Sealevel synchronous serial adapters enumerate as SeaMAC devices in Windows. Since the devices are zero-indexed, the first installed port will be “SeaMAC0”. SeaMAC devices support…
Why don’t standard asynchronous serial adapters support 9-bit protocols?
Applications that require 9-bit protocols are rare so the chips that support them are more expensive than standard 8-bit UARTs. Most 8-bit UARTs can…
What Sealevel asynchronous serial adapters support 9-bit protocols?
Any Sealevel asynchronous serial adapter that includes a 16C950 UART or 16C954 quad-port UART natively supports 9-bit framing in hardware. USB serial adapters use…
How do I perform a loopback test with my serial adapter configured for 2-wire RS-485?

Can I still order Windows XP Pro for my Sealevel computer?
Windows XP Pro is no longer available on Sealevel computers.
What does Non-Polarized refer to on Optically Isolated inputs?
Non-polarized means that the input trigger condition measures the voltage magnitude across the input, or alternatively the current magnitude through the input, regardless of…
How can I expand the digital I/O in my APC NetBotz appliance?
Sealevel SeaI/O devices offer flexible I/O expansion to APC Netbotz remote environmental monitoring equipment. All APC NetBotz appliances that have a USB port support SeaI/O 450U…
