Termination Register

In case of communication through RS-422 channel, a termination register is to be connected to outside. As termination register protects the signal from the distortion by reflected wave in case of a long-distance communication, the register (1/2W) with the same value as the feature impedance of a cable is to be connected to the termination of a network. In case of recommended cable, connect the termination register of 120§Ù to both ends of the line.
