Interworld Electronics offers a wide range of Asynchronous and Synchronous Serial Communication Boards and Adapters with the following popular protocols, RS-232, RS-422 and RS-485. Our Serial Communication Boards range from single port to eight ports on a single device, with some devices also having optical isolation which ensures effective data transmission over long communication lines, even in electrically noisy environments. Our solutions with the RS-422 and RS-485 protocols are ideal for industrial applications requiring longer cable runs (up to 4,000 feet).

Interworld’s range covers all major bus architectures including Universal PCI, PCI-Express, mini-PCIe, M.2 and USB. In addition, Interworld offers a range of external serial adapters for RS-232 to RS-422/485 conversion, serial isolators for protecting communications equipment and repeaters for increasing the number of nodes connected to a network.
