Serial Interfaces Information

Modbus gateway serial interface image Serial interfaces are ports which allow connections to and communication with serial devices. Serial interfaces include a broad range of serial communications products, including personal computer (PC) ports, serial adapters, and serial boards. For information about an interface's serial protocol, network options, connectors, and form factor, please visit the Serial Adapters Selection Guide on Engineering360.

Interface Features

Serial interfaces may include one or several special features.

  • Interfaces with direct memory access (DMA) can bypass a computer's processor and communicate directly with its random access memory (RAM). This results in higher data transfer rates and reduced processor power.
  • Military interfaces conform with a specified military standard.
  • ESD protected devices have built in features to protect against electrostatic discharge (ESD), which can interfere with communication signals and damage hardware.
  • Plug and play interfaces attempt to auto-configure upon bootup.
  • Some interfaces feature indicators to signal power or transmission status.
