Setup

The VC-Feeder automatically detects the LED display devices that are 
connected to it and the type of data signal (P3 or DMX/RDM) that is sent 
to it.

Setting up for P3 video display

When a Martin P3™ controller is connected to the data link and the 
installation is powered on, you can set up all the devices on the link for 
data display using the P3 controller. See the P3 controller user manual for 
details.

Setting up for DMX control

You can set up and control a VC-Feeder installation over the data link 
using an RDM-compatible DMX controller such as the Martin M1™ 
console or M-PC™ Windows application.

If individual DMX control of strings or groups of devices in the VC system 
is required, each VC-Feeder must be set up to receive instructions from 
the DMX controller on a DMX channel or group of DMX channels in the 
512 channels available in a DMX universe.

The DMX address, also known as the control address or start channel, is 
the first of these channels. Each group of devices uses this channel and 
the channels immediately above it to receive instructions.

The VC-Feeder uses the number of DMX channels required by the 
devices connected to it. For example, if a VC-Feeder has its DMX address 
set to 1 and you connect a string of 100 VC-Dots display devices (each 
using three DMX channels for RGB control) to the VC-Feeder, it will use 
channels 1 - 300. Channel 301 will be available for use as the DMX 
address for the next VC-Feeder.

If two or more VC-Feeder devices are set up with the same DMX address, 
they will receive the same instructions and behave identically. Setting up 
identical devices with the same address is an easy way to achieve 
synchronized action and can also be used as a troubleshooting tool.

DMX Addressing

Using an RDM-compliant DMX controller, you can communicate with the 
VC-Feeder devices on the data link via RDM. You can:
