Sealevel Systems, Inc

Since 1986, Sealevel Systems has manufactured I/O products to serve the customers serial and digital interface requirements.

Serial Performance You Can Trust

Sealevels serial products designed using the XR16C850 UART provide 128-byte FIFO, 16 times larger than boards designed with 16C550 parts commonly found on other serial products. This capability allows error free operation even in high-speed applications regardless of the operating system.

The RS-232/422/485 multi-interface Capabilities afford the user maximum flexibility. Choose RS-422 mode for long distance communication up to 4000 feet where noisy immunity and high data integrity are essential. Or, select RS-485 and capture data from multiple peripherals in a RS-485 multi-drop network. The onboard auto-enable hardware automatically handles the RS-485 driver enable allowing the RS-485 ports to be treated as standard serial ports by the operating system. This allows the standard COM driver to be utilized for RS-485 communications.
