Hitachi UX2 - 4.1. Basic Operation Flow

32
[SW1 to SW3 settings on the EZJ144 board]
[Cautions on using the mixture of NPN/PNP interfaces]
Input/output signals of the pin numbers 4 and 5 on the terminal block TB1 and the pin numbers 14 to 23 on the
terminal block TB2 should be used via either of the NPN/PNP interfaces. Do not use the mixture of the
interfaces for these input or output signals.
The mixture of these interfaces can be used for print target detector signals (pins 1 to 3), encoder signals (pins 6
to 9), input/output signals (pins 4 and 5, 14 to 18), and status output signals (pins 19 to 22).
[Example: You can use the PNP interface for print target detector signals (pins 1 to 3) and the NPN interface for
status output signals (pins 19 to 22).]
