cPCI-6840/V Switch and Jumper Settings
The following table lists the switch and jumpers on the cPCI-6840
and cPCI-6840V.
SW1: Reset Button
SW1 is a push-button on the front panel. Pressing SW1 gener-
ates a hard reset.
JP1: Enforce System Enable
The system enable signal (SYSEN#) is located on the Compact-
PCI J2 connector’s C2 position. The SYSEN# is used to determine
the operation mode of the SBC. When the SYSEN# on the back-
plane is tightened to GND, then the SBC will boot as a Compact-
PCI system slot otherwise the SBC will boot as a CompactPCI
peripheral slot.
However, for some “none PCI bus” backplanes, the SYSEN# pin
on the backplane is floating. Install JP1 will short the SYSEN# sig-
nal to GND and enforce the cPCI-6840/V as a system slot SBC.
Please note do not install JP1 when the cPCI-6840 is installed in a
peripheral slot of CompacPCI system.
