An interface module for up to 4 USB3.0 cameras.

---

Description

This module can be used in applications where USB3.0 is required and some input/output interfacing is necessary. The module has 4 USB3.0 standard-A ports and has an internal USB3.0 hub controller on the module which support following speed modes:

• Super Speed (SS) - 5 Gbps
• High Speed (HS) - 480 Mbps
• Full Speed (FS) - 12 Mbps
• Low Speed (LS) - 1.5 Mbps

This allows you to stream up to 4 cameras in high resolution and a high frame rate. All ports are backwards compatible with USB2.0.

The module has also 4 Digital Outputs (DO) and 4 Digital Inputs (DI). Both are 24VDC compatible and are optical isolated from the BLOX device. Those I/O can used to interface with a remote system such as a PLC system.

Block diagram

The above diagram shows the block diagram of the interface module. There are 3 main parts:

• USB3.0 Hub
• Digital Output circuits
• Digital Input circuits

The USB3.0 Hub is connected to the BLOX USB3.0 port. This way, the BLOX USB3.0 port is extended with 4 USB3.0 ports P1…P4.

The digital outputs and inputs are galvanic isolated from the BLOX. This allows you to use 2 different power supplies: one for the BLOX (24VDC) and the other for the I/O (24VDC I/O).

Connections
