Is this device compatible with my operating system?
Yes. It supports Mac, Linux, Android and Windows 7 through Windows 11.
Can I use RS232, RS485 and TTL interfaces at the same time?
No. The unit is a multi protocol converter but only one interface can be converted to USB at a time; RS232, RS485 or TTL cannot be mixed or cross converted.
Do I need an external power supply for this converter?
No external power supply is needed as the device provides onboard isolated power for the isolated terminal.
What protective and isolation features are included?
It includes onboard TVS, ESD protection, a self recovery fuse and protection diodes, and unibody digital isolation for high reliability and low interference.
What baud rates are supported by this converter?
Baud rates vary by chip. FT232RL supports 300 bps to 921600 bps on RS232 and up to 2 Mbps on TTL and RS485; CH343G supports up to 600000 bps on RS232 and up to 2 Mbps on TTL and RS485 (not full band).
