DTECH 6ft RS232 Null Modem Cable DB9 Male to Female Serial Extension Cord Simple Cross TX RX Line 2 Pin Crossed for Computer Switch Router Data Communication (6 Feet, Black)

Simple Null Modem Cable without handshaking, Serial Female to Male Extension Communication (cross data lines TX, RX and GND signal ground): transfer data between 2 Data Terminal Equipment DTE devices using RS-232 serial communication protocol. If you need a 3 wire null modem serial extension cable long enough to control the legacy equipment, 6ft 9 pin male to female serial adapter can extend original serial to serial cord. (Note: this male to female crossover cable work by only wiring the transmit and receive lines crossed - TX to RX, RX to TX; other control lines like RTS CTS are not cross-linked, not a loopback handshake null modem cable, neither a full handshake null modem cable.) For RS-232C devices serial console access:the proxySG, advanced secure gateway, content analysis, reporter, management center hardware devices, network equipment, etc. Black 9 pin serial cable male to female is with gold plated pins for superior corrosion resistance, ensuring a solid basic null modem cable connection. The connectors are equipped with a pair of thumbscrews for securing the plug to the female socket. DB9 RS232 cable is shielded with Foil-Al layer shielding as most crossover serial cables do, it fits for most of jobs. But if there are big mess of interference at your work area, you may need a special heavy duty DB9 cable that features copper braided + AL-foil double shielded layer. Not a 15 pin VGA cable that connects monitor to laptop, it's a DB9 female male cable that only works for RS 232 data communication. Connectors: DB9 to DB9 Male-Female Pinout Configuration: Basic crossover of TX and RX lines, suitable for simple data transfer DB9 cable Diameter: 6mm Extend a 9 pin serial male to male cable, or connect it to an old serial port device along with a USB to serial adapter What’s Included: 1 x RS-232C Serial Male to Female TX/RX crosslinked Cable
