TEWS TECHNOLOGIES today announced the TPMC460, a new 16 channel asynchronous serial PMC module, designed for applications in transportation, military/aerospace, communications, and process control.
The TPMC460 is available with RS232, RS422, or mixed RS233/422 channels and features 16 total channels. Each RS232 channel supports RxD, TxD, RTS, CTS and GND. Each RS422 channel supports RxD±, TxD± and GND. All versions offer front panel I/O with a HD68 connector and P14 I/O.
A transparent 32 bit / 66 MHz PCI-to-PCI Bridge provides access to the two Exar XR17D158 octal PCI-UARTs. The PCI-to-PCI Bridge allows 32 bit accesses on the local PCI bus and permits the high data throughput necessary for the high performance serial interfaces.
In order to offload host CPU processing, each channel has 64-byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and 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.
Software support for major operating systems such as Windows, Linux, VxWorks, and QNX is available.
