RS-232C采用负逻辑，用-5～-15V表示逻辑状态“1”，用+5～+15V表示逻辑状态“0”。RS-232C的最大通信距离为15m，最高传输速率为20kb/s，只能进行一对一的通信。RS-232C可使用9针或25针的D型连接器，可编程序控制器一般使用9针的连接器，距离较近时只需要3根线（见，GND为信号地）。RS-232C使用单端驱动、单端接收的电路(见)，容易受到公共地线上的电位差和外部引入的干扰信号的影响。
Electronic computer shielded cable, choose high pressure polyethylene insulation, small dielectric constant use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure, with a small dielectric loss, transmit ability strong, good anti-jamming performance characteristics, can be reliably transmitted weak the analog signal or digital signal, can be widely used in electricity, metallurgy, petroleum, chemical, textile and other departments of detection and control computer system or automated devices, as well as general industrial computer. High-temperature F46 computer cable belong to one of the special cable, electronic computer system is in urgent need of modern industrial construction of form a complete set of products, it is widely used in energy industry, metallurgical industry and petrochemical industry and other industrial enterprises and scientific research department of the electronic computer, instruments and meters, all kinds of automatic detection equipment, and other information processing equipment signalling and the control system. Application: it is installed in indoor, cable trench, pipe and other places where high temperature resistance electrostatic shielding is required
