From Patton Electronics Co.
For many years, serial interfaces such as current loop, RS-232, and RS-485 have been the preferred methods for industrial communications. Ethernet offers high reliability with the proven ability to adapt to changing environments, especially new types of media (coaxial cable and wireless transmission, for example). As Ethernet becomes the common interface for interconnection, it becomes natural to use this resource for all communications requirements. Adding voice communications capabilities, by either extending a telephone or offering a hot-line/party-line facility, can be as easy as plugging in a box and a handset.
While serial device networks offered a measured level of efficiency, their implementation was very inefficient. Often these networks were made up of many smaller networks.
Strings of similar equipment on single-network segments were laid on top of each other over the shop floor. Interestingly enough, this ad hoc architecture did provide a level of protection for the data on each network string. A new piece of gear on one network didn't affect any other network. If expansion was required, an element could be added without much trouble. If needed, a new string could be created. This practice made strings of equipment deterministic in their behavior at the expense of high operational and infrastructural overhead.

Bit Error Rate Testers
Bit error rate testers are devices or procedures that measure the bit error rate (BER) for a specific transmission.
Network switches connect network devices to host computers and allow a large number of devices to share a limited number of ports. They increase network capacity and speed by examining and filtering data packets. Switches also regenerate forwarded packets, reducing collision rates and permitting the use of additional nodes.
Network routers are protocol-dependent devices that connect subnetworks, or that break down a large network into smaller subnetworks.
Network gateways interconnect networks with different, incompatible communication protocols. They perform a Layer-7 protocol-conversion to translate one set of protocols into another (for example, from TCP/IP to SNA or from TCP/IP to X.25).
Serial Data Converters
Serial data converters are used to interconnect two different serial standards, such as RS232 to RS422, USB to RS232, etc.
