摘要： An RS-232 transmitter apparatus includes first and second power supplies to respectively supply a first voltage and a second voltage which are based on the RS-232 standard and are different from each other; an input terminal to receive a signal from an external source; and a switching part to select the first power supply or the second power supply according to levels of the signal inputted through the input terminal so as to supply one of the first voltage and the second voltage. With this configuration, the present inputted through the input terminal provides an RS-232 transmitter apparatus which can perform RS-232 communication without an RS-232 transmitter IC including a charge pump, thereby reducing material cost.
摘要翻译： RS-232发送装置包括分别提供基于RS-232标准且彼此不同的第一电压和第二电压的第一和第二电源; 用于从外部源接收信号的输入端; 以及切换部，根据通过输入端子输入的信号的电平来选择第一电源或第二电源，以便提供第一电压和第二电压之一。通过这种配置，通过输入端子输入的现在提供了一种RS-232发送装置，其能够在不包括电荷泵的RS-232发送器IC的情况下执行RS-232通信，从而降低材料成本。
