HP E3491A Pentium Probe—At a Glance
The HP E3491A Pentium Probeprovides
a low-cost way to debug embedded
softwareforIntel Pentium
microprocessors. It can also be used
with theHP E2457A Preprocessor
Interface for microprocessor code
disassembly.
Thetargetconnection
The HP E3491APentium Probe connects
to your target microprocessor via a
special connector onthetargetsystem,
or through the HP E2457A Preprocessor
Interface.
The HP 16505A connection
The HP E3491APentium Probe connects
to theHP 16505A Prototype Analyzer via
an Ethernet LAN forremote operation,
or directly forpoint-to-point operation.
The logic analyzer connects to the
HP 16505A through a SCSI connector.
The configuration switches
Usethe switches to configure
communication to the HP 16505A. There
is a guide to these switches on the
bottom of the HP E3491A Pentium Probe.
The status LEDs
LEDs show the statusof the power
supply, the target system, and the
connection to the HP 16505A.
Additonal equipmentrequired
