Another type of termination, ac coupled termination, adds a small capacitor in series with the termination resistor to eliminate the DC loading effect.
另一种类型终端电阻——AC耦合的终端电阻，增加一只小电容器串联在终端电阻上就消除了它的DC负载效应。
Terminal resistance method: to improve the quality of the communication on the 485 + and 485 - of the last 485 devices with a termination resistor of 120 ohms.
终端电阻法：在最后一台485设备的485 +和485-上并接接120欧姆的终端电阻来改进通讯质量。
