1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
Advanced DMX Multiplexer PX235 is powered with safe voltage 12 - 24V; however, during
its installation and use the following rules must be strictly observed:
1. The device may only be connected to 12 - 24V DC current (stabilized voltage) with
current-carrying capacity compatible with technical data.
2. All the conductors should be protected against mechanical and thermal damage.
3. In the event of any conductor damaging, it should be replaced with the one of the same
technical data and attestations.
4. Connection of DMX signal should be made with shielded conductor.
5. All repairs and connections of outputs or DMX signal can only be made with power off.
6. PX235 should be strictly protected against contact with water and other liquids.
7. All sudden shocks - particularly dropping - should be avoided.
8. The device cannot be turned on in places with humidity exceeding 90%.
9. The device cannot be used in places with temperature lower than +2°C or higher than
+40°C.
10. For cleaning use only a damp cloth.
Advanced DMX Multiplexer is a complex device that allows to change analog signal 0-
10V to the DMX-512 signal. Analog signal is converted into a digital signal and then it is
inserted or replaced at the appropriate (chosen by the user) DMX channel from the DMX-
512 package.
It has eight inputs parametrized as a 0-10V analog or digital (active with low or high
state). In case of choosing replacing of DMX channels by the converted analog signal, the
last channel DMX-512 package are cut to make room for the added channels (their number
depends on the number of analog inputs are connected).
The PX235 has built-in one input and output of DMX signal. Color display provides a
graphical representation of information about the state of the signal and thus its' control.
Pulse input allows to cooperate with the PNP and NPN signals (e.g. wind sensors
connected - anemometer). Signal parameters and the current value are displayed on the
display screen. The USB connector allows communication with a computer and simplifies
update firmware installed on the PX235.
Built-in OC output (Open Collector) allows you to configure and then signaling the set
of states in the form of alarms. The device also has a 10V output that can power analog
sensors such as potentiometers and photometers.
Starting from Px235 serial number: 13091243. a new firmware 2.0 has been
introduced. It may only be used with PC software version 2.0 or higher.

The presentation of the DMX signal:
The value of DMX signal to the frame (DMX channel) is portrayed as a white
column, whose height varies proportionally according to the formula: the highest =
largest value of DMX signal - 255, no column = no DMX signal, value is 0.
Number of frame (DMX channel) is described on the left, respectively: 1, 129,
257, 385 for subsequent lines. In addition, each line is divided into parts, where red dots
means another ten channels, and green ones the next 100 channels.
After selecting a submenu on the screen show up currently
set parameters of the DMX signal. Default values set on the device are visible below.

Packet length Refresh rate

1.Break Time allows to change the length of the interval between successive DMX
packets. Break signal may take longer, but can not be less than 120 microseconds.
Usually it lasts about 120-140 microseconds.
2. MAB Time (Mark after break) is the interval time that occurs in each package
according to the standard DMX-512. The PX235 allows minimum value of 16
microseconds.
3. MBF (Mark Between Frame) -
frame (end of the 2nd stop bit) and the start of the next - Mark Time Between Frames
(MTBF) is the full name. Its length can range from 0 to 1000 microseconds, the shorter
the better.
4. Packet gap - the amount of time between packets. Its length can range from 16 to
5000 microseconds.
5. Channels number - Using this feature, you can limit the number of channels sent
from the PX235. The minimum value is 24 channels and the maximum is 512 (default).

7.4. WIND SPEED > DMX
7.5. DMX PATCHING
Wind speed onto the DMX is a function that allows you to set parameters of conversion
of the voltage signal from the anemometers to values compatible with DMX protocol. To
set the limit values You need to approve with the enter the set button on the screen and
follow the point 4 on page 2. Changes made to the settings are shown graphically in the
chart.
DMX Patching allows to assign the subsequent channels of DMX512 package output
value from both DMX inputs, as well as analog and counter input. It is also possible to
set each channel to a constant value of 0 or 255 (default channels 511 and 512 are set to
0 and 255).
A parameter in the default
settings is 0. B parameter
value is 50.

7.6. COUNTER INPUT SETTINGS
7.7. ALERT OUTPUT
Counting Input Settings menu allows to change some values and the characteristic
parameter of the anemometer (Transducer output) of formula 1 [Hz] = x [m / s].
The default is set to 0.1 [m / s], but be sure to check this parameter and (if needed) to
change after connection of the new anemometer.
Another option you can set is the counting input configuration. Sometimes there is need
to change the type of electric signal amplifying transistor (PNP or NPN) dependent on
the anemometers (or if both types of method connecting to the device are used).
To change the type select the field and confirm with .polarization enter
Alarm output allows the individual set the parameters on and off the alarm output. Time
On Set determines how many seconds takes to turn on the alarm, during which the wind
speed exceeds a threshold alarm. Time Off Set is the time after which the alarm turns
off, the alarm status changes if wind speed decreases below the predetermined
threshold.
