Sealevel 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. Optically isolated versions are available providing immunity from ground loops and surges. Sealevel serial interface converters are available in extended temperature versions and OEM versions without enclosures.
Sealevel continues to provide a full line of ISA serial and digital I/O products to support legacy applications. All of our quality products come with a Lifetime Warranty that guarantees the performance of our components over the life of the product.
Designed to meet the core needs of PC/104 applications requiring high reliability, small size, and long-term availability, Sealevel PC/104 digital I/O modules offer easy installation and robust software support.
Easily add one or two serial ports via PCMCIA expansion slots. The flexible 3623 PCMCIA serial interface card provides two serial ports individually configurable for RS-23, RS-422 or RS-485. The card implements all modem control signals for maximum compatibility with a wide range of peripherals. The 3604 uses a high-speed UART with 128-byte FIFOs and supports RS-232 data rates at 460.8Kbps.
Sealevel 3U Compact PCI boards are available with RS-232, RS-422, and RS-485 serial interfaces. An optically isolated multi-interface version protects the host backplane from ground loops and transient voltages common in industrial environments. Sealevel Compact PCI serial boards are available in extended temperature versions.
