Isolated RS-485/422 Octal UART PMC

PSCC –1008E is an octal isolated asynchronous serial communication controller based on a PMC form factor.

The PSCC-1008E module is compatible with the PCI specification 2.2 and run on 32-bit bus size at 33 MHz frequency. Data transfers operation can be formatted in 8-bit, 16-bit, 24-bit or 32-bit wide.

The PSCC-1008E provides 8 enhanced 16C550 (5th generation) UARTs with the PCI Bus interface. Half and full duplex mode are supported for point-to-point and multi-drop network configuration.

Each UART has its own 64 Byte of transmit and receive FIFO, a set of 16550 compatible control and status registers, and a baud rate generator for individual channel data rate setting.

Each channel is 2.5 KV isolated. Isolators used provide performance superior to alternatives such as optocoupler devices.

All channels are available on front panel (SCSI 68-pin connector) and on rear I/O connector (P4). The rear I/O connector can be use if the host card is designed for isolated signals.

The PSCC-1008E can running on major real-time operating systems and with the open-source Linux™ or VxWorks operating systems.
