Appendix B

Using the Digital Port

	Digital Control Port	90
	Configuring the Digital Control Port	91
	A Digital Control Port consisting of seven I/O pins is provided to
	access various control functions. Each pin is user-configurable. The
	following control functions are available for the I/O pins:
	Bi-directional Digital I/O
	Digital Input only
	External Trigger
	Fault Output
	Inhibit Input
	Output State (see Appendix D)
	Earlier Agilent N6700A mainframes use a 4-pin connector instead of the 8-pin
NOTE
	connector available on the N6700B, N6701A, and N6702A mainframes. Refer to

the Service Guide for information on pin functionality of the 4-pin connector.
