The RS-449 specification, also known as EIA-449 or TIA-449, defines the functional and mechanical characteristics of the interface between data terminal equipment, typically a computer, and data communications equipment, typically a modem or terminal server.

RS-449 governs the mechanical and electrical characteristics of the interface between data termi nal equipment (DTE) and data circuit-terminating equipment (DCE).

2022年6月6日 · RS449 is a high speed digital interface - unlike RS232 which uses signals with reference to ground, RS449 V.11 receivers look for the difference between two wires.

2018年11月13日 · Alternatively called the EIA/TIA-449, the RS-449 is short for Recommended Standard-449. It is a data standard that specifies the functional and mechanical characteristics of the interconnection between DTE (Data Terminal Equipment) and complying EIA (Electronic Industries Alliance) electronic standards RS-422 and RS-423 .

This manual contains descriptions, setup and operating instructions, specifications, maintenance, and service infor-mation for the TTC (Telecommunications Techniques Cor-poration) Model 41400 RS-449/530/MIL Data Interface.

RS-449 and its com­ panion standards were developed to permit an or­ • RS-449 specifies a different interface connector derly transition from existing equipment using RS- size and latching arrangement.

RS-449 is a serial communications standard that defines the interface between data terminal equipment (DTE) and data communications equipment (DCE). The standard is also known as EIA-449 or TIA-449.

2011年9月21日 · This chipset forms a complete software-selectable multiprotocol data terminal equipment (DTE) or data communications equipment (DCE) interface port that supports the V.28 (RS-232), V.10 (RS-423) V.11 (RS-449/V.36, EIA-530, EIA-530A, and X.21), and V.35 protocols.

The RS stands for recommended standard as defined by the ERA (Electronics Industry Association). People mostly use names like RS-232 and Rs-422 to identify the type of serial ports on a computer, or the cables that connect them. “Ah, …

La especificación RS-449, también conocida como EIA-449 o TIA-449, define las características funcionales y mecánicas de la interfaz. entre un equipo terminal de datos, típicamente un ordenador, y un equipo de comunicaciones de datos, típicamente un módem o servidor terminal.
