1.1 Definitions
A current loop interface transmits serial data by switching on and off a 20mA
current in a conductor loop at the data bit clock. During the rest condition, or
during transmission of ”1” bits, a constant 20 mA current is flowing, whilst the
current flow is intermittent with ”0” bits.
Another name for 20mA current loop interface is TTY interface
(TeleTYpe(writer)).
