1. GENERAL DESCRIPTION
PX359 is a device to convert the DMX steering signal into the appropriate commands sent with
the use of RS-232.
The device is equipped with two independent buses RS-232, which various commands can be
sent to.
PX359 is programmed with the use of the web interface through the Internet browser without the
need to install additional software and controllers.
The device also supports the RDM protocol with which some parameters, for instance,
an IP address can be set.
2. SAFETY CONDITIONS
Controller PX359 RS232 - DMX Interface 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 can be connected to 12-24 V DC (stabilised voltage) with current-carrying capacity
compatible with technical data.
2. All the conductors should be protected against mechanical and thermal damage.
3. In case of damage to a conductor, it should be replaced with a conductor of the same technical
parameters.
4. Connection of DMX signal can be made with a shielded conductor only.
5. All repairs, connecting and disconnecting of cables can only be made with cut off power supply.
6. The device 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. Clean with damp cloth only.

4. OPERATION OF THE DEVICE
On the housing of the device there are four diodes signalling the condition of the device.

POWER
It is permanently on when the device is on
DMX
It blinks when the device receives a DMX signal
COM 1
It blinks every time when it sends a command
on the first RS-232 line
COM 2
It blinks every time when it sends a command
on the second RS-232 line
4.2. Reset button
On the housing of the device there is a button “reset.” Pressing it for a short time restarts the
device.
Pressing this button for a longer time (over 10 seconds) restores default settings. It will be
signalled by lighting all the diodes one after another.
4.3. Dipswitch of the address
The PX359 device has a physical dipswitch button which can be used to set its base DMX
address. If the value 0 is set on the physical switch, the device accepts the DMX address saved in
memory. Then, it can be edited by a webserver or the RDM protocol.

5. CONFIGURATION OF THE DEVICE
The PX359 device enables to configure network settings, a DMX address, settings of the RS-232
signal and make a list of commands sent from the device.
All the parameters can be configured by the web interface. Some parameters can also be set with
the use of the RDM protocol.
5.1. User’s interface
To be able to configure the device with the use of the web interface, the up-to-date IP address of
the device should be entered in the Internet browser. The computer and the device have to be in
one subnet.
The default IP address of the device is:
192.168.0.50
PX359 does not support the DHCP protocol.
If there are several PX359 converters pinned to one network, their IP addresses should be
changed individually to avoid a conflict.
EXAMPLE:
The network settings of the computer while connecting with the device with a default IP address:
IP: 192.168.0.50
Mask: 255.255.255.0
The user’s interface divided into bookmarks will be displayed in the browser after the correct
connection.
5.2. Summary
In the bookmark [Summary] there is the most essential information concerning the device:
ŸDescription
ŸSerial number
ŸVersion of firmware software
ŸBootloader version
ŸWorking time since the last restart
ŸLabel which can be changed

7
5.3. Network settings
The user can change the following in this bookmark:
ŸIP address
ŸMask
ŸGate
The changes will be applied after restarting the device. To restart the device, you should go
to the bookmark [Administration].
Here, the MAC address of the device and the detected bandwidth are also visible.
5.4. DMX settings
The PX359 device has a physical dipswitch button which can be used to set its base DMX
address. If the value 0 is set on the physical switch, the device accepts the DMX address saved in
memory.
[Current DMX Address] of the device is displayed in the bookmark [DMX settings]. Below
viewing of the [DMX Hardware switch] and the window to change the DMX programme address
are visible.
EXAMPLE 1:
DMX Hardware switch: 0
Base address: 25
Current DMX Address: 25
EXAMPLE 2:
DMX Hardware switch: 7 *)
Base address: 25
Current DMX Address: 7
Additionally, the required [Minimal time duration] a value can be set on the DMX channel to
translate it into the RS-232 command.
*) -
5.5. DMX monitoring
Viewing of the received DMX signal is visible in this bookmark.

5.6. RS232 settings
The bookmark enables to set the parameters for both RS-232 buses independently:
ŸBaudrate [bps]
-1200
-2400
-4800
-9600
-14400
-19200
ŸData bits
-8
-9
ŸStop bits
-1
-2
The parameters have to be in accordance with the settings on the receiving device.
-28800
-38400
-57600
-115200
-230400
ŸParity
-brak
-even
-odd
5.7. Commands
In the bookmark [Commands] there is a list of all commands defined by a user.
The following can be defined for each command:
ŸName – a character string enabling a user to identify a given command easily
ŸContent – a character string which will be sent as a command via the RS bus. The value can
be given in the form of ASCII characters or hexadecimally. To enter the value in the ASCII
editor which does not have its representation, it should be given hexadecimally in the curly
brackets. Below, supervisorily, the length of commands in bytes is given. The commands
have to be in accordance with the requirements of the receiving device. You should draw your
attention to the signs such as the sign of the end of the line.
ŸDMX offset – the relative number of the DMX channel where the value has to appear so that
the command could be sent. Offset is added to the base address of the device.
EXAMPLE:
a base address: 5
offset: 3
the command will be sent in reaction to the value on the 8 DMX channel.

9
ŸMinimum and maximum – the range in which the value should be in the channel so that
a command will be sent.
ŸRepeat … what – if the option is a marked, a command will be sent periodically every given
number of milliseconds, as long as a value in the chosen channel is within the range. If the
option is not marked, the command will be sent only once while entering the range. In such
a case, to send a command once again, you should change a value in the steering channel so
that it will go beyond the range, and then reset it in the range.
ŸSend to… – the option allows to choose which bus the given command should be sent to.
5.8. Administration
In the bookmark [Administration] there are the following options:
ŸExport all settings – it will export all settings of the device to a file
ŸExport commands list – it will export only a list of commands to a file
ŸImport from file – it will import all settings from a file or only a list of commands (depending on
the chosen file). This option will overwrite current settings.
ŸLanguage – a change of interface language. English or Polish can be chosen.
ŸFirmware upgrade – it updates software of the device. The latest software can always be
found on the producer’s website www.pxm.pl
ŸReboot device
-Save changes – it saves all
-Discard changes – it restarts the device without saving changes
-Reset to factory defaults – it restores the default settings of the device
NOTICE: the whole current configuration of the device will be overwritten.

5.10. RDM
The PX359 supports the DMX-RDM protocol. DMX protocol allows only of a one-way data
transmission, while its extension the RDM protocol can transmit information in two directions.
This makes possible to simultaneously send and receive information, and hence the possibility of
monitoring activities of the compatible devices. Thanks to RDM some available settings of
compatible devices may be programmed using this protocol.
Below is a list of RDM parameters supported by the PX359:
