Notes for Figure 10.1-1.
[1] Notes explaining the functions of the various jumpers on jumper header connectors J2, J5 and J6 are given
below in left to right order of jumper position. The term "default" means as standard OEM units are
configured when shipped from factory. "Off" means no jumper is installed; "On" means a jumper is installed.
Off or on underlined is factory default condition.
[2] "ND" models do not have terminators on the drive PCB, so these jumpers are not applicable.
[3] Reserved usage. Do not install a jumper.
