balanced voltages การใช้

• Balanced voltage between the three legs of power is important for operational life of the equipment receiving that power.
• The standard was written to be referenced by other standards that specify the complete DTE / DCE interface for applications which require a balanced voltage circuit to transmit data.
• RS-422, also known as ANSI / TIA / EIA-422-B, is a technical standard that specifies the electrical characteristics of the balanced voltage digital interface circuit.
