Figure 2. Switch Positions

In Figure 2, DIP switch sections 6, 7, and 8 allow the computer to read Out A, Out B or Lock Detect from

the PLL device. Each of the inputs can only be read on one board at a time. But each item could be read

on a different board. In a three–board cascade, Out A could be read from the first board, Out B from the

second, and Lock Detect from the third. There is no way to determine in software the board address of a

particular input. The control program doesn’t make use of these inputs. Pin assignment on the printer

port connector is:
