RJ45 serial connectors & adapters

This article summarizes the serial adapters available from Opengear.

In short, current Opengear models do not generally require an adapter to connect to RJ45 serial ports, and generally use the 319015 adapter to connect to DB9M serial ports.

Otherwise, these related articles will help you identify the appropriate adapter:

• Opengear RJ45 pinouts (past and present) with diagrams
• Per-model pinout support
• Serial cabling instructions for current models
• Adapters required to connect to specific equipment
