<DIV><FONT face=Arial size=2>That's good to know. i was thinking as well of some
kind of wireless video sender/receiver for each camera. So I can move them
around and change their position easily. I dont know whether someone tried this.
I dont know either whether have some of this devices interfere each other or
with wireless (802.11 I mean) or Digital TV signals...</FONT></DIV>

<DIV><BR></DIV>Natalia,<BR><BR>I need to get you a picture of how the cables
are placed on ours (maybe I'll take the top off and show you that way) - but
basically, I have a set of cable ends from the phoenix connectors on the
XAP400 that just run to the back in a flexible conduit with XLR connectors
where the cables (which are coiled up on hooks on the sides when in
"storage/move mode" and simply plugged into the connectors on the back when in
use. This lets me mix and match for distances, etc.<BR><BR>Note: a lot of 2"
wide velcro was used in keeping things in place - monitors, gentner (helps
cushion during travel as well), other devices - even the powerbricks from the
monitors, etc). Walmart, fabric section - black or white is where you find
lots of the stuff... =)<BR><BR>I'm setting up the system over the weekend for
a conference, i'll get some detailed picture for you on that. My preference
would have been to put a patch panel somewhere on the cart but just never got
around to it - i.e. it works, it's quick, we've been so busy I haven't done
more to it! But it could be cleaned up.<BR><BR>Someone was telling me that the
audio folks have some nifty cards for rackmounting equipment that are
mobile... i have to look into that... they did say it was $$$$
though...<BR><BR>-John Q.<BR>-- <BR>John I. Quebedeaux, Jr.<BR>Louisiana State

<BLOCKQUOTE><BR><BR>Natalia,<BR><BR>I hate to say it this way... but it
depends. That's one of the things about the AG is that it IS so flexible for
the environment you are putting it into. Will you use the portable in a
small room, large room, auditorium, etc? everywhere?<BR><BR>I'm currently
upgrading our portable node and putting as much flexibility and power into
as small a box i can get was one of my dilemmas. I'm still looking at
motherboard slot configurations, etc. I'm going to be trying out one of
those quad-capture cards... <BR><BR>However: this is what my current
portable node looks like below (LSU's portable node is affectionately named
"Wilbur the PIG")<BR><BR>two 15" LCD monitors<BR>one dual head AGP Matrox
card (I forget which)<BR>one quad head PCI Nvidia card (I forget
which)<BR>two Canon VC-C4 cameras<BR>one Sony EVI-D100 camera<BR>3
tripods<BR>wireless keyboard and mouse<BR>one trackerpod quickcam (WDM) for
operator<BR>three osprey 100 capture cards<BR>on board audio/network
(100mbit on this one)<BR>CPU is a dual 2.2 xeon running
XP(SP2)<BR>XAP400<BR>one wireless lapel mic<BR>i borrow crown mics from my
full node as needed for inputs 2-4<BR>pair of genelec 1029A
speakers<BR>surgeprotector/filter<BR>50' to 100' of just about every cable -
well shielded s-video cables btw.<BR><BR>my upgrade will speed up the
CPU/motherboard, replace the video card with a single quad card, put in a
single capture card, have audio and firewire and gigabit. I'm going to add a
2nd wireless mic (for audience on a stand) and a couple of table mics I can
attach. I'll upgrade the cart - pneumatic tires probably or build a split
"cart" where the top and bottom are removable for easier travel in vehicles.
I've taken Wilbur all over the state. Fortunately, this design fits in the
back "well" of my van (where the back seat folds up into). Note, the tripods
do fold up small enough to fit inside the cart. EVERYTHING fits on the
cart.<BR><BR>The bottom half of this card holds ALL the cameras, cables,
etc. The top half holds the CPU, echo canceler, wireless receiver, monitors,
and speakers (velcro holds them in place during the long rolls across
campus). There is even a plastic cover (see picture with umbrella in the
corner?) that keeps it dry in the event of a sudden down pour (which has
happened... it's Louisiana, thunderstorms happen). =)<BR><BR>The reason for
the mismatch on the cameras is that i ended up with a spare camera from
another project... and two cameras is NOT enough. I'll even say 3 isn't, but
3 is okay. <BR><BR>The cart is a rubbermaid cart... we removed the drawer
section in the top half, put a plywood board in for more support (that CPU
is heavy), and cut one small hole for the cables into the bottom half where
we have a powerstrip/surge protector.<BR><BR>Hope this gives you some ideas.
Basically though, this has allowed most of the flexibility I needed - I have
a spare projector but it's not that bright and i have to rely on the
installed projectors in rooms I go to, but 1 projector isn't enough (no one
seems to understand that until they see our full node in action). They keep
wanting to squeeze everything into one screen. Argh. Terrible.<BR><BR>-John
