DL TTY – Interface

The system DL TTY forms an asynchronous TTY- interface (20 mA active, half-active or passive) which can be operated in two ways: either half-duplex or full-duplex (please note the schematics opposite).

LEDs and potential-free contacts (optional) of a fault detector relay are able to signal defective states.
