*1) This voltage depends on the supply voltage required for the sensor used (see table below)

 

Hinweis

The 10 pin I/O connector of the USB uEye LE can be equipped with a 2 x 5-pin connecting plug with a 2.54 mm (0.1") lead spacing.
IDS shall not be liable for any damage to the camera or connected devices arising from installation of the connecting plug.

Achtung

If the 3.3 V and the 5 V power supplies are used simultaneously, please observe that the maximum power available from the USB bus is 2.5 W. Choose the overall current in such a way that the maximum power of 2.5 W will not be exceeded.

GPIO specifications

The two GPIOs (General Purpose I/O) can be used as inputs or outputs. This selection is made by software using the corresponding SDK API functions. Please observe the following criteria:

Input:        3.3 V LVTTL, max. 3.3 V input voltage
Output:        3.3 V LVTTL, max. 4 mA

I2C operation

Hinweis

From driver version 3.20, the I2C bus is operated with a clock frequency of approx. 300 kHz. For earlier versions, the clock frequency is 100 kHz.

 

Multi master mode is not allowed on the I2C bus while the USB uEye LE camera is used.
