Only one range can be selected at a time. The input channels can only be
programmed for specific gains within the selected range.
2.6.4.2 Fixed Gains (Jumper-Selectable - version 1 only)(J6, J7, J8, or J9)
The fixed gain for each analog input channel in the version 1 of the XVME-500/590
is selected by installing or removing one of several jumpers (J6, J7, J8, or J9).
Gains can be selected from one of four different levels as follows:
Level
Gain Selected
I (Unity Gain) x l
2 x10
3
xl00
4
xl000
Only one gain factor can be selected at a time.
The input channels can only be
programmed for a specific gain range.
Thus, when a jumper is installed to achieve
a particular gain, others must be removed. Table 2.9 shows which jumpers are used
to select which gains.
