Phone Central sensor makes you feel like a telephone switchboard operator. Connect two rows with the cables to trigger this sensor.
The maximum load of the feeback connector is 50 mA. If you want to connect something with a higher current load, connect an external power supply - then the maximum load is 1A.
Connect ports from both sides of the Phone Central sensor using the jack cables. Set them in a way that will solve this puzzle. Note that connecting two ports from one side won’t do anything.
Unscrew the back of the Phone Central sensor. Connect the control box inside to the Universal puzzle controller via included Ethernet cable.
Connect the Universal puzzle controller to a power supply.
Press the teaching button on the control box inside. From now on, every time the cables are plugged in this way, the Phone Central sensor will be triggered.
