Control with External Signals (Continued)
Input Signal and Photocoupler
The input signal from the external control connector turns the photocoupler
inside the Control Unit ON and OFF to set and write data. The input signal is
compatible with both the sinking and sourcing devices.
For a sinking device, the photocoupler is OFF when the input signal is high, and
for a source type, the photocoupler is ON when the input signal is high.

* The response times of the 24V LIGHT and the HLV LIGHT connectors are very different.
* If the data is rewritten during the response time for the light set value, the start of the rewrite that was input again is reset as the starting point.
