Manual

http://falconchristmas.com/wiki/images/UAmp_Owners_and_Set-up_Manual_1.2.pdf

Key note for the manual - all wire colors shown are for illustrative / demonstration purposes only.  Your color scheme may be different.

In V1.1:

Added some detail on a "high current bypass" (HCB) mode where only small tap wires are used to power the microamp.
Added discussion on placement
Made some general revisions and clean-up

In V1.2:

Additional grammatical and sentence clean-up


Demonstration Video




What it is / What it does




At the basic level, the Micro Amp is a signal conditioner / amplifier which can be used with any square wave data source.  The uAmp has been designed using the same MOSFET drive technology as the uSC and has some of the same design features such as built in strain relief holes, basic board comes pre-assembled and ready to use, pre-formed holes for optional LEDs (indicating 'power' and 'data out'),  compact size, ESD protection and short circuit protection on the data line.

Unlike the uSC, the uAmp is solely a digital signal processor.  It has no PIC chip and is not capable of differentiating different 'channels' of data the way a string controller does - it simply processes, clarifies and amplifies ANY data fed to it.  Conversely, it is a simple 'plug-n-play' device.  No PIC programming, firmware, channel setting, etc is required.

This example shows the data output of an SSC in blue (which is also used as the input for the uAmp).  Instead of a clear 5V square wave, the data shows substantial 'ringing' and only averages barely over 3 volts at the top of the square wave.  The uAmp is capable of clarifying this data and boosting the signal to nearly a full 5 volts as shown in yellow - which is the uAmp output).  Ringing is substantially dampened and the square wave data shows crisp on/off transitions.



Some possible uses:

If you wish to send data from an unmodified SSCV1 or SSCV2 more than a few inches, or an SSCV3/V4 more than a few feet, a uAmp can be added to the output line.  Once installed, the low power, 'messy' SSC data is amplified and clarified so the controller can now be 50, 60, 70 or more feet to the display element.

[SSC] <few inches> [uAmp] <........................................50+ feet............................................> [Node]...[Node]...[Node]...



"Null Node" - Data transmission between nodes is limited to around 6-15 feet (regardless of string controller*).  Installing a uAmp after a node will condition and boost the data signal strength so gaps between elements can be 50, 60, 70 feet or more if needed.  Because the uAmp processes data and does not use the "take one and pass it on" format a node does, the uAmp does not need to be programmed into the display as a null node does.

......Data......[Node] <few inches> [uAmp]<...................................50+ feet.......................................> [Node]...[Node]...[Node]...


*Note - The data stream is regenerated and retransmitted by each node.  Due to this a controller with a strong output (such as the uSC) can send data quite a far distance to the first node, however, when that data is retransmitted by the first node, the distance is again limited to around 6-15 feet.   



"Multiply" a single data stream - Since the uAmp has very high input impedance it does not put considerable load on the data line so multiple uAmp boards can be added to even a weak data stream.  If you wish to have multiple display elements showing the exact same data/colors, multiple uAmps can be tied to the same data stream.  Each uAmp will then deliver its own high power data stream for use with display items.  You would not need to use a separate uSC or SSC for each element, though you may need to take appropriate measure to insure adequate power delivery for the nodes.

                    [uAmp]<...................................50+ feet.......................................> [Node]...[Node]...[Node]...
.....Data...... [uAmp]<...................................50+ feet.......................................> [Node]...[Node]...[Node]...
