The RS-485 standard (also known as ANSI/TIA/EIA-485) was developed in the 1980s to allow a master device to communicate with multiple slave devices. RS-485 defines a method for serial transmission using differential signal lines shared by up to 32 devices. Its advantages over RS-232 include higher noise immunity, higher speed, (more...)
Recommended Standard 232 (RS-232) was introduced in the1960s by the telecommunications industry. It defines a simple method for serial communication between a Data Terminal Equipment (DTE) device, such as a computer, and a single Data Communication Equipment (DCE) device, such as a modem or computer peripheral. Originally managed by the Electronics Industry Association (EIA-232), (more...)
The Universal Serial Bus (USB) originated in 1996 as a way to connect peripherals, such printers and scanners, to a personal computer. Since that time, it has evolved into a broadly used interface on a wide variety of products. (more...)
Panel mount digital controllers are commonly used for process control. However, many digital panel meters (DPMs) can also perform process control functions. A panel meter is a good choice when advanced control functions, such as PID, are not required, and on/off or proportional control is sufficient. Why use a panel meter? (more...)
