SpitFire® III
Security Key

When purchasing SpitFire® III system software, you will receive a SpitFire® III
Security Key (also called a "dongle").
The SpitFire® III system software will not run without the Security Key.

If you have purchased a turnkey system with computer included, the Security Key will arrive with the system, but will be wrapped separately to avoid damage during shipment. You will need to plug the Security Key into the computer's printer (parallel) port. If you need assistance, click here.

If you purchased SpitFire® III software only, or SpitFire® III software and board(s), you will need to attach the Security Key to your computer's printer port before installing the software.

If you have a printer plugged into the parallel port, take out the printer cable, insert the Security Key and then plug the printer cable into the Security Key. This should not interfere with your printer.

If you load the software onto another computer, you will have to put the Security Key in the parallel port of that computer before loading the software, and during operation.

The Security Key will be specific for the number of boards and the number of lines you have on one SpitFire® III system. If you change boards or upgrade the software, the Security Key will have to be returned to us to be re-programmed. The re-programming charge is $25.00 plus shipping.

If the Security Key is lost or stolen, the replacement price is the full price of the software license.
