I sort-of gave up because of laziness but did do quite a bit of research and experimentation, including with a scope, beforehand. I do not recall anything about the signal being inverted but I was looking just at the IR-input, not something labelled NADLink.
I managed to get hold of circuit diagrams and components specs for both the SB3 and the relevant bit of my NAD amp (no, I cannot pass these on, so do not ask). Upon reviewing these it became clear why it was not working for me (and confirmed my experimental evidence): the SB3 component that drives the output is (effectively) quite high impedance and, the NAD input is relatively low impedance. The result is that the SB3's output does not have the guts to drive the NAD input. I was planning to use the RS232 serial port on the NAD as a power source for an small amplifier to overcome this but I never got around to it. In the end I just settled for attaching an IR LED (from some old remote) with a series resistor and taping this to the (optical) IR input on the AMP. All this was with an SB3. I did not move to using a Touch because of the restricted IRBlaster capabilities that it has - primarily with regard to arbitrary code passthrough. I think I looked at the Touch schematics and could not conclude whether it's output would be sufficiently low impedance to work un-amplified. ------------------------------------------------------------------------ awy's Profile: http://forums.slimdevices.com/member.php?userid=7480 View this thread: http://forums.slimdevices.com/showthread.php?t=39397 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/plugins
