System Setup; Setting Options By Rdm; Scanning For Rdm Devices On The Data Link; Getting Status And Setting Options By Rdm - Martin VDO Atomic Dot User Manual

System Setup

All setup options for the VDO Atomic Dot are configured over the data link.
If you are using a Martin P3 system to control the fixture, please refer to the P3 System Controller
user manual and instruction videos.
For DMX, Art-Net and sACN the fixture is configured using RDM.
It is also possible to configure the VDO Atomic Dot fixtures using a P3 System Controller (or P3-
PC) to set DMX start addresses, DMX modes, DMX universes and other parameters. Once the
fixtures are configured you can then run the fixtures directly using DMX, Art-Net or sACN without
using the P3 System Controller.

Setting options by RDM

The VDO Atomic Dot fixture is remotely configured over the DMX line using RDM.
A full list of the RDM functions that the VDO Atomic Dot fixture supports is given at the end of this
chapter. These functions are generally referred to using the more specific term 'PIDs' or
'Parameter IDs'.

Scanning for RDM devices on the data link

Before you can communicate with fixtures using RDM, you must send a scan command (also
called a device discovery command) to all the devices on the data link so that the RDM controller
can identify them. It does this by retrieving each device's factory-set unique identifier (UID). This
process can take some time depending on the number of devices on the link.
To identify the fixtures on the link:
1. Check that the fixtures are correctly connected to the RDM controller on the data link and that
power is applied to all fixtures.
2. Give the controller time to identify the devices on the link and prepare for communication with
the devices.

Getting status and setting options by RDM

The status and options listed in the table below can be read and set by RDM.
You can set an option on one fixture by sending a unicast RDM command to that one fixture only,
or you can set the same option on all the fixtures on the data link by sending a broadcast RDM
command to all the devices on the link.
For status reading, you can only use unicast RDM to read information from an individual fixture.
