v1
==
simple RDM splitter.
v0 + RDM capabitlity added.
detects and forwards RDM traffic from RJ45 to XLR.
issues:
- DMX_OUT should be on PB10/PB11, not PB11/PB12
- RDM LED is on, because the signal line is not driven
v0
==
simple DMX splitter.
forwards DMX512 data from XLR to RJ45 (ANSI E1.11-2008 §7).
adds 6-60V 2A passive PoE (802.310/100 mode B).
never tested.

@ -22,10 +22,6 @@ Using RDM, you can:
Now devices can be configured remotely, and no ladder is require anymore.
The RDM splitter is actually a DMX splitter with RDM support.
If you don't need RDM, just don't place the MCU (and passives next to it).
The board will still work as DMX splitter.
The WLED chain hardware is RDM capable.
Software support needs to be added.
For now you still have to use the web interface to configure it.
@ -52,7 +48,7 @@ The RDM splitter board needs to be powered to operate.
The DMX512 data will then be copied from the XLR chain to the RJ45 port for WLED chain.
The power can come from the 2.1/5.5 barrel jack (marked VIN), the spring terminals (the two terminals next to VIN), or from the WLED chain through the RJ45 port or corresponding terminal.
There is an over-current protection on VIN using a 2.2 A PPTC polymer fuse.
There is an over-current protection on VIN using a 2.2 A PPTC resettable fuse.
PoE++ allows only up to 960 mA per pair.
We are using two pairs for power transfer, thus allowing a little under 2 A.
This limitation is because CAT5 cables use AWG 24 wires, with a resistance of 0.2 Ohm/m.
@ -64,11 +60,14 @@ It uses a inline diode.
Thus, on the WLED chain device the voltage will be at least 0.5V lower.
Take this into account when reusing this power rails from the WLED chain.
If you do not require RDM support, you can skip populating the MCU and related components on the top right corner.
By default the RDM splitter will still act as DMX splitter.
The yellow LED on the RJ45 port lights on when power is available on VIN.
The green LED on the RJ45 port light on when the electronic on the board is powered, using the on-board DC to DC buck regulator to 5V.
The blue DMX LED on the center of the board blinks upon DMX512 traffic from the XLR port to RJ45.
The red RDM LED on the center of the board blinks upon RDM traffic from the RJ45 port to XLR.
The blue DMX LED on the center of the board is off by default, and blinks upon DMX512 traffic from the XLR port to RJ45.
The red RDM LED on the center of the board is on by default, and blinks upon RDM traffic from the RJ45 port to XLR.
The green RUN LED in the corner of the board turns on when RDM support is active.
The board can be mounted in waterproof enclosures (for [sonoff](https://www.sonoffegypt.com/products/sonoff-ip66-waterproof-case) or generic [100x68x50 mm](https://www.aliexpress.com/item/1005005622148025.html)).
