RS485 Serial DMX / Renard Adapter Assembly Instructions

Instructions for the newest Serial Adapter Board only. For other PCBs see RF1 Serial Adapter Rev 0.2 Assembly Instructions


  • 1 Serial Expansion PCB Version 0.7
  • MAX485 IC
  • 8 pin dip socket
  • 2x10 2.54 pitch male pin header
  • 4 shunt jumpers
  • 1 100nF Ceramic Disc Capacitor
  • 1 470uF Aluminum Electrolytic capacitor (Optional)
  • 1 1/4w 120 Ohm Resistor
  • 1 1/4w 10k Ohm Resistor
  • 3 1/4w 1K Resistors
  • 1 3mm yellow LED
  • 1 3mm green LED
  • 1 3mm red LED
  • PCB Mount 8p8c (top or side entry) (optional)
  • 1 1x2 right angle 2.54 pitch pin header
  • 1 1x2 straight 2.54 pitch pin header
  • 1 15 right angle 2.54 pitch pin header (male or female)


Install the 10k Ohm Pullup resistor

Install the 120k Ohm termination resistor
Install the 1k Resistors - these are for the LEDs and are not needed if no LEDs are used
Install the DIP socket for the RS485 chip and the LEDs. The LEDs are polarized note that the flat side is to the left of all leds. LEDs are optional.

install the 100nf Ceramic disc capacitor

install the 15 pin male right angle header and optionally if you are connecting to a RF1 12V add the 2 pin right angle header
install the 2x10 pin header IF you are going to power the board over serial (cat 5 pin 3 can power the RF1 7.5-12v) if not you dont need to install the 2 pin male header shown here.
install the big polarized capacitor (note the orientation)


If you are setting a start address in the RF1 sketch then you should set your controller to start at address 1 (LOR, DLA and probably all other DMX controllers.) or 0 (Renard Addressable, or don't use start address firmware.)
