Lava Single Port Serial Card interface cards/adapter

Single Port Serial Card (PCI Bus 16550) Easy to install and configure, the LAVA RS422 SS-PCI adds a high-speed RS-422 serial port to any PCI-equipped PC.
The RS-422 SS-PCI's strength lies in its Moko S-1 ASIC (Application-Specific Integrated Circuit). This chip-only available on LAVA products-consolidates a number of separate components into one chip. This adds efficiency in manufacture, and more importantly, virtually eliminates any possibility of component failure.
This tried and true board is compatible with any RS-422 serial peripheral and provides the most convenient way of connecting PCs to industrial and factory automation equipment, security and data monitoring devices, and other equipment using the RS-422 serial interface.
