当没有数据传输时,信号保持在标记状态(逻辑“1”,负电压)。 注:DCE设备上的引脚2通常被标记为“接收数据”,尽管根据EIA232标准,它仍应被称为传输数据,因为数据被认为是去往远程DTE设备的。 Pin 3 - Received Data接收数据(RxD)当DTE设备从DCE设备接收数据时,此信号处于激活状态。当没有数据传输时,信号保持在...

传输距离短的另一原因是RS-232属单端信号传送,存在共地噪声和不能抑制共模干扰等问题,因此一般用于20m以内的通信。 由RS-232C标准规定在码元畸变小于4%的情况下,传输电缆长度应为50英尺,其实这个4%的码元畸变是很保守的,在实际应用中,约有99%的用户是按码元畸变10-20%的范围工作的,所以实际使用中距离会远超过50...

RS-232是最常见的串口,是大部分兼容Windows的桌面计算机的一个标准组件。 如今通过USB到RS-232转换器使用RS-232更为常见。 RS-232只允许每根线使用一个发送器和接收器。 RS-232也使用全双工双数方式。 NI某些RS-232板卡支持的波特率最高达1 Mb/s,但大部分设备限于115.2 kb/s及以下。
