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 […]
The ITU document O.153 paragraph 2.1 indicates the BERT pattern can be used at data rates up to 14.4 Kbps. However, the Sealevel WinSSD utility allows the BERT pattern to be used at all available data rates and supported communication modes, including those above 14.4 Kbps.
SeaMAC V5 automatically installs application samples with source code in the ‘Samples’ subdirectory. In Microsoft Windows 7, Vista, XP and 2000 operating systems, samples are located on your hard drive under C:Program FilesSeaMAC V5Samples.
Sealevel provides WinSSD, a helpful software utility that allows easy verification your synchronous card is working properly. After you install the SeaMAC V5 synchronous software driver onto your system, WinSSD will be located in the SeaMAC folder in the Start menu. To verify operation of your card, launch WinSSD, open the port and then […]
Sealevel provides a synchronous serial driver, SeaMAC V5, to interface our synchronous serial adapters to your computer. No additional DLL or library files are necessary for basic operation. For advanced configuration, status and control features, use the SeaMAC V5 API. The supplied C-language header files define the functions and structures of the SeaMAC V5 […]
The WinSSD utility of SeaMAC for Windows gives you access to all the communication options of Sealevel PCIe and PCI synchronous serial cards necessary to create a loopback test. This includes many options you can combine for a valid communication configuration, and the options to electrically join the data transmit and data receive signals […]
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 […]
Sealevel synchronous serial adapters are capable of a constant output stream if the application program can provide a constant stream of serial data. If you are using either blocking (normal) I/O or overlapped I/O with only one write active at a time, then the adapter will run out of data to send when the […]
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 […]
