The DNx-SL-501 is a 4-port serial communications board (layer) for PowerDNA distributed automation and control system. This board (layer) offers isolated serial interfaces software-configurable as RS-232 or RS-485. DNx-SL-501 supports up to 2 Mbit/s transfer speed in RS-485 mode or up to 256Kbit/s in RS-232 mode. DNx-SL-501 uses 16550 UART controller on each port (FIFO mode only) and supports half- and full-duplex mode for RS-485.

The DNx-SL-501 includes the UEI-RSS Remote Serial Server application, Windows and Linux versions. This server allows a Windows or Linux host PC to configure the DNx-SL-501 ports as standard serial ports within the host OS (e.g. as COM1: to COM255: ports in Window or standard POSIX functions in Linux). The UEI-RSS supports up to 255 unique serial ports per Ethernet port on the host.
