RS232 cable adapter No name KPO3432-1.8 — RS232 female socket to RJ45 plug, 1.8 m

Adapter cable converting a female RS232 (DB9) connection to an RJ45 plug. The No name KPO3432-1.8 cable is 1.8 m long and provides a fixed wired interface between devices with a DB9 serial port and equipment that uses an RJ45 console connector. It is intended for straightforward, point-to-point connection of serial devices without requiring additional converters or adapters.

Advantages

The adapter cable offers a compact, pre-wired solution to bridge DB9 RS232 ports and RJ45 console ports, eliminating the need for custom wiring. Its fixed 1.8 m length reduces cable clutter while providing sufficient reach for typical desktop and rack installations. The cable uses a female RS232 connector to preserve pinout compatibility with devices that expect a D-sub 9 female interface and a standard RJ45 plug for direct insertion into console ports.

Suitable for

• Connecting industrial controllers, PLCs and measurement equipment to consoles with RJ45 ports
• Linking routers, switches and network appliances to serial management ports
• Integrating point-of-sale (POS) terminals and receipt printers with networked controllers
• Temporary or permanent serial connections in service, configuration and diagnostics

Key specifications

• Interface: RS232 female (DB9) to RJ45 plug
• Cable length: 1.8 m
• Function: Serial data and control signal wiring for RS232 communication
• Connector gender: DB9 female, 8P8C (RJ45) plug
• Typical use environment: desktop, rack mount consoles, industrial control panels

How to use

Connect the DB9 female end to the RS232 male connector on the device or adapter cable assembly that requires a female serial interface. Insert the RJ45 plug into the target console or management port on the router, switch, POS controller or other equipment. After connection, configure baud rate, parity, data bits and stop bits on both ends to match the device settings and establish serial communication. No additional power is required for passive wiring; the cable carries standard RS232 signal levels only.

Usage recommendations

Verify pinout compatibility between the RS232 device and the RJ45 console specification used by the target equipment before installation. Use ferrite beads or routing practices to minimize electromagnetic interference in electrically noisy environments, and avoid excessive bending or tension on the cable to maintain reliable contacts.
