I/O Device

Tews TCP461
cPCI	PowerPC	v. 4.0
Multiport Serial I/O

Tews' TCP461 is a standard 3U 32-bit CompactPCI module and offers eight channels of high-performance serial interface.

Three different standard modules are available: The TCP461-10 provides eight RS232 interfaces. The TCP461-11 provides eight RS422 interfaces. The TCP461-12 provides four RS232 and four RS422 interfaces.

Other configurations are available as factory build option on a per channel base.

All modules offer front-panel I/O with a HD50 SCSI-2 type connector. The TCP461-2x modules offer additional J2 rear I/O. Each RS232 channel supports RxD, TxD, RTS, CTS and GND. Each RS422 channel supports RxD+/-, TxD+/- and GND. Two channels of the TCP461-x0/-x2 offer full modem support (TxD, RxD, CTS, RTS, DSR, DTR, CD, RI and GND) for RS232. Two channels of the TCP461-x1 support RxD+/-, TxD+/-, RTS+/-, CTS+/- and GND for RS422.

Each channel has 64-byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 921.6 kbps for RS232 channels and 5.5296 Mbps for RS422 channels. The UART offers readable FIFO levels.

All channels generate interrupts on CompactPCI interrupt INTA. For fast interrupt source detection the UART provides a special global interrupt source register.

All serial channels use ESD protected transceivers up to ±15KV.

The TCP461 can operate with 3.3V and 5.0V PCI I/O signaling voltage.
