INTRODUCTION

SPI protocols are sensitive to data distortion and often only work reliably for up to 2 meters (6.5 ft) of cable distance between the controller and first SPI IC/LED. The DiGidot PxLNet Transceiver is a small sized module that can be used as receiver or transmitter to extend the range of an SPI signal.
The PxLNet Transceiver converts PxLNet, which is send from a DiGidot PxLNet Transmitter or a
Transceiver in transmit mode, based on the original SPI protocol that is sent from a SPI controller. A
DiGidot PxLNet Transmitter or Transceiver converts sensitive SPI protocols to PxLNet which can cover huge distances, up to 250 meters (820 ft). Any SPI protocol can be received or be transmitted with this module.
Connect the same amount of universes as to the connected SPI controller can send per port.
Installation is easy thanks to the well laid out screw terminals and RJ45 connector. The output side can be easily connected with the help of a simple flathead screwdriver. No need to solder here. When this module is connected to the end of an LED strip or pixel controlled product, it can be used as a transmitter when the jumper is removed.
A PxLNet Transceiver in Transmit mode can also be connected to a DiGidot Controller output port to convert the SPI signal to PxLNet.
The PxLNet Transceiver can also be used to convert a DMX signal to DMX TTL or vice versa.

The ground connection between a DiGidot PxLNet Transmitter and a PxLNet Transceiver or multiple
Transceivers are automatically established when using the RJ45 bus with a network cable in between.

OPERATING MODES (Rx/Tx)

Receiver mode (Rx)

The default operating mode of the PxLNet Transceiver is Receiver mode (Rx).
Please make sure that the Rx/Tx jumper [5] is installed.
The PxLNet data is received, converted to the original protocol and sent on the output it’s data pin.

Transmit mode (Tx)

In order to use the PxLNet Transceiver as a single channel transmitter, connect the D (center pin of screw terminal [2] or [9] as indicated on page 5) to the incoming SPI Data signal. Remove the Tx/Rx jumper [5] as indicated, to activate transmit (Tx) mode.

Connect a network cable to the RJ45 bus and connect it to the next PxLNet Transceiver in receiving mode (Rx).
Instead of connecting a network cable to the RJ45 bus, a cable can also be soldered to solder pads [11][12][13] on the bottom side (as indicated on page 5).

The distance between two PxLNet Transmitters is max. 250 meters (820 ft).

Wiring schemes

Following wiring schemes show various options to connect this product. There are many more connection options and combinations possible which may not be listed in this manual.
As long as following wiring principals are followed, a wide range installation options can be created.

• PxLNet Transceivers must be powered properly as indicated.
• If LED products need to be powered at other voltages than 5-48 Vdc, separate powering is required. In this case all grounds must be connected at any time.
• Use proper network cables or DMX cables as indicated on page 8. Thicker wires and higher cable impedance may result in unstable or corrupted data.

Wiring scheme 1 option 1 Convert PxLNet to SPI Data

DiGidot Controller with PxLNet Transmitter connected by Cat-5E network cables to PxLNet
Transceivers. The wires from the LED strips are screwed in on the other side to the Screw Terminals.

Wiring scheme 1 option 2 Supply power at a different location

Same as #1 but the power supply is connected further on the LED strip and then the power travels through the LED strip to feed the Transceiver.

DiGidot Controller with PxLNet Transmitter connected by Cat-5E network cables which are connected to PxLNet Transceivers, which are wired to pixel controlled LED products, that run on another power supply and/or voltage.

Wiring scheme 3 Transceiver in transmit mode

DiGidot Controller with a 3-core wire (max 2 m), to the PxLNet Transceiver in Transmit mode and has no jumper installed. The PxLNet Transceiver on the other end (left of the image) is in Receiver mode and they’re connected with a CAT- 5E network cable. This same setup of Transceivers can be used between the Controller and the LED tape, but also between 2 LED tapes so the tapes themselves can be further away from each other as shown in the next wiring scheme.

Wiring scheme 4 Daisy-chain Transceivers

DiGidot Controller with a PxLNet Transmitter connected with a CAT-5 E cable directly to a PxLNet
Transceiver. Then the LED strip is connected to the Screw Terminals. At the end of the LED strip, the
Transceiver is used in Transmit mode (no jumper present) to convert the data signal to a PxLNet signal up to 250 meters away to the next PxLNet Transceiver.

Wiring scheme 5 Convert PxLNet to SPI Data + Clock

PxLNet Transceivers can also be used to convert two PxLNet data lines to Data

• Clock SPI signals.
  For this option a dual Transceiver setup is required.
  

Wiring scheme 6 Combine short & long range Data + Clock SPI

DiGidot Controller with a PxLNet Transmitter connected by Cat-5E network cables to PxLNet
Transceivers. The LED strip is connected to the Screw Terminals. The power is separated here into 2 area’s so they can run at different voltages.

Wiring scheme 7 Extending DMX TTL signals

DiGidot Controllers with a PxLNet Transmitter, connected by Cat-5E network cables to PxLNet
Transceivers. Please note that DMX TTL must be configured on the DiGidot Controller on the In/out configuration page.

Wiring scheme 8 Converting DMX to DMX TTL

Using an external DMX signal, connected to a PxLNet Transceiver which is connected to a DMX TTL controlled LED product. The DMX signal can be soldered, as indicated in the drawing or can be inserted in the RJ45 bus on the top side (DMX pinout according to USITT standard, see page 5)

Note: These wiring schemes do not necessarily show correct powering your LED products. All wiring schemes in this manual are for reference only, please refer to the technical information or user manual of your LED product, supplied by the manufacturer.

PROPAGATION DELAY

The PxLNet Transceiver is designed to relay signals at very high speeds.
When multiple PxLNet Transceivers are used to extend the signal, there is a negligible build up of propagation delay of only 1,6 µs (micro seconds), which is equal to ± 2 SPI IC’s.
This means that large numbers of PxLNet Transceivers (possibly more than 100), can be used without visual decline of performance. It’s safe to assume that in case any visual performance decrease, it’s most likely due to other (external) factors.

AUXILIARY BREAK OUT

The PxLNet Transceiver uses at least 3 wires: Data +, Data – and GND (GND is connected twice) for the PxLNet signal, this means that there are two (blue and green) unused wire pairs inside a network cable (not applicable to DMX cable). These wires can be used for low voltage purpose up to 48 Vdc and a maximum current of 200 mA. Use solder pads [14][15][16][17] to make use of these wires.
