6ft null modem serial extension cable Male to Female 3 wire simple crossed without handshaking: connect 2 DTE devices with 9 pin 2 row COM port RS-232 compatible interface (NOT 15 pin 3 row VGA video) 9 pin serial cable male to female port cord is wired as DE9 simple null modem cord that 2-3 line are crosslinked (only TX/RX and signal ground wires connected); AL foil shielded crossover rs232 cable DB9 cable m/f adapter extender equipped with screws on each end to ensure an easy and solid connection for stable serial cross PC cable data communication 9 prong db9 rs232 serial cable：the wires inside are of 30AWG gauge and easy to solder to, and they connect to the pins in the order of the standard wire color code (6ft crossover serial cable, not VGA video cable) 6 feet long male to female RS232 cable for hooking router to laptop PC, desktop computer, RS232C switch hub to transfer file, share resource, direct serial communication link, debugging , testing 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
