This file contains additional information regarding the installation
and use of the ROM upgrade software for the Model 2700 Multimeter/
Data Acquisition System. Please review the contents of this file
before installing or using the ROM Upgrade software.

Introduction

Upgrade Software for the Model 2700 is available for those who wish
to have the latest firmware enhancements and upgrades installed on
their instrument.

Step 1. Determine the firmware revision of your Model 2700

The firmware revision is briefly displayed during the power-on
sequence of the instrument.  When the instrument is turned on, all
display annunciators will turn on for a short period of time. After
that, the firmware revision will be briefly displayed as follows:
    REV: yyy zzz
    where:
        yyy is the mainframe revision (e.g., B04 of the Model 2700).
        zzz is the display board firmware revision (e.g., A01),
        which does not apply to this upgrade.

To determine the firmware revision remotely, use the *IDN? query
command.  After sending the *IDN? command and addressing the
instrument to talk, the following response message is sent to the
computer:
    KEITHLEY INSTRUMENTS INC.,MODEL wwww,xxxxxxx,yyy/zzz
    where:
        wwww is the mainframe model (2700).
        xxxxxxx is the serial number of the mainframe.
        yyy is the firmware revision of the mainframe.
        zzz is the display board firmware revision.

Step 2.  Determine the next course of action

Based on the firmware revision of your Model 2700, choose the
appropriate course of action:

    a)  If the firmware revision is B06 or higher on the Model 2700,
        an upgrade is not needed.
 
    b)  If the firmware revision is B05 or lower on the Model 2700,
        and you wish to have the latest firmware enhancements and
        upgrades installed on your instrument, proceed to Step 3
        to perform the upgrade.

    NOTE:  If the firmware revision begins with the letter A (e.g.,
    A01, A02, etc.) for the Model 2700, DO NOT perform the upgrade.
    For these revisions, a hardware upgrade is also required.
    Contact your local Keithley service center for instructions and
    pricing for upgrading your Model 2700.

Step 3. Perform the ROM upgrade

System requirements
The minimum requirements include a Pentium-class PC running Windows
95 or later. The firmware can be installed via the IEEE-488 bus or 
the RS-232 interface:
    IEEE-488 Bus - If using the IEEE488 bus, a Keithley, CEC, or
    National Instruments IEEE-488.2 interface board must be
    installed in the PC.  Use an IEEE488.2 cable to connect the
    interface board to the Model 2700 mainframe.

    RS-232 interface - If using the RS-232 port, use an RS-232C
    cable to connect the communications port to the Model 2700.
    NOTE: With RS-232, upgrade takes approximately 20 minutes.

ROM upgrade procedure
    1.  From Windows, click Start->Settings->Control Panel>Add/
        Remove Programs, and then remove any Model 2700 ROM
        upgrades if previously installed.  NOTE: All saved
        scanlists, setups, and buffer readings will be lost with
        this upgrade.
    2.  Download the 2700 B06 Firmware upgrade.exe file from the
        Keithley Web site, www.keithley.com to a temporary directory
        on your PC.
    3.  From Windows click Start->Run.  Click the Browse button and
        navigate to temporary directory and select the 2700 B06
        Firmware upgrade.exe file.  This should return you to the
        Run dialog box.  Click OK to run the WinZip Self-Extractor.
        Specify a temporary directory to unzip the install files to
        and click Unzip.  When the unzip operation has finished
        click OK and then Close.
    4.  From Windows click Start->Run. Click the Browse button and
        navigate to the temporary directory where you unzipped the
        files and select the setup.exe file.  This should return
        you to the Run dialog box.  Click OK to run the setup and
        follow all prompted instructions.
    5.  From Windows click Start->Programs->Keithley Instruments->
        Model 2700 Flash Upgrade vB06 and follow all prompted
        instructions.
    6.  Perform Step 1 above (determine the firmware revision of
        your mainframe) to verify correct installation.  NOTE:
        Error +516,"Battery Backed Memory Lost" will be displayed
        after the first power cycle after upgrade.
