1.rs232 levelOr the serial level, some even say the computer level, all these statements, refers to the computer 9-pin serial port (RS232) level, using negative logic,-15v ~ -3V Rep 1+3V ~ +15v Rep 02.rs485 and RS422 levelSince both use differential

What is TTL level, what is CMOS level, their difference(1) TTL High Level 3.6 ~ 5 V, low 0 V ~ 2.4 VCMOS-level VCC can reach 12 VThe output height of the CMOS circuit is about 0.9vcc, while that of the output low is about0.1vcc.The input that is not

TTL:(Time to live) life time is a value in the IP protocol package. It tells the network router package whether the time in the network is too long and should be discarded. There are many reasons that the package cannot be delivered to the

Point:1. Serial Port and comport are physical interfaces (hardware ). While TTL, RS-232, RS-485 refers to the level standard (electrical signal ). 2. Generally, only Gnd RX Tx is connected to the device. Do not connect to the VCC or + 3.3v power
