RDM Settings
Most RDM settings are not configurable in FluxTool and must be programmed into the driver in the factory. POWERdrive
LED drivers ship with these default RDM settings:
-
UID
–
This is a 12-digit hexadecimal number that is unique to each POWERdrive LED driver. Like a MAC address or
IP address, the UID ensures that messages can be sent to a specific POWERdrive LED driver. The UID itself is a
concatenation of these numbers:
o
Manufacturer ID
–
a 4-digit hexadecimal number that is unique to a manufacturer. The default
manufacturer ID in a POWERdrive LED driver is 0x646F (
“
eldoLED B.V.
”
)
o
OEM ID
–
an eldoLED-assigned 2-digit hexadecimal sub-number. The default value is 0x00
o
Range value
- a 6-digit hexadecimal number that is uniquely assigned by eldoLED to each individual
POWERdrive LED driver
-
Device Model Description
–
17 alphanumeric characters (A-Z+a-z+0-9, case-sensitive); default value is
“
LED
driver
”
-
Device Model ID
–
a 4-digit hexadecimal number that is hard-coded to 0x0101 for POWERdrive LED drivers
Please contact your eldoLED Sales representative if custom RDM settings for a POWERdrive LED driver is required.
7. Best Practices
To reduce the likelihood of issues in the field, it is best to communicate clearly how a DMX luminaire is configured to the
specifier, control system designer, installer, and commissioning party. The following information is, preferably, included in
the luminaire specification sheet and/or installation sheet:
-
Default DMX address. Fixtures are typically not shipped pre-addressed; fixture addressing is done by the installer
or a commissioning contractor via RDM
-
DMX channel count (footprint) of the fixture
(a)
(b)
(c)
Figure 11: In this example, LED outputs 2 and 4 are disabled via the group scaling command (a). Even though the driver
has only 2 active LED outputs, it may still be desirable to maintain the logical DMX address sequence for LED outputs 1
and 3. This is accomplished in the Network settings (b) by exposing only 3 addresses (Network channel count = 3) and
mapping LED output 1 and 3 to DMX address 1 (= Network start address) and 3 (= Network start address + 2),
respectively. If it is important, though, to conserve the number of DMX addresses that is consumed by the
POWERdrive LED driver, the Network channel count (c) can be set to 2. LED outputs 1 and 3 are then mapped
in
the
Network settings to DMX address 1 (= Network Start Address) and 2 (= Network Start A 1), respectively.
