+<!-- l. 57 --><p class="noindent">If you are reading this, chances are you have become an unfortunate test subject of the RBUS-ADAT conversion
+board (or have the nerves to think about becoming one). Well, here is (almost) everything you will want to know
+about the board. If you want to learn about some less useful information about this thing, consider checking out
+the devlog, which can be found by following the link to the project homepage listed under “Useful
+links”.
+</p><!-- l. 64 --><p class="indent"> As this manual is written as if it’s a blog post, which is prone to being very rambly, I’ll try to keep the rambling
+low, at least make an attempt to do so.
+</p><!-- l. 67 --><p class="indent"> Pictures in this manual are renders (computer-generated) and are for illustration purposes only.

+<!-- l. 105 --><p class="noindent">There’s no enclosure for this board. As a result there would be exposed conductors on both sides of the board.
+You’re advised to take measures to prevent them from shorting out. You may try any combination of the
+following:
+</p>
+ <ul class="itemize1">
+ <li class="itemize">
+ <!-- l. 110 --><p class="noindent">Placing the board on an non-conductive surface.
+ </p></li>
+ <li class="itemize">
+ <!-- l. 111 --><p class="noindent">There are two M2 mounting holes in the board. Using two M2 screws and nuts, install a plastic sheet
+ (or cardboard even) under and / or over the board.
+
+
+ </p></li>
+ <li class="itemize">
+ <!-- l. 113 --><p class="noindent">Don’t use the board at all. Don’t even think about it.</p></li></ul>
+<!-- l. 116 --><p class="indent"> Again, if you fried your equipment while using this board, it’s all your fault. I mean not really – I would still
+want to know what happened. But it’s all your fault.

+ <h2 id="tocanch4" class="tvis"><span class="titlemark">5 </span> <a id="x1-50005"></a>Intended usage and applicable devices</h2>
+<!-- l. 124 --><p class="noindent">RBUS-ADAT is designed for use with the Roland XV-5080. It converts the 8 digital outputs exposed by XV-5080’s
+R-BUS port to a standard ADAT lightpipe stream which can be recorded with any audio interface with an ADAT
+input.
+</p><!-- l. 128 --><p class="indent"> The ADAT output from this converter is 20-bit and has the same sampling rate as the input supplied from the
+R-BUS port.
+</p><!-- l. 131 --><p class="indent"> This converter <span class="ec-qplb-x-x-109">cannot</span>:
+</p>
+ <ul class="itemize1">
+ <li class="itemize">
+ <!-- l. 134 --><p class="noindent">Convert ADAT back to R-BUS input. i.e. you can’t record an ADAT stream on a V-Studio through
+ R-BUS with this converter.
+ </p></li>
+ <li class="itemize">
+ <!-- l. 136 --><p class="noindent">Serve as a clock source for the connected R-BUS device. You should always select “internal” as the
+ clock source for the connected R-BUS device.
+ </p></li>
+ <li class="itemize">
+ <!-- l. 138 --><p class="noindent">Expose the MIDI interface on the R-BUS port.</p></li></ul>
+<!-- l. 141 --><p class="indent"> The converter is designed and tested with the XV-5080. In addition, the only audio interface that
+has been verified to work is Focusrite Scarlett 18i8 3rd gen. I don’t have the resources to test other
+devices.
+</p><!-- l. 145 --><p class="indent"> The converter has not been tested against VM- or VS- devices that feature RMDB 2 / R-BUS ports
+or MV-8<span class="cmsy-10x-x-109">××× </span>fitted with the MV8-OP1 expansion but may still work as a unidirectional converter
+as intended. If you decide to try this converter with these devices, reporting the results would be
+appreciated.
+</p><!-- l. 151 --><p class="indent"> The converter is not compatible with devices with the older RMDB port.
