Note
Certain cameras may offer, depending on their settings in
combination with the use of FirePackage higher packet sizes.
Consult your local dealer's support team, if you require
additional information on this feature.
Note
How to extend the size of an isochronous packet up to 11.000
byte at S800:
•
See register 0xF1000048, ADV_INQ_3, Max IsoSize [1] in

Caution
As mentioned earlier, it is very important not to exceed an
inrush energy of 18 mWs in 3 ms. (This means that a device,
when powered via 12 V bus power, must never draw more
than 1.5 A, especially in the first 3 ms.)
Higher inrush current may damage the physical interface (PHY)
chip of the camera and/or the PHY chip in your PC.
For a single Guppy PRO camera inrush current may not be a
problem. But daisy chaining multiple cameras or supplying bus
power via (optional) Hirose power out to circuitry with
unknown inrush currents needs careful design considerations.
