InLine 68889J RJ45 Grey cable adapter

The adapter features a metal-coated plastic housing with an RJ45 socket on one end and a 25-pin SubD plug on the other. The SubD pins are not fixed, allowing the user to assign signals freely for custom serial or control connections, for example when programming routers or ISDN devices via a serial interface. The compact, grey InLine accessory is intended to provide a simple interface conversion between RJ45 cabling and a SubD-25 connection.

Advantages

The metal-coated plastic case offers mechanical protection and a neutral appearance while keeping the adapter lightweight. The user-definable SubD pinout allows flexible use in a range of applications that require non-standard or custom wiring between RJ45 and 25-pin SubD connectors. The inline RJ45 socket supports standard RJ45 plugs for straightforward connection to network or serial adapters.

Key specifications

How to use

Connect an RJ45 plug into the RJ45 socket and insert the SubD-25 plug into the corresponding SubD receptacle on the target device. Assign the SubD pins according to the wiring diagram required by your equipment; since pins are not fixed, verify continuity and signal mapping with a multimeter or wiring tester before applying power or signaling. Use appropriate cable shielding and grounding practices when used in sensitive or noisy environments.

Recommendations

Verify the required pinout and signal levels for your device before making connections. Avoid forcing connectors; handle the adapter gently to prevent deformation of the SubD pins. For long-term or outdoor installations consider using dedicated, fixed-wiring adapters or sealed connectors.
