RS-485, also known as TIA-485(-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced , and multipoint systems are supported.
An 8 pin circular connector is used to connect (or daisy chain) AISG devices. AISG consortium has released C485 standard for this RS-485 connector. This standard specifies the mechanical dimensions of the connector more tightly than the previously used standard (IEC 60130-9 - Ed. 3.0 standard with screw-ring locking ring).
The use of any other XLR-style connector is prohibited. The three-pin XLR connector is commonly used for DMX512, on lighting and related control equipment, particularly at the budget/DJ end of the market. However, using three-pin XLR connectors for DMX512 is specifically prohibited by section 7.1.2 of the DMX512 standard.
USB-to-serial RS-232 adapters are often used with consumer, commercial and industrial applications and USB-to-serial RS-485/422 adapters are usually mainly used only with industrial applications. Currently, USB to TTL-level UART converters are used extensively by students and hobbyist as they can be directly interfaced to microcontrollers.
A DB-25 connector as described in the RS-232 standard Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data.
The connector between the vehicles is the 18-pole UIC connector. Since connectors are exposed and can oxidize, a current pulse is applied at connection establishment to evaporate the oxide layer, called fritting. The standard connector for the WTB nodes is a DIN 9 pin connector. The physical level uses RS-485 levels at 1 Mbit/s data rate.
The connector provides power to the keyboard on the outer two contacts and receives data signals on the inner pair. The cable between the computer and the keyboard is a coiled cord with an appearance very similar to a telephone handset cable. [11] The connector on the Amiga 1000 uses crossover wiring, similar to a telephone handset.
M12 A-coded 5-pin connector: For each connector size, the A-coding is the inspecific pinout variant and the only variant defined in varying numbers of pins. Ethernet cable with an M12 X-coded connector in one end and a modular connector in the other.
