ILDA Streaming - easily transmit ILDA over LAN

ILDA Streaming describes the transmission of the analog ILDA laser control signal over a digital network.
The ShowNET is capable of ILDA streaming: It requires a sender, which takes up the ILDA signal of another device, e.g. a USB interface, and transforms it to a digital signal in real time. Sender always needs to be an external ShowNET interface, as those have an ILDA inputn interface.
The receiver in an ILDA streaming environment can be any Laser with ShowNET mainboard or any external ShowNET device.

The transfer of the data via network works with a standard network protocol. Thus it is possible to use switches to split up the signal, transmit it via fibre or V-LAN or other common methods. This helps to get rid of long and bulky ILDA cables, but also allows for much longer signal transfer distances. So instead of having to run multiple ILDA lines from teh FoH to the stage, it is only one network cable - even for multiple laser systems!

1. Understand the wiring scheme:

2. The ILDA signal, that comes from any ILDA DAC (USB DAC, Lasergraph DSP, FB3, etc.) is connected with a short ilda cable to the ILDA IN of an external ShowNET device.

3. Use standard LAN-cable (Ethernet-cable), minimum of standard CAT-5 (most cables are), and connect the ShowNET interface to the target Laser with integrated ShowNET Laser mainboard or another external ShowNET. The LAN cable can be very long, the signal can be distributed with standard network switches, can be transmitted over fibre or V-LAN, etc. ... just like a normal network signal.

Configure Sender and Receiver Device

The Sender ShowNET device has to be an external ShowNET interface. Teh external ShowNET interface has an ILDA input port, where the ILDA laser control signal of another Laser DAC, e.g. a Pangolin FB3 or a Lasergraph DSP, can be feeded in. This can be done with a short ILDA cable.
The Sender ShowNET then needs to be assigned a specific IP address, so it can directly communicate with teh related receiver device later. It is always a pre-defined pair of sender and receiver that communicate with each other.<br
This is the address chart that shows the correlation between sender and receiver. It also shows how the address setting has to be done:

Like in any IP based network, each device in the network MUST have an individual IP address! It is NOT possible that any device has the same IP address, this will lead to conflicts!
So Sender and Reciever are always a pair - it is not possible to have one Sender sending it's signal to two Receivers. To achieve that, use a Y-Splitter on teh ILDA signal before feeding it to the Senders and use two Sender-Receiver-pairs.

The sender uses an IP address range between and and trans-mits the signal to a receiver that has addresses in the range between and The specific IP addresses need to be set with DIP switches. Make sure there are no other devices in the same network that use the same IP addresses.

ILDA Streaming - Chart

Example: Sender IP address setting:

ILDA Streaming - sender

This assigns IP address to the Sender. The corresponding receiver needs this IP address setting:

ILDA Streaming - receiver

This assigns IP address to the receiver. The only difference between sender and receiver configuration is dip switch 5, which is 0 for the sender and 1 for the receiver.
