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
  • 1 MAX485 IC or ST485BN IC (8-pin RS485 transceiver)
  • 81 pin8-pin dipDIP socket
  • 1 2x10 2.54 pitch male pin header
  • 4 shuntShunt jumpers
  • 1 100nF Ceramic Disc Capacitor
  • 1 470uF Aluminum Electrolytic capacitor (Optional)(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
  • 1 PCB Mount 8p8cRJ45 (8p8c) (top or side entry) (optional)
  • 1 1x2 right angleright-angle 2.54 pitch pin header
  • 1 1x2 straight 2.54 pitch pin header
  • 1 151x15 right angle 2.54 pitch pin header (male or female)


Install the 10k Ohmohm Pulluppull-up resistor

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

install Install the 100nf Ceramic disc capacitor

install Install the 15 pin15-pin male right angle header and optionallyoptionally, if you are connecting to a RF1 12V12V, add the 2 pin2-pin right angle header
Install the 2x10 pin header IFif you are going to power the board over serial (cat(Cat5 5 pinPin 3 can power the RF1 7.5-12v) if7.5-12v). notIf not, you dontdon't need to install the 2 pin2-pin male header shown here.
install Install the big polarized capacitor (note the orientation)
Install the RS8-pin 485DIP chipsocket

You need to put jumpers on the pins as indicated for your serial type type. Renard, DMX,DMX and LOR are supported If you are going to provide power over serialthe Cat5 cable, you can supply 7.5-12v on RJ45 pin 3 and add an extra jumper on the VIN Enable headerheader.

note:Photo shows shunts in DMX mode position jumpers mode.


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.)
