You can find USB-AFP8550 Cable, but some are 8Pin, and other is 4pin, what’s the difference?
8pin is Orginal, Plug 4pin not, they all can used for Panasonic PLC, but 8pin is well
4 Pin Disadvantage
1, easy damage plc port, can’t aim at the port easily
2, easy make the pin bent or broken
3, to some extent, will cause short and damage to PLC
8 Pin
1, original plug, with locating device, easy plug and unplug
2, nickel plated the pin, anti-oxidant
3, circuit signal followed standard RS422 non-resistance conversion
