Eight Channel RS422 Serial PMC

The PMC450 is a flexible solution for integrating multiple serial I/O channels onto a Single Board Computer (SBC), VMEbus, or CPCI system.

The PMC450 is a FPGA-based eight channel RS422 serial PMC card with front and rear I/O. The standard configuration consists of a PCI-core and eight 16C550-uart compatible cores. With the 32 onboard RS422 transceivers, eight serial RS422 channels (Rx, Tx, RTS and CTS) are created. The PMC450 features a 68-pin high dense connector at the front for the connection of all the RS422 channels. A PIM (PMC I/O Interface) for rear I/O is optional. Usage in ruggedised systems with conductive cooling is also possible.

Because of the fully FPGA-based design, custom protocol interfaces for RS422 and RS485 are available on request, including serial I/O, encoder interfaces, stepper motor controllers and more.
