Overview
This PC/104 Module features four RS-232 ports via 10-pin connectors.
The full RS-232 interface supports typical serial protocols such as T x D, R x D, RTS, CTS, DTR, DSR, DCD and GND.
With the PCM-3640, you can address COM1 through to COM4 via selectable jumpers and assign individual IRQ for each port (3 to 7, 9 to 12, or 15).
The RS-232 ports on the PCM-3640 can reach up to 115Kbps.
