Interworld Electronics has release the ACCESS I/O range of communication boards for the Universal PCI, PC/104 and the USB bus. A wide range of RS-232, RS-422/485 and Multi-protocol RS-232/422/485 boards are available. Boards with Optical Isolation are also available for industrial environment where heavy machinery can cause power-switching transients that can permanently damage un-protected communication boards.

The PC/104 bus 104-COM232 Series is available with 2, 4 or 8 RS-232 ports while the 104-COM-xSM Series provides 4 or 8 RS-422/485 ports. Multi-protocol field selectable RS-232/422/485 PC/104 modules are also available.

The ACCESS I/O range of Universal PCI and Low Profile Universal PCI communications boards includes the PCI-ICM-2S dual port Optically Isolated RS-422/485 card and the LPCI-COM-4SM 4-port Multi-protocol field selectable RS-232/422/485 board. The LPCI-COM-4SM incorporates a 16L788 octal UART that provides 64 Byte FIFO buffers in all modes and can operate at speeds up to 921 Kbps.

If your system lacks expansions slots then the USB bus USB-422/485 provides 4-wire full duplex RS-422 or 2-wire half duplex RS-485 communications. If you need full Multi-protocol support then the USB-FLEXCOM4 provides four field selectable RS-232/422/485 serial ports in a compact low profile enclosure.
