Ren24DC Construction Manual
What is the Ren24DC?
Revision History
6 Port E1.31 Bridge Parts
To build the Ren24DC, you need 4 things:
- The PCB
- The parts to solder on the board, also known as a BOM (Bill Of Materials).
- A power supply to power the board. The board can use any 5-24VDC power supply.
- An enclosure to mount the finished board in. Commonly used enclosures include the CG-500, CG-1000 or the CG-2000 which are available from several vendors
The BOM parts needed to build the board are:
Mouser BOM | |||
Part ID | Mouser PN | Description | Qty |
R1 | # | Resistor | 3 |
You can buy the parts directly from Mouser: Click here for Mouser Direct Project BOM
or
The BOM is also available at a discount in a kit that includes the PCB from DIYLEDExpress.com
Building the Ren24DC
The Ren24DC requires a fair bit of soldering so take your time and ensure you install the components in the correct orientation when required. Start by sorting the components by type and values. Look over the PCB before starting noting the location of the various components. Follow the standard procedure of installing the lowest profile parts first and ending up with the tallest. You can click on any photo to see a larger version of the image.
- □ 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 boards.
Congratulations! That completes the construction of the Ren24DC!
Jumpers
JP1 - DMX Termination
Install shunt to terminate DMX input
JP2 - RS232 Mode
Install shunt for RS232 input
JP3 - Data Mode
Normal Operation Jumper Pins 1/2 on both rows Thru Operation Jumper Pins 2/3 on both rows
JP4 - Power Jumper
This jumper is used if you are supplying either a well regulated +5v or unregulated +7-24v. If you apply +5vdc to the terminal block, you should put the jumper on the "EXT" setting (indicating you are getting 5v externally). If you apply +7-24vdc, you should put the jumper on the "INT" setting (indicating you are getting 5v internally via the 5v regulator).
You MUST ensure you have this jumper set correctly if you are using voltages greater than 5v as it may (and probably will) cause permanent damage to some components on the board.
JP5 - Wireless Header
Install shunt on pins 4/5 for normal operation. Pin 1 - +5V Pin 2 - No Connection Pin 3 - GND Pin 4 - Data From RS485 Pin 5 - Data To PIC
Powering the Ren24DC
Initial Testing
TroubleShooting
So - you've built your new Ren24DC, connected it up to your computer and tried a quick sequence and nothing happens! There are several checks to perform in order:
Visual Inspection
The very first step involves a close visual inspection of the board. Double check that you have the correct component in the correct location and in the correct orientation. Look at every single solder connection and if some are not shiny or look suspect - reflow them to be sure.
Power
Measure the voltage supplied to the Ren24DC and ensure it's either +5vdc or +7-24vdc and ensure the power jumper is set correctly. Measure the voltage with the supply plugged in and connected to the Ren24DC to ensure it's not shorting out. If the voltage is correct then you know the input level is correct.
Remove any/all socketed chips from the board before proceeding.
