VMUPG Option Upgrades

Installation Instructions

Upgrade Your

Measurement Set

Once you have installed the firmware-upgrade software on your PC, you can upgrade multiple VM700T or Turbo VM700A measurement sets without having to reload the floppy disks. To upgrade the firmware of a VM700T or Turbo VM700A measurement set from your PC, perform the following procedure:

CAUTION. To avoid loading incorrect firmware into your measurement set, be sure to use the correct firmware-image archive number for the instrument firmware you want to install. If you have installed multiple firmware images, you will have more than one firmware-image directory. If you load the wrong firmware, repeat the firmware upgrade using the correct firmware version.

The firmware-upgrade installation program creates a directory under the VM_UPGRD directory using the current firmware-image archive number loaded on the floppy disk set. The firmware-image number is based on a date using a format of year, month, and day. In most situations, you will want to load the latest version of the firmware into your measurement set.

NOTE. Do not perform this upgrade if your firmware image number is 030930 or higher.

1. If your firmware image number is lower than 030930, change the working

directory on your PC to the following firmware-image directory:

<destination drive>\VM_UPGRD\F_<archive number>

For example, if you load the firmware-upgrade software to a destination

drive of C:\ and your firmware archive number is 000815, then your

command-line directory should look like the following:

C:\VM_UPGRD\F_000815

2. Connect the LapLink cable between the PC and the measurement set.

NOTE. To perform the firmware upgrade on multiple measurement sets, you will need to run the BURN.BAT program on each individual instrument.

3. Windows 3.1 or MS/DOS only. To perform the firmware upgrade,

run BURN.BAT and follow the prompts.

4. Windows 95/98 only. To perform the firmware upgrade, run BURN.BAT

from Windows Explorer and follow the prompts.

After Installing the Firmware. After installing the firmware upgrades go to Install the New Option Key refer to page 47.
