## Long description

The Lindy 3m Null modem cable 31577 is a 3-metre serial cable with 9-pin D-sub connectors wired for null modem communication. It enables direct RS-232 serial data exchange between two devices without the need for a modem or intermediate adapter. The white jacket and flexible length make it suitable for desktop, industrial bench, or lab environments where reliable point-to-point serial links are required.
Advantages
This null modem cable provides a ready-made cross-over of the necessary transmit, receive and control lines to establish a direct serial connection. The 9-pin D-sub connectors ensure compatibility with equipment that uses standard DB9 serial ports. The 3 m length offers flexibility in device placement while maintaining signal integrity for typical serial communication speeds. The cable's construction and connector fit make installation straightforward and maintenance minimal.
Suitable for
 Connecting two computers or terminals directly for serial communication

Key specifications
 Cable type: null modem (crossed) serial cable
 Connector: 9-pin D-sub (DB9) male to 9-pin D-sub (DB9) male/female as appropriate for null modem wiring

How to use
Connect each DB9 connector to the serial port of the devices to be linked, ensuring firm seating of the screws to avoid intermittent contact. No additional adapters are required when both devices support DB9 serial ports and expect a null modem connection. Configure serial parameters (baud rate, parity, data bits, stop bits, flow control) on both devices to match each other before starting data transfer. If necessary, check device manuals for specific pinout expectations and adjust settings accordingly.
Usage recommendations
Use the Lindy 3m null modem cable in environments free from excessive electromagnetic interference for best performance. Avoid sharp bends and kinks in the cable; secure it with cable ties or clips to prevent strain on connectors. For long-term installations in harsh environments, verify connector retention and inspect the cable periodically for wear.
