１７．Connection diagram for BCD input (Option:BI )
1.
The Binary Coded Decimal code is the NPN opening collector pulse output. In addition,
it becomes all figure parallel output.
2.
The input logic of data is modifiable. （Please refer to P.33 Mode No. F）
Hi active ：Each pin of input data is in condition to open with GND.
Low active ：Each pin of input data is in condition to short with GND.
3. Latch input・・・I prohibit the uptake of data.
Therefore, I hold data when I wore a latch
even if the later input data change. When I want to update data, I turn off
a latch (Uptake possibility) and take in data, and ON does a latch
(Uptake prohibition) again.
Latch(Short)：When Latch(Pin 37) and
“
GND
”
are in a short state, I prohibit the uptake of data.
Latch(Open)：When Latch(Pin 37) and
“
GND
”
are in a open state, I prohibit the uptake of data.
