USB uEye LE pin assignment I/O connector

Hinweis

The following specifications apply to the board-level versions of the USB uEye LE. The inputs/outputs mentioned are not accessible in the housing versions.

10 pin connector (PCB version only)

Pin	Description	Fig. 378: USB uEye LE PCB version - I/O connector
1	USB power supply (VCC) 5 V
2	USB ground (GND)
3	Digital input without optocoupler (+)
4	Digital output without optocoupler (+)
5	Power supply of the internal voltage transformer 3.3 V or 3.0 V*1
6	USB ground (GND)
7	Programmable input/output (General Purpose I/O) 1
8	Programmable input/output (General Purpose I/O) 2
9	I2C bus clock signal
10	I2C bus data signal

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

Achtung

The pins 1 and 5 are voltage output of the camera.

Do not apply an external voltage on these outputs thus this may be destroy the camera.

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 Imaging Development Systems GmbH 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.

Max. admissible current with only one power output used
USB power supply 5 V	150 mA
Power supply of the internal voltage transformer (3.0 V or 3.3 V)*1	100 mA

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

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

	Min.	Max.
Signal level "Low"	0	0.4	V
Signal level "High"	2.4	3.0 V or 3.3 V*1	V
Output current	0	4	mA

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

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.
