18. BCD INPUT
1. BCD code is all-digit parallel input at NPN open collector pulse input.
2. Input logic of data can be changed.(Refer to P42)
Hi Active : Each input terminal and GND are open.
Low Active : Each input terminal and GND are open.
3. Latch Signal Input
Data is not input when latch signal is input.
0 : Latch on short - Data is not input when latch signal pin (37pin) and GND are short.
1 : Latch on open - Data is not input when latch signal pin (37pin) and GND are open.
4. When this option is selected, D-sub37P male connector (XM2A-3701) and Hood (XM2S-3711) are attached
by the addition.
