Serial Adapters & Converters

Whether you require one serial port or 16, our USB Serial Adapters will have you quickly communicating with RS-232, RS-422, and RS-485 peripherals.

Unlike traditional UART-based devices, SeaLINK USB products use a state-machine architecture that reduces host processor overhead for faster, more reliable communications.

Our Isolated USB to Serial Adapters are designed to protect expensive computing hardware via it's on-board optical barrier. Their isolated protection provides immunity from ground loops and surges.

SeaLINK Embedded USB Serial Adapters mount directly to a computer chassis using an open PC bracket location and interface to the host computer via a USB motherboard header.

The adapters eliminate the need for external converters and provide a clean, professional installation.

Internal USB cables are available for a variety of motherboard and industrial SBC form factors.

Our range of Ethernet Serial Servers offer the easiest way to connect RS-232, RS-422, and RS-485 serial devices to your Ethernet network.

All SeaLINK devices use industry standard TCP/IP protocols enabling any host to access serial ports as virtual COM ports. Designed using a powerful embedded microprocessor, these products are able to communicate over multiple ports at sustained data rates up to 230K bps.

Our Isolated RS232 / RS485 Converters and Fibre Optic Modems are designed to "harden", protect and extend operating ranges using the standard RS232 / RS485 protocol and specifications. Their isolated protection provide immunity from ground loops and surges.

Our Serial Interface Converters allow a standard RS-232 port to communicate with an individual RS-422 device or multiple RS-485 devices.

Full duplex and half duplex modes are supported.
