Interworld Electronics supplies a wide range of Asynchronous Serial Communications Boards. The range includes RS-232, RS-422 and RS-485 protocols boards with single, dual and multi-port options. Connectivity options include PCI, Universal PCI, PCI-Express, PC/104 and ISA bus architectures.

 Communication Boards
PC/104 Bus
PC/104 Bus: PC/104 is a compact implementation of the ISA PC bus. Interworld carries a large range of RS232 and RS422/485 serial communications PC/104 modules with single, dual, quad or eight independed asynchronous serial ports. High speed synchronous serial PC/104 modules are also available.

PCI / PCI-X Bus
PCI / PCI-X Bus: Interworld Electronics supplies a wide range of Asynchronous PCI, Universal PCI and PCI-X Bus Communications Boards. The range includes RS-232, RS-422 and RS-485 protocols boards with single, dual and multi-port options.
PCI-Express
PCI-Express: PCI Express is the new standard in Serial Connectivity. PCI Express cards are available in 2 to 32 port serial card configurations and offer high-speed, serial I/O that maintains backward compatibility with PCI applications and drivers.
