|The PLCP0052 High Performance Serial Card is an OPTO-ISOLATED RS-422 4-wire/ RS-485 2-wire serial port adapters. The card has an onboard 200 mA DC/DC converter eliminating the need for an external power supply. The Card is equipped with a wait state generator to accommodate very high speed busses or low frequency oscillator. The onboard serial controller, an enhanced version of the industry standard 8250A UART allows for improved throughput. The on chip FIFO, and the extensive check done on the incoming characters, reduces the CPU overhead allowing baud rates unachievable with "standard" devices. The Card is designed to plug directly into a standard PC/PC-AT slot and will run all the standard software written for the PC.|
