The cost-effective pricing on the USB-100 and ScanWorks’ unique network license lowers the cost-of-ownership for boundary-scan test and in-system programming to an all-time low without sacrificing the powerful tools, ease-of-use and sophisticated capabilities of ScanWorks.
ScanWorks supports the USB-100 in the same way as it supports the PCI-100, PXI-100, and PCI-400 controllers, simplifying the migration of boundary-scan projects from one ScanWorks station to another. In the ScanWorks “Select Hardware” dialog box, the user simply selects the USB-100 as the controller type. The boundary-scan test clock (TCK) frequency and voltage settings for the test access port (TAP) signals and discrete IO (DIO) signals are set separately in the “Configure Hardware” dialog.
The value pricing on the USB-100 can make the entire organization much more efficient. For example, ScanWorks could be installed and authorized by network licenses in multiple locations and USB-100s could be moved among the ScanWorks installations as needed. The mobility of the USB-100 means that ScanWorks could be easily deployed where it is needed and when it is needed throughout the organization. Even with occasional ScanWorks users, the USB-100 can improve efficiencies. Ten users might need access to ScanWorks intermittently. The pricing on the USB-100 does not preclude each of these 10 users being issued a USB-100 controller. They could then share two or three network licenses of ScanWorks.
The USB-100 hardware kit includes a controller pod, a standard two-meter USB mini-B cable, a 20-pin cable to connect the USB-100 controller to a UUT and an adapter to interface the USB-100’s 20-pin connector to the standard ScanWorks 14-pin boundary scan connector. The USB-100’s 20-pin connector conforms to the same pin-out as the PCI-400 TAP port pin-out.
The USB-100 supports all primary boundary-scan test and programming functions, including TAP state transitions for multi-drop device communication protocols. The USB-100 supports one set of JTAG TAP signals and four bidirectional discrete IO (non-boundary-scan) signals. It supports UUT logic levels ranging from 0.8V to 3.3V (5V tolerant) and its test clock (TCK) frequency range extends from 20 MHz to 80 KHz. Although a high TCK frequency is supported, the throughput is limited by the USB protocol to approximately three megabits-per-second (Mbps). The throughput of the USB-100 is adequate for all but the most time-critical boundary-scan applications.
