Network Installation and Setup

DMX Downlight Installation If installing cylinder

1. Determine system layout with no more than 30 fixtures/drivers on a run (bus). 25 fixtures/drivers is recommended to allow for future flexibility. A DMX/RDM splitter is required for >30 fixtures/drivers or if star configuration is desired. DMX standard allows up to 32 “unit loads” on each bus. If additional fixtures/drivers are needed on the bus, then a repeater or signal booster is necessary. Please note that the termination resistors at each end of the run count as one “unit load”
   each. If multiple driver fixtures are utilized, each driver (unit load) must be accounted for in the system layout. See Figure 1 for an example system layout.

2. Install DMX fixtures according to included installation instructions.

3. Run DMX cable from eventual splitter or controller location to first fixture or
   DMX/RDM splitter. Daisy-chain cable from fixture to fixture.

4. Install included 3-position connectors on DMX cable as shown in Figure 2 and plug into fixtures as shown in Figure 3. Insulate bare shield wires to prevent shorting to ground.

5. Ensure the termination resistor is installed into the last luminaire in each run as shown in Figure 4. Note: Remove and discard pre-installed termination resistor from all other fixtures.

6. Use an RDM configuration* device to discover fixtures and set DMX start addresses.

7.  Install DMX controller and connect to DMX cable.

8. Configure controller according to Tables

DMX/RDM Network Notes

1. DMX Cable needs to meet the ANSI/TIA/EIA-485 standard for DMX-512 and have nominal characteristic impedance of 120 Ohms.
2.  Termination resistors are included with each luminaire and should remain installed in the last luminaire of each run to prevent erratic network behavior.
3. No more than 30 fixtures may be installed on a single run.
4. No more than 1000 ft. of wire may be installed on a single run.
5. No T-TAPS, STARS (except by a DMX/RDM splitter), splices, or Ys allowed.
6. All fixtures intended to be controlled as a zone should be given the same DMX start address. Fixtures default to a start address of 1.
7. The following RDM configuration devices are recommended for fixture addressing and configuration
   • Fresco Touchscreen
   • Fresco DXT 1M09 NE1S and DXT Sytstem Manager software
   • Goddard Design – DMXter4A RDMtm
   • Swisson – RDM Controller / DMX Tester – XMT-350

Additional Notes & Definitions

• Lighting controller: is an electronic device used in theatrical lighting design to control multiple lights at once. All lighting control consoles can control dimmers which control the intensity of the lights. A lighting controller can be a console type processor such as the Pathway CognitoTM or a wall controller such as the Acuity Controls FrescoTM.

• DMX512: is a standard for digital communication networks that are commonly used to control stage lighting and effects.
  Slot: is a sequentially numbered byte in a DMX512 packet. Slot 0 is the START Code. Slots 1 through 512 are data slots.

• Slot Footprint: is the number of data slots used by a product in its operation. Note: A 24 way dimmer rack may have a footprint of 24, it may be more if some slots are used to provide additional control functions using NULL

• START Code packets. Automated luminaires usually require a Slot Footprint of greater than one.
  Universe: is a DMX512 data link originating from a single DMX512 source. 512 data slots comprise a single universe.
  Daisy chain: is a wiring scheme in which multiple devices are wired together in series.

• RDM (Remote Device Management): is a protocol enhancement to USITT DMX512 that allows bi-directional communication between a lighting or system controller and attached RDM compliant devices over a standard DMX line. This protocol should allow configuration, status monitoring, and management of these devices in such a way that does not disturb the normal operation of standard DMX512 devices that do not recognize the RDM protocol.

• Termination resistor: is used when you are using several DMX luminaires on a single DMX line (Universe). It removes noise and flickering on the DMX line which improves the reliability of the DMX system. The termination resistor should match the cable impedance.

• Square Law Curve: is a dimming curve most closely correlating to that of traditional halogen dimming performance
  DMX Fail: This parameter defines the behavior of the device when the DMX512 control signal is lost.
  DMX Startup: This parameter defines the behavior of the device when it starts up and the DMX512 control signal is absent.

• Emergency: If the DMX signal fails, the driver (EDXB) will hold the last setting until the DMX signal is restored. In a power outage, the driver completely powers off so it will lose whatever the last DMX level was. The fixture will then be lit at the emergency backup’s max current
  setting. The emergency level is a function of the battery pack and has no correlation at all with the last DMX setting. When power is restored, if the fixture powers up before the control system and does not acknowledge any DMX signal, the driver defaults to 20% output. Once the DMX signal is restored it will operate as normal.
