TPMC866 8 Channel Serial Interface Module
The TPMC866 is a standard single-width 32 bit PMC module and has eight channels of high performance serial interface with front I/O and back I/O. The TPMC866-10 offers an 8 channel RS232 interface and supports Receive Data (RxD), Transmit Data (TxD), Ready-To-Send (RTS), Clear-To-Send (CTS) and GND for each channel. Additionally serial channel one and serial channel two provide Data-Set-Ready (DSR), Data-Terminal-Ready (DTR), Data-Carrier-Detect (DCD) and Ring-Detect-Indicator (RI). The TPMC866-11 supports an 8 channel RS422 interface and offers RS422 signal levels by differential transmitters and receivers. The Transmit data (TxD +/-), Receive Data (RxD +/-) and GND are provided for each serial channel. The receiver signal termination (120ohms between RxD+ and RxD-) is provided on the TPMC866 per channel. Each channel of the TIP866-10/11 has a 64 byte transmit FIFO and a 64 byte receive FIFO to significantly reduce the overhead required to provide data to and get data from the transmitter and receivers. The FIFO trigger levels are programmable. The TPMC866-12 provides an 8 channel of high performance serial interface. Each serial channel can be configured by a DIP-switch to operate as an RS422, RS485-FD-M (Full Duplex Master), RS485-FD-S (Full Duplex Slave) or RS485-HD (Half Duplex) interface. For RS422 and RS485-FD a four wire interface (RX+, RX-, TX+, TX-) plus ground (GND) is offered. For RS485-HD a two wire interface (DX+, DX-) plus ground (GND) is supported. For the front I/O a HD50 female connector is located in the front panel. For the back I/O the P14 I/O connector is supported. Each channel of the TIP866-12 has a 128 byte transmit FIFO and a 128 byte receive FIFO to significantly reduce the overhead required to provide data to the transmitters and get data from the receivers. The FIFO trigger levels are programmable. For all modules the baud rate is individually programmable up to 460.8Kbaud per channel. All channels use the PCI interrupt INTA together but for fast interrupt source detection the TPMC866-xx provides a special interrupt status register. Receiver and transmitter are protected against electrostatic discharge (ESD). Technical Specifications
