DMX or OK led

Message
Publicidad

Hello! Is it possible to connect a LED to the manolator interface? I'd like to signal different states of the interface... (for example: if led is blinking all is OK; if led is OFF no signal from PC; if led is ON signal too fast from pc. ect...)

Hello:

I think you can try it.

Cheers.

Hello:

Maybe you can add a led to the circuit but the easy way is to bild the two leds tester inside a conector to try not only the interface but also your dmx instalation.

It works as a end dmx end of line connector but instead one resistor it uses two resistors and two leds.

You can find the schematic in this forum (dont remember where) or here.

Re: DMX or OK led

Thankyou for the information and for the link you gave me!

This connector is very useful, but I'd like to do something more ingegnous: I thought to connect 2 leds to my interface.

1st led connected between +5V and pin 17 of 16F84/88; This led will blink every time DMX data will be sent to my implant.

2nd led connected between GND and pin 2 of 16F84/88; This led will blink every time DMX data will be loaded from PC to PIC.

What do you think about??

(both Leds must be High Efficiency and they need a 1Kohm resistor in series to limit the current)
