Can I use Sealevel synchronous serial adapters with Linux?

  Sealevel SeaMAC software is used to enable Linux support for products which feature the Zilog® Z85230 Enhanced Serial Communications Controller (ESCC). Our Route56 software package should be used to enable Linux support for products that feature the Zilog® Z16C32 Integrated Universal Serial Controller (IUSC). Both software packages are available for download from the Sealevel […]

Can Sealevel synchronous serial expansion boards and Relio R2 Sync Server communicate using SDLC or HDLC-derived protocols?

  Sealevel synchronous serial expansion boards and the Relio R2 sync server have an SDLC mode that implements many low-level behaviors of SDLC such as frame opening and closing flags, frame check sequence calculation and zero-bit insertion behavior. The SeaMAC and Route 56 APIs for these devices provide application software with tight control of the […]

How do Sealevel synchronous serial adapters handle Manchester clock encoded data?

  Manchester clock encoding (also known as split phase or bi-phase level encoding) always produces a transition at the center of the bit cell. Sealevel synchronous serial adapters with the Zilog Z85230 chipset family can receive Manchester encoded data, but cannot transmit it. Sealevel synchronous serial adapters with the Zilog Z16C32 chipset can both receive […]

How does the SeaMAC Configuration Utility help me develop a new application that uses the SeaMAC for Windows API?

  The SeaMAC Configuration Utility lets you easily configure a Sealevel synchronous serial port to the communication options you select. By using the utility to change port options rather than by selecting options within your application code, you can quickly try different port options including bit rate, electrical interface mode, data framing mode, etc. When […]
