Pull Ups - SeaLevel PIO-32.PC User Manual

Pull Ups

Ten pin bussed resistor packs are installed to provide pull-ups to the input
ports. These are installed on all ports. The pull-up resistor packs are rated at
10K ohms. Figure 2 below provides the bussed resistor and corresponding port.
The resistors insure that no line is floating which is not connected. This
provides consistent biasing on all un-terminated lines.
