INSTALLATION & WIRING
3
The DiGidot C4 is not designed to power the LED lights but only to transmit signal/data
to the LED lights/control IC's. Aside of the DiGidot C4, a seperate power supply with
properly rated output is required to power the LED lights. This is an example of how
the DiGidot C4 is connected to a LED strip and a power supply.
Data inputs/outputs
In this chapter we will go through various wiring diagrams, depending on the Input/Out-
put (I/O) configuration.
The DiGidot C4 is capable of sending different SPI protocols as well as using the same
ports for 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 in the user interface.
Go in the user interface or app to
NOTE: Make sure to select the correct device if you're using multiple devices and different
I/O setups. You can use the highlight button to identify your device to double check.
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 between the output port (D1-D4) and the LED luminaire, are no longer than 2
meters (6,5 ft).
In case of longer distances we advice to use range extending accessories (visit our
website www.digidot.eu for suitable accessories).
To avoid timing and synchronisation issues, all SPI signal cables must be equal in
length. In order to maintain good signal integrity, it's required to keep the wiring ca-
pacity as low as possible. Therefore the data wiring gauges for the D1-D4 output ports
should be kept between 0,3-0,5 mm2 (20-24 AWG).

This option shows four SPI Data only outputs. Each SPI Ground wire must be the same
length as the Data wires par output, to prevent timing issues.
