RS232/RS422/RS485/UART trigger and analysis
The RS232 protocol analyzer option can analyze the RS232, RS422, RS485 and UART buses. When the user
selects RS232 bus, the input polarity will be set to Normal. When the user selects RS422 bus, RS485 bus or
UART bus, the input polarity will be set to Inverted. The RS232 bus is made as an example to introduce the bus
option hereinafter.
The RS232 bus is composed of sending data line (Tx) and receiving data line (Rx). Each frame of data is
composed of Start Bit, Data Bit, Check Bit and Stop Bit, which will be triggered on Tx start bit, Rx start bit, Tx
end of packet, Rx end of packet, Tx data, Rx data, Tx parity error, and Rx parity error.
