Dual Port RS232/RS422/RS485 "Universal" Serial Communications PCMCIA Card


The SL385 is a unique dual port multi-standard asynchronous serial card for your laptop, PDA, or desktop (using one of Elan's Desktop PCMCIA adapters).  For convenience and flexibility, the SL385 can have each port set individually to RS232 or to RS422/RS485 mode.  Further configurations allow full and half duplex operation, and a choice of RS485 half duplex transmitter enable modes.  The card automatically configures to become two more COM ports by using the built-in O.S. drivers that are tried and tested and are optimized to work in the Windows environment.

Technical Features

Dual 16C550 UART with 16-byte TX and RX FIFOs for high speed and reliable communications.
Switchable RS232 or RS422/RS485 mode on each channel.
Switchable full or half duplex RS485 mode per channel with in-card connection of TX and RX signals in half duplex mode.  RS422 mode includes differential RTS and CTS modem control signals and permanently enabled TX driver and receiver.
Switchable per channel between auto TX enable and RTS override TX enable when in RS485 half duplex mode.
Switchable local TX character echoing when in RS485 half duplex mode (setting common to both ports).
Hardware switchable baud rate multiplier allows either industry standard rates up to 115KBaud in x1 mode or up to 921Kbaud in x8 special drivers needed for faster rates (setting common to both ports).
Full fail-safe open/short circuitry on RS485 inputs.
Supports 5/6/7/8 data bits, odd/even/no parity, 1/1.5/2 stop bits, baud rates including 2400, 4800, 9600, 19200, 57600, 115200 in x1 mode, and 8 times these rates in x8 mode i.e. up to 921600 baud.
