FAQ page for the CFM Disconnect board

 

Q: Which instruments or other 3rd party devices are supported by this CFM?

A: This CFM was designed for some JTAG tools, it has the following pin compatible connectors available:

- 14pin Xilinx 2mm header (dual row)

- 9pin Xilinx header (single row)

- 10pin Altera Byte blaster header

The newer Rev-B also includes a 20pin JTAG interface for up to 2 units.

Although the pinout is fixed, practically any instrument can be connected, provided a fitting adapter cable is made.

 

Q: Are all headers installed?

A: No, the standard version of this CFM comes with two of the 20 pin JTAG interface headers installed. This is the most flexible use of the signals And also is the most popular. It was the reason for the newer revision, and we kept the original headers in the design so users have the option to install headers for the respective interface if they choose to do so.

Q: Are the direct signals wired directly from the JTAG connector to the interface or is there a way to disconnect the signals?

A: This CFM has relays, which disconnect (NO) the 4 direct signals, those signals can be switched (thru another relay) to be connected to the MUXed signals.
