HES Fixtures - uploading firmware

I'm new round 'ere...
I need to update the firmware in some SS 575 fixtures.
I see references to widgets, upload dongles, parallel port dongle, etc.
How can I do this without dropping big bucks?

Sorry for the late response. The latest version is 13.0.10. If one of your units has this version, you can cross load from that fixture, to all your other fixtures. The only other way to upload the software is to use a dongle with echo or winupdate, which is on our site.
