Describe the basic operating concept of a synchro type remote indicating system.

• A. A remote transmitter uses a radio signal to communicate with a receiver inside the instrument
• B. A remote transmitter electrically signals a receiver inside the instrument by wire
• C. A remote transmitter signals the instrument by infrared light
• D. A remote transmitter transmits via wireless Bluetooth to a receiver

Answer: (B)

Synchro remote indicating systems convey position through a wired electrical link: the remote transmitter converts the mechanical position into a three-phase electrical signal and sends it by wires to a synchro receiver inside the instrument. The receiver interprets those signals and drives the indicator to match the remote’s angle. This is an electrical, wired connection, not wireless, so options involving radio, infrared, or Bluetooth are not part of the basic concept.
