Note:
Check the manual provided with your software for full instructions.
1. Use the following information to answer the formatting questions asked when installing
your gPIb software.
• All GPIB data acquisition systems requires the use of data termination characters. The
6200 uses the gPIb standard termination characters “Carriage Return (CR)-Line Feed
(LF).” Provide them in that order.

2. Set the timeout for at least one second, if you are asked to set a communication fault delay
timeout.
• If the communication fault delay timeout is too short, or if the computer resets the
interface too quickly, the host instrument may stop responding.
