Note
1. Refer to the Unit’s
Operation Manual
for details on I/O bit allocation.
2. The Unit will have 128 dynamic output points when pin 1 of it’s DIP switch is ON.
3. Set pin 5 of the Unit’s DIP switch ON for positive logic outputs, or OFF for negative logic outputs. When
set for negative logic outputs, the terminal has an “L” voltage level when there is an output. When set for
positive logic outputs, the terminal has an “H” voltage level when there is an output.
4. The strobe signal has negative logic regardless of the setting of pin 5.
5. When the output device (such as a numeric display) does not have a pull-up resistor, it is necessary to
add a pull-up resistor between the + terminal of the power supply and each data (0 to 15) and strobe (0 to
15) terminal.
