Installation & Wiring; Data Inputs/Outputs - DiGidot C4 Extended Manual

INSTALLATION & WIRING
The DiGidot C4 is not designed to power the LED lights, but only to transmit signal/data to the LED
lights/control IC's. An additional external power supply with properly rated output capacity is
required to power the LED lights.

Data inputs/outputs

In this chapter we will go through various wiring diagrams, depending on the Input/Output (I/O)
configuration.
The DiGidot C4 is capable of sending different SPI protocols (only one protocol at simultaneously).
The input /output ports can also be configured as DMX inputs or outputs. This means that there are
many ways of connecting to the I/O ports. You can always verify your wiring in the 'How to connect'
box of the input/output configuration page in the user interface.
Go in the user interface or app to Home > S ettings > In/out configuration
TIP: Make sure to select the correct device if you're using multiple devices and different I/O
setups. You can use the highlight button
NOTE: There are some important principles when working with SPI signals.
In order to minimise the risk of data failures and to assure proper system functionality, the
data cables/wires between the output port (D1-D4) and the first LED luminaire/IC, should be no
longer than 2 meters (6.5 ft).
In case of longer distances, we advise to use range extending accessories (visit our website
www.digidot.eu for suitable accessories).
To avoid timing and synchronization issues, the SPI signal and ground wires that are running from
one DiGidot C4 to the LEDs must be equal in length per port. It's best to treat SPI signal and ground
wires always as a paired cable.
In order to maintain good signal integrity, it's required to keep the wiring capacity as low as possible.
Therefore, the data wiring gauges for the D1-D4 output ports should be kept between 0.3-0.5 mm
(20-24 AWG).
