Renard 24 Assembly Instructions - original

Testing the v 3.3 Board

Version 3.3 has 7 test points (TP1 to TP7)

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

Design Notes for v 3.3 Board

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

Renard 24 Jumper Settings and Options

Version 2.5 and Greater
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.

Version 3.3 and Greater
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.)

Parts Changes From Board 2.5 to 3.3

With multiple changes to the board, and the changes of parts that has occurred over time, if you still are having an older board to solder up, but still need parts - you can use a current Co-Op purchase for parts if you choose - and you will just have a few extra parts left over (and also still be able to enjoy the significant savings the co-op gets you.)
You will end up with: 2 to 3 jumper sets 2 extra resistors 2 extra LEDs 2 of 71-2828376 - 6 pin connector and 4 of 158-P02EK508A3-E - 3 pin angled connector

On parts 158-P02EHK508V2-E and 158-P02EHK508V3-E - the Five Pin Terminal, it is reccommended to just cut off the pin for one of the plugs.

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:

Version 3.0 Board:

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.

Version 2.5 Board:

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


NOTE: The 2.5 cable will not work with the Renard16, Renard64 or Ren-C boards because pins 4 and 5 on the version 2.5 Renard24 are reversed from those other boards.

Db9f.gif Female DB9 connector as if you were looking into the end of it from the outside.

The Renard24 3.0 or greater will pass the zero cross and power to other boards connected to it (such as a Renard64 or Renard16.)

Errata for Rev 1 PCB -

 1) Onboard regulator not functioning properly: needed addition of 1000uF capacator. (corrected in rev 2.0 board)
 2) Outputs are out of order. (corrected in rev 2.0 board)
 3) Triacs are located to close together. (corrected in rev 2.0 board)

Errata for Rev 2 PCB -

 1) Outputs 17/18 are swapped. (corrected in rev 2.5 board)

Errata for Rev 2.5 PCB - (Co-Op Board)

 1) RS485 traces swapped from the Ren16/Ren64 pin config. (To be corrected in Rev 3.0 Board)
 2) Silkscreen needs to have some clarification done for part orientation.

Errata for Rev 3.0 PCB - (Co-Op Board)

 1) Some holes to small for spade tabs
 2) still some spacing issues around the voltage regulator heatsink.

Errata for Rev 3.3 PCB - (Co-Op Board)

 1) COMM FR LED pads are backwards 

Design Notes for v 2.5 Co-Op Board

Pin 1 of the crystal is on the bottom left.

Pin 1 of the transformer is on the top left.

The cathode (striped) pin of the 1N4001 diode is on the top.

The correct designation of the capacitor on the top right is .1uF, not .1F.

The + pin of the DB102 is on the bottom right both of the ~ should be on the left.

The original parts parts list had a 100uF cap, ignore it - as its not needed (Deleted from BOM) There is a extra 1uF on the board, also not needed.

The 7805 (flat side) goes to the top of the board.

The heatsink for the 7805 should be trimmmed at the bottom to allow for proper fit.

The fuse clips are two tight for the board - now sure how this happened - I need to look into this more - as this is the part that I ordered last year and it fits fine. Use pliers to squeeze the pins together a bit and they will fit in.

The jumpers on the board are for 120/240v operation. If you don't plan on using the boards on 120v these can be hard soldered with a jumper wire.

There are two resistors that are close to the output blocks, when installing them, leave them up a bit so they can be pushed back a little bit.
