EVE Energy EVE - cavo null modem - DB-9 (M) a DB-9 (M)

Connecting two legacy serial devices directly can be a headache—standard serial cables won't work because both ends expect to talk to a modem. This null modem cable crosses the transmit and receive lines, plus the handshaking signals, so two DTE devices like PCs, terminals, or industrial controllers can exchange data without extra adapters or gender changers.

Who is it for

IT technicians setting up headless servers or network gear via console ports, engineers configuring industrial automation equipment, and anyone who needs a reliable RS-232 crossover link between two computers or serial consoles. If your workflow still involves DB9 serial ports, this cable is your direct connection solution.

Main features

• Null modem wiring with crossed TX/RX, RTS/CTS, and DTR/DSR lines for full handshake support
• DB9 male to DB9 male connectors—fits standard serial ports on PCs, switches, and legacy equipment
• Foil and braid shielding blocks electromagnetic interference, ensuring clean signal integrity
• Durable PVC jacket and nickel-plated connectors resist corrosion and daily wear
• Supports data rates up to 115.2 kbps, ideal for console sessions and file transfers
• RoHS compliant construction with tinned copper conductors for long-term reliability

Tips

Before connecting, verify that both devices are configured for the same baud rate, parity, and stop bits. For long cable runs, keep the length under 15 metres to avoid signal degradation. If your devices have different gender ports, use a DB9 gender changer—but remember that adding adapters may affect signal quality.
