Καλώδιο null modem InLine DB9 υποδοχή θηλυκή / DB25 υποδοχή θηλυκή 2m μπεζ

The InLine null modem cable connects two PCs, notebooks or servers via their serial COM ports using a DB9 female to DB25 female wiring. With a length of 2 m and a beige jacket, the cable is intended for direct serial communication and compatible with devices that require a null modem pinout. Note: pay attention to the PIN assignment when installing.

Advantages

This null modem cable provides direct device-to-device serial communication without the need for modems or additional converters. The 2 m length offers moderate reach for typical desktop or rack environments. Connectors are standard DB9 (9-pin Sub D) and DB25 female, ensuring compatibility with legacy equipment that uses RS-232-style COM ports.

Suitable for

• Direct serial data exchange between two computers or servers
• Connecting legacy equipment that uses DB9 or DB25 COM ports
• System configuration, firmware updates or console access via serial ports

How to use

Plug the DB9 female end into the 9-pin serial COM port of one device and the DB25 female end into the 25-pin serial COM port of the other device. Ensure both devices are powered off or that their serial ports support hot-plugging before connecting. After physical connection, configure serial port parameters (baud rate, parity, data bits, stop bits, flow control) on both devices to match the communication settings required by your application. Verify the PIN assignment if communication fails.

Recommendations

Check device documentation for the correct pinout and RS-232 settings before use. Avoid routing the cable near strong electromagnetic sources to reduce interference, and secure connections to prevent accidental disconnection during data transfer.
