7v firmware technical update FAQ
Note: For more recent firmware versions, see: 9v FAQ | 8v FAQ
Which instruments are affected by this change?
Most Alicat instruments manufactured on or after May 24, 2017, will ship with 7v firmware. The exception is no-change customers who have not yet approved this update.
Can I update my existing instruments to 7v?
Alicat’s 7v firmware update is compatible with most Alicat instruments that have serial numbers of 135,000 or higher. Some instruments with serial numbers between 80,000 and 135,000 may also be compatible with 7v.
Upon request, we can update your firmware to 7v during your instrument’s next annual recalibration at no charge. Alternatively, we can update instruments outside of the recalibration process for a firmware update bench fee of $80 (USD).
Will my new 7v Alicat communicate the same as my existing 6v Alicats?
Yes. Communication protocols and commands have not changed in the move from 6v to 7v, so your command set will remain the same, no matter which protocol you have been using.
Which changes will I notice?
