❓ Frequently Asked Questions
What is the difference between RS422 and RS485?
RS422 supports full-duplex communication (simultaneous send/receive) and is ideal for point-to-point connections. RS485 supports half-duplex (one direction at a time) and allows multi-point connections with up to 128 devices on the same bus.
Do I need to install drivers?
Yes, FTDI drivers are required for proper operation. Download the driver package from the link at the top of this page.
What is the maximum cable length?
For RS422/RS485 connections, you can achieve up to 1200 meters at 9600 bps. Higher baud rates will reduce the maximum distance. The USB cable should not exceed 5 meters for reliable operation.
Can I use all 8 ports simultaneously?
Yes, all 8 serial ports can operate simultaneously. The adapter supports concurrent communication across all ports with independent baud rate settings for each port.
What power supply do I need?
The adapter comes with a DC 5V power adapter. Alternatively, you can use the terminal block for 9-36V DC power supply, making it suitable for industrial environments with various power standards.
Is this compatible with Linux and Mac?
Yes, the FTDI chipset is compatible with Linux 3.2+, Mac OS X, Windows (XP through 10), Android, and Windows CE. FTDI provides native drivers for all major operating systems.
What type of cable should I use for RS485 connections?
Use twisted-pair cable or shielded cable for best results. Shielded cable is recommended in electrically noisy environments to minimize interference and ensure reliable data transmission.
Does it support hot-swapping?
Yes, as a USB device, this adapter supports hot-swapping. You can connect or disconnect it while your computer is running without needing to restart the system.
