The signal names match each other and connect pin for pin. The output signals on a DTE port are inputs to a DCE port, and output signals on a DCE port are inputs to a DTE port. They have the same signal names and PINs, but the signal flow is the opposite. RS-232 ports are of two types: Data Terminal Equipment (DTE) and Data Circuit Terminating Equipment (DCE).

Most Cisco routers natively support EIA/TIA RS-232 serial connections. RS-485 interfaces need only two wires for half-duplex communication. RS-485 interfaces support a multidrop, multimaster serial bus, which is an improvement over RS-422 interfaces. At reduced speed, it can operate at distances up to 1200 meters (0.75 mile). It can also be used for data rates up to 10 Mbps. RS-422 also supports multidrop, enabling multiple RS-422 devices to be connected on a single interface. At reduced speed, they can operate at distances up to 1500 meters (0.9 mile). RS-422 interfaces allow data rates up to 10 Mbps. It was intended to be a replacement for RS-232C. It offers much better speed and noise immunity, as well as longer cable length.
It comes in different physical layouts, including RJ45, DB9, and DB25. The maximum data rates on RS-232 can reach up to 20 Kbps.

RS-232 is by far the most popular interface used on devices such as PC COM ports as well as networking, consumer, and industrial devices for distances up to 15 meters (50 feet). Strangely overlooked in most operations, the physical dimensions of cybersecurity demand the devices we provide.Mini-USB or RJ45 – RS-232 with Cisco proprietary console pinoutĬommonly used asynchronous serial interfaces are of three types: EIA/TIA RS-232, RS-422, and RS-485. It is our mission to help you secure the open front door of the digital networks and information systems on which we all depend today. All the more reason to make the Smart Keeper DB9 Serial Port Lock part of your plan for data security.Ĭlick here to see how the Smart Keeper DB9 Serial Port Lock lines up as an integral part of the complete line of cybersecurity devices you can put to work immediately from Smart Keeper. The cost of any disruption in controls such as those might be calculated in dollars-per-second. The machine so governed could be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, or robot. Through them, digitized specs are used to control, automate, and monitor the movements of a machine. Computer-aided manufacturing (CAM) often depends on CNC – computer numerical control – and the connections that make these machines run to program are often made through DB9 serial port. Threats to your process, even downstream from your data systems, are still another reason to protect those open DB9 serial port. Research and practical experience alike confirm that casual contamination from “innocent” improvisation or insertion of personal devices, from known associates, can be just as serious a threat to the integrity and security of your data. It doesn’t take a sinister sabotage effort to corrupt that system, either. Yet, when a DB9 serial port is open, it is just as inviting for any kind of contamination that might threaten your vital data networks or information systems as an open USB or Firewire port might be. When you put a DB9 serial port in place, it stays in place. It is, perhaps, this “belt and suspenders” emphatic approach to making sure the connection stays connected that still sets the DB9 serial port apart from other configurations that have become more popular in current designs. Male and female shells are flanked by thumb screws that can secure the connection against torque, tug, or strain, holding the connection in-place. The DB9 serial port got its name from the D-shape of the frame or “shell” around the connection, the B designation of its size, and the nine pins arranged in two rows that form the basis of connection. The DB9 serial port is still an important interface for serial communication in many data networks and information systems, so making sure their legacy is not a legacy of insecurity is an important part of completing your cybersecurity perimeter. Still, they appear in the workplace commonly even now, because D-subminiature connectors – including the DB9 serial port – were a longtime standard for connecting controls such as keyboards, mice, and joysticks, as well as peripheral devices such as projectors and network connections.
