Question 1

My understanding is that this component has the ability to receive a signal like DMX and convert it to logic level, and it also has the ability to take logic level and send it out. Is it as simple as ...

Question 2

The lighting system of our church is in need of an update, so I'm shopping for parts including cables. At the moment, the lighting system uses a mix of audio cable and DMX cable, sometimes on the same ...

Question 3

I am very unsure about the position of the TVS diodes that are to protect lines A and B of my IC SN75176BP. Should I place them before my 10R series resistor or after the resistors to my IC?

Question 4

I am facing a problem. I have a DMX Splitter with several DMX outputs and each output uses an SMPC. A surge occurred and the SN75176BP IC burned out. The TVS diodes and 10-ohm series resistors that I ...

Question 5

I’m currently working on an ArtNet Node project using a Teensy 4.1 and aiming to build a 3 Universe ArtNet Node with Ethernet connectivity. Since I will be building the circuit on a breadboard I do ...

Question 6

I’m currently working on an ArtNet Node project using a Teensy 4.1 and aiming to build a 3 Universe ArtNet Node with Ethernet connectivity. The goal is to have four DMX outputs organized as follows: ...

Question 7

Im working on an Arduino project that involves receiving DMX with a MAX485 chip. The pinout of the chip has the 2 dmx pins labeled as A and B, but all the DMX pinouts have them labeled as + and -. ...

Question 8

I wanted to ask for help in researching appropriate Microcontrollers to create a Wireless Artnet/sACN Node for DMX communications with film and stage lighting Fixtures. The ultimate goal for the ...

Question 9

I'm trying to ID diodes on a board - the markings on the diodes are "BK 9EJ3D". I understand this is a TVS diode and it's being used to clamp RS485 differential pair to ground with a termination ...

Question 10

I have a DMX controller using a 3-pin connector (gnd, data+ and data-). I need to connect it to some cheap chinese DMX lights. The problem is that the lights are powered over the same 3 lines using a ...

Question 11

I'm using an ATMEGA328, with an external 20MHz crystal and fuses set by avrdude as -U lfuse:w:0x46:m -U hfuse:w:0xdf:m. I want to send DMX with it. Using the code ...

Question 12

I am using Infineon Dave v4.2.2. to program the XMC1200 boot kit with colour LED card to read a DMX input signal using a rotary dial. For those that don' know, Dave uses a simple UI with "apps" that ...

Question 13

I have a DIY project, with the aim of building an (LED-based) stage/theatre light from scratch. One of the challenges I've hit with this is getting DMX control to dim the LED. I spent some time ...

Question 14

I am creating a DMX receiver circuit. The dmx that is received from a controller (USB DMX dongle) is converted via a transceiver (SN75176BP) to a signal which can be understood by an ATMEGA328P. I ...

Question 15

I am trying to make a DMX splitter. Everything works now, but it would be somewhat useful to have notification LEDs, like in the example below. For the input I could use one LED, which I either ...
