Serial Adapter DeLOCK DB9 Female to RJ45 Jack 64122

This adapter from DeLOCK converts a DB9 female serial connector to an RJ45 jack, enabling transmission of RS-232/422/485 serial signals over Cat.5 cabling. With a short cable length of 0.2 m, it provides a compact interface solution to connect devices such as printers, computers, gateways and POS systems to existing network-style cabling.

Advantages

Using Cat.5 cabling for serial connections improves transmission characteristics compared with standard RS-232 cables, allowing higher data rates and longer distances without additional signal amplification. The adapter is compact, easy to install, and compatible with common serial interfaces (DB9 to RJ45), making it suitable for adapting legacy serial equipment to structured cabling.

Suitable for

• Connecting printers and POS terminals to network-style cabling
• Linking computers, gateways and serial devices across Cat.5 infrastructure
• Extending RS-232/422/485 serial links using patch panels or Ethernet cabling

How to use

Connect the DB9 male plug from the serial device to the DB9 female side of the adapter, then insert a standard Cat.5 patch cable into the RJ45 jack to link to another adapter, patch panel or RJ45-equipped device. Ensure correct pinout and wiring are used for the targeted serial standard (RS-232/422/485) and verify connections before powering devices.

Recommendations

For reliable communication, use quality Cat.5 (or higher) cables and check pinout compatibility between connected adapters or devices. For long runs or high data rates, test the link and, if necessary, use signal repeaters or converters specific to the chosen serial protocol.
