7. Baud Rates and Response Times
7.1 Implementation – PANCHROI, RED & S4I Zooms; S4I Primes; 5I
Primes
Message transmission time is affected by the length of the data stream and baud rate.
Earlier S4I Prime and Zoom lenses with 10-bit ADC have slower clock speeds than the later
S4I Primes lenses with 12-bit ADC.
