🔍 Key Concepts

• Carefully read the pin descriptions in figures A and B of the DB‑25 connector diagram • Distinguish between transmit (output) data and receive (input) data lines on RS‑232 • Remember that in RS‑232 terminology, the output from your device is usually labeled TxD (transmit data)

💭 Think About

• On the right‑hand list, which pin number is explicitly labeled as carrying transmit data? • In figure A, which labeled contact corresponds to the line that sends data out of the device rather than into it? • Compare the label for transmit data with the labels for receive data and clock signals to avoid mixing them up

✅ Before You Answer

• Verify which pin label includes the word Transmit or abbreviation TxD • Double‑check that you are not choosing the pin for Receive Data (RxD), which is input, not output • Confirm that you are not confusing data lines with clock lines such as Transmit Clock In/Out or Receive Clock In/Out
