CONNECTING THE TERMINATION RESISTOR AND DIODE

Termination Resistor

A resistor is inserted for matching the line’s impedance to prevent distortion and reduction in RS-422 or RS-485 long distance data communications, which is referred to as termination resistor.

Note that termination resistors of lower than 90 accepted for the communications system.

INSTALLATION AND EXTERNAL CONNECTION

Bypass Diode Connection

If you connected an inductor (door lock or alarm device) to the output relay, there should occur a voltage surge while the inductor was between turning on and turning off. If you do not connect a bypass diode to the relay, the voltage surge will cause damage to the electric circuit of the controller. To reduce this surge, it is recommended to connect a bypass diode to the relay.
