1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
PX178 is a 6x7.5 A LED driver, with a built-in DMX512 signal receiver, designed to control
voltage-driven LED lamps or strips. This is the most advanced driver of its kind offered by the
PXM company. The PX 178 housing, which is 9 standard rail modules wide, features a colour
display. This allows the user to program and control the device intuitively. The built-in DMX
receiver allows for control of 6 channels (e.g. 2 x RGB) by directly using the DMX protocol. The
wide supply voltage range and high output current-carrying capacity (7.5 A) enable the user to
control large numbers of LED diodes. In addition, the driver incorporates an over-current
protection device, a temperature protection device preventing driver overheating as well as a
DMX line surge protection device.
You can control the PX178 using DMX signals or it can operate independently. In such a case, you
can choose from 8 fully programmable scenes and 8 programs, and, in relation to these scenes
and programs you can vary playback speed and step transition smoothness. Thanks to the use of
16-bit resolution, parameter adjustment in individual channels is fully variable.
The driver has a real time clock that allows you to set power ON and OFF times for the LEDs
controlled, which is particularly suitable for advertising sign light systems. Besides, the built-in
astronomical clock feature, using the current date, the co-ordinates of the driver installation
location and its position relative to universal time (Greenwich UT), automatically sets driver
output turn on and off times, on a 24-hour basis, in accordance with astronomical sunrise and
sunset times.
The driver also features an option allowing you to change the control signal adjustment frequency
("flicker free" technology), used in television broadcasting.
The USB port allows the driver to communicate with a computer. The PXM company has
developed software for setting program and scene parameters in the driver from the level of a
®
computer running the Windows system. You can download this application from PXM's website

The PX178 is a device 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 - 24 V 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
parameters.
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. The PX178 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.

To change the value of selected parameter, you must choose on the screen button "+" or "-" using
the button or , and then using the „enter” button to change the value.
After that you need to save the settings before going level up, this will allow storing value in
memory of the PX178. To do this, after moving to the screen button you need to push
„enter” button.
By skipping the [Save] stage and exit with the escape key from the menu, the changes you make
will not be saved.
Programmable buttons allow navigating the menu. Each button is described on the right side and
their use is as follows:
- allows to enter the selected option and approve set value
- scrolls up the menu or left (horizontal menu)
- scrolls back the menu or right (horizontal menu)
- exits from the currently programmed parameter without saving the changes
or goes to the upper level in the menu. Pressing the ” button while „escape
being in main menu will cause to exit to the [Summary] screen
