Ethernet vs. Serial Radio Modem Considerations
• Ethernet offers the advantage of widespread acceptance and connectivity
and easier implementation.
• Ethernet ports are available on a wide variety of commercial and industrial
devices such as personal computers and programmable logic controllers.
Serial ports are becoming less common on both, particularly on
commercial devices, and may not be available without the use of an
external adapter.
• Serial may be required in applications where Ethernet is not available for
the devices already installed or to be added to the network.
• Ethernet allows connection to the Internet (for example, remote access and
email/text notifications).
• Ethernet supports multiple applications on the same network (for
example, web servers, video cameras, and data collection from multi-
vendor/protocol devices).
