AJMRTC isolated multi-serial converter is an industrial-grade communication module built around original FT232RL. It realizes flexible cross-bus conversion: USB to RS232 / RS485 / TTL, RS232 / RS485 / TTL to other serial standards. The isolation design separates the host side and field bus side, effectively suppressing common-mode noise. It supports virtual COM port under Windows, Linux, MacOS and Android. Baud rate ranges from 300bps up to 3Mbps, compatible with Modbus RTU and most custom serial protocols. Aluminum casing improves heat dissipation and shielding. Widely used for PLC debugging, energy meter reading, sensor data acquisition and industrial serial bus networking.
