The EX-45032 PCI I/O card provides two serial RS-232, 422, and 485 high-performance UART 16C550 outputs. It is designed to expand two additional serial ports for PCs, workstations, or servers via the PCI or PCI-X bus. +5V and +12V can be configured on pin 9 of the serial connector as a POS system (Power over System). The card is fully Plug-and-Play compatible. It supports ATTA Auto RS-485 transmitter features. The transmission type (RS-232, 422, or 485) can be individually set for each port.
