TCP461

8 Channel Serial Interface RS232/RS422

Application Information

The TCP461 is a standard 3U 32 bit CompactPCI module

and offers 8 channels of high performance asynchronous

serial interface.

Three different standard modules are available: The

TCP461-x0R

provides

8

RS232

interfaces.

The

TCP461-x1R

provides

8

RS422

interfaces.

The

TCP461-x2R provides 4 RS232 and 4 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 TCP461-2xR 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-x0R/-x2R offer full modem

support (TxD, RxD, CTS, RTS, DSR, DTR, CD, RI and

GND) for RS232. Two channels of the TCP461-x1R

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.
