Serial Cable Moxa RJ45 (8-pin) - DB9(M) CBL-RJ45M9-150 1.5m

The Serial Cable Moxa RJ45 (8-pin) - DB9(M) CBL-RJ45M9-150 1.5m is a purpose-built connection cable for linking devices that use an 8-pin RJ45 serial connector to equipment with a male DB9 serial port. With a 1.5 metre length and a straightforward fixed wiring configuration, the cable suits equipment racks, consoles, industrial controllers and communication devices where a reliable serial link is required. The construction is intended to deliver consistent data transmission and withstand typical handling in professional and industrial settings.

Advantages

This Moxa cable provides a stable physical connection between RJ45 (8-pin) serial interfaces and DB9 male ports, reducing the need for adapters. The 1.5 m length offers flexibility for installation without excess slack, and the cable’s robust build is designed to hold up to repeated plug/unplug cycles and standard industrial use. Compatibility with common serial pinouts simplifies integration into existing setups.

Suitable for (tasks / use cases)

• Connecting network equipment consoles to management PCs or terminals
• Linking industrial controllers, PLCs or serial devices to computers
• Serial communication in racks and control cabinets with limited space
• Field service and maintenance tasks requiring a portable serial link

When it may not be suitable

This fixed-wiring cable is intended for RS-232-style serial connections between an 8-pin RJ45 and a male DB9. It may not suit environments that require shielded or special-purpose cables for high electromagnetic interference or extreme environmental protection. It is also not a replacement for USB, Ethernet, or other non-serial interface standards and will not provide protocol conversion beyond the physical connector wiring.

Key specifications

• Connector A: RJ45, 8-pin (serial pinout)
• Connector B: DB9 male
• Length: 1.5 m
• Cable type: fixed serial connection cable for RJ45-to-DB9
• Designed application: serial data transmission (RS-232/console usage)

How to use

Connect the RJ45 end to the device or console port that uses an 8-pin RJ45 serial connection, and plug the DB9 male connector into the corresponding DB9 female port on a PC, terminal or serial adapter. Ensure both devices are powered off or in a safe state before connecting if recommended by the device manufacturers. After physical connection, configure the communication parameters (baud rate, parity, data bits, stop bits and flow control) on both ends to match for successful serial communication.

What to consider before purchase

• Verify that your devices use the RJ45 8-pin serial pinout and a DB9 male/female pairing that match this cable’s wiring.
• Confirm that a 1.5 m length is sufficient for your installation routing and reach.
• Check whether additional shielding or environmental protection is required for your installation.

Recommendations

For reliable operation, route the cable away from high-voltage power lines and heavy electrical noise sources, secure connections to avoid strain on connectors, and match serial port settings on both devices. If you are uncertain about pinout compatibility, consult device documentation or technical support before use.
