JUMPERS
In addition to the jumpers already explained in the previous sections,
there are a few other jumpers for use, in more advance debugging applications.
These Jumpers are JP10 through JP15 and are explained here.
JP10, installed at the factory, allows +5V current limiting to function as
specified. Disabling the current limiting function can be done by removing the
JP10 if it is so desired. Extreme caution is recommended. Otherwise permanent
damage can be done to the UUT, the extender board and the system motherboard.
JP11 to JP15 are used for a few selected control signals. In addition to
disabling the signals in groups of 10 via the dip switch, the listed control
signals can also be isolated from the bus on an individual bases.
Since the jumpers are not installed at the factory the extender board has
hard traces connecting these jumpers. Prior to installing any jumpers, the
traces need to be cut. A 2X1 (100 mil) shunt jumpers can be installed at these
locations and when jumpers are removed the signals will be isolated. Signals
controlled by these jumpers are:
JP11 DREQ1
JP12 DREQ3
JP13 IOCHRDY
JP14 DREQ2
JP15 IOCHECK

MODEL PC/AT200
Model PC/AT200 offers an extended PC board area for the user's specific
circuitries. The bus on the component side of this area is connected to the
ground plane. The bus on the solder side is connected to 4 pads marked +V.
Please make sure that you connect the power and ground of any added circuitry
to the appropriate bus. Connect the +V pad(s) to the desired auxiliary output
voltage pads provided at the left of the grid area (i.e. +5V or +12V).
Voltages with "B" reference designations are switched voltages. The other
voltages are directly from the bus.
