Connecting terminal resistors

Make sure to provide a terminal resistor at the end of each line.

In the case of one-pair wiring, connect a terminal resistor to the RDA-RDB signal

terminal of the communication equipment.

Use two terminal resistors of 110 Ω, 1/2 W.

Among the terminal resistors supplied with the communication equipment, select

ones with the color codes shown to the right.
