EXSYS EX-45034 PCIe 4-porttinen sarjaporttikortti RS-232/422/485 (FTDI)

This EXSYS PCIe card stands out by supporting RS-232, RS-422, and RS-485 on all four ports, with auto-toggle transceivers and selectable termination for RS-485. The FTDI FT4232H chipset ensures broad OS compatibility and reliable performance.

Highlights

• 4 serial ports via included fan-out cable with DB9 male connectors
• Supports RS-232, RS-422, and RS-485 standards
• FTDI FT4232H chipset with 256-byte FIFO per direction per port
• High data rates: up to 921.6 Kbps for RS-232, 12 Mbps for RS-422/485
• Low-profile PCIe x1 form factor with standard bracket included
• 15KV ESD protection on all serial lines

In daily use

The card installs in a PCIe x1 slot and provides four independent serial ports, configurable for RS-232, RS-422, or RS-485. Hardware and software flow control are supported, along with flexible data bits, parity, and stop bit settings. RS-485 mode includes auto-toggle transceivers and selectable termination/biasing for reliable multi-drop networks.
