DTECH DB9 RS232 Serial Cable Male to Male Null Modem – Full Handshaking 7-Wire Crossover Cable for Data Communication (5ft, Black) DT-9007A

The DTECH DB9 RS232 Male to Male Null Modem Cable is a full-handshaking 7-wire crossover serial cable designed for reliable data communication between two RS-232 compatible devices.

Unlike straight-through serial cables, this null modem cable features cross-linked transmit and receive lines along with full hardware handshaking signals (RTS, CTS, DTR, DSR), making it ideal for applications that require stable and controlled serial data transfer.

Built with gold-plated pins, foil shielding, and screw-lock DB9 connectors, this cable ensures long-term durability and consistent performance in professional, industrial and legacy system environments. It is commonly used for connecting PCs, industrial controllers, printers, scanners, barcode readers, modems and factory test equipment.

⚠️ Important Notes:

• This is a null modem crossover cable, not a straight-through cable

• Not a VGA monitor cable (DB9 RS232 only)

• Designed for RS-232 serial communication
