A Quick Lesson on Soldering
Soldering is a skill that is only learned through practice. If this is your first time soldering a circuit board,
take the time to read over these steps and practice on a spare or practice PCB. The ability to solder
properly could determine the lifespan of the product and how well it functions. Below are a few
pictures to help guide you in your understanding of soldering.
With this kit, you will need to provide your own solder. Do not make the mistake of using plumbing
solder or acid core solder. This type of solder will damage the PCB and cause the unit to become
useless. Thin, rosin core solder is designed for use with electronics
and should be used for this application. A local electronics store or
RadioShack will sell this type of solder.
To begin, be sure that the circuit board is clean and all the traces
are intact and not broken at any point. Also be sure the soldering
iron is fully heated and the tip is clean. Having a sponge or a Tip
Cleaner (pictured) nearby is very useful.
When inserting components into the circuit board, be sure to bend the
ends just a little bit to hold it in place. This will allow you flip the
circuit board over and have the component held in place while you
solder.
Next you should place the tip of
the soldering iron directly on the
board foil of the circuit board, next to the component lead. Allow
the heat to transfer and touch the other side of the lead with the
solder. The solder should flow evenly onto the lead and the foil
making a good connection. It is very important to make sure you
are applying heat to both the component and the board foil. If just
the board foil is being heated, then the solder will not hold to the component. At the same time, if just
the component is being heated, then the solder will not hold to the board foil.
Once the solder has cooled, use wire nippers to cut the remaining component leads up against the
solder.

Part Description
1.1 USB Interface IC
The USB Interface IC is used to connect the dongle to the computer’s USB COMM Port. This device
is extremely small and a SMD. Most novice electronics builders do not have the ability to properly
solder these small devices. Whether you purchased this kit fully assembled or a DIY device, this chip
will already be soldered onto the PCB.
1.2 Resistors
Resistors are specified by their resistance value in ohms. On this particular product, there are four
different resistors used, at different values. The polarity or way the resistors are inserted into the
board does not matter, as resistors do not have a polarity. Make sure that the resistors are placed
firmly up against the circuit board and the leads are cut as close to the solder as possible. Be sure to
read and understand the markings listed below to insert the proper resistor in the proper location.
1.3 Capacitors
A capacitor, when taken down to its bare roots, stores electricity. Because of this, it is very
important to understand a capacitor’s orientation on the PCB. The circuit board has a printed “+”
marked next to a square solder pad. Be sure to align the minus/plus on the capacitor with the
equivalent marking on circuit board. If your capacitor only has the minus marked, then put the
unmarked lead of the capacitor in the “+” hole. Usually the capacitor has a gray line down one side.
This is the negative side. This project also uses capacitors that do not have a polarity. It does not
matter how these are installed into the board. You should install them the same way you install a
resistor.
1.4 RS485 Interface
The RS485 chip translates the signal received from your DMX network and puts it into a language
that the controller can understand. There is only one of these 8 pin chips on this board.
1.5 Crystal
The crystal on this board is used to regulate the speed of the transmission of the DMX signal.
1.6 EMI Filter Bead – Ferrite Bead
A ferrite bead is used to suppress high frequency noise on a data line. These devices help prevent
interference with data going in more than more direction. There is one bead used on this device. It
has no polarity so install it like you would a resistor and trim the leads on the opposite side of the
PCB.
1.7 Optocouplers
Optocouplers are a safety device that are used to isolate the higher voltage used to control the
lights with the lower voltage used in your computer. Without these devices, in the event of a sort,
that power could travel back to your computer and fry some of the components in your computer,
or worse, your entire computer. There is no actual physical electrical connection in this device,
which is how the isolation is done. Be sure to match the notch or dot to the notch on the silkscreen.
1.8 MOSFET
A MOSFET acts as an on/off switch for the voltage. However, with the electronics on the board the
www.seasonalentertainmentllc.com
switch can be faded on and off very easily and smoothly. These particular MOSFETs are in the TO-92
shape. These are much smaller than standard MOSFETs and allow us to keep the board small. Be
sure to insert them into the board according to the silkscreen
1.9 Integrated Circuit
The Integrated Circuit (IC) in this kit has already been programmed. Located on the processor is
either a notch or a dot stamped or printed on the IC. This will indicate which pin is “Pin 1.” Printed
on the circuit board is a silk screen showing which direction the notch should face. It is very
important to orient, not only the IC, but also the socket correctly.
1.10 LEDs
LED’s have two leads. The longer of the two leads is the positive side of the LED and should be
inserted into the round hole on the circuit board. This kit uses two 3mm LED which are smaller than
standard LEDs. The LEDs should be installed higher off the board so they can be bent to fit into the
enclosure
1.11 Modular Jack
A modular Jack is a component used to easily connect Cat-5 cable to any device. All internal wiring
is completed and the device is ready to be installed into your circuit board. Be sure that all 8 pins
are inserted into the circuit board before pushing the black tabs into the holes.
1.12 Sockets
This kit uses sockets to easily insert and easily remove IC Chips. The sockets used in this kit are 8 pin
and 28 pin sockets. The pins on the sockets are bent to hold them onto the PCB until they are
soldered in placed
1.13 Header
This design uses one 6 pin header used to connect a programming header to update the firmware
on the controller. There is no orientation and the header can be installed any way you wish.
1.14 DC-DC Converter
The particular DC/DC Converter used in this product is a fully isolated converter. This allows a
complete electrical separation between the electrical components on the device. The DC/DC
Converter used on this board is rated at 1000 volts. The leads may hang low after soldered so if they
do you should cut them off.
1.15 3 Pin XLR Jacks
This product uses 3pin female XLR jack. This jack is needed if you plan on using any sort of XLR
connections to your DMX devices
1.16 USB-B Right Angle Connector
The dongle receives its power and data from a USB-B cord. The cord connects to a right angle
connector. There are 4 data pins and 2 mounting/grounding pins. Be sure they all get installed and
soldered to the PCB
1.17 Enclosure and Screws
This product comes equipped with a black anodized aluminum enclosure. This enclosure features
two different end plates and all the screws necessary to attach the end plates. Further instruction
on installing that circuit board in the enclosure can be found below. There are also two additional
screws to attach the XLR jack to the enclosure.

Enclosure Installation
Before installing the completed xDONGLE into the enclosure bend the red and green LEDs so
they are parallel with the PCB. This will ensure they
slide directly into the enclosure.
Push the completed
xDONGLE PCB into the
enclosure using the last
grove, nearest the bottom.
Push it all the way through
until the XLR and Cat-5 jack
is sticking out. You should
not need to force the PCB
into the enclosure. If it is not going in correctly, check to make sure
the XLR and Cat-5 jacks are matching their holes correctly.
Now that the PCB is installed in the enclosure, simply attach the
four remaining screws for the end plate. Next, use the two included
screws to firmly secure the XLR jack to the end plate. Once all
screws have been installed assembly is now complete.
