The USB TTL cable is the cable with four pins including one pin with a triangle icon, please connect the USB TTL cable to the switch by console cable’s pin with a triangle in the place of the switch console pin with a circle icon (pin 1).

The USB TTL cable is as below image, please follow Zyxel’s console header pin definition: pin1 NA (with the circle mark), pin2 White (RX), pin3 Green (TX), pin4 Black (GND). Remember that don’t connect the red color pin to Zyxel’s console pin
