Adapting to RS-485

The DB9F-to-5 screw terminal block adapter is a simple solution for connecting field wiring to DB9 connectors on USB serial adapters, Ethernet serial servers, and other Sealevel RS-485 products with a DB9M connector. The adapter works with two- and four-wire RS-485 networks and can be easily secured to the serial port with thumbscrews to prevent accidental disconnection.
