What is the real transfer speed?
xiC camera can deliver up to 450Mbyte/sec. This requires that certain conditions are met, see

Why can I not achieve maximum transfer speed?
In order to reliably achieve maximum transfer speed it is necessary to verify that you are using recommended hardware (please
see
, and that all software requirements are met.
) - XIMEA Control Panel free software tool, facilitates the task of verification of XIMEA
USB3 Vision camera installations.
6.1.3.4.
What voltage should be applied to Digital Input of xiC to turn it on/off?
xiC camera features two type of inputs (-UB, -TC only). First is optoisolated input only. Second is INOUT set to input function.
Following table shows different levels of Voltage on Digital Input (VDI) on xiC and their logical interpretation.
VDI (Opto-isolated)
Logical level
<2Vdc
Off (zero)
2-4Vdc
Undefined
>4Vdc

6.1.3.5.
What is the implementation of Digital Output (VDO) of xiC?
xiC cameras features two kind of digital output:
1. Opticaly isolated digital output - opto-isolated NPN open collector type, max. load current 25mA, max. open voltage 24Vdc.

2. Non isolated high impedance input/output
