VC-Grid Safety and Installation Guide
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. Create a P3 video data link from a Martin P3™ system controller such as the P3-100™, P3-200™ or P3
PC™ to the P3 PowerPort 1500™ (see the products’ user manuals for details).
7. If required, continue the P3 video data link in a daisy-chain by connecting the P3 data throughput of one
P3 PowerPort 1500™ to the P3 data input of the next, as described in the P3 PowerPort 1500™ user
manual. You can connect up to fifty P3 PowerPort 1500s in a P3 data daisy-chain like this. If you need to
connect more than fifty, use an unmanaged Ethernet switch to split the P3 data link into branches, each
containing less than fifty P3 PowerPort 1500s.
8. Connect the P3 PowerPort 1500™ to AC mains power at 100 - 240 V, 50/60 Hz as described in its user
manual.
9. connect the P3 system controller to AC mains power and power the controller on.
You can now configure the system at the P3 controller. See”System setup” on page 17.
