Application Information
The TPMC462 is a standard single-width 32 bit PMC
module and offers 4 channels of high performance
asynchronous serial interface.
Three different standard modules are available: The
TPMC462-10R provides 4 RS232 interfaces. The
TPMC462-11R provides 4 RS422 interfaces. The
TPMC462-12R provides 2 RS232 and 2 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 and P14 I/O. Each RS232 channel supports
RxD, TxD, RTS, CTS and GND. Each RS422 channel
supports RxD+/-, TxD+/- and GND. One channel of the
TPMC462-10R/-12R offers full modem support (TxD, RxD,
CTS, RTS, DSR, DTR, CD, RI and GND) for RS232. One
channel of the TPMC462-11R 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 PCI interrupt INTA. For
fast interrupt source detection the UART provides a
special Global Interrupt Source Register.
All serial channels use ESD protected transceivers. ESD
protection is up to ±15KV.
The TPMC462 can operate with 3.3V and 5.0V PCI I/O
signaling voltage.
Software Support (TDRV002-SW-xx) for different
operating systems is available.
