I install a card reader on my CX and i can't make the card motor to run. I have alle the fonctions available (cat-2) but if i put my calc in "program mode", load my program into "ram" from cat-1 Then insert the card, the motor don't take the card (it don't run)
I try others fonctions that write "CARD" on the LCD and when i enter the card nothing too; it's like the card reader don't detect the presence of the card
Perhaps it's more trivial; did i miss a command to do before using the card reader?
I opened the reader and the motor run free, the wheel is ok. I notice a kind of "LED" inside the reader is it an optical detection for the presence of the card?
Thank you for any help
