Renard 24HC

The Renard 24HC Dimmer is the lastest edition of Frank Kostyun's 24 Channel All-In-One Christmas Lights Controller.

WLC Ventures now stocks the Renard 24HC here.

Schematic

Previous comments about the schematic being identical to the Renard 64 is not correct.

RavingLunatic created the schematic below by tracing out the board. Note that this is NOT an official schematic, may have errors, and some reference designators are were derived for this schematic. This schematic is old and is being revised.

Renard 24 Assembly Instructions - original

Testing Points

The HC has 7 test points (TP1 to TP7)

TP1: GND
TP2: +5VDC
TP3: +12v
TP4: 12vac
TP5: 12vac
TP6: RS485A / RJ45 Pin 5
TP7: RS485B / RJ45 Pin 4

Design Notes for the HC PCB

The COMM FR LED pads are backwards - the cathode (short leg on the LED) will go into the round hole

Renard 24HC Jumper Settings and Options

120/240v Jumpers: Allow for setting the transformers input voltage (labeled as JP1 and JP2.)

Zero Cross: If on, the board will insert the zero cross signal on the RJ45 pin 3 (labeled as JP3.) This is used to send a ZC signal to another board such as a Ren64 or Ren16.


Transformer On/Off: If on, the transformer recieves power from the left power input.


12v Jumpers: Located below the transformer, these can be installed to use the board in 12vac only mode (for use with MR16 LED lamps, also labeled as JP5 and JP6.)

PC to Renard Cable

The Renard 24 board has on-board power supply circuitry and on-board zero-crossing circuitry, so all that it needs on the RJ45 cable are data signals and ground. If you are using RS232 input and connecting it directly to the PC serial port, the following cable pin outs will work:


PC DB9 Pin 3 to RJ45-pin 4
PC DB9 Pin 5 to RJ45-pins 1,2,5 (pins 1 and 5 are required, pin 2 is optional).

If you are using a RS-232 to RS-485 converter, the pinout is Pin 5 to A+ and Pin 4 to B-. This is the same as for the Ren 16.

Female DB9 connector as if you were looking into the end of it from the outside. sink.

Errata for Rev HC PCB
