RJ-45 to DB-9 Crossover Adapter
The Opengear 319015 is a 6-inch wired adapter that converts an RJ-45 female port to a 9-pin DB-9 female port. It is built for technicians who need to connect a network device or modem to a serial console or management interface. Copper conductors provide reliable signal continuity across the short link. The plastic housing protects the pinout during repeated insertions.
Thermals Noise and Power
The adapter draws no external power and generates no measurable heat during operation. Passive copper wiring means there are no active components to produce fan noise or electromagnetic interference. Power consumption is limited to the negligible signal current supplied by the connected ports. It adds no thermal load to the rack or enclosure where it is deployed.
Bundled Accessories and Software
The package contains the single crossover adapter only; no drivers, configuration utilities or mounting hardware are included. Because the device is purely passive, it requires no firmware updates or software installation to function. The crossover pinout is fixed at the factory, so the adapter works immediately when plugged into compatible RJ-45 and DB-9 ports. Buyers who need straight-through wiring or additional cable length must source a different adapter.

Questions about this item
How do I connect the 6-inch Opengear 319015 adapter between my network device and a DB-9 serial port?
Plug the RJ-45 female end into the network device or modem, then insert the DB-9 female end into the serial port; the crossover wiring handles the signal swap automatically.
What upkeep does the copper conductor and plastic housing need over time?
Inspect the connector pins for bent contacts or dust buildup; wipe the plastic housing with a dry cloth and reseat the adapter if the connection becomes intermittent.
What physical limit appears first when the adapter stays plugged in for long periods?
The 6-inch cable length restricts placement flexibility and can strain the ports if the linked equipment shifts or vibrates.
