TCP469, TCP470 3U CompactPCI 4 or 8 Port Serial RS232/422/485 Controller with Programmable Interface

3U CompactPCI 4 or 8 port serial RS232/422/485 controller with programmable interface. The TCP469 and TCP470 have individually programmable RS232, RS422, and RS485 interfaces. The TCP469 has 8 channels and the TCP470 has 4 channels. All channel are insulated from the system and against each other by digital insulator and on board integrated DC/DC converter. The modules have an operating temperature range from -40°C to +85°C.

The RS232 channels support RxD, TxD, RTS, CTS and GND. The RS422 and RS485 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 thresholds, and the baud rates are individually programmable: up to 921.6 kbps for RS232 channels, and 5.5296 Mbps for RS422/485 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 is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
