Abstract
A connector adaptor, alone or paired with a second connector adaptor and joined by a 4-pair CAT-5 type unshielded twisted pair cable, capable of transmitting synchronous data in RS232 type format between data transmissions equipment and data communications equipment, the adaptor having an equipment interface with greater than eight active pins and an RJ45 type interface, where eight of the active pins are connected directly to the eight contacts of the RJ45 type interface and at least one of the active pins is connected directly to another of the active pins in looped or shorted manner.
Claims6
A connector adapter for enabling synchronous serial data transmissions between DTE (data terminal equipment) and DCE (data communications equipment) over eight wires within unshielded twisted pair cable, said connector adapter comprising:
- an equipment interface having at least n pins, n being a number greater than eight, wherein one of said at least n equipment interface pins is a RTS (request-to-send) pin, and another one of said at least n equipment interface pins is a CTS (clear-to-send) pin and are adapted to transport n signals utilized by the DTE or the DCE during EIA/TIA-232 (Electronic-Industry-Alliance/Telecommunication-Industry-Association-232) synchronous serial communication;
- a RJ45 type connector interface having eight contacts each fixedly wired within said connector adapter to one of eight of the n equipment interface pins adapted to transport the n signals utilized by the DTE or DCE during EIA/TIA-232 synchronous serial communication;
- wherein the RTS pin is fixedly wired within the connector adapter to the CTS pin such that synchronous serial data communications may be transported across said connector adapter utilizing the eight equipment interface pins fixedly wired to the eight RJ45 type connector interface contacts.
