RJ-11 connector is adopted for the connector of cashbox connecting line to connect with printer or customer display screen or cashbox card, and the shape is the same as that of ordinary telephone line connector. A total of 6 cores are allowed for RJ-11 head, of which the leftmost and rightmost cores are generally blank and invalid, so there are only 4 cores left in the middle. Only + and - lines are needed to drive the cash box, so some driving devices use 2 and 4 pins, and some use 3 and 5 pins as + and - poles. Please refer to the manual for specific connection method.
