Sealevel provides a synchronous serial driver, SeaMAC V4, 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 V4 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 Files\SeaMAC V4\Samples\.

Sealevel synchronous serial products fall into three categories: ZiLOG Z16C32 based devices, ZiLOG Z85230 based devices and older ISA DMA channel cards. The fastest family of Sealevel synchronous serial products is built around the ZiLOG Z16C32 IUSC which…

The Z85230 PDF user manual and the Z16C32 PDF user manual are both available on the ZiLOG web site and are used on a variety of Sealevel synchronous serial products.

Sealevel provides WinSSD, a helpful software utility that allows easy verification your synchronous card is working properly. After you install the SeaMAC V4 synchronous software driver onto your system, WinSSD will be located in the SeaMAC folder in the…

For Sealevel synchronous serial products, after connecting the Transmit (TX) and Receive (RX) pins, you will need to connect the Clock Output pin (TSET) to the Clock Input pin (RXC). In most cases, the Clock Output pin (TSET) should be used as the board's…

The 'Set Configuration' and 'Save Configuration' buttons are only available in the synchronous version of WinSSD test utility that is included in the SeaMAC software suite. Clicking the 'Set Configuration' button will send the configuration currently defined…

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 additional features that are not typically found on asynchronous serial…

In Windows Device Manager, Sealevel synchronous serial adapters will install under the ‘SeaMAC Device’ category. The device names for Sealevel synchronous serial adapters, with part numbers in parenthesis, are shown as they appear in Device Manager. PCI…

Section 2.5 of the ITU O.151 document basically states that a pattern can be encapsulated by the framing bits of a protocol, if necessary. Therefore, the BERT pattern can be used in a synchronous mode, such as SDLC/HDLC, as well as asynchronous mode.
