The CA-108-T module from the CA-108 Series is an 8-port RS-232 serial module designed for PC/104 bus systems and built to operate reliably in extreme industrial environments from -40 to 85°C. Equipped with four 16C550C-compatible UARTs and 64-byte FIFOs, it supports baud rates up to 921.6 kbps across all ports.

DIP switches allow for the manual configuration of I/O base addresses and IRQ settings, while each port features built-in Tx/Rx LEDs for direct status monitoring. With driver support for Windows, Linux, and UNIX, the CA-108-T integrates easily into a wide range of embedded applications.
