RE-DM4 and RE-DM6 RADIA Eclipse Dimmer Modules
SEND_COMMANDs
The Radia Eclipse firmware supports the SEND_COMMANDs listed in the table below. The number of
SEND_COMMANDs is expected to grow as we transition away from using the SEND_STRING method
of controlling Radia dimmers.
Note that most SEND_COMMANDs do not have responses. With those that do, they respond with a
COMMAND, not a string.
Conventions used in this protocol section of the document include:
Ramp preset up (NEW)
This function ramps up the specified or currently active (last recalled) preset until the ramp is stopped or
the all dimmers in the preset reach 100%. If <preset> is not specified, then the last recalled preset is
ramped.
The ramp rate for this function is the default ramp time as established by the 'RT' command. Only
dimmers that are assigned a level greater than 0 in the preset are ramped. Dimmers with a level of 0 and
Undefined dimmers are not affected by the PU command.
SEND_COMMAND Protocol Conventions
Symbol Function Values
<m> Value for Dimmer Level (in %) 0-100
<n> Value for Dimmer Number 1-6 or A for all. Can include a range of dimmers or
ranges of dimmers unless noted otherwise. For
example:
“1-3” indicates dimmers 1 through 3 inclusive.
“1-3&5-6” indicates dimmers 1 through 3 and 5
through 6, inclusive.
“A” indicates ALL dimmers.
<s> Value for preset number 1-128
<t> Time value for fade (in sec-
onds)
0-255
Use the 'PS' command to stop preset ramping. This command allows the
programmer to specify which preset to stop.
