ASSET's new Ethernet controller for ScanWorks tests four circuit boards at once

The RIC-4000 controller for ScanWorks features four Test Access Ports (TAPs) that conform to the IEEE 1149.1 (JTAG) boundary scan test standard. The RIC-4000's TAPs connect the UUTs to the PC-based ScanWorks which applies test routines without physically probing the boards. ScanWorks is often deployed throughout a product's life cycle, beginning in design for board bring-up, subsequently in manufacturing and assembly for test purposes, and lastly in field service to perform troubleshooting.

Because ScanWorks is software, it does not require placing a physical probe on a UUT. This means that it avoids many of the problems that probe-based testers like in-circuit test (ICT) systems are running into, said Kent Zetterberg, ASSET's boundary scan product manager. The RIC-4000 four-TAP controller is small and very portable, and each one has its own IP address. So, the controller might be in one location where it is connected to multiple UUTs, while ScanWorks and the test engineer are across the globe testing and debugging the UUTs over the Internet. This gives the manufacturer a great deal of flexibility. It can target its test and human resources anywhere in the world.
