Page 14: Technical Description
Technical Description The Sealevel Systems 7802ec provides a PCIe interface adapter with eight (8) asynchronous serial ports providing versatile RS-422/485 interfaces for industrial automation and control applications. The 7802ec provides UARTs with 256 byte TX and RX FIFOs, programmable baud rates, data format, and interrupt control. - Page 15 Please terminate any unused control signals. The most common way to do this in RS-422/485 mode is to connect RTS+ to CTS+ and RTS- to CTS-. Terminating these pins, if not used, will help ensure the best performance from the adapter. © Sealevel Systems, Inc. 7802ec &7802ecS Manual | SL9680 11/2022...
