I actually used a little light bar I have that has 3 12V LED assemblies on
it. I ended up using this after my resistor decade box died on me and I
couldn't find a 500 Ohm resistor. :)
I used an LED to watch the output on the 1488.
With an appropriate current-limiting resistor I would assume?
The LED lights
the instant I attach it to the output and doesn't flicker or
go out when I reboot the computer to make it send data out the port.
The little tester I have for rs232 stuff uses bi-color LEDs, makes it easier
to see what's going on.
Could be, I've certainly replaced my share of
those. And put sockets in
while I was at it. :-) Just make sure it's getting the proper power
supplies, as if one or both of them are missing you won't see proper output
then, either.
I did check the power first. :) 12V like it's supposed to be. If I have
to pull the board, I'll certainly put in a socket. :)
