Project Introduction: Mobile phones have quickly become a necessary tool in our modern-day lives, and they are evolving so quickly that many new technologies are becoming standard features. Not only do these mobile devices allow access to communications anywhere, but also access to information and advanced technology, such as digital cameras, digital video/voice recorder, calendars, email, MP3 players, GPS navigation, and more). The latest technology to be incorporated in these devices is HSDPA-enabled (High-Speed Downlink Packet Access) USB ports, which allows higher data transfer speeds and capacity.

System Requirements: One of the electronic manufacturers would like to leverage industrial grade USB hub to test the latest new USB interface HSDPA, to meet mass product with high performance yet low cost.

They were looking for products that:

• Provide full-speed and high-speed data transmission rates
• Provide lockable external power connector for hubs' power
• Provide firm mount kit
• Provide firm cable connection

Project Implementation:

USB-4622: 5-port USB 2.0 Hub

USB-4671: GPIB USB Module

System Description: USB-4622 was used to connect with four HSDPA modules, and USB-4671 was used to connect the instrument. When the testing program which inside the box PC issues the command to each HSDPA through USB-4622, the instrument will get the response signals and verify them to see if match the condition or not. After that, the display will show the pass or fail information to the operator.

Conclusion: After choosing Advantech products, the customer was able to significantly increase productivity, while saving on cabling and installation efforts. The manufacturer also saved 29% on the test station's cost, mainly due to the ease of installation and connectivity options. Furthermore, the test system is very reliable with no downtime since installation over 1 year ago.

Advantech's USB DAQ product series were designed for industry applications. Two unique features are dual end lockable cable and versatile mounting method. With Advantech's unique features, user can easy mount the module into the suitable place and trust the connection in the field.

The USB-4671 is a high-performance USB module with a GPIB interface, which can perform basic the IEEE-488 talker, listener and controller function required by IEEE 488.2. User can also connect up to 15 piece GPIB instruments. Therefore, USB-4671 is especially suitable for instruments and control.

The USB-4622 is a real USB 2.0 hub, which provides high-speed and full-speed data transmission rates. With its lockable USB cable and external power cable, it's very reliable to utilize in the product line.
