Adopt high?speed optocoupler isolation conversion, baud rate range 300115200bps.. Each communication port has TVS protection, easy to use and safer.. TTL supports 3.3V, 5V factory mode is 3.3V, it can realize TTL to 232, TTL to 485(2), TTL to 422(2), 485(1) to 232, 485(1), 485(2) 485 Relay, 485(1) to 422(2), 422(1) to 232, 422(1) to 485(2), 422(1) to 422(2)422 repeater, so the conversion is two?way co. Small size, easy to carry and store, convenient to use and with good performance.. Made of high-quality materials, strong and durable, has a long service life..
