TPMC470

TPMC470 PMC Module 4 Port Serial RS-232/422/485 Controller with Programmable Interfaces

4 channel high performance serial controller with individually programmable RS-232, RS-422, and RS-485 interfaces. All channel are insulated from the system and against each other by digital insulator and on board integrated DC/DC converter. The PMC modules have an operating temperature range from -40°C to +85°C.

The RS-232 channels support RxD, TxD, RTS, CTS and GND. The RS-422 and RS-485 channels can operate in 4-wire full duplex (RxD+/- and TxD+/-) or 2-wire half duplex (Dx +/-) mode. The modules have front I/O via a HD50 connector.

Each channel has 64 byte transmit and receive FIFOs. The FIFO trigger programmable, and the baud rate is individually programmable: up to 921.6 kbps for RS-232 channels, and 5.5296 Mbps for RS-422/485 channels. All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special global interrupt source register. All channels use transceivers with 15 KV ESD protection.

A wide range of drivers for the TPMC470 PMC module is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
