Default Power-Up State of Reset Line
When a computer with a PCI-AC51 or PCIe-AC51 card installed has just been powered up, bit 0 of
the reset control register will be in its default power-up condition, which is a bit value of zero. This
drives the reset line HIGH and turns LED 1 (reset line) ON.
Reset Configuration of Brains When Using PamScan
One of the parameters you must choose when using the PamScan utility is the reset level of the
brains in your system. Set the option in PamScan to match how your Pamux brains are configured.
PamScan needs to know the brain configuration so that it can determine whether to set the reset
line HIGH or LOW in order to take the system out of reset. This allows PamScan to configure and
control the brains and output modules.
Testing
The following table shows the results of using each of the possible reset settings on the brains and
in the PamScan utility. After choosing the reset setting in PamScan, click Connect to establish
communication with the PCI-AC51 or PCIe-AC51 card and brains.

DIP Switches (PCI-AC51) and Jumpers (PCIe-AC51)
DIP switches or jumpers are provided on the adapter cards for custom implementation and some
Pamux settings.

•
DIP switches and jumpers may be modified on a system that is powered; however, the applications
that use the PCI-AC51 or PCIe-AC51 must be stopped.
Switches or jumpers 1 through 4 are provided for custom implementation. One common use will be
for identifying certain cards in a multiple card system. The settings of these switches or jumpers do
not affect the Pamux operation.

The PCI-AC51 has six DIP switches (the DS1 bank). A switch in the ON position reads as a zero
and OFF reads as a one. The card is shipped with all switches in the ON position.
The PCIe-AC51 has eight jumpers (labeled JP2), of which only the first six are used. A jumper
removed reads as a zero, and a jumper in place reads as a one. The card is shipped with jumpers
removed. (Do not use the jumper group labeled J3. See the diagram on
group location.)
