Rs232 signal format
WebOct 20, 2024 · The RS232 Serial Interface is designed to connect two devices. The protocol enables communication between a single transmitter and receiver. Using an RS485 interface, up to 32 serial devices can be connected to one transmitter. Making effective use of serial devices often involves converting between RS232, RS485, and USB signals. WebJan 15, 2024 · On the RS232 side, (DB09 connector) connect pin 2 to pin 3. On the TTL side, TX pin through a 220 Ω (prevents accidentally damaging things) to 5v then to 0v. On the TTL side, measure the voltage on RX (should go 5v then 0v). Edit You may have a bad pin on the Arduino. Try different pins for mySerial. LarryD January 14, 2024, 7:07pm 9

WebRS-232 signals usually range between -13V and 13V, though the spec allows for anything from +/- 3V to +/- 25V. On these signals a low voltage (-5V, -13V, etc.) indicates either the idle line, a stop bit, or a data bit of value 1. A high RS-232 signal means either a start bit, or a 0-value data bit. That's kind of the opposite of TTL serial.
