Modem Cable ROLINE DB9 F - DB25 M 6 m

The ROLINE Modem Cable DB9 F to DB25 M, 6 m, is a serial adapter cable designed to connect a PC with a DB9 female serial port to a modem or device with a DB25 male connector. The grey cable provides reliable wired communication for legacy serial interfaces and supports stable data transfer between different RS‑232 devices.

Advantages

The connector housings are moulded with special plastic to reduce strain on the cable and prevent breaks. Bronze contacts with gold plating improve conductivity and corrosion resistance. Very good screening minimises data loss and protects against electromagnetic interference. Hand locking screws ensure a secure mechanical connection.

Suitable for

• Connecting a PC serial port (DB9 F) to a modem or device with a DB25 M serial port
• Legacy RS‑232 equipment in office or industrial settings
• Serial communication and configuration tasks where a DB9-to-DB25 adapter cable is required

Key specifications

• Connector A: DB9 female (9‑pole)
• Connector B: DB25 male (25‑pole)
• Cable length: 6 m
• Contact material: bronze with gold plating
• Connector housing: moulded plastic with strain relief
• Screening: high‑quality shielding for EMI protection
• Locking: hand tightening screws

How to use

Plug the DB9 female end into the PC serial port and the DB25 male end into the modem or target device. Tighten the hand screws to secure the connectors and prevent accidental disconnection. Verify serial port settings (baud rate, parity, data bits, stop bits) on both devices before initiating data transfer.

Usage recommendations

For reliable operation, avoid sharp bends and excessive pulling on the cable, and keep it away from strong electromagnetic sources where possible. Use the cable for RS‑232 compatible devices and verify pin assignments if custom wiring is required.
