Setting the DIP Switch The operation of High-density I/O Units is controlled by setting the pins of the
DIP switch on the back panel. The following table shows the function of each pin
and applicable Units.

Note 1. Used in the C200H-MD501/MD115/MD215 only when pin 1 is OFF, setting
the Unit to static mode.
2. Used in the C200H-ID501/215, C200H-MD501/MD215/MD115/MD215
only when pin 2 is ON, setting the Unit to High-speed input mode.
3. Sets the input response time for normal inputs. When pin 2 is ON, CN2 08 to
15 are pulse-catch inputs. Other inputs can be used as normal inputs.
4. Used when pin 1 is ON, setting the C200H-OD501/OD215 to dynamic out-
put mode.
