Page 3: Description
Description PX257 is a device made in two versions: 8 Relay Module and Switch 8x1.3A OC. It is used for switching on and off stage lighting and theatrical effects as well as architectural lighting equipment using the DMX-512 signal. The module incorporates a set of 8 relays that control on / off outputs. The PX257 OC version is an 8-channel digital DC switch, featuring maximum single circuit switching load of 1.3A. -
Page 4: Safety Condition
Safety condition The PX257 is a device powered with safe voltage 12 – 24V DC; 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. -

- Page 12 output that is switched on is the one whose DMX channel was first to be enabled. The same as in on1 mode its possible to change the time between disable one of output in pair and enable the second output in pair. By way of example: The action of switching on the first DMX channel will cause the first output to be switched on.

Page 14: Hysteresis Thresholds
4.6 Hysteresis thresholds The device can employ hysteresis which prevents relay contact vibration during switching on and off. Two hysteresis thresholds are applied, one for switching to the on position, the other – to the oFF position. If the lower hysteresis threshold is below the upper one, a normal characteristic is obtained. -

One of the messages that will be displayed will say dFl, which means successful restoring to default settings (the “prev” key has to be held down while powering on the device, until the dFl message is displayed).
- Page 17 Please note that after restoring to default settings, all the operating parameters of the device will revert to the following ones: DMX address: 1 • complementary outputs: off • no signal operating mode: off • • hysteresis thresholds: ON = 141, OFF = 115 The device incorporates an embedded memory controller.

Page 18: Dmx Signal Connection
DMX signal connection 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. -
