Demultiplexer DMX512 signal - DMX / 0-10 V Interface 8ch
The PX227 is designed to process the DMX512 signal to control the eight analog 0 - 10 V outputs
(with accuracy +/- 3%). The device is manufactured in a housing designed for installation in
electrical switchgear DIN rail T35.
In addition to simple decoding DMX signal the PX227 allows you to select the characteristics of
control and to program unit reacts to loss of DMX signal.
Individually programmable parameters allow to define independent for each channel DMX
address from range 1-512. What is more you can arbitrarily assign multiple channels to a single
address.
1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
PX227 is a device powered by low voltage equal to 12-24V; however, please observe the
following safety rules during its installation and use:
1. Installation of the device, and in particular, connection of power, should be conducted by a
suitably qualified person, as described in the manual.
2. The device can be connected only to the power supply of 12-24V DC (stabilized voltage) with a
load capacity compatible with technical data.
3. Protect all cables against mechanical and thermal damage.
4. In case of failure of any of the cables, it must be replaced with a cable of the same technical
parameters.
5. Only a shielded cable must be used to connect the DMX signal.
6. The device may only be installed in closed housing.
7. All repairs and connections of outputs or DMX signal can only be carried out with power
disconnected.
8. PX227 must be strictly protected against contact with water or other liquids.
9. Avoid sudden shocks, particularly dropping.
10. Do not operate the device in rooms with humidity above 90%.
11. The device must not be used in rooms with a temperature below 2 °C or above 40 °C.

Examples of connection:
5. DMX SIGNAL CONNECTION
PX227 must be connected to DMX line in series. This means
that DMX IN terminals in the device must be provided with the
driving cable, and then from DMX OUT connector the driving
cable must be provided to other DMX receivers.
If PX227 is the last device in DMX line, "DMX+" and "DMX-”
terminals must be provided with the terminator – resistor of 120
Ohm between pins 22 and 23.

After switching on, the display shows the version of the program. During the normal operation of
demultiplexer, the display shows only one dot. Press “enter” to go to the main menu, the display
shows ALL. Press "previous" or "next" to select the programming menu ( ALL, Ind, dEF) and
press "enter" to confirm.
7. PROGRAMMING OF GROUP PARAMETERS
Programming in this menu is common to all channels.
After selecting ALL from the main menu, confirm selection by pressing "enter", then with "next" or
"previous" select the parameters to be set:
Adr - DMX address of the device,
Cur - feature of channel dimming,
noS - response of the device to the loss of DMX signal,
Sth - the function of smoothing the transitions between different values.
The next step is to confirm selection by pressing "enter".
The address or feature programmed in this way will delete the previous individual settings of the
channels.

7.2. Feature of output channels
7.1 Setting of DMX address
PX227 menu allows you to set DMX address of the device in the range from 1 to 505.
In order to set DMX address:
1. Set the Adr function.
2. By using "next" or "previous" set the selected DMX address. In order to accept the settings,
press "enter".

of group settings ALL
2. Press "enter" again in order to change the settings for all channels
3. Use „next” to select Cur. This will allow you to change the characteristic of channel dimming.

7.3. Response to the loss of DMX signal
This function is used both to protect the system against the disappearance of DMX signal and to
gain a specific state on outputs. After it has been activated, in case of a lack of DMX signal, the
module will perform the selected function by itself. The reconnecting of DMX signal will
automatically break the performed function, and the module will again be controlled by DMX
signal.

Detailed information on the configuration of the individual programs and scenes
can be found in section 9 of the manual (Defining / setting scenes and programs).
The HLd function keeps the last DMX value on the output when the signal is lost.
The device also has the smoothing option. Smoothing allows for smooth color changes. When
this option is enabled, switching between successive DMX values sent to channels is smooth,
which prevents abrupt changes in voltage.

The enabled smoothing function can slightly slow down the device response to the change of
DMX signal, so it is possible to switch off this option. In order to switch off smoothing, select diS
parameter and confirm the selection with "enter".
Time smoothing - time allows you to set the time of linear transitions between successive
DMX values. The minimum value is 10 [ms] and the maximum is 999 [ms]. This can be smoothly
changed by selecting the expected value using "previous" and "next" buttons.
The selection of P2P function allows linear transition between successive DMX values.
PX227 device has the option of individual settings. It allows you to assign each of the eight output
channel with any DMX address. It is possible after selecting Adr. DMX address can be selected
within a range from 1 to 512.
