PORTWELL Industrial Partner

Portwell LPCI-COM485-8 Serial Communication Port Card that can be installed in any 3.3V or 5V PCI slot computer. Supports RS-485 protocol with auto RS-485 control under all OS at baud rates up to 921Kbps Simple Type: Communication Card

These are eight-port, asynchronous, serial communication cards designed for use on the PCI bus. They support RS-485 and RS-422 communications. The cards are ¾ length and may be installed in any 5-volt PCI slot in IBM and compatible personal computers. Normally, these units are supplied with an eight-connector breakout cable. However, they are available without that cable as models PCI-COM485/8S1 and PCI-COM422/8S1. Type 16550 UARTs are used as the asynchronous communication elements. These include a 16-byte transmit/receive FIFO buffer to protect against lost data in multitasking systems while maintaining 100 percent compatibility with the original IBM serial port.
