Multiport Serial I/O

The TPMC860 is a standard single-width 32 bit PMC module with four channels of high performance RS232 interface. Each of the four channels is isolated from the system and against each other by optocoupler and on board DC/DC converter per channel.

The serial channels are accessible through a DB25 connector mounted in the front panel and via P14 I/O. Each channel 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 TPMC860 supports Receive Data (RxD), Transmit Data (TxD), Ready-To-Send (RTS), Clear-To-Send (CTS) and isolated GND per channel. The baud rate is individually programmable up to 460.8kbaud for each channel. Interrupts are supported.

All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the TPMC860 provides a special interrupt status register.

Each RS232 receiver input and transmitter output is protected against electrostatic discharge (ESD) up to +/- 15kV according to IEC 1000-4-2.
