ScanBox boundary scan (JTAG) controller

ScanBox is the next generation Boundary Scan (JTAG) test platform. Based on Acculogic’s high performance JPCI 32-bit TAP controller chip with patented Adaptive Clocking Technology. ScanBox’s built-in Ethernet and USB2 provides the flexibility and performance required for Remote Distributed Testing (RDT). ScanBox combines built-in Boundary Scan controller and PC-standard connectivity with the modularity and size reduction of card cage-based systems. ScanBox’s compact, flexible package, high-speed data rates and reliable operation meet the needs of R&D and manufacturing and test engineers delivering electronics for the aerospace/defense, automotive, industrial, and medical and consumer electronics markets.

Remote access and distributed testing
Remote control and distributed testing is essential for Boundary Scan (JTAG) applications such as design validation, environmental tests, automated factory test, repair and calibration. ScanBox is based on industry standard Ethernet technology which has a wide general acceptance. Advantages of using Ethernet include TCP/IP error checking, fault detection and long inter-device connectivity. Ease of cable routing and inexpensive networking hardware. Ethernet enables the ScanBox to be deployed in a local, intranet or internet based distributed environment.


ScanBox™ operating environments
ScanNavigator™ RTE features a comprehensive graphical user environment for ScanMaster setup and runtime control. Through the ScanNavigator RTE, ScanMaster executes boundary scan test and on-board programming routines and can easily be set up to perform conditional looping and branching operations – a critical feature for program debug and execution of diagnostic routines. ScanMaster can also be controlled through DLL calls using test executives such as National Instruments’ TestStand and Teradyne’s TestStudio, or through direct API access with language-based programming.
