1-20 N67xx DUT Power Supply Installation
Digital Control Port
An 8-pin connector and a quick-disconnect connector plug are provided 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.
The following chart describes the possible pin configuration for the digital port
functions.
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.
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.
