The features of the PMC-SIO 8-port serial I/O board include:

Two full-featured 85230 ESCC ports
– EIA-422/485 interface
– Supports synchronous/isochronous/asynchronous protocol (TXD/RXD, RTS/CTS, DCD, RXC, SG, TXC, and TC [TXC-out])
– Up to 3.6864 Mbps
– Synchronous modems
– Multidrop full and half duplex with RTS flow control

Two “multi-PHY” 85230 ESCC ports
– EIA-422/485 interface
– Synchronous/asynchronous protocols (TXD/RXD and SG)
– Up to 3.6864 Mbps
– Multidrop full and half duplex with RTS flow control

Four asynchronous-only 16550-type ports

The new PMC-SIO board provides both front and rear I/O and is available in versions for convection-cooled (SA and RA class) or conduction-cooled (RC class) environments. The PMC to PCI interface on the PMC-SIO uses a 33 MHz, 32-bit PLX PCI9030, with 3.3V or 5V signaling and a configuration serial EEPROM. The new PMC-SIO is provided with a VxWorks Board Support Package.

The PMC-SIO is ideal for applications requiring extensive serial input/output for the management and monitoring of peripherals. The ruggedized version of the board is well-suited to handle the rigors of military and aerospace applications. Because the PMC-SIO board is designed for use with current and next generation architecture, it allows for universal PCI signaling voltages.
