Equip DB9 to RJ45 adapter Female Serial Grey 72x33x16mm

The Equip 133388 DB9 to RJ45 adapter provides a female DB9 (serial) connector to interface with RJ45 cable connections. Its compact grey housing (72 x 33 x 16 mm) is intended for installation where a DB9 serial port must be converted to an RJ45 link, enabling the use of structured cabling or custom RJ45 wiring for serial communications. The adapter supports configurable serial pinouts so users can set pin assignments to match specific device requirements.

Advantages

The adapter offers a compact footprint and a female DB9 connector that simplifies linking legacy serial equipment to RJ45-based cabling. It supports customizable pin assignments, allowing flexible serial wiring configurations. The neutral grey casing is unobtrusive in mixed-equipment environments. Manufactured by EQUIP, the model 133388 is intended for reliable serial data transmission when using appropriate cables.

Suitable for

• Connecting DB9 (RS-232) devices to RJ45 cable runs
• Custom serial wiring and pinout adaptation
• Integrating legacy serial equipment into structured cabling systems
• Field setups where a compact DB9-to-RJ45 interface is required

How to use

Connect the female DB9 end to the serial device and attach an RJ45 cable to the RJ45 side; ensure the cable and any intermediate wiring match the required serial pinout. If a custom pin assignment is needed, set the adapter's pin configuration according to the device's wiring diagram before powering the equipment. Verify connections and signal levels (e.g., RS-232) are compatible with the connected devices.

Recommendations

Use appropriate RJ45 cabling and, if necessary, a pinout diagram to configure the adapter. Confirm serial interface voltage and signalling standards (for example RS-232) are compatible with the connected devices to avoid damage or communication errors.
