I recently purchased several ADC Ultrapatch Patchbays. I'm going to
be installing them in the studio this weekend. I noticed that the
punchblocks have, besides the "T" "R" and "S" connections, two
additional pins, labelled "RN" and "TN." I am assuming that these
stand for "Tip Normal," and "Ring Normal." Is this correct? and, if
so, how does one set these up for full normal, half normal, or non-
normalled?

Thanks

Yes on the RN and TN question. I did a web search for any documentation
that might halep, but found nothing so far.

That sounds right.

and, if so, how does one set these up for full normal,

RN to RN,
TN to TN

half normal,

RN to R
TN to T
If you have it arranged with outputs on top, then the R on top would
connect to the RN on bottom (and T on top to TN on bottom)

or non- normalled?

RN no connection, top or bottom
TN no connection, top or bottom

You are correct on the TN and RN acronyms. Non-normalled is easy -
leave the TN and RN pins alone. For full-normal, connect the TN pin
on top to the TN pin on the bottom. Ditto the RN pins. For half
normal, connect the T on top to the TN on the bottom, as well as R to
the RN. For parallel, ignore the TN and RN pins and connect T and R
instead (one nice thing about punch panels - you can normal very
easily, even between non-adjacent points). This recommendation
assumes that your punch panel and your patch panel have been soldered
straight through and that the whole assembly follows the commonly
accepted standard configuration of top=output, bottom=input.

Peace out,

Assuming the convention of Output = top, Input = bottom:

Input and Output cables are connected to T, R, and S as you would expect.
Connect jumpers to the Input RN and TN. If you want fully normalled
(usually only used for Mic inputs) you will connect these jumpers to the RN
and TN of the Output jack. If you want half normalled, they connect to the
same TR connections as the input cable.

If you are fully normalling Mic inputs you will need to connect the grounds
of the jacks together as well, otherwise phantom power will not get through.
You don't usually need to connect the grounds together otherwise.

********, got that wrong didn't I.

Here's the correction in CAPITALS.
