Hi,
I am using argox as-8250 ps2 based barcode scanner . I can easily interface ps2 keyboard with 89c51 but with the same ps2 port when I am using barcode scanner than sometimes it gives output and sometimes it is not. actually whwn we press the switch of scanner it should show the continuous light but here in my case on pressing the switch for a sec it shows the light and without scanning it turned off. pls direct me . I am very near to result but I don't know what is the problem.
