Each instrument serviced by the gPIb has its own Primary Address code, which enables the
computer to obtain readings from the instrument. The factory default setting on the 6200 is 15.
Some PC interfaces can access from one to fifteen 4-bit primary addresses. other interfaces can
access as many as thirty-one 5-bit primary addresses. The 6200 uses the 4-bit format.

CheCking the 6200-to-pC ConneCtion
Note:
Make sure that the 6200 and its host computer are communicating
before acquiring data.
1. Make sure the primary address is set correctly for the 6200.
2. Set the input variable to 15 characters (13 variable characters and the two required data
termination characters CR and LF. (See “Programming” in this chapter.)
3. Issue output data command “OD” and read 15 characters according to the instructions for
your gPIb interface.
