Brand: DTECH

Simple Null Modem Serial Cable without handshaking, Male to Female (cross data lines TX, RX and GND signal ground): Direct communication 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, 5ft null serial male to female extender 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 DB9 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 serial null modem 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 9 Pin Serial Cable 5’ Male to Female 1 x Manual
