The new member to the Scanflex module series from Goepel Electronic provides five ports for the universal test of industrial interfaces, which can be completely electrically isolated with relays. With the SFX-9305/R, users are now able to combine functional test procedures for bus interfaces such as LAN, USB, CAN or LIN with vector-less working test methods on a unique platform. In addition to increased fault coverage, the new integration opportunities result in reduced test costs by saving separate process steps.

The SFX-9305/R module provides five independent, freely configurable bus ports. The target is physically accessed by a selection of bus access cables (BAC). The current configuration is automatically identified, whereby BAC type and quantity are freely definable. By parallel operation of several SFX-9305/R modules, the number of available bus ports is nearly unlimited. Supported interfaces are LAN (10/100/1000), USB 2.0 (Host/Slave), Bluetooth, CAN (high-speed/low-speed), LIN, RS-232 and RS-422/458. Additional interfaces are being developed. The available interface functions contain the step-wise handling of protocol layers including bi-directional data transfer. Hence, users can completely control the bus target without additional driver software and clearly identify faults.

SFX-9305 can be combined with all Scanflex controllers on the basis of PCI, PCI Express, PXI, PXI Express, FireWire, USB and LAN. It is fully supported in the industrially leading JTAG/Boundary Scan software System Cascon from version 4.5.x on. Module programming and handling of test program data are based on user-friendly Caslan instructions. Caslan is currently the most powerful Boundary Scan programming language with several hundred commands supporting IEEE1149.1, IEEE1149.4, IEEE1149.6, IEEE1532 and JESD71 as well as mixed signal operations and VarioTAP for emulation test as well as control of chip embedded instruments.
