All pins do not have to be configured in the same way. Some can be used as isolated outputs while others
are single-ended I/O. Functions can also be mixed, with some pins being general purpose Digital I/O
while others have a specific purpose. Chapter 2 under “Digital Connections” provides further information
about the purpose and application of the digital I/O signals. Any pin can be configured for selections 1
through 7. The common ground pin is the return for these selections.
Selections 10 and 11 are the power fail signals. One is the input, to signal that a power failure has
occurred; the other is the output, to indicate when the shutdown state has been saved. Pin 13 is a special
purpose signal discussed under cfSetDigitalConfig in chapter 5.
Selections 8, 9, 12, and 14 are the isolated output selections, which require a dedicated pair. Dedicated
pairs are located on adjacent pins (0-1, 2-3, 4-5, etc.), up to a maximum of eight pairs. For example to use
the pair pin 0-1 as an isolated output, configure pin 0 to be the isolated output and do not configure pin 1.
Pin 1 is the minus connector of the output. Writing to or reading pin 1 has no effect. Isolated outputs
cannot be used as inputs.
After you press Enter, select whether the pin will be configured as either High True or Low True.
