The PX257 is a device manufactured in two versions: 8 Relay Module or OC Switch

8x1.3A. The product is used to switch on and off the stage effects and architectural illumination

using DMX-512 protocol. The module contains a set of 8 relays that control on / off type outputs.

The OC version of PX257 is an 8-channel, digital electronic link with a maximum DC

load switching one circuit of 1.3A. In 8 Relay Module version the devices' menu allows you to

program the DMX address for all output channels, and set to control the characteristics of an

electric motor.

In both versions of the device is designed for mounting on standard DIN rails in electrical

switchgear.

1. GENERAL DESCRIPTION

2. SAFETY CONDITIONS

The PX257 is a device powered with safe voltage 12-24 V; however, during its

installation and use the following rules must be strictly observed:

1. The device may only be connected to the 12-24V DC power supply (stabilized voltage) with

current-carrying capacity compatible with technical data.

2. All conductors should be protected against any mechanical and thermal damage.

3. In case of any wire damaging, it should be replaced with one of the same parameters.

4. Connection of DMX signal should be made only shielded conductor.

5. All repairs or wire connection can only be made with power supply disconnected.

6. In case of connecting output relays to 230V mains You should be double cautious because of

the risk of getting electrocuted (applies to PX257-RE).

7. PX257 should be strictly protected against contact with water and other liquids.

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.

Programming in this menu is common to all channels. After selecting from the main menu

press ENTER button to confirm, then using NEXT or PREVIOUS buttons select parameters you

want to set:

- DMX address,

- response of the unit to the DMX signal loss,

- Enable or disable the complementary outputs,

- Enable or disable reversed characteristic,

and then confirm your selection by pressing ENTER.

4.4. PROGRAMMING GROUP PARAMETERS (MENU ALL)

Enabling of the output occurs when passing DMX value of 141. Disable of the output follows

passing back (from higher value) DMX value of 115.

4.3. DMX channel value for the output turning on and off.

4.4.1. DMX address

In this menu you can change DMX address assignment to available channels.

To change it you need to select in menu and confirm your choice by pressing

ENTER. Using NEXT or PREVIOUS buttons you can set the desired DMX address selecting a

value from 1 to 512 and pressing ENTER. This address will be assigned to the first channel, the

next channels will be assigned following DMX addresses. After such assignment (to address 1)

the eight channel will be addressed with no. 8. Select another parameter to set or press the

ESCAPE back to the main menu.

Programmed in such way DMX address erases previous individual settings for each channel.

4.4.2. Reaction of the device to DMX signal interruption

After you select in menu confirm your choice by pressing ENTER. Using NEXT or

PREVIOUS buttons select a desired option and press ENTER.

- programs available in the menu;

- a scene that can be programmed;

- switching on all outputs,

- switching of all outputs

To set up the program, go to the menu by pressing the ENTER button and select using

NEXT or PREV buttons desired program ( ), confirm the choice by pressing ENTER.

Principle of operation programs can be observed both on the outputs connected to PX257 and

the LEDs that are located above display.

all outputs and LEDs are switched on and blink at the same time.

outputs and LEDs are blinking alternately in the two groups, the first group is outputs

1-4, and the second group to inputs 5-8.

outputs and LEDs are blinking one after the other, Once one goes out another turns on

in the direction from the output No. 1 to output No. 8.

output and LEDs are blinking one after the other, Once one goes out another turns on in

the direction from output No. 8 to output No. 1.

this option allows us to adjust the speed of the scene from 0.1 sec to 60 sec.

To set the speed of the scene, go to the menu approving with ENTER button in the selected

program, press ENTER and press NEXT or PREV to set appropriate value for the speed, any

changes will be visible on the outputs as well as the control LEDs for each channel. You need to

approve the changes with the Enter button.

allows you to select a static scene, what means to choose outputs to be activated in the

absence of DMX signal.

To select all outputs responsible for a static scene, press the ENTER button on the

menu, then use the NEXT or PREV button to set the chosen input marked as Ou1 - Ou8 and press

ENTER. Subsequently you need to set using NEXT or PREV buttons to a value indicating

the inclusion of one of the outputs or to disable the output. Repeat the procedure to set all

outputs as expected.

CLR

This feature is used not only to protect the installation from DMX signal interruption, but also to control the outputs without the external controller. After the feature is programmed, when the DMX signal is not present, the module will realize the selected function independently. When the DMX signal is connected again, the module stops playing the function and starts working according to the commands transmitted through the DMX line.

The device is equipped with complementary output option. For PX257 "Relay" version this

function allows you to start the mode in which the outputs work in pairs, where one in the pair is

turned on, and the other is off. The complementary pairs establish outputs 1-2, 3-4, 5-6 and 7-8.

The way the function works is described below. This function is used e.g. for controlling electric

motors.

To activate this option, go to the menu and then select a value.

WARNING! If you connect an electric motor it have to be connected to the paired outputs (e.g.

output 1 - phase 1 and output 2 - phase 2). Connecting the motor phases to the unpaired output

may result short circuit.

When you activate this feature you can change

the value of delay (it is adjustable from 0.1 to 5 s)

between switching off one of the outputs in the pair,

and the activation of the second.

4.5. INDIVIDUAL PARAMETERS PROGRAMMING (MENU Ind)

In this menu, you can set the DMX address individually for 8 outputs.

After selecting from the main menu, press ENTER to confirm.

Using PREVIOUS or NEXT buttons select the output that you want to set ( - ) and

press ENTER.

Then also using PREVIOUS or NEXT buttons select a value from 1 to 512, or to turn off the

output of DMX control and press ENTER.

TERMINATOR CONNECTION

PX257 is equipped with option of reversed read the value of DMX signal. If you run this function,

the device should interpret received DMX signal value of 0 as a signal about the value of the 255.

It works similarly with the other values.

Sposób dzia³ania opcji przedstawia tabela poni¿ej:

PX257 have to be connected to DMX line in serial mode, with no branches on DMX control cable.

That means that DMX line, from the signal source, must be connected to DMX IN pins of PX257

and later, directly from DMX OUT pins to the next device in DMX chain. If the PX257 is the last

DMX chain receiver there should be terminator (resistor 120 Ohm) mounted between "DMX+"

and "DMX-" pins of DMX OUT section.
