Installing the software in the HP 16505A
Prototype Analyzer
To install the HP E3491A software (Run Control Tool) in the
HP 16505A Prototype Analyzer:
•Power up the prototype analyzer.
•Insert the HP E3491A floppy disk in the floppy disk drive.
•In the Session Manager menu, select Update. The prototype
analyzer will read the directory of the floppy disk.
•When the menu changes to show the file group "E3491A", select
Update/Install. The menu will query "Install the file group
E3491A?" Select OK. When the installation is complete, the menu
will display ""Filegroup E3491A successfully installed." Select OK.
•Close the HP 16505A Update/Install window.
•To verify installation, start a session in the HP 16505A. Look for
the µp Control Tool in the Toolbar. If the µp Control Tool is in the
Toolbar, the installation is complete.

Connecting the HP E3491A Pentium Probe to a
Power Source
The HP E3491A Pentium Probe does not have an On/Off switch. To
turn the HP E3491A Pentium Probe on or off, plug or unplug it from
the power supply.
To choose a power cord
The HP E3491A Pentium Probe is shipped from the factory with a power
supply and cord appropriate for your country. If the cord you received is not
appropriate for your electrical power outlet type, contact your
Hewlett-Packard sales and service office.
Warning Use only the supplied HP power supply and cord.
Failure to use the proper power supply could result in electric shock.
Caution Use only the supplied HP power supply and cord.
Failure to use the proper power supply could result in equipment damage.

To connect the power cord and turn on the
HP E3491A Pentium Probe
1 Connectthe power cord to the power supply and to a socket outlet.
2 Connectthe 5V power cord to the back of the HP Pentium Probe.
The power lighton the target side ofthe HP Pentium Probewill be illuminated. The HP Pentium Probe does not have an
On/Off switch.

Connecting the Probe to the Prototype Analyzer
The Pentium probe can be connected directly to the prototype
analyzer for a point-to-point connection, or it can be connected via a
LAN. The LAN connection allows remote operation; it also allows a
probe to be shared by more than one prototype analyzer.
The following sections describe the connections for point-to-point and
LAN configurations.
8

Connecting for a point-to-point configuration
The point-to-point connection is technically a LAN connection, with only two
nodes.
•Use the supplied 10Base-T cable (HP part number 5061-7342) to connect
the Pentium probe directly to the prototype analyzer (see figure 3).
•The configuration switches must be set for a LAN configuration. Switch 1
must be set to OPEN, indicating that a LAN connection is being made.
Since this is a 10BASE-T connection, switch 5 must also be set to OPEN
(see figure 5).
•Use the procedure in "Setting Up LAN Communication" to set the Ethernet
address, IP address, and gateway address.

Connecting to a LAN
The HP E3491A Pentium Probe has two LAN connectors
(see figure 4):
•A BNC connector that can be directly connected to an IEEE 802.3
Type 10BASE2 cable (ThinLAN). When using this connector, the
HP E3491A Pentium Probe provides the functional equivalent of a
Medium Attachment Unit (MAU) for ThinLAN.
•An IEEE 802.3 Type 10BASE-T (StarLAN) connector.
Caution Use either the 10BASE2 or the 10BASE-T connector. Do not use both. The
HP E3491A Pentium Probe will not work with both connected at the same
time.
The configuration switches must be set for a LAN configuration. Switch 1
must be set to OPEN, indicating that a LAN connection is being made. For
10BASE-T connections, switch 5 must also be set to OPEN (see figure 5).
Refer to "To set the 10BASE-T configuration switches" for additional
information on configuring 10BASE-T switches.
Use the procedure in "Setting Up LAN Communication" to set the
Ethernet address, IP address, and gateway address.

To set the 10BASE-T configuration switches
Set switches S7 and S8 to CLOSED unless one of the following conditions is
true:
•If the LAN cable exceeds the standard length, set switch S7 to OPEN.
The HP E3491A Pentium Probe has a switch-selectable, twisted-pair receiver
threshold. With switch S7 set to OPEN, the twisted-pair receiver threshold is
lowered by 4.5 dB. This should allow you to use cable lengths of up to about
200 meters. If you use a long cable, you should consult with your LAN
cabling installer to ensure that:
•The device at the other end of the cable has long cable capability, and
•The cable is high-grade, low-crosstalk cable with crosstalk attenuation
of greater than 27.5 dB.
When switch S7 is set to CLOSED, the LAN port operates at standard
10BASE-T levels. A maximum of 100 meters of UTP cable can be used.
•If your network doesn’t support Link Beat integrity checking or if the
HP E3491A Pentium Probe is connected to a non 10BASE-T network
(such as StarLAN) set this switch to LINK BEAT OFF (0 or OPEN).
In normal mode (switch S8 set to CLOSED), a link integrity pulse is
transmitted every 15 milliseconds in the absence of transmitted data. It
expects to receive a similar pulse from the remote MAU. This is the standard
link integrity test for 10BASE-T networks. If your network doesn’t support
the Link Beat integrity checking or if the Pentium Probe is used on a non
10BASE-T network (such as StarLAN) set this switch to LINK BEAT OFF
(OPEN).
Note Setting switch S8 to OPEN when Link Beat integrity checking is required by
your network will cause the remote MAU to disable communications.
