Serial DB9 F/F Modem Cable 0.5 m, MEGA (MPN 81416), Black

Half-meter serial DB9 female-to-female modem cable by MEGA (81416) in black. This 0.5 m cable features DB9 female connectors on both ends and weighs approximately 91 g. It is designed for RS-232 serial connections between modems, routers, serial devices and legacy equipment, providing a reliable short-distance link for data transfer, device configuration and diagnostics.

Advantages

The female-to-female DB9 wiring supports direct connection between two PC serial ports or between serial devices without requiring gender adapters. The cable implements a null-modem style crossover of transmit and receive signals to prevent data conflicts between connected devices. Its compact 0.5 m length reduces clutter and signal degradation on short runs, while the standardized DB9 connector format ensures compatibility with a wide range of RS-232 equipment.

Suitable for

• Connecting two PC serial ports for direct data transfer
• Linking modems, routers and serial peripherals for configuration or diagnostics
• Short-distance RS-232 communications in workshops, labs or industrial control panels
• Legacy equipment connections where DB9 female ports are used

Key specifications

• Cable length: 0.5 m
• Connector type: DB9 female on both ends
• Color: Black
• Weight: approx. 91 g
• Interface standard: RS-232 serial

How to use

Plug each DB9 female connector onto the corresponding male DB9 port of the devices you want to link. Ensure both devices are powered off or in a safe configuration state before connecting. After physical connection, power on the devices and configure serial parameters (baud rate, parity, data bits, stop bits, and flow control) on both ends to match. Use the cable for short-range data transfer, device configuration, firmware updates or diagnostic sessions as required.

Usage recommendations

For reliable operation, keep the cable run short (this product is intended for short-distance connections). Verify serial settings on both devices and, if necessary, use appropriate terminal software or communication utilities for testing. Avoid routing the cable near high-voltage lines or strong electromagnetic sources to minimize interference.
