    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.

  • Page 15: To Connect The Power Cord And Turn On The Hp E3491A Pentium Probe

    1 Connect the power cord to the power supply and to a socket outlet. 2 Connect the 5V power cord to the back of the HP Pentium Probe. The power light on the target side of the HP Pentium Probe will be illuminated. The HP Pentium Probe does not have an On/Off switch.

  • Page 16: Connecting The Probe To The Prototype Analyzer

    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.

  • Page 17: 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.

  • Page 18: Connecting To A Lan

    C a u t i o n 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.

  • Page 20: To Set The 10Base-T Configuration Switches

    • 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.

    HP E3491A Pentium Probe. These addresses must be initialized for either point-to-point or LAN connections. The Pentium probe must be on the same subnet as the HP 16505A Prototype Analyzer. The HP E3491A Pentium Probe automatically sets the subnet mask based on the subnet mask used by other devices on the network.

  • Page 23: Setting Up A Serial Connection

    To set up a serial connection, you will need to: • Set the serial configuration switches • Connect the HP E3491A Pentium Probe to the RS-232 interface • Connect a serial cable between the host computer and the HP E3491A Pentium Probe •...

  • Page 24: To Set The Serial Configuration Switches

    Use a grounded, shielded cable. If the cable is not shielded, or if the cable is C A U T I O N not grounded at the serial controller, the HP E3491A Pentium Probe may be damaged by electrostatic discharge.

  • Page 25: To Verify Serial Communications

    Plug the power cord into the HP E3491A Pentium Probe. When the HP E3491A Pentium Probe powers up, it sends a message (similar to the one that follows) to the serial port and then displays a prompt: Copyright (c) Hewlett-Packard Co.

    Pentium Preprocessor If the target system does not have either the 20- or 30-pin Intel-defined debug port, the HP E3491 Pentium Probe can be connected to the target system through the HP E2457A Pentium Preprocessor Interface. The 64762-61602 cable assembly is used to connect the DBRESET signal from the HP E3491A Pentium Probe because DBRESET is not a Pentium processor pin.

It’s also possible for there to be a problem with the HP E3491A Pentium Probe firmware while the LAN interface is still up and running. In this case, you must reboot the HP E3491A Pentium Probe by disconnecting power to the HP E3491A Pentium Probe and reconnecting it again.

  • Page 52: If You Have Lan Connection Problems

    (Remember: if you change any switch settings, the changes do not take effect until you cycle power.) If the HP E3491A Pentium Probe still does not respond, you need to verify the IP address and gateway mask of the HP E3491A Pentium Probe.
