4/03/2003


Introduction

The Model 6514 requires firmware revision A11 to work properly
with the KE6485 IVI/VISA Instrument Driver and ExceLINX (ELNX-852C02).
If your instrument's firmware revision is lower than A11,
a firmware upgrade is required. This upgrade can also be used 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 6514

The firmware revision is briefly displayed during the power-on
sequence of the instrument. When the instrument's power is
turned on, all display annunciators will be illuminated for a
short period. Then
the firmware revision is displayed briefly as follows:

6514 REV: yyy

where:
yyy is the firmware revision (e.g. A10) of your
Model 6514.


To determine the firmware revision with remote control, use
the *IDN? query command. After sending the *IDN? command and
addressing the instrument to talk, the following response is
sent to the computer:

KEITHLEY INSTRUMENTS INC., MODEL 6514, xxxxxxx, yyy/zzz

Where: xxxxxxx is the serial number, yyy is the firmware
revision, and zzz is the display firmware revision.

Step 2. Determine next action

Based on the firmware revision of your Model 6514, choose the
appropriate course of action:

If the firmware revision is A11 or higher, an upgrade
is not required to use the KE6485 IVI/VISA Instrument
Driver and ExceLINX (ELNX-852C02) with your
instrument.

If the firmware revision is A10, an upgrade is
required. Proceed to step 3 to perform the upgrade.


Step 3. Upgrade firmware

To perform the firmware upgrade, a personal computer connected
to your 6487 is required. The PC must be at least Pentium
class running Windows 98 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 6514 mainframe.

RS-232 interface - If using the RS-232 port, use an RS-232C
cable to connect the communications port to the Model 6514.
When using RS-232 interface, the RS-232 cable must be a
straight-through cable, not a null modem cable.

Perform the following steps:

Download the 6514 A11 Firmware upgrade.exe file from
the Keithley Web site, www.keithley.com to a temporary
directory on your PC.

From Windows, click Start>>Run>>Browse.
