1. Introduction to Renard
Renard is the name of a “do-it-yourself” (DIY), computer-controlled, PIC-based dimmer light
control concept. It also refers to a family of dimming controllers that have been designed and built
based on this concept.
The Renard design concept was originally described by Phil Short in the Simple PIC-Based 8-Port
Dimmer 'How-To' on the http://computerchristmas.com website. Since then there have been many
enhancements and new designs based on this hardware. There have been many contributors to
advancing Renard technology including M. Macmillan, D. Davis, P. Rogers, T. Straub, D. Haberle,
A. Williams and others.
Renard controllers typically rely on a separate computer running a light sequencing program to
send it real-time sequences of controller commands to sequence the lights. The computer
communicates with the Renard via RS232, RS485, or wireless (depending on the design) and the
Renard controls the lights either through built-in power control (power is output directly to the
lights), or via separate “SSRs” (solid state relays supply the power when commanded by the
controller).
Example Renard configurations
Output of the Renard can be either control signals (to an SSR), direct AC line voltage (110,
100/220, or 220), or DC voltage depending on the design.
Renard is a DIY hobbyist effort and there is a vast amount of products and related peripherals to
select from including the Renard Plus 32 Controller. To obtain a specific design, there might be
“buy a parts kit and/or blank PCB” offering at a site (such as from www.renard-plus.com), “etch it
yourself” files for true DIY, or coop/group buys for kits and PCBs also in forums (like
DIYChristmas.org).

2. Overview of Renard Plus 32
This guide covers the Renard Plus 32. This board is designed to take “Renard” serial
communications via RS485 from a control computer, and output full diming light control on its 8
RJ45 Renard SSR (each capable of driving up to 4 channels). These outputs typically connect to
up to 8 solid state relay (SSR) modules each with 4 channels of outputs for a grand total of 32
individual controllable/dimmable channels. The SSR controller can be any of a variety of SSR
modules which might control AC (like the DirkCheapSSR) or DC (like the LabRat DCSSR) or a
combination thereof. The type of light you want to control will dictate the type of SSR you choose
to use.

3. Assembly Instructions
This section covers the construction of the Renard Plus 32 controller board. It approaches these
tasks as a learning exercise for new builders, so that they can develop proficiency and self-
confidence. The project itself is quite simple and if you follow the steps carefully, you should have
a working controller when you are done. Additional information and guides on techniques and
tools can be found in the “Tools and Parts ID Guide” at:

3.1.2 External ower su ly
There is also an option to use external AC power from 8 to 12 volts AC supplied from an external
power supply such as an AC wall transformer or “wall wart”. If you opt to use an external AC power
supply instead of the onboard transformer, please follow the following steps:
1. Make sure you use an AC power supply (like a “wall wart” type adapter) in the voltage range
from 8 to 12 volts AC. Note: the wall wart MUST be AC, the more commonly found DC wall
warts will NOT work.
2. Make sure you do NOT strap both the “115” and “230” voltage selection straps.
3. Use two lengths of 22 or 24 gauge wire to connect the following:
a. Transformer pad pin 8 to left most “115” strap option RIGHT
pad. Follow the dashed line labeled “Wall Wart” on the
silkscreen.
b. Transformer pad pin 7 to transformer pad pin 1. Follow the other
dashed line labeled “Wall Wart” on the silkscreen.
4. Connect the two output wires from the AC wall wart to X1 (the AC input
connector on the top right of the board).

3.2 Parts Assembly
The Renard Plus 32 is a simple device to assemble and test. It is easiest if you build the units by
inserting the various components from smallest to tallest.
3.2.1 First Things First
1. Begin by inspecting the PCBs to look for any defects such as cracks or breaks. The holes
on the board should be open on both sides. Then inspect and sort out the various parts for
the board.
2. Next inspect and sort out the various parts for the board. Make sure you understand which
parts are which, and things like resistor codes and component orientation. A separate
document on these concepts is available at:
www.renard-plus.com/files/Tools_and_Parts_ID_Guide.pdf
and on other resource sites like Wikipedia.
3. Follow the assembly guide as follows in the next section.

3.3 Renard Plus 32 Assembly Guide
3.3.1 Set Voltage O tion
The boards have the option of running from either 115VAC main, or 220VAC with the
recommended on board transformer option. Jumper straps set the desired main AC voltage into
the board at X1. It is important to only strap EITHER the two 115 options or the one 220 option.
Note the 115 options are strapped individually, and should not be connected to each other.
Step Instructions Renard Plus 32
1a 
110V
Option
If the controller will be used for
115 volt AC
configuration use 2 leftover clipped leads and
form them to individually jumper each of the two
115 pad sets near the transformer. Solder.
Note: Each set of the two 115 options have
individual jumpers and do NOT connect to each
other.
DO NOT JUMPER both 230 and 110 voltage
pads at the same time!!
1b 
220v
Option
If the controller will be used for
220/230 volt AC
configuration use 1 leftover clipped lead and
form them to jumper the 230 pad near the
transformer. Solder.
DO NOT JUMPER both 230 and 110 voltage
pads at the same time!!
If you will NOT be using the on board transformer option, but wish to supply 8 to 12 volt AC from
an external supply, such as a wall transformer or “wall wart”, please leave these straps off, and
refer to the Transformers sections for details on using external AC.

3.3.8 Initial Testing / Final Assembly
At this point you have completed the assembly of the board and you should gently clean the board
of any residue and inspect for solder bridges or cold solder joints. What you are looking for are
any solder bridges especially around the IC’s and other closely spaced parts, or pins that are not
fully and cleanly soldered.
If you have any of the IC’s (IC1, IC2, IC3) installed – remove them now.
Connect a line cord (either 115v or 230v) to the X1 terminal (115/230 VAC).
Warning
High Voltages Present
When you plug in the controller verify the power LED lights up. Verify you have 5v between pins
11 and 12 on the PIC socket as well as between pins 1 and 4 on the 485 chip socket.
If the voltage does NOT measure +5, remove power and start troubleshooting. Look for solder
bridges around the bridge rectifier, or regulator. Double check the regulator number to make sure
it is what you expect (something like LM7805 or LM340T-5). Verify the transformer is installed in
the correct orientation. Check the Voltage Selection straps for the correct selection. Look for cold
solder joints – retouching all solder connections, especially in the power supply area, will often
help solve issues like this.
When power measures good, turn off your power supply and continue assembling.

4. Final Ste s
At this point you will have now completed the installation of all of the parts to the controller. Again,
it is a good idea to gently clean off any final soldering residue and then visually inspect the board
and check to make sure there are no solder bridges between the solder pads, and that the solder
joints are all a good quality.
4.1 Programming the PIC
Note: The Renard Plus controllers do not use the original Renard firmware used on other
Renard devices. Make sure you use the Renard Plus version of the code from the Renard-
Plus.com website!
Programming the PIC can be done with the PIC chip plugged into a PIC programmer such as the
PICStart from MicroChip or onboard using a programmer like a PicketIII or PicKit2. Programming
PIC’s using standard assembly is written up in the PIC Programming Manual available on
www.renard-plus.com.
4.2 Jum er Settings / Headers
4.2.1 JP1 XBee Header
This header can be used to connect a XBee Wireless module directly to the Renard Plus 32 using
a Xbee Snap-in board or indirectly using 3 or 4 wires to a board
such as the REN-W. If you are not using XBee Wireless then you
must jumper pins 4/5 using a shunt jumper. The following are the
pinouts for the Xbee header:
Pin Layout
1 = +5VDC
2 = N/C
3 = GND
4 = RX from 485 chip
5 = RX in to PIC
Option - Xbee using Snapin Board
Note: When assembling the DIGWDF Xbee SnapIn board (http://diychristmas.org/store/) install
the female 5 pin header block on the bottom side of the board. Once assembled the SnapIn
board can only be plugged in one direction.
4.2.2 JP2 PIC By ass / DMX
If you are using Start Address Programming, you can use the PIC bypass to allow the data to flow
thru the Renard Plus 32 without the usual Renard "address eating". If you use a jumper across
pins 1/2 then the data stream that comes into the device goes out
exactly as it came in with no addresses consumed by the Renard
Plus 32. The default position is a jumper across pins 2/3.

1 = Data In From RS485 IC
2 = Data Out to RS485 IC
3 = Data Out from PIC

4.2.3 JP3 RS485 Terminator
There are situations where the communications from the
computer might require termination. Usually line reflections or
other environmental conditions might disrupt communications to
the controller. You might see missed light transitions, jumpy
animation, or complete no operation. In this case, adding
termination *may* return reliable communications assuming
everything else is working right.
4.2.4 Programming (ICSP Header)
This header allows the PIC to be programmed while the PIC is installed on the board. The
following are the pin-outs for this header:

Pin 1 = MCLR
Pin 2 = +5 volts
Pin 3 = GND
Pin 4 = PGD
Pin 5 = PGC
Pin 6 = PGM/RB5
