Question 1 of 27070

The current and most recent version of NMEA 0183 uses what standard for data communications?

🔍 Key Concepts

• NMEA 0183 is a serial data communication standard used in marine electronics • The electrical layer of NMEA 0183 is based on an existing EIA/Recommended Standard (RS) interface • Compare how single-ended vs. differential signaling works in common RS interfaces

💭 Think About

• Which RS standard is commonly used for noise-resistant, differential signaling over longer cable runs—something very important on boats? • Think about which RS standard NMEA 0183 originally referenced, and whether the "current and most recent" version still aligns with that or has fully changed to a different one. • Which option is primarily used for point‑to‑point, short distance connections (like old PC serial ports), and is that ideal for a vessel environment?

✅ Before You Answer

• Identify which choice corresponds to a differential, balanced line standard commonly recommended for marine environments. • Eliminate any option that is mainly associated with single‑ended, short cable, computer COM ports. • Confirm which RS interface the official NMEA 0183 documentation cites as its primary physical layer recommendation.
