4.14.1 Mechanical installationMechanical installation
LEDkoLEDko EXT MEXT M may be hung from an appropriate structure in any position or on tripode. If
hanging the fixture from a lighting truss or similar, we recommend the use of an appropriate
clamp “AA”, as shown in the following diagram.
Warning!!Warning!!
Always ensure that your support structure
and fixing (bolts, clamps, etc…) are rated to
support the weight of the fixture.
4.24.2 Safety chainSafety chain
When hanging LEDkoLEDko EXT MEXT M it is recommended to use a safety chain, as required by current
legislation. The safety chain must pass through the handles of the unit and then attached to
the structure.
If using steel cables and chains not Coemar’s production, make sure they are suitable to support
the weight of the unit according to normative UL/ETL (required: the weight of 6 complete
devices for at least one hour).

Warning!!Warning!!
• The use of a thermal/magnetic circuit breaker is recommended. Strict adherence to
regulatory norms is strongly recommended.
•• LEDkoLEDko EXT MEXT M should not be powered through a dimmer as this may damage the internal
switching power supply.
• Prior to connecting the device to mains power, ensure that the mains characteristics are
within the recommended range for the use of LEDkoLEDko EXT MEXT M.
• All cabling and connections should be carried out by a suitably qualified personnel.

6.16.1 Control signal connection by XLR5 plugsControl signal connection by XLR5 plugs
The digital control signal is transmitted to the projector via a two pole cable screened as per
International standards for the transmission of DMX 512 data. The connection must be serial,
using connectors XLR5 male and female located on the back of LEDkoLEDko EXT MEXT M Series labelled
DMX512 IN e OUT (see diagram).
Connectors equipped on LEDkoLEDko EXT MEXT M are IP rated, which ensures protection against water
and dust. In order to keep this rating they must be connected exclusively to other IP rated
connectors.

8.18.1 Quick guide to menuQuick guide to menu
The LEDkoLEDko EXT MEXT M required RDM (Remote Device Management) to set up fixtures. Using
an RDM compliant DMX controller, you can communicate with all the fixtures on a data link
without needing to connect to each fixture individually. RDM lets you set the DMX addresses
of all the fixtures on the link, carry out fixture configuration and retrieve fixture data including
details of any error that has been logged. If two or more identical fixtures are set up with
the same DMX address and in the same DMX mode, they will receive the same instructions
and behave identically. Setting up identical fixtures with the same address is a good tool for
troubleshooting unexpected behavior and an easy way to achieve synchronized action. Setting
DMX addresses via RDM involves running a scan to identify the fixtures that are present on the
data link and then allocating addresses either automatically or manually.
To use RDM:
1. Obtain an RDM-compatible controller such as the RDM UPGRADE INTERFACE B
(cod. AC10011A001 ) application running on a Windows PC.
2. Use a USB cable to connect the PC to a USB/DMX interface box
3. Connect the interface box to the data link.
4. Power the fixture on and carry out an RDM discovery / scan in your RDM-compatible
controller.
5. You can then configure or retrieve data from the fixtures on the data link.
