6.2.1.9 Digital Input
Digital Input feature is available only for TTL ready (optional) controller.
TTL feature allows to change setpoint between two specified values using a TTL signal. The TTL is a digital
input for our Units and has only two values: High and Low. The setpoint values for High TTL value and for
Low TTL value can be set using OKO-TOUCH, via GPIO connector.
When TTL Control is enabled, the user cannot change the setpoint using the dialog in the main page. In this
case, the setpoint value is read by the external TTL signal.
