“Do you want to update? [Y/N]”

Press “Y” to accept update.

You will see message warning again.

“Doing this will erase the program memory [Y/N]”

Press “Y” again to accept update.

NOTE: Pressing “Yes” again will permanently erase the entire program memory and the VSI-Pro Max will not function

until firmware is loaded. Make sure you have the proper firmware file ready or the VSI-Pro Max will be rendered useless.

Finish erasing the program memory step.

Next, you have to send file to update firmware by click on “Transfer Menu” and select “Send Text File” and wait until

finished programming. Progress dots will be displayed on the terminal program until finished and takes approximately 2.5

minutes.

NOTE: If for some reason you are disconnected from the VSI-Pro during downloading, power is lost to the VSI-Pro Max

or PC or the firmware update does not finish for any reason you can repeat the procedure above again. The bootstrap

loader never is erased and will always request for a valid firmware update until achieved.

To do this just power up the VSI-Pro Max or press reset while the terminal program is connected and you will see the

prompt messages as above window.

Second, you go to the menu of the VSI-Pro Max “Download/Upload Setup” then select ==> “Update Firmware” and

then press Set. Now you will see message in Hyper Terminal.

NOTE: If you have errors or can not update firmware make sure the “Scroll Lock” is not on when you use Hyperterminal

or if using Vista OS with Hyperterminal there is a Microsoft compatibility with this program and will be very slow about

x20 times slower so you must wait until the firmware is finished no matter how long it takes and can not cancel or

disconnect for will cause errors or even cause the firmware function to not update at all and disable the VSI-Pro Max.
