To create a DMX-controlled installation that draws DC power from a generic 48 VDC PSU:
1. See Figure 8 on page 18 for an overview of this type of installation.
2. Make sure that no devices in the installation can be connected to AC mains power until all installation
work is complete.
3. Read “Safety Information” on page 4 and “Precautions to avoid damage” on page 7.
4. Connect VC-Grids together in chains using Martin hybrid PCB-to-PCB cables (see ”VC-Grid to VC-Grid
link cables” on page 30). Connect each cable from the THRU connector on one VC-Grid to the IN
connector on the next VC-Grid.
Warning! Check the PSU’s DC output power rating in watts and the power consumption figures in watts
for VC-Grid modules given in Table 3 on page 6. Do not create a chain of VC-Grid modules that will
exceed the power rating of the DC output on the PSU. Even if the PSU’s DC output power rating would
be high enough, do not create a chain of VC-Grids that contains more than the maximum permitted
number per chain given in Table 3 on page 6.
5. See Figure 9. Connect a Martin hybrid-to-PCB adapter cable (P/N 91616035) to the first VC-Grid of
each chain.
6. If necessary, you can extend the hybrid link cable run by connecting a Martin 4-pin XLR hybrid extension
cable to the Hybrid-to-PCB adapter cable. Suitable extension cables are available from Martin in various
lengths. See ”Extension cables” on page 30.
7. See Figure 9. If the PSU does not have constant overcurrent protection that will limit current to 8 A on
the DC output used, install an inline fuseholder with a 7.5 A or 8 A fuse on the white (+ve) power wire of
a Martin hybrid lead-in cable (P/N 91616037). A 30 amp automotive-type inline fuseholder with a 7.5 A
blade fuse can be used. Connect the power wires on the lead-in cable to a DC output on the PSU.
Connect the white wire to positive (+ve) and the black wire to negative (-ve).
8. Connect the 4-pin female XLR connector on the hybrid lead-in cable to the 4-pin male connector on the
hybrid-to-PCB adapter cable (or on the hybrid extension cable, if you have extended the hybrid link).
9. Connect the 5-pin male XLR connector on the hybrid lead-in cable to a DMX link that carries a DMX
signal from an RDM-compliant DMX controller.
10. Apply AC mains power to the external PSU.
11. Apply AC mains power to the DMX controller.
You can now configure the system. See ”System setup”on page 21.
