1 Description
DMX signal splitter enables branching in complex DMX installations.
The combination of a large number of receivers in series can be troublesome,
therefore it was possible to create branching DMX tracks using a splitter.
The PX349 supports the RDM protocol, which allows bidirectional packet
transmission.
With PX349, it possible to split the DMX input signal into four independent
branches. The individual outputs are galvanically isolated from input
and between each other. The output signals are appropriately reinforces,
which guarantees correct operation of the entire installation.
Splitter DMX-RDM is manufactured in a housing adapted for mounting
on standard DIN 35mm rails.

2 Safety conditions
Splitter PX349 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 be connected to 12 – 24V DC (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 damaging any conductor, it should be replaced with
a conductor of the same technical data.
4. Only use a shielded cable for connecting the DMX signal.
5. All repairs and connection of outputs or DMX signal can only be made
with cut off power supply.
6. PX349 should be strictly protected against contact with water
and other liquids.
7. All sudden shocks, particularly dropping, should be avoided.
8. Do not connect the device with a damaged (broken) housing
to the power supply.
9. The device cannot be turned on in places with humidity exceeding
90%.
10. The device cannot be used in places with temperature lower than +2°C
or higher than +40°C.
11. Clean with damp cloth only – splitter should be cut off from power
supply.

4 DMX signal connection
PX349 have to be connected to DMX line in serial mode, with no branches
on DMX control cable. That mean that DMX line, from the signal source, must
be connected to DMX IN pins of PX349 and later, directly from DMX THRU pins
to the next device in DMX chain.
If the PX349 is the last DMX chain receiver (there is no connected receiver
for the DMX THRU output), it is necessary to shorten 1 0R pins – the bridge
on these pins will act as a terminator (120 Ohm resistor).

Each of the four splitter outputs is treated as the start of a new DMX line.
A maximum of 32 devices can be connected with the DMX line, with the length
up to 500 meters. In the last device of each DMX output line it is necessary
to connect the terminator.
NOTE! A maximum of 4 splitters can be connected in a cascade (the scheme
is on the next page).
