The contributor’s company received a shipment of output cables that, due to being “keyed,” had compatibility issues with some older units. He wrote to the factory and asked why they changed their system to one that apparently doesn’t work a lot of the time. He received this response:

Dear Adam,

Thanks for your mail.

We need to make this output keyed, for some end user will put cable in wrong slut.

Also if it happened that the cable just fitting in but there will be no funcation by this connection then it will caused some time to explain.

Pleas feel confort about this.

Best Regards,
