| Looking at the top of station1. The cables 1-4 go to the 
first ROC board, the next 4 to the next ROC. At this end, cables
1 and 3 are shorter than cables 2 and 4 by 19 mm, and the distance from the 
center of the HV connector to the extension cable end is 14.5 mm. In this view:

| Assume the bias cables follow the same path as the extension cables. Note that bias cable 2 follows the straight extension cable that is highlighted, so we can use it's length for part of the bias cable path. This is cable 111-PHX-02-3201.PDF, length 280.3 mm. On the HDI end, the distance from the center of the HV connector to the end of the cable is 14.5 mm. |   | 
| On the ROC end, the distance from the cable end to the bias connectors
is AB minus the distance from the connector's center to the cable end, which is
193-8.7 = 184.3 mm.
