Part 2 Getting Started
To begin using the Excimer evaluation board,
1. Connect one end of the serial null modem cable to the boardÕs serial port 1 and the other end to
COM1 on the PC.
2. Launch a terminal emulator program such as Smartcom or HyperTerminal on the PC. ConÞgure for:
Ñ 9600 baud
Ñ 8 data bits
Ñ no parity
Ñ 1 stop bit
Ñ hardware ßow control (RTS/CTS)
Ñ VT100 emulation
3. Connect the parallel cable between the parallel port on the PC and the Wiggler interface board.
4. Connect the twenty pin ribbon cable on the Wiggler to the JTAG/COP header on Excimer.
CAUTION: Get the orientation correct! Pin 1 on the cable has a red stripe; Pin 1 on the JTAG connector is
labeled. While the connector is designed to be keyed, the cables rarely are.
NOTE: The JTAG connectorÕs pin 1 will be rotated 180 degrees from revision X2 to revision X3 to better
