Description

The DMX Relay Receiver is a DMX module that mounts four relays; they
can be individually controlled using a DMX master like TinkerKit!'s
DMX Master Shield. It requires 12V and each relay supports up to 220V
at 10A. A single master can control up to 512 receivers individually
(128 of these boards for example) sequentially connected.

The DMX Relay Receiver works also as a standalone USB board; in fact
it mounts a micro-usb connector and the same microcontroller as the
Arduino Leonardo.

RELAY OUTPUT

Where the high-voltages connections are made. Each Relay has three
outputs: the one in the middle is the common line, while the external
ones are normally-open and normally-closed. Refer to the relay
tutorial for more detailed information on hot to wire a relay
properly. BE ALWAYS SAFE WHEN WORKING WITH HIGH VOLTAGES, NEVER TOUCH
THIS PART OF THE BOARD WHEN THE HIGH VOLTAGE CURRENT IS RUNNING
THROUGH IT. ALWAYS DISCONNECT THE POWER FIRST!

2. DMX CONNECTIONS

Plug in here the wires from the Master Shield or another DMX Receiver.
The connections are easy, D+ goes to D+, D- to D- and GND to GND. For
the external power, the Relay module requires 12V.

3. ADDRESS

DMX works with one master and up to 128 receivers, all connected to a
single line. In order to send signals to the right output, each
receiver is identified by an address from 0 to 512.
Each receiver has an address that is set from this pin interface. The
address is expressed with a binary number where each pin correspond to
a digit.

If the pin is down that digit is 0, while if it's up it is 1. Mind
that the number is written from right to left; the most significant
digit is in fact on the far right. If you notice in the last example,
where we select an address with the number 20 (10100 in binary), we
start writing it from right to left. This address refers to the first
relay on the board (the one with the number 1 label), all the others
have addresses that are sequential to the first one.

e.g. if set the address of the board on 3 (101), if you want to turn
on the first relay you have to write:

DmxMaster.write(3,HIGH)

if you want to turn on the second:

DmxMaster.write(4,HIGH)

and so on. This means that if you have multiple DMX receivers, you
have to set their addresses with a gap of four numbers, in order to
have full control on all the modules on the board.

This is an example code used to control a DMX Relay Receiver with an
address of 5, we turn each relay on sequentially and then off
altogether. /* Relay sequential blink use this with a DMX Relay
Receiver (it works also with the MosFet) receiver. The address of the
board is set into the ADDRESS variable */ #include int ADDRESS
= 3; //the address of the board in decimal system void setup() {
/*set the max channel, in this way that the module doesn't have to
cycle through all the possible channels every time*/
DmxMaster.maxChannel(ADDRESS + 3); } void loop() { for (int i =
ADDRESS; i < ADDRESS + 4; i++) { DmxMaster.write(i, HIGH);
delay(1000); DmxMaster.write(i, LOW); } }
