3U CompactPCI isolated asynchronous serial I/O modules for military COTS introduced by TEWS Technologies



HALSTENBEK, Germany, 21 Jan. 2011. TEWS Technologies GmbH in Halstenbek, Germany, is introducing two 3U CompactPCI isolated asynchronous serial I/O modules for applications in military COTS, transportation, communications, and industrial process control. The TCP469 and TCP470 32-bit 3U CompactPCI board products offer eight- or four-channel high-performance serial interfaces.


Each serial channel can be programmed via a CPLD register to operate as an RS232, RS422 or RS485 interface. The RS422 and RS485 interfaces can be programmed as Full Duplex or Half Duplex interface with programmable termination. The modules can operate with 3.3- and 5-volt PCI I/O signaling voltage.

Each RS232 channel supports RxD, TxD, RTS, CTS and GND. RS422 and RS485 full duplex support a four-wire interface (RX+, RX-, TX+, TX-) plus ground (GND). Half Duplex supports a two wire interface (DX+, DX-) plus ground (GND). All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special Global Interrupt Source Register.

The modules offer front panel I/O with a HD50 SCSI-2 type connector. Each of the channels are isolated from the system and against each other by digital isolator and on board integrated DC/DC converter. The TCP469 and TCP470 operate in temperatures from -40 to 85 degrees Celsius.
