What are the differences between the HGuide HG4930 SDLC and Non-SDLC?

What are the differences between the HGuide HG4930 SDLC and Non-SDLC?

Synchronous Data Link Control (SDLC) is a legacy high reliability format that sends out data when a clock is turn on. It is a "bit" oriented protocol that requires hardware beyond normal PC type devices. If you haven't used it previously, strongly recommend using our asynchronous format. The SDLC and Non-SDLC differences are described in detail in an application note on the HGuide Gitlab site. Contact HGuide.Sales@Honeywell.com for access.
