Appendix B Digital Port Functions
96 Series E4360 User’s Guide
Digital Control Port
An 8-pin connector and a quick-disconnect connector plug are provided
on each instrument for accessing the digital control port functions.
The digital control connector accepts wires sizes from AWG 14 to AWG
30. Note that wire sizes smaller than AWG 24 are not recommended.
Disconnect the connector plug to make your wire connections.
NOTE
It is good engineering practice to twist and shield all signal wires to and
from the digital connectors. If shielded wire is used, connect only one
end of the shield to chassis ground to prevent ground loops.
The following chart describes the possible pin configuration for the
available pin functions. For a complete description of the electrical
characteristics of the digital I/O port, refer to Appendix A.
Pin Function Available configurable pins
Digital I/O and Digital In
External Trigger In/Out
Pins 3 through 7
Output Couple State
Fault Out
Inhibit In
Common (⊥)
Pin 8
In addition to the configurable pin functions, the active signal polarity for
each pin is also configurable. When Positive polarity is selected, a logical
true signal is a voltage high at the pin. When negative polarity is
selected, a logical true signal is a voltage low at the pin.
For a complete description of the electrical characteristics of the digital
I/O port, see Appendix A.
