Dmx Address Setting - Wahlberg Roll Down Manual

DMX ADDRESS setting

The DMX address, also known as the start channel, is the first channel used to receive instructions
from the controller. For independent control, each product must be assigned to its own control
channels. The DMX address is configured in the menu as described in the section above.

Description
These channels control the position of the drum, with the speed on channel 3. The rough
position (MSB) and the fine position (LSB) is multiplied into a 16-bit channel for optimal
resolution.
However, using only the rough position (MSB) to control the position may be enough for some
applications.
This channel controls the speed and defines the max lifting and lowering speed of the drum.
This channel may also work as a brake; since the motor does not run in positioning mode unless
the channel is set above 0%.
Channel 4 is used as a safety channel with the following functions.
Values between 50% and 55% will make the product run.
All other values will make the motor stop, reset errors and eventually save the current position
before a power down.
Make sure to leave this channel at 0% before a regular power down. Doing so will save the
current position and the unit is ready to position when powered on. If it is not saved before
shutdown the soft top limit must be set again when the unit is powered on.
Channel 5 is used to manually move the fabric up and setting the soft TOP. When the value is
set ≥ 2% the drum will move up until it reaches the hard TOP limit. 2 – 100% makes the motor
run up, at variable speeds (2% = low speed – 100% = full speed).
There is a 3 second delay from channel activation to actual movement to reduce accidental
limit overwrites.
When returning this fader to 0% the drum returns to the current wanted position given by
channel 1&2, provided the unit has a valid soft bottom limit too and the speed on channel 3 is
not zero.
Channel 6 is used to manually move the fabric down and setting the soft BOTTOM. When the
value is set ≥ 2% the drum will move down until it reaches the hard BOTTOM limit. 2 – 100%
makes the motor run down, at variable speeds (2% = low speed – 100% = full speed).
There is a 3 second delay from channel activation to actual movement to reduce accidental
limit overwrites.
When returning this fader to 0% the drum returns to the current wanted position given by
channel 1&2, provided the unit has a valid soft bottom limit too and the speed on channel 3 is
not zero.
When setting the soft limits the soft top limit must always be set before the soft bottom limit.
When both soft limits have been set the internal range is calculated (TAC RANGE) is calculated.
The new range is the number of encoder pulses between the soft top limit and soft bottom
limit which corelates to 0% position and 100% position on channel 1&2.
