PIO-48.PC104 User Manual
Pull Ups
Eight resistors are installed to provide pull-ups to the input ports. These are installed
on all ports. The pull-up resistors are rated at 10K ohms. Figure 4 below provides
the resistors and corresponding port. The resistors ensure that no line is floating
which is not connected. This provides consistent biasing on all un-terminated lines.
