Techniques to Protect your RS-232 Serial Connections RS-232 connections are an integral part of serial to Ethernet networks. Most Ethernet networks are exposed to harsh environments and cater to high traffic data transmission demands. Being an active part of Ethernet Networks, the RS-232 serial device and its connections are exposed to damaging parameters. Therefore, it requires protection against power issues. The chances of electrical hazards, device damage, and abrupt failure of the network might be inevitable, if the appropriate measures are not taken. This post discusses different techniques of protection of RS-232 cabling in electronic devices or serial to Ethernet networks.
Overview of RS-232 • • •
RS stands for Recommended Standard and 232 refers to TIA-232-F standards. The RS-232 cables connect DTE and DCE by using DB9 connectors. It is sensitive to electric surge and ground loop noise
