The Embedded I/O Company

The JTAG Chain of the connected hardware module

which is useful to program and debug onboard devices

can be accessed in two different ways:

If it is accessed via the 14-pin Header, which must be the

case when communicating with Xilinx Devices, a "Xilinx

Platform Cable USB II" (which is required) can be

connected without any adaption.

If the JTAG Chain is accessed via the USB interface,

Channel A of the USB Controller is not used to

communicate with Interface A, but to generate JTAG

signals for debugging or programming reasons. In this

configuration, Lattice Devices for example can directly be

programmed without the necessity of an additional

Programming Cable, as the TA900 is directly supported

by Lattice's Software Tool "ispVM".

The TA900 is self-powered by the FPC Connector which

means that it is not necessary to connect the Interface

Box to USB to provide a supply voltage.

The Interface Box meets the requirements to

operate in extended temperature range from -30° to

+75°C and comes with a USB A to USB B Cable

and an FPC Flexcable.
