To test the HP E3491A Pentium Probe
If this is the first time that you have used the E3491A Pentium Probe, you
should run the built-in performance verification test before you connect to a
target system. Refer to chapter 5 for information on performance verification.
To connect to a target system via the Intel defined
debug port
If the target system has been designed with the Intel defined 20- or 30-pin
debug port, the HP E3491A Pentium probe should be connected to the
target system using one of the 20- or 30-conductor cable assemblies
provided.
1
Remove power from the target system and the probe.
2
Plug the adapter board in the E3491A Pentium Probe.
3
Plug the 30-pin connector end of the 20- or 30-conductor cable
assembly into the adapter.
4
If you are using the 20-conductor assembly, plug the 20-pin connector
end of the cable assembly into the 20-pin debug port in the target
system.
5
If you are using the 30-conductor assembly, plug the 30-pin connector
end of the cable assembly into the 30-pin debug port in the target
system.
Note that pins 21 - 30 are not used by the HP E3491A; the probe does not
support the dual processor capability of the 30-pin debug port.
6
Turn on the power to the probe, then turn on the power to the target
system.
