JTAG Programmer GuideChapter 2: Hardware
Download Cables
There are two cables available for use with the JTAG Programmer. The first is an RS232 serial cable known as the XChecker Cable. The second is the Parallel Download Cable which can be connected to a PC's parallel printer port.
There are a few advantages to be considered in selecting a cable:
- The XChecker Cable connects to the serial port of both workstations and PCs.
- The Parallel Cable has better drive capability. The Parallel Cable can drive up to 10 XC9500/XL/XV devices in a boundary-scan chain, and the XChecker Cable can drive up to 4 XC9500/XL/XV devices.
- The Parallel Cable is at least 5 times faster.
Note: If you have a Parallel Download Cable proceed to Parallel Cable.
