NOTE: These cables have been replaced by the Parallel Cable IV (Model ID = DLC7).

The XChecker cable is used to download to an FPGA, verify the FPGA configuration, and probe FPGA internal signals. You may use the Windows-based Hardware Debugger software or the DOS-based XChecker software to communicate with the cable. Your cable is an XChecker cable if the Model ID on the pod is "DLC4."

The Parallel Download cable is used to download to an FPGA. You may use the Windows-based Hardware Debugger or JTAG Programmer software or the DOS-based XChecker software to communicate with the cable. Your cable is a Parallel Download cable if the ID number on the pod is "ML5."

The Parallel Cable III (also known as the EZTAG cable) is used to download to a 9500 CPLD. You may use the Windows-based EZTAG software or the JTAG Programmer that comes with M1 to communicate with the cable. The Parallel Cable III can also be used to program FPGAs when using Hardware Debugger (version 1.4.12 or later), JTAG Programmer, or iMPACT software. The Model ID number on pod of a Parallel Cable III is "DLC5."
