Product Description

Belden Equivalent Cable # 3105A, 3106A, 3107A, 3108A, 3109A

Our cables are produced strictly under the same quality standards as Belden’s, from inside out. If you need wire and cable that requires Belden specifications but not the brand, we can provide the alternatives.

Application:

RS-485 signals are used in a wide range of computer and automation systems. In a computer system, SCSI-2 and SCSI-3 may use this specification to implement the physical layer for data transmission between a controller and a disk drive. RS-485 is used for low-speed data communications in commercial aircraft cabins' vehicle bus. It requires minimal wiring, and can share the wiring among several seats, reducing weight.

These are used in programmable logic controllers and on factory floors. RS-485 is used as the physical layer underlying many standard and proprietary automation protocols used to implement industrial control systems, including the most common versions of Modbus and Profibus. DH 485 is a proprietary communications protocol used by Allen-Bradley in their line of industrial control units. Utilizing a series of dedicated interface devices, it allows PCs and industrial controllers to communicate.[11] Since it is differential, it resists electromagnetic interference from motors and welding equipment.

In theatre and performance venues RS-485 networks are used to control lighting and other systems using the DMX512 protocol. RS-485 serves as physical layer for the AES3 digital audio interconnect.

RS-485 is also used in building automation as the simple bus wiring and long cable length is ideal for joining remote devices. It may be used to control video surveillance systems or to interconnect security control panels and devices such as access control card readers.

It is also used in Digital Command Control (DCC) for model railways. The external interface to the DCC command station is often RS-485 used by hand-held controllers[12] or for controlling the layout in a networked PC environment. 8P8C modular connectors are used in this case.
