CONNECTING THE TERMINATION RESISTOR AND DIODE

A resistor is inserted for line’s impedance matching 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 for the communications system.

INSTALLATION AND EXTERNAL CONNECTION

BYPASS DIODE CONNECTION

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