here is the picture of the possible setup from the web, but I do have several of such regulators with the support station manifold, actually my personal Co2 work station is such setup with two protocol station manifolds.
for such setup with protocol station(actually a supported manifold), it can be mounted on wall, in the cabinet or fish tank stand, connect to co2 tank with high pressure rating stainless steel hose(normally 3500 - 5000 psi pressure rating).
the multi output post body can be connected to the regulator, one of the reasons such "off the co2 cylinder" setup, the regulator and its bulky post body(multiple output) can be placed to some place more secure, and you can figure out rest of the good reasons depends on your need.
the regulator can be connect to this protocol station directly(undetachable), or through a CGA320 adapter(regulator detachable)
do not have a complete picture of my co2 work station atm, but from these two pictures you can see my personal co2 work station where the swagelok and concoa regulators connect to:
I can work on three co2 systems at the same time.
as Jeff mentioned, the protocol station is not cheap, but all the parts in our high end co2 system are not cheap neither, we can have them build because these parts are cheap enough if we know what and where to find the parts, and last, know how to make them work..
