recent Announcements

We have just completed a major update to our web site. You can now select a solution based on the interface requirements for your application. In almost all cases diagrams show a typical configuration. Specification sheets are accessible to provide the details to answer most questions on the VERSITRON products. Your feedback/comments on ease of use and quality of data provided would be of value to us. Our intent is to provide you with easy to use information that clearly shows the solutions we have available. We will be updating each of the specification sheets as we move forward.

Ethernet/Fast Ethernet
Fiber-Optic Media Converters

The M7233 and M7234 convert Ethernet/Fast Ethernet electrical signals into light signals for transmission over fiber-optic cable. They provide both cabling flexibility and network distance flexibility. A single LAN node can easily be extended to remote locations up to 2Km away on fiber-optic cable in full duplex configurations.

Future Products

A new video fiber-optic transmitter and receiver will be introduced in the summer of 1999. The transmitter will accept a standard NTSC or PAL video signal and transmit the signal over fiber-optic links to the receiver at distances up to 15 Km. Designed for CCTV applications, the new products will conform to applicable industry standards. A variety of enclosures/rack mount options will be available.

Technical Notes

Definition of Terms

Asynchronous – the data stream is broken down by random intervals. Each character has its own start bit and one or two stop bits. Sometimes called Start-Stop Transmission.

Synchronous – A continuous data stream of characters is synchronized to an internal or external clock reference. The clock maintains the exact timing interval to synchronize both the receive and the transmit functions to insure that the data is delivered at the specific intervals.

Isochronous – The data stream must be delivered within certain time constraints. An example would be audio synchronization with a video signal. IEEE 1394 supports isochronous delivery. Isochronous is not as rigid as synchronous; but not as lenient as synchronous operation.
