Inverted Data and Control Signals
Position JP1 and JP2 horizontally on the jumper posts to select
inverted data and control signals. Figure 5 shows the position of the
jumpers on the pc board. Table 4 shows the relative signal levels.
Inverted Data and Non-Inverted Control Signals
Position JP1 horizontally top jumper posts and remove JP2 to
select inverted data and non-inverted control signals. Figure 6 shows
the position of the jumpers on the pc board. Table 5 shows the relative
signal levels.
