Description
Tu300LoopDriver.kicad_pcb
The Flesher TU-300 and TU-170A Teletype terminal units have an EIA232 interface and a TTL interface, but do not have a current loop interface. This board provides a floating current loop interface for these terminal units, plugging into the rear panel P2 connector, which is the TTL interface.
Design details are at https://w6iwi.org/rtty/tu300/LoopDriver/ . Further information on the Flesher TU-300 is available at https://w6iwi.org/rtty/tu300/ .
