Sensor Signal Distribution (Distro) Cards

So here is the deal:  SR and HSR Classic (7050) distro card need Classic ribbon cables; on the other hand Classic ESR, CEM + and CEM3 use the 7070 distro cards and the new cables. They cannot be interchanged- they are wired differently.  If you have an upgrade kit to CEM + or CEM3 from Classic you get an adapter card that allows the classic  distro card and cable to be used in a CEM+ or CEM3 enclosure.  If there is a distro card failure in an upgraded classic rack, just replace the distro card with a new 7070 and the new cable. The only time  a 7050 distro card should be needed is in a rack that still has a Classic CEM in it.  Expect for ESR classic that is…
