RJ45 connected vacuum gange heads, such as those from BOC Edwards use a fixed resistor of a certain value to help the gauge controller identify the head used and adjust the display range and voltage pressure curve used. Here presented, is a list of these values and the gauge head that they represent. Note that there are overlaps between manufacturers.
These gauges typically display their signal as 2V for minimum and 10V for maximum pressure.
