[Dsg-mvt] MVT gas mixing electronics/network equipment

Thu Oct 12 14:06:25 EDT 2017

The network cable should be a CAT6 Ethernet cable.  If it will be running next to any strong electrical interference, then it should be a shielded CAT6 cable.  If any part of the run will expose it to the sun, the outer jacket will need to be outdoor-rated (UV-protected).  Don't get a gel-filled cable - since it won't be direct-buried or submerged in water, you shouldn't need it and it is a pain to terminate.

Do you know where the cable will terminate within Hall B?  I'd like to make sure we have a switch close to that location that can provide the networking you need.
