## Description

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.
