DTECH 15ft DB9 RS232 Female to Female Null Modem Cable Serial Cord Simple Cross TX RX line Crossover for Computer Switch Laptop Router Data Communication (15 Feet, Black)

Simple Null Modem Cable without handshaking, RS232 Female to Female Extension Cord (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, 15 foot 9 pin serial cable 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 female 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 cross 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 RS 232 serial communication data adapter. Connectors: DB9 to DB9 Female to Female Pinout Configuration: Basic crossover of TX and RX lines, suitable for simple data transfer B9 cable Diameter: 6mm DWire Gauge: 30 AWG What’s Included: 1 x 15 ft Serial Cable Female to Female
