I/O Device

Tews TCP462
cPCI	PowerPC	v. 4.0
Multiport Serial I/O

Tews' TCP462 is a standard 3U 32-bit CompactPCI module and offers four channels of high-performance serial interface.

Three different standard modules are available: The TCP462-10 provides four RS232 interfaces. The TCP462-11 provides four RS422 interfaces. The TCP462-12 provides two RS232 and two 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 TCP462-2x 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. One channel of the TCP462-x0/-x2 offers full modem support (TxD, RxD, CTS, RTS, DSR, DTR, CD, RI and GND) for RS232. One channel of the TCP462-x1 supports 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 TCP462 can operate with 3.3V and 5.0V PCI I/O signaling voltage.
