1 Overview
1.1 Introduction
The DMX-TR1 Xplorer can simultaneously transmit and receive DMX512 data. The
host board communicates with the DMX-TR1 Xplorer via SPI.
The DMX-TR1 Xplorer can be mounted on breadboards and development boards
supporting the MikroElektronika mikroBUS socket standard.

1.3 Pin Descriptions
Pin
Pin Description
Reset
Reset pin for XT1401A processor on DMX-TR1 Xplorer
0 = Resets XT1401A processor
Chip Select / Slave Select
Used by host in SPI communication to select slave to transmit to.
1 = DMX-TR1 Xplorer not selected
0 = DMX-TR1 Xplorer selected
SPI Master Clock In
Clock from host that drives SPI communication
SPI Slave Data Out
SPI data from DMX-TR1 Xplorer to host.
SPI Slave Data In
SPI data from host to DMX-TR1 Xplorer.
DMX Transmit Enable In
Controls if DMX-TR1 Xplorer is transmitting DMX data. If
disconnected this will be 1.
1 = DMX-TR1 Xplorer is transmitting DMX data out DMX Out +/-
0 = DMX512 transmission disabled
DMX Receive OK Out
Shows if DMX data received in DMX In +/- is correct
1 = Data is correctly being received into DMX In +/-
0 = No data into DMX In +/- for more than 1 second, or data is
incorrectly formatted (e.g. start code is not 0x00, Break signal too long
etc)
DMX Termination Switch
DMX Termination to stop noise. Used if this is the last device on
DMX Line.
Y = DMX line terminated here (this is the last device)
N = DMX line not terminated here
DMX Out +/-
DMX data transmitted by DMX-TR1 Xplorer
DMX In +/-
DMX data received by DMX-TR1 Xplorer

2 Getting Started
First, solder the headers onto the board, as shown in Figure 2-1.
Figure 2-1 Solder headers on DMX-TR1 Xplorer
Then connect the board into a mikroBUS slot on your development board, as shown
in Figure 2-2, and you’re off! The DMX-TR1 Xplorer will now receive and transmit DMX
data through the terminal block.
You can also mount the DMX-TR1 Xplorer onto a breadboard. Just make sure your
connections (such as SPI and power) are correct.
To communicate with the XT1401A processor on the DMX-TR1 Xplorer so you can
change data transmitted and read data received, check out the XT1401A-I/ST -
DMX512 Guide found at https://xtec-ind.com.
You’ll also find there code examples for many popular development boards, such as
Arduino and Raspberry Pi.
