Page 6: Introduction
Introduction Thank you for selecting the Martin VC-Grid™. This compact LED-based display module is designed to integrate into a Martin P3™ video system to display video from a variety of sources, and it can also be controlled using DMX. Use of an RDM-compliant DMX controller such as the Martin M1™ or M-PC™ allows two-way communication and remote management of VC-Grid modules from the controller. -

Page 8: Physical Installation
Physical installation The VC-Grid can be installed in any orientation. The backs of modules are marked with arrows and the word TOP. To ensure the most evenly matched optical characteristics when viewing VC-Grids at an angle, install all modules with the arrows facing the same way. -
Page 9: System Installation
System installation Warning! Read “Safety Information” on page 4 of this manual carefully before installing a VC-Grid™ system. Warning! Connect the VC-Grid™ only to the devices specified in this manual and only using the Martin™ cables specified in this manual. Warning! Do not exceed the maximum numbers of devices that can be connected and maximum cable lengths specified in this manual and the manuals of the devices in the system. - Page 10 5. If necessary, extend the cable by connecting a Martin™ 4-pin XLR hybrid extension cable to the Hybrid-to-PCB adapter cable so that you can run the hybrid link to the P3 PowerPort 1500. Suitable extension cables are available from Martin™ in various lengths. See ”Extension cables” on page 27. 6.

Page 11: Installing A Dmx-Controlled System
Installing a DMX-controlled system In a DMX-controlled system, an RDM-compliant DMX lighting controller sends a DMX control data signal over a DMX link to the installation, and then over the hybrid link to the VC-Grids. The DMX link requires DMX cable. It can be maximum 300 m (1000 ft.) in length and must run in one single daisy-chain, but it can be extended or split into branches using an RDM-compliant amplifier/splitter such as the Martin RDM 5.5 Splitter™... - Page 12 Installing a DMX system using the Tripix Power IP66™ DMX/RDM Controller 48 VDC power DMX link (DMX cable) Hybrid (DC power and data) link DMX/RDM Splitter (if used) Tripix Power IP66 Tripix Power IP66 Hybrid lead-in Hybrid lead-in cable, Tripix cable, Tripix Power IP66 Power IP66...

Page 17: System Setup
System setup Warning! Before applying power to the VC-Grid: • Carefully review the safety information starting on page 4 • Check that the installation is safe and secure. Setting up for P3 display A Martin P3™ system allows video to be displayed on an installation that consists of or includes VC-Grid devices. - Page 18 If a VC-Grid module is set to individual pixel control (see “Setting modules to grouped or pixel control modes” on page 19), LEDs are given DMX addresses using a ‘left-to-right, then down’ numbering system (like the reading order you are using for the words on this page). For example, if one VC-Grid RGB module is set to pixel control and set to DMX address 1, each of the 64 LEDs will use 3 channels, and the module will use DMX channels 1 - 192 (Channel 1 -3 for the top-left pixel, channels 4 - 6 for the next pixel on the right etc.
- Page 19 Setting DMX Addresses See Figure 10. To set DMX addresses using the M-PC application, open the RDM View window and click on Scan to display a list of the elements in the installation. Click in the Address box for each VC-Grid module and enter the desired DMX address, then press the Enter key to store the DMX address for that module.
