The PCI325 is an RS-422 synchronous/asynchronous multiport serial adapter. The module can accept a clock input to synchronize the baud rate generators of each port to an external clock. All the protocol management overhead is taken care of in the hardware so that the host CPU is offloaded from managing the detailed serial protocol.
The hardware is re-programmable which enables the board to be repurposed for different types of synchronous and asynchronous serial applications. The hardware takes care of all bit-serial receive/transmit activity and uses a convenient, high-performance, low-overhead, packet-based interface to the host CPU which supports batching and queuing of input/output bits.
An I/O breakout box may be connected to the high-density connectors of the PCI325 to provide multiple DB25, DB9, or other serial connectors for easy integration to your system or an octopus-style breakout cable may be used. The I/O breakout box may include many different status LEDs which can be tailored to your protocol/application. The PCI325 provides the breakout box with power so that it does not require any additional power cabling.
